Rev box???

[yellow400ex05]

Is there any brand that makes a rev box for a 250ex that give's it up to like 500 more RPM's? And are rev boxs worth buying? What do they do besides letting your quad rev higher? can they go faster?

you really dont benefit from them that much unless you have some other mods like a pipe, cam, and a filter.

i bought mine for my warrior and i didnt get any more power that i could tell, so a big hell no on the "are they worth it"

Well as for your oringinal question, big gun makes one that allows 1200 more rpm's or something like that.
