400EX Vs. 250R

Not to start a R/EX war, but the R is faster off the line and has a wild powerband. The R also handles better and turns more precise. The R will out carve the EX . I'm not saying this is better, just a difference. The R don't have the luxury of the EX. It vibs, kickstarts and tends to scare you once in a while when the powerband kicks in.
The EX should have been called the 400R LX Edition.

One thing about the speed comparism. The external gearing of the 2 quads is totally different (400ex-38/15 and 250r-38/13) with the internal gearing being relitavely close. Change the gearing on the 400ex to match the "R" and that holeshot may go away and maybe the top end will change a bit too considering that the 400ex just plains out (will not pull as many RPM's) with the tall stock gearing.

Gary C I can't argue with you there. I've seen that done on a Warrior and a Realter racing tire/wheel package added. It to gained speed all the way through bottom to top. A shorter stance would also help the EX. With that combo even a less skilled rider may be able to beat the R due to the smooth power band of the EX.

The 250R has the supierior power advantage even stock vs stock. The 400 is a awsome trail machine and probably a good MXer but in the sand pit or drag race the 250R is the king. The 400 has more suspension travel than the 250 which makes it a smoother ride. 4 strokes are more reliable but if you want some radical acellaration than get the 250 The 250 is cheaper to modify than the 400.

I have an 86 trx 250r and my cousoin has a 99 400ex in the wooods I beat him and on the drag stripo I beat him and he has the same gearing as my 250r 14 tooth counter shaft sproket and 38 rear sproket he also has a dynojet kit and K&n filter when my 250r was completly stock I could beat him on black top I feel the 400ex has a lot going for it though
