Good Part

The BBR Rev box for my crf50 was a good purchase. It supplied a power increase and removed the rev limiter as promised. The power increase was small but what do you want for something that is really just plug and play. Installation was easy, I just had to remove the old computer and install this one in its place.

REV IT UPPPP

I installed this on my 08'CRF80 and it definitely increased the over rev in 3rd and 4th gear. You get more torque and gearing into your bottom end. I love this product and will put it on any other pit bike i get!

You won't regret buying it

I bought this on 11/23/09 for my honda crf70f and it came 11/30/09 it was easy to install although the original hanger didn't fit because this box is a little bigger than stock but i tied it on with a zip tie and stayed there just fine i definetly felt more throttle response and more power on second and third gear i am really happy i bought it and its a cheap power booster. Here are some pics

Rev it up!

My opinion of this product was that it really didnt do that much other than let the bike rev up a bit higher. For a cheap modification that you may notice with a big bore kit i would reccomend it as something you do later on. Dont use it as your first priority.

A: Fitment cannot be guaranteed on the SSR125. These BBR rev boxes are designed specifically for Honda minis (xr50/crf50, crf70, crf80, crf100).
