Inside Ducati's Insane NEW 2027 SUPERLEGGERA Centenario! All the CARBON FIBER and 248 HP!
Ducati dropped a carbon-fiber bomb in the form of the 2027 Superleggera Centenario, the most exotic V-4 superbike from Borgo Panigale ever. Perhaps even more far out than the Ducati Desmosedici RR just because there were no "rule" limitations for the new Superleggera. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer dig into all the details of this beautiful and exotic limited-production Ducati, all the way down to the ceramic brakes and the special oil that helps the bike produce a claimed 248 hp. Thank you for watching!
Motorcycle Rear Suspension and the Evolution of the Swingarm.
Listening to our listeners (and viewers), this topic came from you guys: Kevin and Mark take a look at motorcycle rear suspension starting with "all arm and no swing" rigid frames of the early days to the many variation on the swingarm as we know it today. A sprung saddle is "rear" suspension, no?
WEIGHT TRANSFER and Motorcycle Handling--To wheelie or not?
How many ways have motorcycle designers gotten it wrong? So many! One of these was chasing an ultra-low center of gravity on motorcycles, only to find it made handling worse! How have we settled on 20-22 inches off the ground for center of gravity? Because it works, and transfers weight on the front wheel during braking and to the rear wheel when accelerating. The right C of G also assists us when tipping into a corner. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer discuss motorcycle weight transfer and motorcycling handling. Our favorite moments of weight transfer? Wheelies and stoppies, of course!
MOTORCYCLE GEARBOXES EXPLAINED: Shifting, gear mesh, forks and more.
The motorcycle gearbox can be a great mystery but Kevin Cameron is here to help us all understand how it works. Why do we have six-speeds and constant mesh (mostly)? Kevin and Mark Hoyer also divert into DCT, helical gears vs. spur, and how to make your dogs happy. Join them for another Cycle World Podcast.
BIG BANG! How Firing Order Can Change An Engine.
Honda made a big impression with its close-firing-order "big bang" NSR500 and became dominant in two-stroke 500cc Grand Prix racing through the 1990s, replacing the "screamer" engine. Other factories followed suit. But firing order on four-strokes also plays a huge role in how an engine works and how it relates to the rider and to traction. How? Join Cycle World Technical Editor Kevin Cameron and Editor Mark Hoyer as they talk about Big Bang, Yamaha Crossplane, "Twingles," and the all-important "MORE"!
Why did the "Normal" valve win? Poppet valves vs. Sleeve Valves vs. Rotary valves.
There have been many engine valve designs since the dawn of the internal combustion engine. What made poppet valves stick? (See what we did?) There were many other designs and some, like the sleeve valve in the Bristol Centaurus WWII radial aircraft engine, that worked very well. Classic Kevin Cameron stuff here as he and Mark Hoyer discuss the relative merits of engine valve types.
Four Banger: How the inline-four was inevitable for motorcycles.
The inline-four has many qualities that made it the performance engine format of choice for decades. Ride with Kevin and Mark as they talk about the origins of the inline-four and how we have explored many other engine formats and firing orders/timings, and possibly a few side stories about other things!
Hello Sparky! History of Ignition, Spark! Open Flame! Hot Tube! What?!
We just want to light the fire, that's it! Kevin and Mark dive into all the different ways internal combustion engine builders have found to light the combustible air/fuel mixture. There has been spark, open flames(!), a thing called "hot tube" and more. Even compression can light off the charge, and we'll talk about that too. From magnetos to coil and points to fully electronic coil-on-plug ignitions with upward of 60,000 volts, we try to cover it all. Join us for the latest Cycle World podcast!
Why Steel Pistons and Cylinder Heads? Why Now?
In the early days of internal combustion engines, pistons were typically made of steel, but it wasn't long before aluminum took over (thanks, W.O. Bentley). But steel pistons and even cylinder heads are coming back in special applications. Kevin and Mark dive in to 3D printed steel pistons, turbo housings, and steel cylinder heads in F1 and other racing. The guys take a deep dive into boost, piston temperature, lean burn, diesel, additive manufacturing and so much more.
Torque! Tolerance! HOW HARD DO WE TURN THE WRENCH?! Feel? Force? Learn about tightening bolts.
"Don't want it to come loose!" This is true, but how many mangled fasteners and engine cases have you encountered? More than you'd like. So Kevin and Mark decided to talk torque, torque wrenches, lock nuts, fastener elasticity, sealing, and so much more. And what if you don't have a torque reference sheet for your bike? Learn fastener basics to help you have guidelines for fastener type and material, too. Lot's to talk about here. Grab your torque wrench and join us for the Cycle World podcast!
Why OVERHEAD CAMS and How Did WE GET HERE?
Kevin will start with atmospheric intake valves and someone from the 1800s, but for real we are talking about Overhead Cams here. Why has OHC become the standard for four-stroke-engine valve operation and what are its advantages. Also, you won't believe how old the technology is. Join Kevin and Mark for the bumpy world of cams above the head.
Piston Rings! The Tiny Parts that Make Piston Engines Possible!
Early attempts at sealing pistons in cylinders included hemp and other natural fibers. Today's piston rings are made of amazing metallic materials that allow motorcycle engines to last longer than ever. Kevin and Mark dive into piston rings from the early days to now and talk about cylinder finish, ring gap, "flutter," and so much more. Join them on the Cycle World podcast!
Are Racers and Crew Chiefs Human? Inside the minds and talents of the world's best!
In this week's episode, Cycle World Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer talk about racers and crew chiefs and how their seeming supernatural powers relate to their humanity. Also, we have learned so much from these talented, intelligent people and share many stories about some of the greatest road racing riders and tuners of all time, how they win and how they progress. Join us!
MORE Dream Bikes from the Mecum Las Vegas Auction 2026!
Hey, there are more than 2000 bikes, and Kevin and Mark picked so many bikes for the first episode of the 2026 Mecum Las Vegas motorcycle auction that they wanted to keep going! Honda NSR400 to Vincents to one sweet Yamaha TR-2 350cc roadracer, it's another good time with some amazing bikes.
Are HYBRID Motorcycles Dumb?
Hybrid power can bring the best of electric and combustion power together, but does it make sense for motorcycles? Benda recently showed a hybrid prototype and Kawasaki has already taken the plunge. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer discuss hybrid power, including diesel electric trains and a Canadian company doing similar work on semi-trucks and a diesel hybrid pickup truck to retrofit your full-size bike hauler. Hop on and ride with us!
DREAM BIKES: Kevin & Mark's favorite Bikes from the Mecum Las Vegas Motorcycle Auction!
Kevin and Mark pick their favorite bikes from the MASSIVE Mecum Las Vegas Motorcycle Auction. Of course, Kevin picked technically interesting and historically significant bikes, and Mark picked "stuff he liked"! There are great bikes here and plenty of stories to go with them. Harleys, Hondas, a Buell and stuff you may not have heard of. Join us on the ride!
