Re-Release: Jeremy Burgess - 46 years on

Jeremy Burgess is an Australian motorcycle racing mechanic and crew chief known for helping riders win at the highest level of MotoGP. In this episode, he’s credited with guiding Valentino Rossi and developing race bikes across multiple manufacturers.

MotoGP is the top tier of Grand Prix motorcycle racing, featuring the fastest factory and satellite teams. When the host says “what we now know as MotoGP,” they’re pointing out that the series has evolved in name and structure since 1980.

Randy Momola is a former professional Grand Prix motorcycle racer. In this segment, he’s described as 20 years old when he earned his first Premier Class win, with Jeremy Burgess working as his mechanic on a Suzuki.

Suzuki is a major Japanese motorcycle manufacturer that competes in Grand Prix racing. Here, the host notes Jeremy Burgess worked as a mechanic for Randy Momola on a Suzuki during his early MotoGP-era success.

The Belgian GP is a Grand Prix motorcycle race event held in Belgium. In this episode, it’s the specific race where Jeremy Burgess scored his first win in the era that later became MotoGP.

“Premier Class” refers to the top category in Grand Prix motorcycle racing at the time. The host uses it to emphasize that Randy Mamola’s win was in the highest competition level, not a lower support class.

Valentino Rossi is one of the most famous motorcycle racers in history, known for long-term success in MotoGP. In this episode, Jeremy Burgess is credited with guiding him through major wins and titles, including the era when Rossi rode 500cc machines.

Graziano Rossi is the father of Valentino Rossi. The host mentions him as being in the field at the time, setting up the later “Valentino would rise…” storyline.

A crew chief is the senior team leader responsible for race-day strategy and technical direction for a rider—coordinating setup changes, communication, and development priorities. In MotoGP, the crew chief’s job is tightly linked to translating rider feedback into faster lap times.

“500cc” refers to engine displacement measured in cubic centimeters, used here to describe the class of MotoGP-era bikes Rossi was racing. It’s a shorthand for the bike’s size/format at the time, which affects how the engine makes power and how the bike behaves.

Adelaide is the capital city of South Australia. In this episode, it’s mentioned as the planned host location for the Australian motorcycle Grand Prix to be staged as a street race in 2027.

A street race is an event where racing takes place on public roads that are temporarily closed and adapted for competition. Compared with a purpose-built circuit, street races often involve tighter corners, different surface conditions, and less room for mistakes.

The Australian motorcycle Grand Prix is a major MotoGP event held in Australia. The host says it’s set to become a street race in Adelaide in 2027, highlighting a format change from a traditional circuit.

A Suzuki T500 is a classic 500cc two-stroke motorcycle model. Jeremy Burgess calls it his first road bike and specifies it as a 1969 model, which matters because the T500 era is known for punchy two-stroke power and a very different feel than modern four-strokes.

The Kawasaki H2 is a legendary 750cc two-stroke “triple” motorcycle known for strong, abrupt power delivery and a reputation for being fast and demanding. Jeremy Burgess says this was his first race bike in 1972, which frames it as a serious step up from casual riding.

A “podium” finish means placing in the top three of a race (first, second, or third). The speaker frames their first podium as a major milestone in their racing career.

Zolder is a motorsport circuit in Belgium known for hosting motorcycle and car racing events. In this segment, it’s the venue where the speaker recalls the first podium in their career.

In racing, “testing” is structured track time used to evaluate setup changes, tire choices, and performance. Here, the team’s testing led them to break lap records, confirming the rider’s pace and the bike’s competitiveness.

“Lap records” are the fastest times recorded for a single lap of a specific circuit. In racing, teams track lap records to judge whether a bike or car has the speed and setup to be competitive.

“Spa” refers to Circuit de Spa-Francorchamps in Belgium, a famous Grand Prix venue. The speaker says the event was normally at Spa, but issues with the track condition in 1979 led them to choose Zolder instead.

“500 Yamaha” refers to a Yamaha motorcycle in the 500cc class (a top-tier Grand Prix category in that era). The speaker notes that Freddie Spencer even showed up at the race on a 500 Yamaha.

Honda is a major Japanese motorcycle manufacturer and racing engine/bike supplier. In this segment, “Honda” refers to the racing program Jeremy Burgess joined in 1983 and the team context around Freddie Spencer and Irv Kanemoto.

The Daytona 200 is a famous motorcycle race held at Daytona International Speedway. It’s a high-profile event where teams test race setups and rider-machine performance under long-distance sprint conditions.

“Laguna” here refers to Laguna Seca, a well-known road course in California used for major motorcycle and car racing. Its mix of corners makes it a useful benchmark for how well a bike’s setup works.

A gear ratio is the relationship between the transmission gears that determines how many engine revolutions happen for each turn of the wheel. Changing it can shift the bike/car’s balance between acceleration and top speed, and it’s often tuned for specific track sections.

“George” is mentioned as part of the speaker’s inner circle while discussing work and career moves. The transcript doesn’t provide George’s last name or role, so listeners may not know who he is in the racing context.

“Irv” is referenced as someone giving career guidance and discussing timing (“within sort of 24 hours there was another phone call”). The transcript doesn’t identify Irv’s full name or job title, but he appears to be a key decision-maker or mentor figure.

Wayne Gardner is a top-level motorcycle racer discussed here in the context of Honda’s racing program. The speaker describes him moving into a factory team and becoming the number one rider after a teammate’s season went badly.

A “factory team” is a racing team directly supported by the motorcycle manufacturer (here, Honda). Factory teams typically have the most resources, engineering input, and access to the latest development parts.

Freddie Spencer is named as the expected “number one rider” in the Honda factory team. The speaker says Spencer’s 1986 season (“Freddie's 86”) was a disaster, which changed team dynamics and elevated Wayne Gardner.

“Factory design” refers to the manufacturer’s engineering plans and development work for the race bike. The speaker contrasts factory design work with the team’s job of implementing it correctly in the real-world race setup.

Hockenheim is a famous German racing circuit known for long straights where top speed matters. The speaker brings it up to explain where the 500cc two-strokes could “unleash” their power.

Monza is an iconic Italian circuit famous for very high-speed racing and long straights. It’s often used as a benchmark for top-end speed, which is why the speaker mentions it when discussing two-stroke power.

“Unleaded fuel base” refers to switching the racing fuel formulation away from leaded components to an unleaded specification. The speaker says this change cost some horsepower, which is a common tradeoff when fuel chemistry changes engine tuning and combustion behavior.

“196 horsepower” is the engine’s measured power output. In this context it highlights how strong the 500cc two-stroke racing bikes were, especially since the speaker notes there was no electronics controlling or smoothing the power delivery.

“No electronics” means the bike didn’t rely on modern electronic engine management systems (like advanced fuel/ignition control, traction aids, or ride-by-wire). That makes the machine more mechanically “raw,” so setup and rider skill matter even more.

“Plated immediately” refers to using a plate (typically metal) to stabilize a fractured bone right away. In trauma care, early stabilization helps protect healing and can reduce complications, which matters for a rider trying to recover quickly.

The “80-20 theory” is a rule-of-thumb used in motorsport to argue that most race results come from the rider (about 80%) rather than the machine (about 20%). In other words, rider fitness, skill, and stamina can outweigh small technical advantages from the bike.

Fuel injection is an engine system that precisely meters fuel into the engine using electronic controls instead of relying on a carburetor. In motorcycles, early-season fuel-injection calibration can strongly affect throttle response and power delivery, which is why riders and engineers may struggle until it’s sorted.

In motorcycle setup, suspension is the system that controls how the bike absorbs bumps and how it stays stable under braking, cornering, and acceleration. Changes to the suspension can dramatically alter the bike’s handling feel and traction.

A shock (typically the rear shock absorber on a motorcycle) is a key suspension component that controls damping—how quickly the suspension compresses and rebounds. Swapping shocks can change ride height, traction, and how quickly the bike settles after hitting bumps.

Pole position is the starting spot at the front of the grid, awarded to the fastest qualifier. In motorcycle racing, starting from pole can strongly influence race strategy and early track position.

Double clutching is a shifting technique where the driver uses the clutch twice during one gear change. It’s especially useful with an unsynchronized manual gearbox because it helps match engine speed to the next gear, making the shift smoother and easier to complete.

An unsynchronized manual gearbox (often called a “crash box”) lacks synchronizers that automatically match gear and shaft speeds. Without synchronizers, the driver must use techniques like double clutching to reduce gear clash and make shifts possible.

“Double shuffle” is a nickname for the same double-clutch shifting sequence: clutch in, shift to neutral, clutch out, then clutch in again to complete the gear change. The term emphasizes the two “moves” the driver makes during one shift.

Grand Prix wins refer to victories in top-level motorcycle road racing events that make up the season. Each race is a “Grand Prix,” and the total number of wins is a key measure of a rider’s success.

The FSO 125 is a compact car produced by FSO, and it’s often discussed in the context of older, simpler vehicles and how they’re driven or maintained. The “125” name typically points to its engine size class, and the car’s layout makes it a good platform for learning driving technique and maximizing performance within its limits. In the podcast context, it’s likely referenced because someone learned specific habits on these 125s to get the most out of them.

In motorcycle racing, the frame is the main structural chassis that locates the engine, wheels, and suspension. Frame changes affect stiffness, flex, and geometry, which can dramatically change steering feel and traction.

A swing arm is the pivoting rear suspension arm on a motorcycle. Changing the swing arm can alter rear-wheel position, suspension geometry, and how the bike responds under braking, corner entry, and acceleration.

Porting is modifying the intake and exhaust passages in an engine to improve airflow. In performance engines, porting changes how efficiently the engine breathes at different RPMs, which can shift power delivery and throttle response.

“V5” describes an engine with five cylinders arranged in a V shape. It’s unusual compared with more common V4/V6 layouts, and it can influence packaging, firing order, vibration characteristics, and how the engine delivers power.

Cowling is the aerodynamic bodywork around an engine or front area on a motorcycle. Less cowling can reduce weight and cooling drag, but it can also increase airflow disruption and make the bike harder for a rider to control at speed.

A wind tunnel is a testing facility that measures aerodynamic forces by pushing air past a vehicle or component. Teams use it to refine shapes for drag reduction and stability, especially when rider comfort and control at speed are affected by airflow.

A four-stroke engine completes its cycle in four piston strokes (intake, compression, power, exhaust). In motorcycle racing, switching from a two-stroke to a four-stroke changes how power is delivered and how the bike behaves under braking and cornering.

A two-stroke engine produces a power cycle in two piston strokes, typically giving a different torque and acceleration character than a four-stroke. The speaker contrasts the two-stroke’s advantages in cornering/braking with the four-stroke’s stronger overall usability for passing and power delivery.

The Honda RC 211 was a MotoGP race bike associated with the transition to four-stroke racing in the early 2000s. The speaker is describing development work to make the RC 211 more comfortable for Valentino Rossi, including changes tied to the engine and power delivery.

Fly-by-wire throttle means the rider’s throttle input is converted into electronic signals rather than directly moving a mechanical linkage. In racing, this enables more precise control strategies—especially when combined with traction control—to manage wheel slip.

Traction control is an electronic system that reduces wheel spin by modulating engine power when it detects loss of grip. On a race bike, it helps maintain acceleration without the rear wheel breaking traction, which can improve lap times and consistency.

A slipper clutch is a motorcycle clutch setup designed to reduce rear-wheel hop and lockup during hard downshifts. It “slips” slightly under engine braking so the bike stays more stable when you brake and shift at the same time.

“Hierarchy” here refers to the internal leadership structure of Yamaha’s racing organization—team management and decision-makers. “Clandestine meetings” suggests these were behind-the-scenes discussions among key people about the rider/bike program.

Throttle bodies are the air-control housings on an engine or engine system. They regulate how much air enters the intake, which directly affects engine power and response.

A guillotine-type slide arrangement refers to a throttle/air-control mechanism where a flat “blade” or slide moves to open and close airflow. In racing applications, the design can influence throttle response and how smoothly the engine breathes under different conditions.

An inline four is an engine layout with four cylinders arranged in a single straight row. It’s commonly used in motorcycles and cars because it can be compact and smooth, but its packaging and airflow can be compared against other layouts in racing.

The Honda Beat is a small, lightweight sports coupe made by Honda, known for its compact size and fun, go-kart-like driving feel. It often comes up in conversations about unusual, enthusiast-focused cars because it’s designed to be nimble rather than powerful. In a podcast, it may be mentioned as an example of a “beat” challenge or a car people associate with Honda’s playful performance reputation.

A V4 is an engine layout with four cylinders arranged in a “V” shape. The V-angle and cylinder packaging can affect balance, vibration, and how the engine fits in a race bike or car.

In engine engineering, friction refers to the resistive forces inside the engine that waste energy (for example, between moving parts). Lower friction can improve efficiency and power output, regardless of cylinder layout.

“Turbo years” refers to an era in racing when turbocharged engines were prominent. Turbocharging changes how power is made by forcing more air into the engine, which affects design tradeoffs like heat management and friction.

Brembo brakes are high-performance brake systems made by the Italian brake specialist Brembo. In racing, they’re known for strong stopping power and consistent brake feel under heat, which matters when riders are pushing hard and braking late.

Wheel lock happens when a wheel stops rotating during braking, usually because braking force exceeds tire grip. On motorcycles, avoiding wheel lock helps maintain steering control and stability, especially under hard braking.

Phillip Island is a famous motorcycle racing circuit in Australia, known for fast corners and changing grip. It’s a common venue for testing race setups because weather and track conditions can vary, making traction and engine response critical.

“Torquey bottom end” describes strong engine pulling at low RPMs (the lower end of the rev range). In racing, that can help a rider accelerate out of corners and get the bike moving quickly before higher-RPM power takes over.

In motorcycle tuning, “power delivery” describes how the engine’s output comes on as you open the throttle. A more linear power delivery means the bike responds smoothly and predictably rather than surging or lagging.

Yamaha is a Japanese motorcycle manufacturer that competes at the highest levels of racing. In this segment, Yamaha is tied to the team’s development work and the push to win championships across different seasons.

Qatar is referenced as the race location where the team expected difficulty due to extreme heat. Track conditions and ambient temperature can heavily affect engine and fuel-system performance.

Ducati is an Italian motorcycle manufacturer known for performance-focused engines and distinctive engineering. In this segment, the speaker contrasts Yamaha and Ducati as the bikes involved in championship-winning development.

“800” refers to the 800cc class era in motorcycle racing, where engine displacement rules shape bike design and development priorities. Changes in the displacement/era can make one manufacturer’s package suddenly more competitive.

Bridgestone is a major tire manufacturer, and “Bridgestone tyres” here means the race tires supplied by that brand. Tire choice strongly affects grip, heat management, and ultimately lap times and consistency.

In motorcycle racing, “electronic components” usually refers to onboard electronics that control or assist performance—things like engine management, sensors, and traction-related systems. They can be expensive to develop and integrate, which is why teams and manufacturers may pace spending over multiple seasons.

“Fuel saving” in racing refers to strategies and engine/ride-control settings that reduce fuel consumption without sacrificing too much speed. In series with fuel limits or strong penalties for overconsumption, it can directly influence race tactics and lap-by-lap performance.

“Freezing fuel” is a racing development concept where fuel temperature is lowered (often via cooling) to improve combustion consistency and performance. Cooler fuel can change how the engine responds, and teams may use it as part of a broader efficiency/performance package.

“Jucati” appears to be a transcription of Ducati, the Italian motorcycle manufacturer. The speaker credits Ducati with being first to develop and normalize certain electronics and fuel-efficiency ideas that later became common.

“Engine character” is the feel and behavior of an engine—how it delivers power across the rev range, how smoothly it responds, and how it transitions between throttle positions. In motorcycle racing, that can strongly affect traction and stability because the bike’s grip and suspension loading depend on how the engine responds to throttle.

“Melandria Max” appears to be a rider or team reference in the Yamaha discussion, used to describe who couldn’t agree on whether the issue was engine or chassis. Because the name is unclear in the transcript, it’s likely a transcription error or nickname.

A “prototype” is an early, test version of a race bike built to evaluate performance and development changes before it becomes the final race-ready package. The speaker contrasts prototype testing with jumping straight to race bikes, implying the team needed more iterative development time.

The Corkscrew is a signature corner at Laguna Seca: a steep downhill section that riders must thread through while braking and setting up for the next turn. Because it’s so distinctive, it often becomes a prime passing spot and a focal point in race highlights.

The paddock is the area at a motorsport event where teams and riders operate between sessions—think garages, hospitality, and team personnel. It’s also where riders and teams talk strategy and where rumors or reactions to race incidents spread quickly.

“Second to lap faster” means the rider was about one second quicker per lap than the competition. In racing, per-lap time gaps are a key way to judge pace and how likely someone is to close in or pass over multiple laps.

Race strategy is the planned approach to how you’ll ride the race—things like when to push, how to manage tires/fuel, and how to position yourself relative to other riders. In MotoGP-style racing, strategy often matters as much as outright speed because passing opportunities can be limited by track layout.

The Jaguar XK engine is Jaguar’s famous inline-six engine family from the post-war period, widely celebrated for its performance and smoothness. Burgess specifically describes it as a six-cylinder, double overhead camshaft design with hemispherical combustion chambers.

A double overhead camshaft (DOHC) engine uses two camshafts in the cylinder head to control the intake and exhaust valves. This layout can improve breathing at higher engine speeds compared with simpler single-cam designs.

The Jaguar Mark II is a classic British saloon known for its refined styling and, in many versions, the XK engine family. In this segment, Jeremy Burgess connects it to Jaguar’s post-war engineering and says he later bought one and rebuilt it from the ground up.

Hemispherical combustion chambers are shaped like a half-sphere, which can allow better airflow and more efficient combustion. This design is often associated with strong performance because it supports efficient valve placement and mixture motion.

The Triumph TR4 is a classic British sports car that Burgess mentions as his backup plan when he couldn’t find a good Jaguar Mark II. It’s a different kind of car than the Jaguar saloon, but it shows the alternatives enthusiasts considered in that era.

Ultra-Tune is an automotive service brand known for tune-ups and engine servicing. In this context, Burgess took the car to an Ultra-Tune after buying it, implying he had it checked and set up for proper running.

An angle grinder is a handheld power tool with a rotating abrasive disc used to cut, grind, or strip material. Here, it’s used to remove hidden body filler/repairs so the underlying rust can be found.
