    • Easy to install fired right up
Size: 125CC 4-Stroke Motor Kit
Replaced the motor on my daughter’s Apollo 125. Was easy to install, had to splice some wires (simple nothing too complicated) and it started on the first kick. Definitely recommend if you’re in the market for a new motor. Edit**it did have the option of electric start. Not something we needed but cool to see. Also, we had to put the old carb back on, because whatever this one came with com the motor was getting too much air, and it was idling incredibly high. Swapped them out and it purrs like a kitten. ... show more

    • Not a bad replacement
Size: 125CC 4-Stroke Motor Kit
The clutch was sticky at first, until you get it going and shifting through th gears, then it’s works fine. Been having an issue with the kickstarter though, it goes into like a neutral for a few kicks, then gabs and fires rights up first kick (not grinding noise) Kind of weird.

    • Works great
Size: 125CC 4-Stroke Motor Kit
Blew the motor on my SSR and bought this as a replacement. Easy to switch the motors out. The one problem I had was I couldn’t get the motor to idle right with the carb they provided. I hooked up the old carb and it was all good to Go.
