Performance Regulator Rectifier For Hyosung GV GT 125 250 R GTR

#1 Electrical Problem on a Hyosung?  The Regulator Rectifier !  (so they say..)  …Read on!

🔲 Standard Regulator Feedbacks

  • Poor Charging / Unstable Idle / Erractic Electrical Behavior
  • Burns holes when it dies  (🔻 see video below….)
  • Poor Lights  /  Sometimes the Reg Rec upsets the Stator (Generator inside engine)
  • Lifespan issues  (old diode tech) / runs too hot 
  • Costs £80-120 from Factory (& more so for “EFI” bikes)

⚡️ Performance version:

(Better Cooled & Larger Heatsink used)
 ✔ From large CC Kwaks
(Beefier than ALL Hyosung regulators.)
(uses the same plugs & more importantly correct wire positions / polarity!)
(Smoother revs through gears)
(plus faster cold starts!)
(An improvement on some models of Naked bikes & Cruisers)
(More battery juice than a stock unit!)
(Less load in your Stator/Generator)

📽 Customer Running Video Clips
