for Parts check out motosport.com.. oem and some aftermarket. tops ends stock last 40 hours easy. stock really is all you need on these machines unless your an A rider or more, and even then it is all you my need. the stock rod isnt the best, guys are putting in the pro x rod. check out ktmatvhq.com for some more information. if i had to chose between sx and xc i would get the sx and leave it stock over xc. the snappy rev power is sweet.
