For people who like to talk about torque instead of HP I would like to say that if you remove one spark plug wire and run engine on one cylinder torgue will be the same as with 2 cylinders.
it should help to understand that torque means nothing.
Power (hp)=torque(lbf.ft) x 2Pi x RPM/33000=Torque x RPM/5255
Horsepower is what i consider to mean nothing. Horsepower basically is nothing but work performed over time. Take a 1cc engine producing .0001 f/lb torque and spin it to 10,000,000rpm and it will produce the same hp as a 10,000cc engine producing 1000f/lbs of torque at 1 rpm. The 1cc engine wouldnt be able to move anything beyond its own weight without REDICULOUS gearing.. while the 10,000cc will haul nearly anything without noticing... but VERY VERY slowly.

2 engines with same HP will move anything the same.
Formula HP=Torque x RPM/5252 is a high school knowledge. I was studying that when I was 13. You just need to read text book for high school to understand that.
Old farts like me usually don't remember physics.
If you stick 5 feet long rod in rear wheel and try to spin wheel with force of 20 lb. you will create 100 lb.ft torque (20 x 5). How fast will you move your bike considering 100 is pretty good torque?
Get physics text book, guys.
