Renthal 315U52516P Ultralight Road 16T Front Sprocket (525 Pitch)

Renthal® Road/ Street Front Chainwheels are CNC machined from 655M13 nickel chromium steel, cased hardened and core refined for durability.

Typically available in Standard, Ultralight or Race Conversion pitches and a variety of tooth sizes where applicable. Race conversion sprockets are chosen by many factory teams across World Superbike and national superbike paddocks. A performance upgrade for your Street or trackday motorcycle.

Renthal 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.

CNC Machined
To account for the extremely high tolerances required for engine components, here at Renthal we make use of our in house CNC facilities to accurately machine each individual front chainwheel to the tightest tolerance possible.

Case Hardened
The case hardening process ensures that the front chainwheel has the longest service life possible. Each chainwheel is introduced to great heat that hardens the surface.

Core Refined
Core refined 655M13 Nickel-Chrome-Molybdenum alloy steel gives the ultimate combination of strength and hardness.

Ultralight
Certain models available in factory ultralight design to further reduce weight and maximise performance.
