Re: Bottom crank jack shaft.
big rig trucks also have very high gear ratios and many more gears than regular cars. they do not accelerate very fast at all. a ms200 is a very small semi, a big rig by no means. 210 hp is enough when you have gear ratios optimized for towing and lower speeds than regular cars. the 99cc predator does have more torque and less rpm, but the torque also means it has much more hp. a china girl has 2.5 hp at best, a 99 hf has about 4.5 after removing the governor.
some people say that a motorbike defeats the purpose of a bike. i tell them to get a flintstone's car.
