Transmission Gear Reduction Box Clutch 47cc 49cc 2-stroke Pocket Mini Bike T8F 11T 13T 14T 17T 20T Teeth Black

Perfect fit easy replacement, had the bike working again in no time. My friend’s son was overjoyed

replaced with no problems or issues.

I bought this because the original one literally tore itself apart. In three days. On this one, the pads were gone in two days. That's ok. The clutch works better without them. The springs are garbage, they are stronger than the original ones (which just discinegrated) but they won't stay connected to the gear. I opened it up and reconnected the springs twice before I took the springs and tossed em. It actually runs better without them. The rest of the transmission works fine, and the different sized sprockets that came with the assembly are nice, but I went with the original chain drive because my bike design requires an extension bar which the kit didn't have.So, with a little work, it will do the job

Wow boy I tell you what . this is a nice add-on to my mini bike. The bigger gears added a nice speed boost .

I received this and wanted to return it immediately just by looking at the flex drum you could see through it in some spots of the welding and air bubbles. Ended up moving and didn't have time to return it. I threw it on my bike today and it broke upon startup. Big waste of 40 bucks

This did not fit my grandsons 49cc SYX. However with a little modification to engine placement I did make it work

The clutch that was provided with the gearbox failed in less than 10 hour ride time (extremely generous). One spring cracked in half, keeping the clutch engaged, lead to an accident as my brakes couldn't compensate for the added power from the moror

Nothing it looks ruff and the clutch was wrong one
