Stroker Cards
Description: Powroll Performance was founded in 1964 by dirt bike enthusiast Paul Olmstead in Bend, Oregon. Little did he know that the side business he started in a cinder block building behind his house would go on to become one of the longest-running performance companies in the motorcycle industry. Paul devised a way to shorten OEM connecting rods, creating a simple and less expensive way to build stroker cranks for OHC four-stroke engines. Powroll's stroker cranks made great power while increasing reliability and did so at a reasonable price with little to no additional modifications, making them wildly popular. Cranks were Powroll's primary product, but they built up a pretty extensive catalog of performance parts over the years.
