Does a Longer Stroke Make More Torque?

Find us on Patreon! https://www.patreon.com/cw/CycleWorldPodcastEvery superbike and MotoGP bike Ducati has made in the last 50-plus years owes it all to the company's first successful V-twin racer: The 1972 Imola 750. The Imola 200-mile race was the coming out party for Ducati's 750 Imola racebike, designed and led by the great engineer Fabio Taglioni. It was the motorcycle Ducati needed to stay in business, and the win showed it was exactly the right bike at precisely the right time, all the way down to its bevel-driven overhead-cam desmodromic valve system. It's a story of financial woes, drama, and an unlikely success that set Ducati on a path it maintains today. Join Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer as they talk about the Imola 750 and Hoyer's chance to see one of the original eight bikes in person with Mecum Auctions as that example gets prepared for the Monterey Car Week Auction August 13-15.

Find us on Patreon! https://www.patreon.com/cw/CycleWorldPodcastThe US motorcycle market is a market of love. Performance stats, spec sheets, MPG, or other more practical concerns have a role, but it's usually to support and justify buying THE MOTORCYCLE WE LOVE. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer talk about motorcycle styling, car styling, "covers" on appliances, and more. They also consider that motorcycles at the very least have to be more honest than cars in what they represent underneath their skin. Find out if you agree and we'll see you in the comments!

Learn about "the wedge" and maybe that modern vehicles are "liars"?

Honda superbikes were established as V-4s in the early 1980s, but when Honda Motor Co. saw Ducati winning with a V-twin in World Superbike, it build a new V-twin engine for the 2000 season. And won. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer talk about the origins of the RC51, also known as the VTR1000 SP1/SP2, and its World Superbike championships in 2000 and 2002.

Aerodynamic aids will be dialed back, and ride-height mechanisms will not be not allowed. There are more rules going into effect than this, so take a ride with us to hear what we might expect in 2027.

Kevin and Mark take a tour through rear suspension systems that didn't work and never beat the simplicity of the conventional swingarm, plus they get into all kinds of other elements of the chassis.

Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer talk about Bore and Stroke Ratio and how it influences engine horsepower and torque.

What is a beautiful motorcycle? You know it when you see it? Kevin and Mark talk about beauty of motorcycles both inside and out. We have a lot of the hits--Vincent Black Shadow, Harley-Davidson XR-750, Norton Manx, and more--but they sneak in some unusual stuff, too, all the way to the 1967 Suzuki RK67 50cc roadracer with 17-speed transmission!
