Moturo alternator stator for Yamaha YZF R1 02-03
The Moturo stator for your Yamaha YZF R1 02-03 (RN9) - the component that comes to the bike when the windings have seen heat or the battery is no longer charging. 18 coils, suitable connection, ready to install.
The stator is located in the alternator cover on the left of the engine and uses the rotating pole wheel to generate on-board power for ignition, lighting and battery charging. 18 coils, matching connector for the R1 wiring harness.
A stator replacement is necessary as soon as the multimeter shows an interruption between the phases or the battery is empty after 50 kilometers - the most common reason why an R1 starts with a full battery and stops shortly afterwards.
Exchange in about an hour with a hexagon socket set, torque wrench and sealant for the housing cover.
