Favorite Motorcycle Auctions of 2025
About this episode
A lively discussion on the favorite motorcycle auctions of 2025 unfolds as hosts Alex Porter and Tyler Greenblatt dive into the latest trends and highlights in the motorcycle auction scene. They share insights on the impressive growth of motorcycle auctions, reaching over 11,000 listings, and reflect on the artistry and engineering behind motorcycles, especially pre-war models. The episode features a personal touch with favorite bikes and exhaust systems, while also touching on the evolution of Harley-Davidson's engineering, including their transition to liquid cooling. It's a blend of passion, expertise, and the aesthetic appreciation of motorcycles.
Last year was, almost inarguably, our best year ever for motorcycle auctions. This week on the podcast, Alex and Tyler discuss each of their top 10 bikes of the year.
Along the way, they touch on a public transport admission; daily and weekly firsts; the care taken to design parts that will always be visible; their favorite exhaust systems; scaring horses off roads a century ago; the difficulty in modernizing the Harley-Davidson; left-hand throttles and Colt Pythons; Bimota and Harley trivia; odd partnerships and engine configurations; and a great run of big pre-war, air-cooled fours.

emissions requirements
"But it's just enough so that they can run them just to within like emissions requirements. Yeah, yeah, yeah."
Emissions requirements are rules that cars must follow to make sure they don't pollute the air too much. They help keep the environment clean by limiting harmful gases from vehicles.
Emissions requirements are regulations set by governments to limit the amount of pollutants that vehicles can emit into the atmosphere. These standards are designed to reduce air pollution and protect the environment.
push to start
"Which I think if you buy a 992 Turbo, you still have the push to start on the left side. Is that true? I think so."
