I didnt compete but I rode for yearssss....I used to run open track days though. I never had the time to race for real...Here are 2 of my 3 old rides.
I had a 02 blaster
Then this 03 KX100...Seriously modded. I prob had 2k into this it SMOKED banshees in a line and forget on a track
Latest but I blew the engine. 2001 Raptor 660r. Basically just threw 18s on the rear and changed the sprockets. Tops out at 85mph
KX and Raptor ripped wheelies in 6th gear haha
