Speaking of pro suspension. I havent even ridden my bike yet and Its in the shop getting a $2K suspension upgrade. I have the Devol pro's putting in the works. I probably should have ridden it before I spent the money but suspension is the one thing I never trust with my life. I'd spend up to 5K but they don't have a package like that and Devol is doing pro suspensions so I'll take it. I also bought a pro metal grill alloy radiator guard and skid plate with wings. I've spent close to $11k so far. I'm racing 2 days a week and riding different tracks 3 to 4 days a week so I have to have stuff that dies hard.
Speaking of totally pro bikes. theres an '06 or '07 YZ250F that was a spare for the Bookoo team for sale in the Seattle Craigs list. It was given to the riders buddy fully intact (pro-circuit factory build). The bike is completely bad @$$!
Man, i would have to say that from reading your posts, you are either a little too paranoid about the stock stuff, or you just like to spend a lot of cash. All the aftermarket parts in the world don't necessarily make your bike better, they may customize it or change it, but not always for the better. And about riding your bike before you sent it off to devol, i say you should have with a resounding YES OFCOURSE. How can you tell them what needs to be improved when you don't know what your starting with?
