Glixal High Performance GY6 150cc 180cc 200cc Racing Final Drive Gear Set 152QMI 157QMJ 161QMK 161QML Scooter Moped ATV Go Kart (15T/37T)

I've had a set of these gears in my transmission for about 3000+ miles now with no problems. I got the 20% taller ratio over stock and it was just a tad too much. The engine seemed to bog down quite a bit and had trouble getting the revs up where my A8 cam and ported and polished head could get it's legs under it. When it did, OMFG! I got a GPS confirmed 71mph out of a 155cc gy6 scooter/rocket ship.The only problem is that while these gears improved the fuel mileage tremendously on the highway (2 lane Arkansas back roads) in town the bogging and cam and huge cam would suck a tank of no-ethanol premium dry at a stunning rate.My axle bearings have had it so I'm replacing the whole rear-ended gear set, bearings, shafts and seals. Might as well. They are relatively cheap and since I'm in there anyway I figure, WTH, why not. I'm expecting these to sort out my bogging issue and since I'll be able to push it to redline possibly a little faster too.

Like basic. Works fine

I installed these gears in a Tomberlin crossfire 150R go kart . The engine is a GY6 150cc bored out to a 155cc with 28mm carb and a custom built exhaust pipe to make this engine breathe. The gears were 14t by 38t. Which is about 17percent more speed. This gear selection will give you a few more miles an hour with out killing your hill climbing ability. I am very happy with this selection. At times scary fast.

I probably picked the wrong set of gears but I lost everything, went back to stock gears, back up to 55 mph

I haven’t got to test these gears out quite yet. I will update this review once I do but these do look like solid gears press mine together and I actually bought three different sets. I’m gonna be trying out different sets with this new GY6, 232 cc I just built Will be updating

Built gy6 buggy and this fixed going to slow

It was a perfect fit

The gear sizes aren't even the same. Kymco agility 125 is 16-47 teeth. on a 2021 model. i'm dissapointed because in the description they said Kymco. So for people who have my bike, don't get these because they just aren't compatible.
