Sounds crazy but early engines ran on "city gas," generated by roasting coal. Liquid fuels like gasoline improved our lot in Combustion Life, but there have been many experiments to get the most out of it. How close are we to perfect combustion? How do we get liquid fuel--which will not burn--to turn to vapor that will burn? So many questions that Kevin and Mark set out to answer. Let's get into the molecules, shall we?
How "Ninja" came to define Kawasaki and what it means to the company. The bikes that built this brand within the brand started in the early 1970s and Ninja just put a name on it. What's "it"? Listen as Kevin and Mark of Cycle World talk about where the Ninja ethic began and where it's taken Kawasaki, from screaming two-stroke triples to supercharged 1000cc sportbikes.
This week Kevin and Mark are getting MORE MOLECULAR than usual! We know, it's awesome, right? The motorcycle mostly started with iron, then steel and some bronze, and then we got aluminum, titanium, beryllium and more, plus all kinds of composites. Despite getting molecular, it's a big topic, so join us on our epic journey.
Yamaha is a passionate racing company but recent success has eluded the tuning fork folks. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer dig into Yamaha's new V4 MotoGP racer that debuted at Misano and is under continued testing. Will the V4 solve all the company's problems? Will rides love the new engine and bike? What are the advantages and disadvantages of V4s and inline-4s. Listen to find out!
Kevin and Mark dive into what's holding back the ULTIMATE PERFORMANCE of your motorcycle. What could be changed in the engine or with aerodynamics that could help us hit 250 mph? What are the tragic shortcomings and amazing strengths of motorcycles today? Jump in the slipstream and take the ride with us on the Cycle World Podcast.
Engine vibration...does it eat horsepower? How do we control it? Where does it come from? What's secondary vibration vs. primary? Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer discuss the many types of vibration in engines and the various schemes used to control it or let those vibes we love come through.
The little step-through that changed transportation around the globe and helped Honda achieve Grand Prix Racing success, technical dominance, and massive wins in automobiles, the 1958 Super Cub hit a target for buyers no one had yet considered. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer discuss how Soichiro Honda and Takeo Fujisawa helped conceive of this little motorcycle to function easily in broad conditions and the unique features that helped it fly off the showroom floor from the very beginning.
All we've ever wanted is complete control of combustion in our motorcycle engines and we are closer than ever. Find out how cleaning up emissions has enhanced power, running quality, engine life and more as Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer discuss the combustion process and all the tricks used to move ever closer to stoichiometric. What's that? Listen and find out. Also, there's a chance someone might say "Velocette" or "TZ750," so don't miss it!
Barn finds, garage finds, yard finds and alley finds, that abandoned old motorcycle isn't going to start itself! Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer run through the steps and tricks to get an old carbureted or fuel-injected motorcycle running. Two-stroke oil in a four-stroke? Yes! De-rust a gas tank--we have a way! Listen as discuss the smell of old gas and getting a motorcycle out of the barn and back on the road.
Concept bikes can be crazy weird looks at a possible future or be hints about new models to come. Some are even intended as near-production but never make it. Technical Editor Kevin Cameron and Editor-in-Chief Mark Hoyer run down a list of 10 concept bikes that might have been and one that actually made it to the streets of America. Hybrids, superchargers, inline-sixes, alternative front suspensions, and one called "Biplane"?! And if it has four wheels but leans, is it still a "motorcycle"?
If every combustion event in your motorcycle engine was the best it could be, power and efficiency could rise by as much as 20 percent! Find out how engineers and designers work toward this optimal goal and how chaos just keeps getting in the way. Technical Editor Kevin Cameron and Mark Hoyer talk about all the things that influence how the charge lights off in the cylinder of your motorcycle engine.
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!
