§ 02 / About this part

What it is

The MOTO-MASTER SPROCKET ALU BK 420-45T SX65, sprockets. Stocked by Iron Offroad, the UK MX hard parts specialist.

This lightweight part is specific to the drive train found on 65cc junior bikes. It reduces rotating mass at the rear hub for better throttle response. Replace the component when teeth begin to hook or wear thin. This fitment is tailored for junior racing platforms. Adjusting the tooth count helps your rider manage power delivery on different track surfaces. Ensure the chain is correctly aligned during installation. Use fresh locking nuts when mounting to the hub. It matches OEM specifications for a precise fit on your bike.

§ 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.
