This Brand New MOSFET KTM 450 Rally Factory Replica Voltage Regulator Rectifier (year: 2017). This new unit runs cooler than all OEM diode style regulators. Additionally, the rectifier has an overheat protection function that will turn off the rectifier for a while allowing it to cool rather than let heat up. This voltage rr is a direct replacement to your original unit, is plug-and-play and a direct fit, making this an easy installation for you. The quality of this unit exceeds the OEM equipment because it is made with a higher grade of electric components. 

* All items shipped are tested. 

* Battery condition is very important! always start with a fully charged battery before performing any tests or replacing any parts. 

Why use MOSFET Tech? 
- This newer technology runs much cooler than traditional shunt voltage rr's. 
- It saves gas creating a lesser load on the stator which means less work, causing less fuel to be used. 
- The life and cold-cranking capacity of the battery is also extended. 
- More engine power relieves even more load on the stator resulting in more power. 
- This technology also regulated the energy power charging the battery for a steadier and smoother performance.
