  • Worth the money
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

  • Solid choice
If you're looking for a reliable and powerful upgrade for your bike, the 140cc 4-stroke engine kit is a solid choice. This engine delivers a great balance of power, efficiency, and durability, making it perfect for mini bikes, dirt bikes, and even custom builds.

  • 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.
