I have an Alpinestars bionic jacket without the elbow protection that has about the same level of coverage. I always wore it when riding minis at my buddy's home trail, but knee braces are a bit new to me. I'm renting a 250 XC-F in Mid-May and am gonna try the local vet track along with a trail system and see if either spark my interest.
the ktm xc and sx are the same motors as i understand (at least the 4-stroke XCF and SXF are same motors), just way diff trans, sx gets small tank, no kickstand, and 19" rear wheel, and different final drive gearing (to go with the trans)
