.Piranha 90cc Semi-Auto Engine

Good engine, bolts right into an XR70R frame no problem.

Runs really good. Pulls wheelies with a 6ft 3in teen boy up hills, and the nine year old boy loves it.

First off this is1st time i ever felt like i needed to actually say somethin about something i bought online. This motor is hands down a bad mofo. Got a crapload of power for its size. Im 180lbs. This thing lifts up in2nd with my fat a## on there. By the way we swapped this into a xr50 2002 model. Bolt in and hooked up easy as you can get. Dont by lifan crap. BY PIRAHANNA! I got the stock carb on this thing rite now and it still rocks. Im buyin my 6 yr old more safty gear besides the helmet and he gonna tear it up. Kick ass website. Not a single bad thing to say and for sure comin back. Gotta get the pegs made for this set up for my boy anyway. Congrats t bolt, you got one of the most unsocial gearhead to actually write an actual review. Keep it up man.

Idid not think 90 cc can be so fast i got one on a atc 70 3 wheeler and i love it. I am going for the 140 next on my z 50 cant wait to see what that thing can do. Four thumbs up for piranha.

I can't express how easy this was to do, the motor was an exact fit, it actually went on easier than the old motor came off... the wiring was perfect, your customer service impeccable... I love to tinker with things but not typically vehicles, let alone motorcycles and after having talked with both of you I had a real level of comfort that not only could I do this but that if there was issue I had someone that new the product inside and out and would be willing to assist were they could... So my 10 yr old son and I decided to take it on... within an hour we had the old motor taken out and the new motor set in place... it probably took an additional hour to wrap up the rest, wiring, kill switch, chain, tire adjustments, oil change, etc... all in all this was a great project for my son and I... Once everything was done, literally one kick and the bike was running... we spent the rest of the weekend screwing around having fun ripping apart the yard... thanks again for all of your support... I can't tell you how important customer service is and how you both hit it right on the mark...
thanks for everything...
