These flywheel weights will fit any GG Pro 125cc/200cc/225cc model from “2002 to 2014 (will not fit 2015 models).

They change the power delivery making the bike smoother and more controlable ‘off the bottom’. They will help the bike grip better and help stalling…work VERY well on both models…. shrink fit, needing to be heated to fit onto flywheel. Three ‘tacks’ of weld are advisable when in position. Make sure the spark plug cap is pulled off before welding so not to damage the ignition.
There is also a lighter flywheel weight available for the 125 from 2015 onwards with the 3 screw fixing.

The flywheel weight kit comes with:

1 x flywheel weight
5 x Bolts
2 x Gaskets
1 x S3 casing spacer
