Have question, cannot figure it out. Me and my friend have 08, 09 ktm 450sxf.. both have suspension redone. I sent mine out, his was done when he got his bike. His suspension is much softer, mine much stiffer. I am good 30lbs more then him. When either one of us ride my bike (stiffer 09) it is much harder to get distance when doing jumps, doubles, tables, etc.. very noticeable difference. When either one of us ride his bike (softer 08) it take much less work to jump further. I been thinking it was my weight, being have followed some over tables and double and being a little short. Now it is looking like something with bike setup. Any ideas why? To me having a stiffer suspension seems like you might jump further, but I don't have enough experience to know?
