§ 02 / About this part
What it is
The PARTS EUROPE STARTER YA, motocross part. Stocked by Iron Offroad, the UK MX hard parts specialist.
Designed to replace OEM 5TJ-81890-00-00, this starter motor is a direct fit for your Yamaha. It resides on the engine block and is the heart of the electric start system. Wear and tear on the internal commutator often leads to intermittent starting issues. This unit provides a reliable solution for riders who have moved away from the kickstarter. Ensure the electrical lead is routed away from the exhaust header during installation to prevent heat damage to the wiring.
