High Performance Racing Spring for GY6 125cc 150cc 157QMJ 152QMI Engine Moped ATV Scooter Torque Spring with Clutch Springs (1500RPM)

I have them a gy6 169cc. They work great!

Working amazingly with the new performance clutch kit I purchased for my gy6 buggy. I wanted to keep usability and not keep the performance 2k springs but still wanted that little bit better performing clutch . Best of both worlds!! And topped it off with a new Kevlar belt. Works flawless

Perfect for 150cc gy6 don’t let that clutch explode trying to dissasemble it because it will be under pressure of your old spring also this a good balance between accel and top speed 1000rpm is too sensi and 2000 is too stiff highly recommend for built engine You will need to dissassemble the rear clutch u will need a adjustable wrench and vice to compress the clutch

Seems like a good quality product for a great price but not sure that it made a big performance difference

For this product, great as always. Purchased multiple times.

Mine was defective an broke would not fit correctly I tried to contact trkimal to send a replacement at least an nothing I will update this if they do the rite thing.

Exacto y preciso

No funcionó bien ahora mi moto se queda en primera velocidad siempre y rosa el clutch dando pequeños tirones hacia adelante

Keeps that high gear shifting smooth.
