I haven't picked the bike up yet but since I saved SOOOO much money over the wr250 I was considering, I'm already going nuts on the "extras". I went with the RK x-ring chain, carbon fiber pipe guard from mxdeals<--yeah I know, pricey but oh-so-cool. I've already got bars and guards from my old bike. I need tires--thinking about s-12 rear or 756 for quite a bit of sand. What about a good front? The 773? Also, I think the rear will hold a 120/90-18 right? I'll mess with the valving once I get reaquainted with the kdx. Oh, she's a 2000 kdx200
