Amazing Motor
Color: 125cc Engine,Electric Start
I replaced the motor in my 125cc quad and it fit and worked perfectly. The wiring is difficult but I have a lot of experience with that kind of stuff so it wasn't a big deal. I would definitely buy this motor again, although i wish they provided more product details.

Great motor!!!!
Color: 125cc Engine,Electric Start
This is the best 3 speed 125cc motor I’ve owned! The brand name BounceyCart definitely fits the motor! Highly recommend! Easy install 2 hours including taking out the old motor. I think I could have finished this in 1 hour in a garage or better area. *Notes* using old engine harness. It’s easy don’t worry. 1) Cut the old plug connectors from your old motor rewire to new motor*. Most 125s only need to cut one plug I had to cut both. 2) yellow and white cables go together (White to yellow and yellow to yellow) yes you can switch the yellows to white and it will still work has no set way. ... show more

Bad wiring / electronics.
Color: 125cc Engine,Electric Start
The motor is perfect but the wiring and electronics are not good. I bought this motor for a taotao atv. Installed it, hooked up the harness and electronics, and had no spark. I troubleshooted everything I could and ended up dissecting the wiring harness to isolate only the parts needed to make spark. After all this trouble I found that the cdi was bad. I ordered another cdi and coil, installed it and now it runs great. Just know if you buy this motor, you need to be good with electrical systems. ... show more

Seized engine
Color: 125cc Engine,Electric Start
Motor over heated and seized the first day I took it for a ride. But I'm getting contact with their team. Been helpful so far.

No plug and play here
Color: 125cc Engine,Electric Start
It's not plug and play it involves dissecting the wiring to get it going so like it says you'll have to be a professional to get it installed correctly
