I agree Firko about a splash of color being nice, I have 73 MX250, Tm250, CR250, 75 KX250, 74 Cheney BSA, almost the full spectrum.
Everyone has there own genius reason for what VMX bikes they buy and god forbid it should ever be logical or about investment. Hell I built the HL500 to gazump my mates TT500s, the RM370 because thats what Peter Ploen had when I was a boy flag marshaling at Whakatane, the RM500 because it reminded me of my PE175Z, see all very good reasons.
