[QUOTE="DualSportr, post: 156168, member: 19592"] torque, as measured by a hydraulic dyno, is the amount of force the engine can "push" against the load (which is generated by the dyno) at specific rpm's. Horsepower, as measured by a drum style dyno, is the amount of time it takes to get to a given rpm. If you put a two stroke on a torque measuring dyno, it will not "hold the load" at lower rpms - which means it is not generating torque. It will start to "hold the load" at higher rpms - which shows the bike is able to generate power in this range. Call it whatever you want - but an engine which generates lots of "push" at low rpms will create what the general public would construe at "torque", and an engine which generates no "push" at low rpms, but is able to create power at higher rpm's in a quick manner is considered to have lots of "horsepower". It's a given that all engines generate some torque and some horsepower - it's just the percentages that change. Admittedly, two strokes do generate torque, since it's all power per burn cycle, but they are more efficient at generating power at higher engine speeds. Four strokes are typically more efficient at generating power at lower engine speeds. [/QUOTE]
