Stock……lol……those other guys he was racing can't race. I left a comment on that video….if he gets off his 400EX and lets one of those guys race it and he gets on any of their quads he will beat his own machine every time. Thats the true test and something we use to do when we raced, thats how you find out. You can get a honda trx90 beating a banshee on video.

Other guys can't ride, a modded 400EX can barely hang with a stock 450 with a competent rider. The 400 is a great quad, but is no racer by any stretch. You want speed, get a 450 or an old 2 stroke, the 400 isn't the ticket for top speed racing! Lol
