I just bought an '07 YFZ450 that is very modified (built motor, fast, long travel a-arms, etc). I have been a two stroke (Banshee and dirt bike) guy my entire life (well since I started racing MX when I was 6). I know the Skat Trak Extreme 22x11x10 (9 paddle) works really well for my Banshee. What should I use for this YFZ in the Oregon dunes? I was thinking about going with the same setup and am going to throw them on it this weekend for a test run, but has anybody tested things and found what is the BEST? My riding style now is tree shoots, worm trails, hill climbs, and a basic run from Box Car to Spinreel. I have always been the fastest quad out there in drag racing and want to keep that reputation, but if the YFZ doesn't do as well as the Banshee, then I'll use the Banshee for drags and the YFZ for casual/track. Please let me know what you think.
