  • Best motor there is!

    I have bought 2 of these and now ordering #3. The entire kit is high quality, and the new motor has more torque and power than any 80cc out there. I broke them in gently and slowly and the payback is like riding my Husquavarna CR125!. Lots of low und grunt, it pulls up any hill at any speed with a 36tooth rear sprocket, and with a banana pipe and a little tuning hit 47mph after break in! You simply cannot find a better motor, better put together kit, anywhere and you cannot beat the price! 1 very happy camper here!

    This motor is extremely powerful right out the box. Can't wait to see how much quicker it can get once I break it in.

    Easy to install with instructions on the internet. Went together well with the exception of a missing piece to connect the clutch cable to the clutch level. With the parts that I did have it was easy to improvise and it runs fine so far. I am a 185lb adult and it pulls me around fine and on hills pretty well with the 44 tooth sprocket.
