Do Iwant an F4?

I had a Brutale 910s for a while. It was a great bike and I really enjoyed except for 2 aspects: the 'light switch' throttle at low rpm and the overly stiff suspension. I could live with the suspension, but the snatchy throttle made me crazy. I tried removing the extra spring and all that, but nothing worked and I eventually sold it.

I'm still a huge MV fan and have always loved the F4. I'm considering an '05 1000s. Am I likely to find the EFI mapping as bad as the Brutale?

Having never ridden a Brutale I dont know.

There will be fueling issues with that model unless you spend some serious dough getting an ecu upgrade, exhaust (not required but I would recommend it) and probably some proper tuneup.

That's just crazy talk.

All joking aside, I'm sure you'll find the throttle issue exactly the same. If it bothered you that much, I'm sure it'll bother you again unless having sold the Brutale, you realize that you love everything else about the bike more than you hate the throttle.

I have an 05 and a Brutale. The throttle on the Brutale was very grabby. To compensate for it I dropped from 43t in back to 41t and I have to say it feels much more like the 05 1000.

You can always adjust the suspension to make it feel softer.

you'd rather go for a 1000R (Euro2) no cat with a race ECU but careful those bikes don't like traffic at all

The throttle on my F4 is very smooth and not at all grabby or snatchy. There is a surge @ 3000 rpm but it's the engine, not the throttle.

Having been a Brutale owner kindly keep in mind that the F4 is alot more bike in several areas not the least of which is it's "chick draw" factor. They'll be all over you which is why it's soooo much more performance oriented. So you can get away before they tear your clothes off.

I got mine. Boy do I ever got mine.

First off, you shouldn't have to "live with" anything you dislike about a bike (any bike). The suspension is harsh as delivered but has enough adjustability to make it more compliant without spending any money. You just have to turn some clickers and find what you like. If you want to spend some money you can buy a new shock and have the forks reworked for more compliance, although the Marzocchi's are less known and are more difficult to get things like different spring rates.

As far as the throttle goes, that is also fixable. I found on my F4-1000R that there are a couple of things that really helped the low opening sensitivity. Fuelling is the biggest thing with the bike being very lean on the bottom. Enrichening the fuel mixture (you can do this with the idle co% trim adjustment) will make the sensitive throttle much more forgiving and easier to ride. You will pay a price somewhere though because it will change the entire fuel curve a little (because the trim adjustment is basically the zero point for the fuel map on the open loop systems) but it isn't that noticeable. Second is the throttle cable free play. My bike was delivered with a ton of slack in the cable which I immediately adjusted out. This also makes it easier to transition on-off throttle. The last bit is the final drive lash which is adjusted out by keeping the chain adjusted. it only takes a couple of minutes to adjust the chain, so adjusting it every couple thousand miles isn't a big deal.

So to answer your question, get the MV if you are willing to deal with the problems you know are, will or can be there-they are well documented here on this site. Otherwise, I would get something else which may have it's own set of issues.
