I have an xr50 with an 88 kit on it. Big Mukuni carb, aftermarket pipe, tall seat, big bars, big pegs. I am pretty sure the spring is aftermarket
It pulls a 220lb, 6'2 adult without issue. Wheelies VERY easily. 3 gears. Not for a child unless you've got a skilled kid ready for a lot of power. No trades thanks.
It's a 2003 from Nevada so no paperwork as prior owner said in 03 they didn't require any.
$950 for barfers, % to barf.
