I'm looking into one of these bikes that has been plated to do some hard offroad riding. I've got some concerns and questions. Any feedback will be greatly appreciated. Is this a high maintenance bike? How many miles between oil changes in dualsport like conditions? Can it handle alot of miles without a rebuild or trouble? Hows the reliability? Whats different than the popular 450? Can the stock suspension handle a 175 lb. rider on some nice jumps? Any flaws from the factory to look out for? what's a fair price for a low milage(under 1000) 02 model? I know that's alot of questions but I didn't turn up much on the 426 when I searched it.
