saxonator, for most of the offroad riding you do, im not sure. i predominantly ride mine on the road. Having said that, on the odd occasion when i do do a dirt link up the bike handles it fine, its a nice mellow power for the dirt and it doesnt feel that heavy, having said that i havent dropped it yet! wont be long though!
maintenance so i am told, is pretty easy, i change the oil every 1500kms but that is probably overkill, ive heard 6000kms is a more realisitic figure.
i think parts are actually quite expensive and would probably have to be sourced from singapore if its a major part.
i know pee on the board rides his more offroad than i do, maybe a little pm to him may get more comprehensive answers...
cheers
