    • Pops out of gear
Color: 125CC-4 Speed
The media could not be loaded. Pops out of gear quite frequent launches the Rpm’s up. Happens around 30-40mph guess I got one that has a faulty transmissim. Easy installation. Good throttle response. Great motor just the transmission problem sucks. Update as of June 17th, 2024. Engine still is responsive. Transmission is struggling bad to find 4th. Very difficult to put into neutral, when I had first got the bike it was 4 clicks down half click up for neutral. Then it went to only having to push it down all the way for it to be in neutral now it’s a 4 clicks down and a full click up to even find it sometimes it just goes straight to second. The transmission issues are very disappointing. Frequently still wants to pop out of gear at speed. - J UPDATE AGAIN. JUNE 18th, 2024. I AM FULLY DISSATISFIED with this product. Transmission no longer wants to be operated. Transmissions does not want to leave first when I upshift it goes into neutral. id like either a new motor or a full refund, when I buy a product it should atleast last me way longer than it has. ... show more

    • Everything's fine.
Color: 125CC-4 Speed
This engine seems to be a lot similar and I randomly picked this store to buy it from. There are some reviews but there are also bad ones so I was a little worried. But in fact the engine I received was fine, packaged properly, looks fine, starts fine, everything seems to be fine.

    • Great purchase!
Color: 125CC-4 Speed
The seller provided attentive help and took care of the assembly for us. It's been used now and the experience has been great, I think it should be very durable.
