I would like to know every difference on those ones. And which one is the fastest. Thanks. Useless post BTW [img]i/expressions/face-icon-small-smile.gif[/img]

 

???????????????????????

 

not sure but have heard the 250x is faster then the 300ex. i have a 250 and its piped and filtered. sure is pretty quick.

 

the i would go with the 300ex because it is more monuverable and probably as fast or fasteryou mod it up and will eventually be as fast as a 400ex or faster

 

from what i've heard, the 250x motor is the same as the 300ex(not really a 300cc, more like 270) and being that the 250x has a better designed frame, id have to give the nod the the x

 

The X Frame is more like a R frame amn't right?

 

id go witht he X suppose to be faster then the ex more Hp then the ex. so i would give the thumbs up to the X also.. only thing i give to the ex is the eletrice start.. does any one know how the x reverse system is? easier then the ex or the same

 

Ive been dealing with these machines since there inception and heres my best shot
250x has 600rpm higher rev limiter which gets it about 1mph higher top speed
250x has stiffer springs and shocks and would be better for jumping but more harsh to trailride
frames and suspension are built on the same jigs and are the same
250x has adjustable camber on front a arms
300ex engine is the same exept for a longer stroke giving it a few more ccs and no compresion release and the obvious electric starter feature.
you can install a 250x side cover on a300ex for a kickstarter backup very easily
250x stock muffler is freer flowing
handle bar plastic has a different keyswitch mounting
reverse levers are a little different but work the same
the plastics are the same but came in different colors 1987 grey ,1988 white,1992 blue/white, 1994 and after red and black with a multitude of decal changes (bold new graphics)
the 300ex choke is much harder to find than the 250x with the starter in the way
They are a great beginner quad but with the 400ex out and going so cheap I would get a 400ex unless reverse is a must otherwise it would be a waste of money to spend thousands hopping up a 300ex to get the great suspension and reliable power of the 400ex.
If you think a 300ex wheelies easy stock you should try one with a 406 stroker engine. The stock chassis just isnt wide or long enogh for serios power without longer a arms ,swingarm ,shocks

 

i have a 250x and it can hang with a 400ex any day. a 250x is faster than a 300ex, with more compression, and it is also lighter. go with a 250x.

 

The reason the 250x is faster than the 300ex is because the 300ex has a shorter rpm range than the 250x, Why honda did that i will not know,and the displacement on the 300ex is 282ccs not 270.
