Our best information shows that the front tire size is 3.50-17 and the rear is 8.50-17 . The entire package is supported by the frame, Billet and tubular steel frame with CNC machined aluminum backbone and sub-chassis. We know you like to go fast or cruise all day, but when you need to stop, you'll be dependant on Double disc. ABS. 6 piston monobloc radial mount calipers front brakes and Single disc. ABS.
