Renthal Ultralight Front Sprocket Kawasaki/Yam KX/YZ250 99-23, YZF/WRF 450 99-23\nRenthal front chain-wheels are simply the finest front chain-wheel on the market today. Our Front chain-wheels feature a specially developed nickel-chrome-molybdenum steel which is case hardened and core refined to give the ultimate combination of strength and hardness. ULTRALIGHT chain wheels, Renthal have taken extra time to machine away surplus mass to reduce the mass of the chain-wheel. Chain-wheel mass reduction offers a two-fold gain. The overall mass of the machine is slightly reduced and the rotating mass of the gearbox is reduced, allowing faster engine spin-up and shorter over-run. GROOVED chain-wheels have cut outs at the bottom of the tooth to allow the escape of mud that would otherwise be trapped between the chain-wheel and the chain. Allowing the easy escape of the mud prevents tension being placed on the chain and the resulting accelerated wear. FITMENT: KAWASAKIKX250 99-08 YAMAHAYZ250 9y
