Renthal off road front chainwheels are designed to offer excellent durability with a lightweight design which delivers maximum power transfer. Each sprocket is CNC machined from cased hardened and core refined 655M13 nickel chromium steel. Mud grooves are then CNC machined into each tooth on both sides to allow mud to flow away from the key contact points between the chain and the sprocket. This unique design helps reduce wear and dramatically increases the lifespan of your drivetrain.

With some of the biggest motocross names in the world, including Ryan Dungey, Eli Tomac, Jeffrey Herlings and Antonio Cairoli to name a few, Renthal are the number one source for providing world championship-winning sprockets to the world's fastest riders. The quality is undeniable, and the results speak for themselves; Renthal is far and above leading the way when it comes to sprocket technology and premium quality.

FEATURES

• To account for the extremely high tolerances required for engine components, Renthal make use of their in house CNC facilities to accurately machine each individual front chainwheel to the tightest tolerance possible.
• 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 655M13 Nickel-Chrome-Molybdenum alloy steel gives the ultimate combination of strength and hardness.
• Most off-road front chainwheels feature self-cleaning mud grooves between every tooth on both sides which help prevent dirt and mud build up (that traditionally leads to quicker wearing components). Available on UltraLight and Grooved front chainwheels.
• Certain models available in factory ultralight design to further reduce weight and maximise performance. 
• Renthal Ultralight™ sprockets are used by more factory motocross and supercross teams than any other sprocket in the world.
