Huge difference between the first 2 and the last.... The lei XR will sell for under $400 and the MSO will prob sell for closer to $600.
MSO is a better bike, just depends what u want to spend.
I have the lei xy-s 125cc..... cost me $425
The lei xy-s has a shitty frame compared to the MSO.... but for motard it doesnt matter to much as u arent really subjecting it to much strain (jumps etc...)
It was a bit of a pain in the ass to get wheels to fit but if ur handy with tools it shouldnt be a problem.......
so yeah, if u want to spend the loot get the MSO but the lei xr will do the job.. albeit with less style and more piss farting around....
btw... expect them all to fall apart after every ride lol
