Moto-Master GP 420 Gold Drive Chain, 134 Links (642002)

The MOTO-MASTER GP 420 Gold Drive Chain, Part Number 642002, is specially engineered for motocross and professional racing applications. Designed for 2-stroke and 4-stroke race bikes up to 450cc and 70 horsepower, this lightweight chain delivers dependable power transmission and durability in demanding track conditions. Its gold brass-plated outer plates provide enhanced corrosion resistance while giving the chain a distinctive racing appearance.
The CRK pin coating uses hard-chromed pins to significantly extend service life, particularly in wet and muddy environments. Bushings and rollers are manufactured using specialized cold-forming technology that minimizes material deformation, helping maintain consistent performance under heavy loads. Precision pre-shaped bushings create an accurate fit between the bushings and pins, reducing friction and minimizing chain stretch during repeated racing use.
