Designed for motocross/competition use, this kit prioritizes reducing friction and abrasion resistance on demanding terrains.

Its gold finish adds an aesthetic touch to bikes that want a race look.
Common compatibility: KTM 125 SX (1995–1997) and other motocross machines accepting the 520 pitch. Check the number of links and the front sprocket for proper installation.
