AFAM, 520MR2 14/50 Standard Chain Kit - Ultra-Light Sprocket for 1999–2003 KTM EXC 250

AFAM offers a 520-pitch chain kit for the KTM 250 EXC 250cc, KTM 250 EXC SIX DAYS 250cc, combining a standard MR2 chain without seals, a 14-tooth steel sprocket, and a 50-tooth Ultra-Light aluminum rear sprocket. The chain’s chrome-plated pins and forged rollers contribute to its durability and smooth operation under continuous stress. The aluminum sprocket reduces the weight of the rear drivetrain compared to a conventional steel sprocket, which minimizes rotating mass and promotes a more responsive ride. The steel sprocket ensures precise engagement with the chain and effectively withstands the forces transmitted by the engine. Replacing the main components simultaneously ensures a uniform drivetrain and minimizes uneven wear. This kit thus offers a balanced compromise between light weight, reliability, and riding enjoyment for compatible motorcycles.
