How Fast?

[95300exrida]

i was just wondering how fast you guys think my 400EX goes. all it has on it is K&N filter and 22inch bear claws. I can keep up to cars on the highway (100ish km/h ish or 62ish mph) at half throttle.

top speed?? 78-80 ish


maybe even more with some go fast stickers.

A Stock 400 goes 68. if your quad is jetted right and with the bigger tires you might go a little over 70

i always thought smaller tires made it go faster maybe i thought wrong

[bubba's400ex]

no smaller tires give you more acceleration because the circumfrance is smaller.

theres no way his top speed is 80 they have about 1,000,000 threads about this some even include a handy top speed calculator, all you do is plug in your tire size and it tells you the top speed maybe sombody will post it for ya or do a search

Those calculators aren't accurate.
Something is usually off. Like the rpm limit, or the drive ratios aren't right.

Here's what the calculator you're speaking of says at the 400ex's rev limit, and 22" tires.

Granted on 22's w/ stock gearing you'll never see the rev limit on a stock motor.

i searched for the calculator and tried it in all different ways anf theres NO way that it is right. who here can do 30MPH in 1st gear on a 400 ex?
