Leave it to Technical Editor Kevin Cameron to start in 1862 with the first guy who conceived the four-stroke combustion cycle. KC proceeds with Editor-in-Chief Mark Hoyer on the journey to the combustion chamber we have today and why it's shaped how it is, flatheads to hemis, two valve, four valves and more valves! There's so much to cover in such a small space. Join us!

Motorcycle manufacturers made some strange experiments as they looked for new customers or that novel idea that would create a new type of machine. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer go down a list of odd and wonderful machines that made it to the market--sometimes not for very long. Did you know about the two-wheel-drive dirtbike? The cruiser with the fabulously expensive front suspension? What's a Monotracer? Watch now and join us on this oddball journey.

What causes a world championship-winning rider/team owner to quit the factory racing world and build his own engines and chassis? FREEDOM! Kenny Roberts took the considerable talent of his Yamaha factory team and forged ahead alone, first with the Modenas KR3 and then the Proton KR5. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer talk about the development of these bikes, and manage to get a few other Alternative Engines in such as the Aprilia Cube three cylinder. Listen now!

Suzuki found early Grand Prix success with two-strokes in the early 1960s and it bloomed into 500cc championships in the '70s, '80s, and '90s and 2000s with riders like Scheene, Uncini, Lucchinelli, Schwantz and Roberts. Suzuki even scored one in MotoGP's four-stroke era. Technical Editor Kevin Cameron and Editor Mark Hoyer talk about Suzuki's early days in GP racing and the Hamamatsu company's rise to the top.

Honda's VF750F arrived in 1982 with is square-tube steel frame that elevated the motorcycling handling game to new heights and launched a production V-4 dynasty at Honda. AMA Superbike championships followed as did many remarkable motorcycles including VF1000R, RC30, RC45, VFR750, 800, and 1200, plus the amazingly exotic oval-piston NR750. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer discuss the origins of the V-4 and its successes and failures.

Triumph died along with the British motorcycle industry in the 1970s, with last-gasps into the 1980s. Then John Bloor came along and breathed new life into the storied British brand. And it wasn't some half-hearted retro effort, the company jumped right into modern motorcycles. Now, the company is a Moto2 engine supplier, has a full high-performance retro line, a collection of sporting streetbikes and the world's largest-displacement cruiser. It's even making 450 and 250cc motocrossers! Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer talk about the resurgence and evolution of Triumph from the 1990s to the present.

There is so much old technology people think is new that it didn't fit in one episode! So join us for our second round of interesting motorcycle and engine technology that seems new but absolutely is not. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer hit the podcast running with roller tappets...Listen to hear about those and the rest of the items on the list!

BMW got serious about making motorcycle engines in 1923, when aircraft engine designer Max Friz delivered the first flat-twin to BMW. More than 100 years later, the Boxer engine remains the soul of BMW despite the company's success with many other engine layouts including the inline fours and sixes, plus singles and parallel twins. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer discuss the evolution from that first flat twin to the remarkable R 1300 that powers the new R 1300 GS, R 1300 RT, and more.

Long before King of the Baggers, Harley-Davidson committed to Superbike racing and hit the track in the early 1990s with the VR1000. This 1000cc V-twin had all the right ingredients for success, but what happened? Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer take a dive into the building of the bike, its evolving specs, it ultimate retirement and so much more!

Glenn Curtiss was one of the great innovators of motorcycling and aircraft in the early days of the combustion engine. His V-8 and V-12 aircraft engines were legendary and record-setting on earth and in the sky. Technical Editor Kevin Cameron rates Curtiss as a hero, and Editor-in-Chief Mark Hoyer agrees. We also have excellent technical information about land speed racing from a engineer/racer Wes Orloff who also rates Curtiss as a hero, and we examine Curtiss' speed record set on a beach in 1907.
