Frequently Asked Questions

What does this part do on a motocross bike?

On the CR125/250, this rectifier converts AC voltage from the stator into DC voltage, primarily to power the RC valve (power valve) servo motor and sometimes a condenser or capacitor.

Will this fit my 2001 CR250R?

No, the 2001 model uses a different electrical system. This specific regulator is for the 2002-2007 CR250R generation.

Is it plug and play?

Yes, it features the correct 4-pin connector to plug directly into your factory wiring harness.

Note: Please verify your bike's model year carefully.
