Not to burst your bubble, but I would call Bazzaz and see what the gains would be for the GSXR's. Bazzaz explained to me after I bought it unfortunately,the ZBomb is not a TRE for the GSXR's. I got rid of mine because the ZBomb was only a top speed eliminator and may help smooth out throttle a bit. You will gain absolutely no HP gains like some of the other Honda's . I like and use Bazzaz products but if you want a TRE go with something else if this is the case for you bike.
