These flywheel weights will fit GG Pro 250/280/300cc model with the HIDRIA ignition.
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. They come with a ignition cover spacer, gasket and longer ignition cover bolts.

Quick installation. Don’t need to remove the flywheel
This was a very easy install and quality is very good. It really helps tame down my 280 as well.
Service was as good as it gets. Was at my door in 3 days!
