Upgrade your mini bike drive system with the DYC 420 Chain Set, precision-matched for popular 196/200/212cc machines. This kit pairs a 42-link front chain and a 90-link rear chain for ideal wheelbase reach and tension range on Coleman CT200U/CT200U-EX/BT200X, Baja Warrior MB200/MB165, Massimo, and Predator 212 builds. Both chains arrive pre-lubed and pre-run for smooth break-in, using hardened steel rollers and bushings for consistent engagement and reduced stretch. Four included master links let you fine-tune length or make on-trail repairs in minutes, while the compact chain breaker and adjuster simplify install, sizing, and routine maintenance. Whether you're restoring a stock setup or dialing in gearing for trails, the DYC 420 set delivers reliable power transfer, quiet operation, and long service life. Pitch 420 (1/2" x 1/4") fits common mini bike sprockets; please confirm your front/rear tooth count and axle position before final sizing. Built for weekend riders and daily commuters alike, this is the fast, fuss-free way to keep your mini bike running strong.
