The RK MXU UW-ring Gold 520 chain is known for its exceptionally strong and narrow build with the highest tensile strength in the market. A top choice in MXGP and FIM Hard Enduro championships, it shares the sealing solution commonly used in the Moto3™ category of MotoGP™, offering 5% less friction for increased range and performance. Optimized rubber rings reduce vibration and plate friction, while the rear sprocket, machined from 7075 T6 aluminium, ensures the highest possible wear resistance. The front sprocket, forged from hardened steel, boasts an equally long lifespan.
The Stark VARG chain tensioner features a special and unique design. Instead of the traditional screw-and-bolt system Stark have implemented an aluminium plate, stainless steel grooved bolt and clicker mechanism. With a torque T25 tool the rider simply tightens and count the clicks and applies the same measurement to both sides of the swingarm. There is no need to look for marks or constantly realign. A much easier process.
