Search the past threads for EX500, there have been a couple of discussions on this topic. In short summary Dirt Wheels did a test on a one-off machine created for a Kawasaki exec on a Mojave chassis with an EX500 motor shoehorned in. The motor predictably ripped but the Mojave platform was badly out-taxed by the machine's weight and power. Expect a new four-stroke from Kawasaki this year but not with this motor.

 

Very interesting. Thank you.
