Be careful. I had my share of 125 and 175 dirt bikes when I was younger and rode them like I stole them on the Mississippi River bluffs.
I have been thinking about one of those dual sport 600cc or bigger bikes to get back into motorcycle ownership. Figure they are something I can ride back and forth to work and still use to access remote fishing holes.
The eventual goal is to get rid of the Shadow and replace it with a Triumph Tiger 800XC, and augment that with something 250-400cc in a true dirt bike configuration.
I'm never going to sell that XR, I don't think. I'll never get my money back out of it and it's just too damned bulletproof to be worth selling. I may de-register and de-insure it, but then again, it's pocket change each year to do both of those things for it anyways. More expensive to give it a couple oil changes a year.
But, it's too big of a bike for where I went. If I had a 250cc with a granny first gear and fat knobbies I would have done a lot better than my Pirelli Scorpions and highway geared 600. I think a 400cc DRZ and the XR600 on a flatbed trailer behind my truck would make for a heck of a fun package to tow around and play in the mountains.
Next chain/sprocket change it's going down one tooth on the engine sprocket and up one tooth on the rear wheel sprocket.
ETA: I know for a fact the thing will do 92mph and has PLENTY of lungs left to go faster. I was terrified of the speed on that particular bike. Not nearly stable enough for that kind of speed. No problem losing top end down to 80-85mph and gaining a bit more low speed climbing stability.
