I tell ya what Kev. You like ribbing me so I got a deal for ya. I'll race you with your 20+ years of biking and my 20+ years of motocrossing whatta say we do a double. I'll race you at 6 mile after you race me at Hurricane Hills Mx track. What do you think? Fair? Just for fun. I'll even let you ride a bigger displacement bike, say 450 vs. 250.
rTalk though, we are talking bikes here and you bring in motorcycles. I guess we can add a third challenge on a skateboard and then you can add another one that suites your skills.
