This is an italian made anodized aluminum motor mount clamp. To determine what size clamp a particular chassis needs, please measure with a caliper using this procedure: First, measure frame rail diameter (usually 30mm or 32mm). Spread Measurement: measure total distance outside to outside where the motor will go and subtract the rail diameter from this number. (Example: 122-30=92mm center to center).
Clamps are priced individually.
Tips: CRG has a 90mm spacing. Almost all other Italian made karts like Birel, Topkart, Intrepid, PCR, Tonykart, etc. have a 92mm spacing.
