Rev box

[Nate_450R]

what company makes a reliable rev box for not real expensive? and is it really worth the money? were you all able to tell a definate difference after you put it on?

[nowukno]

Dyna & Vortex would be the best but there a little expensive. I have an ESR and it's defintley not a Dyna or Vortex but i was happy with the results. It was a noticeable difference and it was only $100.

definatly not worth the money unless you are hitting the stock rev limiter. the dyna and the vortex are the only ones i have seen on a dyno that did not lose horsepower over the stock rev box. and even when using some curves on the dyna and vortex you will still lose horsepower over the stock rev box.

get one you can program, if it is not programable its a waist. all they do is change the timing and rev limit and the spark. i wouldnt waist my money on one you cant program because you cant change it for the differant things you do to the bike. so you can fine tune it.
