Just curiouis.My buddy is thinking about getting a 400and wanted to know how much more top end it had... Thanks for any help..

Trae....

 

52

 

Top speed for a stock 300ex: 54mph
Top speed for a stock 400ex: 68mph

The 400ex is a whole different motor compared to the 300ex. It's not just a "beefed up" 300ex motor. The power is an increbible difference between the two. However both are awesome machines in my opinion.

 

Thanks Guys.I knew there was a big power and handiling Diffrence.But just wasn't sure on the top speed.I did guess them both within 2 mph though...

i 300ex goes alot faster then 54. id say about 63. i was going 53 on my rancher and my friend passed me on his 300 going alot faster. he has a dg pipe, but that dont increase top speed

 

LOL TRX350dude your alittle off buddy[img]i/expressions/face-icon-small-confused.gif[/img] 55 is as fast a a stock 300EX will go. You were going 45 on your rancher and he was going 55, there you go I bet thats what really happend.

 

yea...ther is no way in hell the stock 300 would even come close to 60..i think you need a new speedometer

 

i dunno dudes when mine was stock i got clock by one of my friend on his on/off road bike and i got clocked at 59mph. It all depends i guess

 

Sorry to say but all speedometers on ATV's and dirtbike are just about always 5 or more MPH faster then there really going.

 

Dual Purpose [on/off road] bikes are required to meet federal speedometer calibration standards. ATVs and Enduro bikes are not. That's why most of them read inaccurately.

Also keep in mind that no two bikes off the showroom have the same performance. This has been shown to be true in both ATVs and streetbikes. It's not unheard of to see a 300EX hit close to 60mph. But I think 63mph is a little too far fetched. Maybe if the rider only weighed 100 lbs. and was riding with the wind.
