Glixal ATKS-03904 High Performance Racing Moped ATV Scooter Torque Spring with Clutch Springs for GY6 125cc 150cc 157QMJ 152QMI Engine (1000RPM,Blue)

Better than the oem part on my scooter! I was able to reach 60mph no problem compared to before I would only hit 55-57mph and it’s tougher than the old spring it feels durable, looks great!, fits although you have to fight a bit to put new springs on if you know what your doing, gained more speed it functions well and great value for the money

Perfect fit. Works exactly as I expected.

Great product USA SCOOTERS

These springs do operate at their advertised rpm, BUT the clutch springs must be fitted. The clutch springs were about 3mm longer, total length, than the factory Rocketa springs. This allowed the clutch pads to partially engage the clutch drum at idle, causing the scooter to move forward at idle and also cut off when coming to a stop. You can squeeze the hook end of the springs together slightly with pliers and it reduces the overall length of the springs, thus fixing the issues. If the overall length of the 3 clutch springs doesn't match your factory ones, DO NOT install them until you modify them. Save yourself the headache.

todo salió como esperaba lo recomiendo

Nice spring set, does not feel like it increased pressure, probably needed to go to the next stiffness one. But works well

Me sirvió perfecto 150cc gy6

Perfect didn’t have the power to turn the red that came with the clutch.

Excelete👍

I used these springs in the clutch on my utv and they sure helped with acceleration like the get up and go part the beginning of take off. I used to have trouble spinning out from standing still now I can punch it and just about rooster tail it and to me that is a pretty big change since the old springs were probably worn out and old

Great upgrade for my little buggy

Yo tenía ya problemas de jaloneos al acelerar y con solo cambiar los resortes al clutch cambio a una aceleración mas suave y progresiva sin sacrificar potencia
