Advanced Cooling Upgrade for Honda, Suzuki & Yamaha
Upgrade your charging system with our premium 4Drive MOSFET Regulator Rectifier. Unlike traditional SCR/Diode style regulators that generate excessive heat, this MOSFET unit operates significantly cooler and more efficiently. Engineered specifically for ATVs and Motorcycles from 1997 to 2020, it features integrated overheat protection—if the unit reaches critical temperatures, it momentarily disengages to cool down rather than burning out, protecting your entire electrical system.
RELIABILITY: Designed to outperform OEM specifications with superior heat dissipation and stable voltage output across the RPM range.

Questions & Answers
Is this a genuine original part?
This is a premium quality 4Drive aftermarket replacement part. It uses MOSFET technology which is an upgrade over the original equipment (OE) diode-style units for better reliability.
How do I know if it is compatible?
Compare the connector pins and mounting hole spacing (80mm) to your original unit. If your part number is listed in the cross-reference table above, it is a guaranteed fit.
Can I use this with a Lithium-Ion battery?
This unit is optimized for standard Lead-Acid and AGM batteries. Unless specified otherwise by your battery manufacturer, we do not recommend using this specific model with Lithium-Ion batteries due to different charging voltage requirements.
Note: Please visit 4drive.co.uk for further technical support or fitment assistance. Always verify your original part number before purchase.
