After seeing scotto's 212cc predator, ive decided im going to build one also, upgraded hub and stronger spokes def needed along with disk brakes, jack shaft and cvt, i hope to cruise at 45-50 mph, top speed 70 mph, frame will be heavily braced, just need to gather up the parts, and get to welding, is there a tire that can handle those speeds, itd be nasty to blow a tire at those speeds
