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

Good

Great product USA SCOOTERS

I know people typically go the heavier springs but I have a commuter scooter with a somewhat unique GY6 1P63QMK with a lower powerband than a typical scooter. Before it seemed to drag from a dead stop. With these it launches with no hesitation. And I didn’t lose anything off the top end. 4 stars because the clutch springs were painted shut and I had to bend them to crack the paint between the coils before installing. Other than that, solid buy.

I got these springs for my 125cc scooter because i installed an aftermarket exhaust. Works as i expected, great product.

does the job

These didn’t change my rear shifting - I’d say they’re about stock tensions. Solid product.

ok

Just used the large spring and made a good diffrrence
