Kawasaki Debuts Supercharged Four-Cylinder Engine

The start of the Tokyo Motor Show is today, if you haven’t already noticed, and it looks like the Japanese OEMs have saved their best models for the home court advantage this year, with all four of the Big Four having something special for Tokyo.

Yamaha’s big announcement of course is the nearly-ready-for-production Yamaha R25 concept, a 250cc two-cylinder sport bike that Valentino Rossi says “packs quite a punch.” The tuning fork brand also has its more fanciful concepts to show-off, chiefly the Yamaha PES1 electric street bike and the Yamaha PED1 electric dirt bike.

Suzuki is in the mix as well, with its turbocharged Recursion concept, as well as its electric monkey bike, the Extrigger concept. Both of these motorcycles look like a hoot to ride, for very different reasons of course.

Not wanting to be left out on the forced-induction warpath, Kawasaki has its own blower for the two-wheeled world. Showcasing a supercharged four-cylinder engine at its booth, Kawasaki says it developed the turbine and motor in-house, and hints that we will see this in a motorcycle model in the near future.

Details beyond that are scarce, with Kawasaki’s official party line being the following:

Kawasaki Heavy Industries, Ltd. also has a long history of developing technologies for turbine engines. The lifeblood of these turbines is their blades, which need to be able to cope with extreme heat and vibration while spinning at high speeds.

Know-how from years of designing turbine engine blades was instilled in the first supercharger developed by a motorcycle manufacturer. And of course, designing a motorcycle-use supercharged engine in-house means that maximum efficiency could be pursued.

Still, it should be interesting to see what Kawasaki cooks up, as forced-induction bikes could pack some good horsepower into some small packages. Lighter, faster, stronger, harder…gentlemen, we have the technology.
