§ 02 / About this part
What it is
The RENTHAL SPROCKET R 525 45T HA, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
This part mounts to the hub to complete your final drive. CNC machined from high-strength aluminium, it reduces unsprung weight for better suspension response. Hard-anodised surfacing increases service life against chain rollers. Mud grooves are machined into the tooth base to shed debris on heavy MX or enduro days. Replace when the teeth show visible thinning or when fitting a new chain. Always use new bolts and torque them to factory spec in a star pattern. This fitment matches the original bolt circle diameter for a seamless swap.
