question on the new yz250f for you engine guys
Posted July 03, 2000 - 11:03 AM
My questions is in the past what type of engine power is most closely related to a large bore and a short stroke with high rpm's. Is this going to give more torque or HP than ussual. What other characteristics do you see coming from this engine?

My question I belive has been answered. This is going to be a high HP low torque engine for a 4 stroke. Maybe we should call it a 3 stroke. A compromise between the two

because an engine is a short stroke, doesn't mean it won't have a good spread of power.
possibly a four valver would be better, but if you remember the fzr's came out in 1985. so i'll back Yamaha.
have you ever smiled at the fact that we use a single exit exhaust, or that the brake lines take a different route.
fudging design, marketing & patents have more to do with all this than the last one BHP.
if the world superbikes produce 150BHP at the rear wheel that means each 500cc cylinder is producing 73BHP. the WR/YZ's are producing 40-45!
