SIP PREMIUM RACE CRANK  58 X 107 - GP

same webs as the SIP Race crankshafts but with the forged copper coated rod and silver plated bigend bearing same as the Tameni cranks rather than the beautiful billet rods as used in the race versions.This is a great crank for those who don't have a high horsepower motor,good for up to 22BHP with no problems,owners with significantly more than this should opt for a race crank
