Mega Moto 80; Good fitment
Well made for what it is, fits well, easy to install. Just needs lock washers on the hinge to keep it from vibrating loose.

Seat suspension
Very nice and easy to install on my Oryxearth. Much better ride combined with adding the front suspension fork as well. Springs are a little stiff but it works well. Went on some bumpy and uneven roads and it paid off big time. I definitely do not feel beat up after my rides any more.

Sad I wasted my time
It does at least fit the monster moto 80/105 frame. But that's about where the "pros" end.I don't know who those kit is designed for. I'm about 300lb, and even putting all my weight standing on one foot bouncing. The springs barely give at all. It might as well be rigid when it comes to who this bike is designed for (kids). So I ask, what's the point?The main "hinge" brackets are not only bent incorrect and crooked, but welded crooked as well. Mounted on the bike the seat is effectively corkscrewed from the frame.IF the springs were a proper spring rate, I could maybe overlook the other short comings. As is, I took it back off and put it back in the box.

It's ok
I'm gonna use this as the seat on my other bike. I'm 230 pounds and the springs are so stiff it dosnt absorb much of anything. Only thing is that you have to cut your seat up then if you don't like it you are screwed and have to buy a new seat.

Works
Had to lengthen the support for the front so it would actually clamp down, springs are super stiff
