Fitment FAQ
Will this part fit my specific model and year?
This regulator is designed for select BMW S1000RR, S1000R, S1000XR, HP4, C600 Sport, C650GT, and C650 Sport models. Fitment can vary by production date and submodel, so use the compatibility table together with your OEM number, connector configuration, dimensions, and product photos before ordering.
Do I need to match the OEM part number?
Yes. Matching BMW OEM 12317718422 (12 31 7 718 422) is one of the best ways to confirm compatibility. You should also verify the 5-wire configuration, 70 mm mounting-hole distance, housing shape, and connectors because model name alone is not sufficient for fitment confirmation.
What models or situations does this part not fit?
Do not order this regulator for motorcycles using a different OEM number, wiring configuration, connector shape, mounting-hole spacing, or housing dimensions. Later generations of the same BMW model may use a different charging-system design even when the model name is unchanged.
What should I check before ordering?
Check your model and year, OEM number, connector shape, wire configuration, mounting-hole distance, housing dimensions, and original part appearance. This replacement measures approximately 90 × 84 mm with 70 mm mounting-hole spacing. If you are unsure, send us your model, year, and a clear photo of the original regulator for fitment assistance.
Indian Scout rectifier died over the easter bank holiday, found this on amazon next day delivery and is identical, put it on the bike and is charging at 14.1v across the whole rpm range, got back from the test ride and the rectifier wasn't hot so this really saved me. We'll wait and see how long it lasts
Worked perfectly for an older cafe build. I didn't want to pay $400 for an oem so I snagged this, wired a plug and presto, charging system working again.
I bought this rectifier to replace the failing one on my motorcycle. The unit is made of solid metal and plastic, which feels sturdy and looks like it will resist the weather well. It was very simple to fit into the space using the original mounting holes. The size matched the old part perfectly. I checked the voltage after installation and it provides a stable charging voltage to the battery, which solved my electrical problems. The connections were straightforward to hook up. This part is a reliable and much more affordable alternative to buying the official factory unit. My bike now runs much better with a steady electrical system.
