Since this thread is about torque, I figured HP is in the same general realm......When I hit my 70s I decided to limit the hp of any cycle in my stable to 10 hp max. I figured much higher than that could be unsafe. This thing is rated at 5hp, so is well within my margin of safety. The easily removed 'training wheels' are of my manufacture and serve as a rolling display stand. Since it's a 2 stroke and both cylinders fire simultaneously, it requires two coils (or a dual fire coil from a 4 cylinder kawasaki ) which I have hidden below the crankcase. It runs nicely, but I have yet to ride it. My stepson is chomping at the bit, but I DO want to stay married so I'm sure you understand. The vertical single depicted in the ad is the 3 hp version, musta been their 'kid's model'
