Stator for Triumph America, Bonneville T100 & Thruxton 900
Triumph America, Bonneville, T100, Speedmaster, Thruxton and Scrambler 900 cc - 2008 to 2017 - RMSTATOR part RM01387S
This is a brand new aftermarket stator supplied as a direct replacement for the original charging stator fitted to the 900 cc Triumph twins built between 2008 and 2017 - the America, the Bonneville and Bonneville T100, the Speedmaster, the Thruxton and the Scrambler. It is a plug-and-play part: it mounts in the original position inside the alternator cover and its three-pin plug mates with the standard loom, so there is no cutting, splicing or re-pinning to do.
The core uses the highest grade of lamination material and the windings the highest grade of copper, rated to resist 200 degrees Celsius. The long 1140 mm run from the grommet to the plug is made up as a complete harness, so the replacement follows the same route through the frame as the original. The connector and the rubber grommet are supplied with the unit, and every stator is tested before it is shipped.

Frequently Asked Questions
Does this stator need any modification to fit?
No. It is a direct replacement for the original unit on the 900 cc Triumph twins listed above. It mounts in the original position and the three-pin plug connects to the standard loom, so no cutting or splicing is needed.
What is included in the box?
The stator with its full 1140 mm harness, the connector and the rubber grommet.
How do I tell whether my old stator has failed?
Disconnect the three-pin plug and measure between each pair of the three black wires with a multimeter. All three readings should be about 0.4 ohms, within 20 per cent, and none of them should show continuity to the stator plate or the engine casing. A battery that goes flat on a ride, or one pair reading much higher than the other two, indicates a failed winding.
Will it fit an 865 cc Bonneville badged as a 900?
This part is listed by RMSTATOR for the 900 cc models from 2008 to 2017 and cross references to Triumph T1305502. The safest check is the number on the unit you are removing - if it reads T1305502, this stator is the correct replacement.
