Watch out for some of the Chinese bikes. They are made of stale cheese. Even the SDG's are falling apart.
I have an XR50 that has really taken a beating. I have bent up some parts but that is my fault. I am more of an icy hot stunter on it and that causes me to crash a lot.
Upgrades are coming soon. Fluid filled front forks. 88cc motor. New frame and swingarm.
I already have aquired two complete sets of rims for it so I can do a 10 minute swapout from dirt to street or vice versa.
With street tires on it. I still need a black seat cover. Yes, I cut the front fender short like a supermoto.
