Renthal Ultralight Front Sprocket 13T Honda CRF250R 18-21
Renthal front sprockets are simply the finest front chain-wheel on the market today. These countershaft sprockets feature a specially developed nickel-chrome-molybdenum steel which is case hardened and core refined to give the ultimate combination of strength and hardness.
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.
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.
