That guy mboddy, he's weird. Who'd ride a TDR at a dirt track race? But I have ridden with him round Wakefield and that thing is seriously quick, and must be more so now with all the mods. And Mark is a good rider too, how he can get the corner speed he carries with that thing is anyone's guess...
As for my one and only, Geez. Too hard.
To race 'vintage', probably a Pre 85 Honda CR. I am not a Honda fan, but those things seem to be pretty good. Otherwise a YZ250G. This is being practical of course. If I could have any 'old' bike, I'm with asasin, I love the looks of Howerton's Suzuki.
Mind you, if I didn't want to race and just need an old dirtbike to haul out and look at and go for a ride, I'll have my 79 TT500F back please.
