I had intended to come over to Chiang Mai for 6 months and do some off-road exploring in Thailand/Laos/Cambodia. I've buggered the knee up and need some surgery which will keep me tarmac only riding for the first 3 months. A question for the tea sipping conglomerate A.K.A. GT-riders list: Can you have enough fun on the roads in northern Thailand on an XR 250 w/supermotard rim and tires and taller gearing? I can either buy a road machine (i.e.five12dude's TDM 850) and potter around on the pavement or get a plated XR 250 w/the motard rims and tires from Peter at Siam Superbike. The only tarmac roads i've done so far in CNX are up to Doi Inthanon, Doi Sutthep, and Samoeng. On a Baja 250 the only boring part for me was the slog out to Doi Inthanon, where a bigger bike would be better. So would Davids loops and trips be fun enough on a taller geared XR 250 w/17" motard rims and tires? Or do I commit to a larger streetbike?
