it has to be a lie. even if the guy had the 800cc a 500 banshee should still be able to outrun it. i don't know how much the nitrous and super charger would add but i don't think so. as the guy refuses to answer our questions. i think he just saw him goin fast and he was like wow! that has to be like 130!

About 8 or so years ago there was a highly build Suzuki 500 with turbo and nitrous at the salt flats and its top speed was 125, so I highly doubt that a 400EX with motor work is going to get anywhere close to that... I would guess it is probably going aorund 80-85mph...
Any pics, video or a more precise list of the mods that are done to this 400, maikly a list of what was done to the engine???

For a 400ex to do 130 mph it would have to have some where around 60-70 bhp or more with alot of gearing and alot larger tires on the rear. I ride a CBR900rrr and have been clocked at 162mph by the gun and I know I would almost p!ss myself if a seen a little 400ex quad pulling up beside me at even 100mph. A FZR400 street bike only does 120 mph and it is alot more stream line and less drag then a 4 wheel quad.

not all 15 year olds are immature, i am 15 myself. i am taking a class through the mail on motorcycle repair, the one advertized in the mags. i havednt got below a 95% on any tests yet, so i kinda know what i am talking about in some of this stuff. no, a 400ex will not go 130, but i can see where you could think that if you where never on a very fast quad before. when i was younger i thought my trail boss 250 went 65mph. quads are very deciving. cut him a little slack. you never know he might have some proof! it sounds like a sweet quad. i agree, i think she went about 80-85. oh yeah, onefast453ex has more than a twist throttle and a missing airbox lid, he probably has one of the fastest 400ex's on the fourms. (that still has a 400ex motor and is not set up for drag racing) i think you should listen to the guys that know what makes the ex tick mudslinger. your giving us young ones a bad name!
