426

[Honda TRX250ex]

How fast are the 426ex on a MX track compared to Z400 and other quads

[ride_red666]

depends how good of a rider you are....

If your a good rider then the 426 will be faster then a z thats pipe ETC.

426's by themselves with everything else stock are dogs, however, have you ever saw one? I didn't think so. Most people that have a 426 have at least a pipe and probably a cam. When all of these mods put together the bike rips.

definitly have head port work done, cam, pipe, airfilter to compliment the 426 and u will be very impressed with the power gain. Not only will it run off and leave any other 400's u will be pushing piped 450's :macho . That is if u can ride it !

ive seen a duncan 416 with a cam blow factory 4 piped 450r's away (in a drag race) by 4 bike lengths or more

And i could be 2 bikes behind a 13:1 with cam before my piston and cam i dont know what it can do with that piston and cam cause just put on today. still breaking it in.

but when racing on a track due to stock shocks makes hard to even compete.
