http://www.vintagemx.us/cgi-bin/largephoto.cgi?C=ArtbeSsmRFC8yNKdI see a lot of these for sale and it drives me nuts. It's a RM125B with a bondo-ed tank, painted in the Moto-X Fox colors.
Sell it as a 1977 RM125 (My favorite bike in the world!) with a Moto-X Fox tank, but it is not a Moto-X Fox RM125B Replica. The shocks might be 17.5, but the ad doesn't say. No Thor swingarm, Fox head, Fox pipe, Fox silencer, white side-panels, Sun rims, Mototek ignition, Simons forks or Tony D fender.
We each put our personal touches on our bikes and to each his own, but why misrepresent your bike when selling it?
