We ordered this motor to do a rebuild for the second time me and my boys 3, and 5 years old but right away out of the box we had issues got the motor put together and tried to fire it up but we were not getting spark at all we tried everything even replaced the stator plate spark plug coil and ignition switch then last but not least the cdi and we finally got spark but it still wouldnt start and then i decided to use my old carburetor from a previous motor and two weeks after buying it we finally started the motor and took a drive yesterday afternoon now i will say we did purchase the premium 4 year protection plan but we decided to take the time ourselves and work this brain scratcher out ourselves but iam wanting to have my stator plate and carburetor replaced due to it belonging to my other project bike but this motor was garanteed to start with everything it was shipped with but all in all iam pretty impressed great motor excellent performance now i will say the first time my boys an i built this bike it was stolen from us twice in one week we got it back both times with our own hard work but this bike is a family hobby for me and my growing boys as we are all 3 of us new to the power sports world this being our first bike but second time we built it. ... 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.

  • 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

  • Great Engine
Size: 125CC 4-Stroke Motor Kit
The engine is well equipped and easy to install. There were some minor issues with starting, but the customer service was very patient and answered the questions in a timely manner. It has enough power and is very suitable for motorcycle.

  • Buen Motor
Size: 125CC Engine Motor
Este motor arrancó normalmente y funcionó de manera estable. Me impresionó profundamente el cambio suave y la función de marcha atrás sensible, que permitió que mi kart se condujera libremente. Ya sea una aventura familiar al aire libre de fin de semana o un evento competitivo con amigos, ¡puede manejarlo con facilidad! ... show more
