These flywheel weights will fit any GG Pro 125cc model from 2015 onwards
They change the power delivery making the bike smoother and more controllable ‘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 a heavier flywheel weight available for the 200cc/225cc.
