    • Perfect fit

I put this 125cc engine on my 110 ssr. It fit perfectly. It came with all the wiring harnesses and carburetor. I did not use the one it came with. I used a 26 mm nibbi carb and installed an oil cooler. Its runs great and started up no problem.

    • Fired up 1st kick!
Color: 125CC 4-Stroke
Fired right up 1st kick! I installed on my 1975 Honda Z50. I did have to cut about 1.5" off the front fender for it to fit but it worked. Now beware because there are zero instructions. They sent me some BS wiring picture that made zero sense. You really just have to figure it out yourself. The wire they say is for lights blew the bulb in my headlight 3 times so I just have no headlight now. Way more power that the original 49cc engine and for the cost, it was cheaper/easier than rebuilding the original engine. Very quick shipping also. Id give 5 stars if there were a better explanation of how to wire it up. ... show more

Works very well on pitbike that I have, pretty powerful for a 4 stroke 125, I recently got the pit bike from a niebor who was just going to throw it away, the original engine I pulled out of it needs a top end, I wanted to start with a fresh engine. It is very responsive, these engines can be used in multiple applications as well, I have personal seen them on bicycles,quads,scooters/mopeds. They have multiple uses, I am very impressed with these little engines. I have used these in the past on multiple projects, when set up correctly,they are pretty reliable. ... show more

    • Started right up, definitely some rough edges, DOESNT TAKE 420 CHAIN!!
Color: 125CC 4-Stroke
It came almost a full week earlier than expected, the biggest issue I have is that I wish I knew what the mounting hole pattern on the bottom was and what size sprocket comes on it, you won't know until you get it, or maybe I'm just dumb idk. But after a wiring tutorial on youtube, which was very easy, this thing started up nearly instantly. I will warn you, there are 2 places the ecu can plug in, and it's not the one on the engine!! It runs great, sound great, had no damage, and I'm overall very pleased. WARNING, THIS IS BEFORE THE BREAK IN PERIOD AND BEFORE ANY RIDING ... show more
