Goes good so far been running it for about one weeks now, has good power compared to the stock 125cc, other than that it runs and goes great, was a direct swap from the stock 125cc no modifications needed

    • Great upgrade
Better guality... smoother run ing. Wire diagram a little challenging... takes 2 gas tanks of rum time to smooth out gear vox. Runs very good and stronger than a 125cc. 1 gear very low and taller gears 2 through 4th. Good value.
