I rode my mates 2014 KTM 250sx on rough trails and the front end sucked. The closed chamber WP fork deflected in the slower stuff and I was fighting the bike just the stay straight and upright. In comparison, the revalved KYB open chambers on my 310 ruled in slow tech AND fast rough. My Sherco's WP open chambers (resprung, stock valving) work really well too but perhaps not as magical as the tuned KYB's. I rode all three on the same trail, same day. I'm very content with my bike choices
