I am in the market for a new bike and love the style and look of the 600rr but I'm also looking for something that gets some what good gas mileage. I saw and have read a little about the f4i and was wondering what kinda of mpg you get. I know a lot of people ride there bikes hard and I do occationaly but I use my bike right now for the good mpg.

So what mpg do you get? Any better than the 600rr?

The F4i does indeed get better mileage than the RR (remember the RR has 8 fuel injectors instead of 4). My F4i usually averages 40mpg consistently for normal everyday riding, though it varies quite a bit depending on how hard or easy you ride it. I've had as high as 47mpg while taking it easy and going slow (~60mph), then I've had it as low as 29mpg running 150-160mph for most of the tank

My bike is brand new (350 miles) and I've only checked the mileage once so far.

41 mpg

modest in-town driving = around 45 mpg for me.

Duel injectors doesnt necessarily mean worse fuel economy, the secondary injectors only kick on at high rpms, so if you keep the revs down the RR shouldnt really get that much worse gas mileage than the f4i. If you like the RR better you shouldnt get an f4i instead just because it gets 3-5 more mpg, at the most. The f4i is probably a better street bike though, but I happen to like the riding position of the '05 RR. You seem to be in more control and over the steering head, where as on the f4i it seems as if the front end rides high. I'd get an RR over my f4i if I had the choice. I put $10 or less in a tank and it lasts me 5 days of commuting. During that time I go to work, school, girlfriends house, and do midweek and weekend fast rides. Over time manufacturers tend to develop ways to use fuel more efficiently, so newer bikes such as the RR shouldnt get that bad of mileage.

On my 02 F4i, I get between low 30's and 50 mpg. 30-40 mpg = constantly on and off the throttle, lifting the front wheel, taking off quickly, etc. 40-50 mpg = normal everyday riding, sensible, longer trips on highways, etc.

Probably pretty much the same, same engine, just different injection. I can get in the 50's if I keep out of it commuting. Cold weather mileage is worse. I added a power commander, and have not checked mileage since, will have to check it.

Between 38 and 41 mpg.

41mpg

I have the RR.... I made 47mpg on a trip before. Fill the tank up and set the trip meter. Rode until the group stopped for fuel and topped it off again. I used about 3.5 gallons... did the math and came up with 47. That was a group ride, nice and slow around 45MPH most of the time. So, my point is... the MPG varies greatly depending on how you ride. I could never see 47MPG with my weekly commute back and forth to work. I usually see about 35mph but I'm playing with new gearing...

all I know is it gets better mileage than my old F4
maybe cuz my F4 had -1/+1 sprockets but still

Man, you guys get good mileage....I just checked and it was 31. Maybe I'm not riding it as easy as I thought I was. :)

There are way too many variables: gasoline octane, fuel quality, machine condition, altitute, rider weight, rider technique, shifting points, gearing or engine modifications, etc., etc.

It should be a little higher than 31mph. Where are you shifting? If I'm riding aggressively, I know that my mpg is going to fall like a rock.

I prolly shift around 5-6K for a bigger road...a little lower for smaller roads, and higher for freeway/feeder roads. Its pretty new to me, so I still like to hit it hard once in a while....10K shifts.

I'm down low in elevation, so I assume that more air would cause the computer to pump more fuel.

i get 40-46 a tank, of course i ride pretty easy. no hard riding.

I can locate that on my cars dash, but on the cbr f4i how do you reset the tach or gauge to start at 0?
I just filled up my tank to full, and thought i tried to measure my mpg, or miles per tank

press and hold the button on the lower left side, you should find a owners manuel for your bike it helps ! I get 41 mpg

Its kinda of odd that you guys actually monitor the mpg on the F4is. Its a sports bike, is fuel efficiency really important to you? Shouldnt you care more about performance? Anything in a sports class can not have both efficiency and performance and if you think otherwise than the salesman did his job.

When gas spikes again and it's $4 a gallon (you know it eventually will), then yes it's important when my truck gets 10mpg.

Shouldnt you care more about performance?

Do you race to work every day? When I was commuting on the F4i I rarely got above 10K.

You really couldn't be more wrong. How do you make more power? You make the engine more efficient. Since we are now working with electronic fuel injection you can set your lower RPMs to be very efficient while still maximizing power where you need it for racing. With mods like a Power Commander you can actually run several different maps on the bike. You can have one for daily commute and one for racing.

To the Original Poster, if you want a street bike, you will be much more satisfied with the F4i. It dosent give up much to the 600rr, and is WAY more comfortable.

I ordered one last week. Still waiting for it to be mailed ... duh..?

blackdog thanks for your response! i totally understand

Agreed! And when you commute on your bike 100 miles per day 5-6 days/week like I do (and others as well), MPG sure as hell does matter!

MPG has more to do with how hard you twist the throttle than what RPM you shift at.
