Can you ride the 06 on a mx track in mostly 3rd gear like the 03 4 speed. I sold my 03 but I loves the idea of not much shifting. 2nd for tight turns and maybe 4th on long straights. Wow that bike had power. I get my new 06 this week and i hope I like the gearbox. I am a 38yr old B rider. The 4 speed made me lazy. Twist and go,like an automatic.
