Default Re: Bottom crank jack shaft.

Sorry to spam your thread, but this guy really wants to make me look like a fool. Yank, your are 100% wrong anybody who knows Jack whack about mechanics and physics will agree with me. When you have say 2-1 reduction, it increases torque by 2 times and reduces rpm 2x. Agreed? So, that means you have the same HP. The engine in my bike has nowhere near the torque of a big diesel but more rpm, and still much less HP. I said that you could use two engines with the same HP, one more torque and one with more rpm, and have the same performance as long as they were geared correctly for each engine. Can someone else please comment on this, I know I'm right but this guy is persistent with his foolishness. Lol we both need to lighten up.
some people say that a motorbike defeats the purpose of a bike. i tell them to get a flintstone's car.
