Description
If you’re running a 428 chain setup on your off-road bike, sprocket weight directly impacts acceleration and overall handling—and this Renthal ultralight saves you nearly two-thirds the mass of steel without sacrificing durability. The CNC-machined mud grooves keep debris from packing up, maintaining consistent power delivery through the gnarliest terrain. Built from 7075-T6 aluminum and finished in a corrosion-resistant orange coat, this is a bolt-on upgrade that delivers real performance gains.
