Looks like a real piece of shit to me. 125cc four stroke streetbike? Man, that thing wouldn't be able to get out of it's own way with a motor like that. I could maybe see this being good for a kid that would normally have like a piece of shit moped.
"For those that want to get tons of performance out of this get the 140 big bore kit, cause not only are you upping the displacement but you are increasing the compression ratio and will gain about 30% more horsepower and can probably go up 2 teeth on the front sprocket and get this thing going around 75mph."............... WHOA!!!
