Bore Measurement
Bore refers to the diameter of the cylinder, in which fuel is burned in a series of rapid explosions to drive a piston. The larger the bore and stroke numbers, the larger and more powerful the engine, and the more horsepower it can develop.
Bore/Stroke Ratio
The bore/stroke ratio is the number reached by dividing the bore by the stroke. This ratio gives motorcycles their engine characteristic. The higher the proportion of bore to stroke, the more horsepower an engine can develop. The average ratio in motorcycle engines is about 1.2.
An engine with a ratio of 1 is said to be square in design, while a ratio greater than one is oversquare and less than one is undersquare or long stroke.
Ratio and Performance
A bore/stroke ratio of 1 or more means the motorcycle is operated at higher RPMs. The lower the ratio, the more turning power is given to the drive train, allowing the bike to maintain power on hills. Long stroke measurements, however, generally mean higher engine friction, shorter fuel mileage, high operating temperatures and higher maintenance.
