You hit it right on the nuts. Stock is 59 to 60mph. You ex guys might get pissed but its true. How about you Hondabuster what you think? You had the gps that day, 400ex = 59mph.

 

Only the trolls or the kids in grade school think that a 400 goes much over 60mph. No one that actually rides one ever said it went over 65 I don't think.

 

I have an 05 400 EX with a pipe, filter, and air box mod and am positive it goes about 70 MPH inside the trailer on the way to go riding and tops out at about 60-62 when I am actually riding it. The mods help it get to that top speed faster but don't make it go any faster than my wifes stock 400.

 

2007 Chevy Corvette: 186 MPH top speed, $45,000+

2001 Honda 400EX: 185MPH!!!!, $2000 probably less

wow unless my math is off a 400EX almost keeps up with a new Corvette, I think I'll save myself thousands of dollars and buy a 400EX and get the same speed... Listening to people talk out of their a@@es on the internet= PRICELESS.

 

Thats what I thought when I bought my sportbike... :-)

 

i finally found how to make a 400ex go over 130 mph on flat land 160 down hill 80 up steep hills by puting a sports bike engine in between the frame and ill be doing it to my 300ex. i lost my mind lossing to 450r, 660 rapters, ds 650. now they will be eating my dirt =) yaaaaaaaa!!!!!!!!!!!!.having a procom rev box didnt help

 

He would have had to followed with more than a dodge pickup![img]i/expressions/face-icon-small-confused.gif[/img]

 

Older 400ex's go 65mph. The newer ones i think 05 and up to top at 55mph. To make it faster you gear it taller and run bigger tires. Well yo ucan gear it tall and set teh top speed at 80mph put a 400ex motor wont have enough power to pull 5th maybe 4th even posably wont be able to pull3rd gear wit hthat tall of gearing. You need to highly mod a ex motor to be able to pull that tall of gearing. The fastest quad was like a raptor660 with a rocket motor on back that hit like 130mph.

 

Ill only do good in streight lines. The highest i could brobable get my quad to run is a little 0ver 100mph with gearing. Its a 400ex to but gots a 50hp yz motor.
