🛵 Glixal ATKS-03903 High Performance Racing Torque Spring for Chinese Scooter GY6 50cc-100cc 139QMB Engine Moped ATV (Red, 2000RPM) Review

Seems a little stiffer than at 1500rpm but worked and the paint came off fairly quickly which is normal but I ended up going back to a lighter stock.

For the price and fast shipping response you can't find it anywhere else. These springs, when used properly, perform the same as the "high performance" parts of the more expensive brands.

Could not stand, what the logistics gave! Peeling paint, looks slightly bent. Can't tell how it works as it's too corrupt to even try.

Good quality lock and clutch springs. They fit and work, nothing more to check. I've had them for about 500 miles, overfilled, and they still work as good as new. I don't know other people's results since I started with a new clutch, but these springs made them engage at around 3500 rpm. Good quality.

A very effective product for customizing your scooter drivetrain, but I am afraid there is no one size fits all. A bit of experimentation almost always requires a combination of springs to get it right as every bike is unique.

The product was in good condition and everything in the picture. I installed BBK and added 6-1/2 pulley weights. I then rode the scooter and it was fast with good mid to high grip. I wanted to improve performance so I got this 1500rpm spring. I installed it, tested it and lost performance when switching. You'd have to turn a lot more before it all moved, and all top speeds were the same. When the engine and transmission are heavily loaded, the engine temperature has risen sharply due to more…
