Every 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.

The 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!

At its core, Honda tries things. 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.

Purpose-built production racebikes were available and pretty affordable in the early-to-mid 1970s, but humans will race just about anything. So as streetbikes started to improve and the term "superbike" was born, it didn't take long for people to start racing production bikes at local tracks. One of the most famous was Cook Neilson and Phil Shilling's Cycle magazine Ducati was born as the California Hot Rod, while Butler & Smith BMW's Udo Gietl turn the R 90 S into a race- and championship-winning bike. Kawasakis and more hit the race track, too. At first, modifications were limited, but once the first AMA Superbike Championship was launched in 1976--an idea and its class rules born on an empty California apartment floor in 1975 between John Ulrich and Steve McLaughlin--the motorcycles evolved quickly. Join Technical Editor Kevin Cameron and Editor-in-Cheif Mark Hoyer for a discussion about the birth of the Superbike.

Kevin and Mark talk about Daytona from early days at the beach, moving to the Speedway, and with lots of anecdotes thrown in. Mark was there for the race weekend this year, celebrating 50 years of AMA Superbike racing with BMW, which won the first superbike race at Daytona in 1976 and won the first championship that year, with its R 90 S, built by Butler & Smith. History was also made in the 200, as Kayla Yaakov became the first woman to finish on the podium, and she rode an absolutely excellent race to do it.

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.

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!

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"!

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.

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!

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.
