§ 02 / About this part
What it is
The Moose Offroad REAR SPROCKET / 45 TEETH / 520 PITCH / BLUE / ALUMINUM, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.
Unsprung weight at the rear hub dictates how your suspension reacts to high-speed chatter. This aluminum sprocket significantly reduces mass compared to standard steel units. It is designed for racing and hard enduro where every gram matters. Replace this part when teeth show signs of hooking or side-wear to maintain drive efficiency. Always fit a new chain and countershaft sprocket at the same time to prevent accelerated wear on the aluminum teeth. Use fresh sprocket bolts and high-strength thread lock for the install. Check your chain slack after the first heat to account for initial seating.

§ 05 / About Iron Offroad
Iron Offroad
Iron Offroad is the off-road sibling of Iron City and Iron stable — this is a UK shop for motocross, enduro, and trail-bike hard parts. All fitments live on the site, and listed against MX models KTM, Husqvarna, GasGas, Yamaha, Honda, Kawasaki, Suzuki, and Beta. Pick your bike on the timing-tower. Our USP is in the data, fully enriched to assist with accurate fitting and finding the right part for your bike quickly and easily. Brands you'd find on a paddock workbench; pads, sprockets, plastics, fork seals, cables, gaskets, bars, the things that actually wear out. Road-bike kit, scooter parts, and quad gear sit elsewhere. Dirt & e-moto only. We operate from our huge storage facility in Leeds. Iron Offroad is a trading name of Iron Stable Ltd, registered in Mildenhall — Company No. 17061294. We have a RICH motorcycle history with multiple moto brands the images showing where we came from and our history, the business recently pivoted into hard parts and online retail.
