I am in the market for a new KTM 2 stroke and can't decide between the two. I will be racing 10-20 hare scrambles/cross country events including GNCC events next year. I have narrowed down the bike search to a 2011 or 2012 250XC or 250SX. I already understand the differences between 2011 and 2012 so there is no need to list that. My question is, is it worth the extra money for an XC? I want an XC but for $800-$1,000 more, you can do many modifications to convert the SX to a woods racer. The one thing you can't do, is change the gearbox. I likely would put a larger tank on both bikes, so that is equal, 18in wheel isn't that big of deal to me. What else? I just can't justify the difference in price. Am I missing something?
