    This is the 2nd project that I've built. Although I haven't even come close to breaking this engine in, I'm impressed with how smooth this engine runs. It is a step up from my first kit which was a rather unbalanced and power anemic old school China Doll.

  • This motor hauls some serious ass!!

    I'm back to order another one of these. I sold my other one for $600 as it was the fastest, and most reliable kit I have ever seen, let alone bought. I have built over 28 bikes and been through all the crap for sale on the internet. This kit is EASILY worth double the price as all the parts and engine are top quality and they all work even better than expected. I never review anything, yet also never have been so satisfied with anything I have bought sight unseen but I'm telling you, try out one of these and you can thank me later, and you will, I promise!

  • 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.
