Brutale gearing changegreenspun.com : LUSENET : MV Agusta F4 : One Thread
Hi, Thinking of going to the 15T front sprocket on my Brutale. Has anyone done this or any other gearing changes on their Brutale?. Will I get enough adjustment out of the eccentric to avoid a new chain?

Doing the same thing. The final 6th gear is much lower than the F4 models as is the final drive. This, what I read, is in keeping with the design intent of the bike. No need to go 170 MPH on a naked. My dealer said either go 15 in the front, or 38/39 in rear. Someone else emailed me and said they did 15 up front and it made the bike so much usable through the gears, plus, it is working about 800rpm easier in top gear at 65 MPH. Good luck. Talk to your dealer. Don't know if you have to go to a new chain.

I talked to my dealer about going to a 15T last weekend and he just looked at me as if I was some kind of nut. "Why would you mess with something MV spent millions of research dollars to perfect"?
The question is, do you really want to give up power coming out of the corners just to save 800 rpm? If the roads you ride are primarily level and straight then sure, tinker with the sprocket. But if you ride primarily winding, hilly roads you'd be foolish to change factory specs.
My bike is turning 6,000 rpm at 70mph. That's alot compared to a twin but is really not even half-way to the rev limiter. This engine was designed by Ferrari and MV to spin and spin. If you want to cruise comfortably at highway speeds buy a 2nd bike. The Honda ST1300 will get you down the highway in great comfort and will also let you go 330 miles between fill ups.
