let me know where you bought that SPECIAL 400 ex. noone seems to have one that does more than 65 or so stock. my cousin has one, he ways 130. his will finally break 70 and that is with 22 inch holeshots on it.

 

I have a 86 trx250r with a wiseco piston and boyseon reeds. I have ather kmods but none that would make it go faster. just like a twist throttle aluminum mitchell wheels. I also have 18/11/8 holeshot mx tires. I am not sure of the gearing I bought It with the same sprokets and chain it has now. anyway I live on a service road that runs right along a interstate and the speed limit is 70mph. I can run right along side the cars but the service road is on a slight down hill. I would say mine does 68 mph.on a level surface. i weigh 135. It will beat my cousins moded 400ex on dirt and blacktop but not n sand where he hooks up better. well cya remember ride red ride smart and most importantly ride hard!!!!!!!!!

 

Dill & Warpt13,

Finally some people who are honest...WOW what a shocker!! Those speeds are also my findings as well. I have argued these speeds with many. But, you know how it goes, liars are impossible to argue with.

I am right with you two. An average weight rider on a stocker gets...70-72 Banshee, 68-70 TRX250R, 63-65 400EX.

 

I've been reading the atv connection for quite some time now and never felt the need to register until now. However, I do enjoy reading all the great posts from the likes of tree farmer and the rest.

I realize I shouldn't even waste my breath on claims like 400exalltheway's, but I've seen this too much and it really bugs me! I doesn't matter if you weigh 2 pounds and your machine is piped cammed, ported, polished, air box gone... whatever, your machine WILL not go any faster than what is mathmatically possible. With a given gear and sprocket ratio, along with a given rev. box limiter - that's how fast a machine will go. It ain't rocket science! On the 400ex, for example, its average max speed is about 63-65. It will not go faster because of the gear and sprocket ratios and rev. box. If these aren't modified - you ain't going any faster. period. Thanks for letting me vent.
