Well I'm seriously thinking about that XR500 in my garage mate, I rode my BMW R100RS up into the mountains today, and on my way down again, I was being pretty careful negotiating corners signposted as low as 10 MPH, when from behind me a massive BRAAAT exploded beside me and a young guy on a big 4 stroke dirt bike or "Super Retard" exploded past me.
I almost crapped my pants. I'd already had one near miss when I rounded a corner to find a wanker in a SUV driving at me on my side of the road mid-bend, but the noise this thing made as the rider roared past was like a gun going off. Sweet! With the BMW, the riding position is "head down and butt up", so I was envious of this guy sitting up straight and throwing his bike around those tight bends like they were nothing.
The XR500 in my garage is fitted with knobby tires but they're old and worn out, so I think I'd install some "dual purpose" tires, if I can find one for that 23" front wheel. Of course all this might be wishful thinking if Ken, the owner, doesn't want to sell it, but he's a bit of a "wheeler and dealer" and he told me that he wants to buy a Ducati Mike Hailwood Replica the other day, so this might help him get closer to some Italian mechanical porn.
