According to the British magazine Performance Bikes in their test of the Sukuki GS500F in the August 2004 issue here are their numbers for your bike.

Top Speed    112.22mph
0-60MPH         4.6sec
1/4mike         14.18sec   @ 98.51mph
Average MPG       54mpg
BHP      39.2 @ 8360rpm
Torque    25.8ft-lb @ 7400rpm

Wow, thats interesting....I've never come close to getting that high of a MPG....I'm usually running around 35-40 tops, but then again I hit the redline just about every shift.....       so that could have something to do with it....and the rest of my problems....

jamesmcb,
That mpg will be for a UK gallon 4.54L or 160 fl oz whereas a U.S. gallon is 20% smaller at 128 fl oz. Your profile does not give your location but I suspect that is where the difference lies.
We both use eight pints to a gallon but a US pint is 16fl os and an imperial pint is 20 fl oz which is why you fall over after less drinks over here.

i'll have to try again on 5th gear cause I could of sworn the gearing wouldnt allow it to go faster than 100mph (and I just read gearing allowing it to go 125)... On 6th Ill hit around 190km/h wich equals around 118-119mph...

THOSE who have wobbles, you may get a really nasty fallling off your bike suprise if you slow down during a wobble. Thats the worst thing you can do.... if your front end starts to chatter, braking is putting all your weight on the chatter... If you still have a bit of power left try to put less weight on the front while accelerating out of it. If, and only if it gets worse you can try to smoothly deaccellerate out of it. But the GS will wobble pretty easy in high wind or high speed and you can get used to it, and usually if you dont panic your ride will go on uneventfully. Also if you experience a bit of wobling make sure your tires are ballanced, make sure your bars are straight and that all your front end is properly torqued (the last ones are mostly for people who have gone down and fixed their own bikes).

I've been 145mph on a CBR F3... and i've been passed by bikes in the group I ride with going close to 160mph on one wheel (namely a gixxer 1000 with a crazy rider, and i've seen it happen with an R1 too)...  After a while, top speed really doesnt matter anymore, its really just there for stats purposes. To either better your bike mechanicly or better your riding abilities.

Really?  That's not very good.  Is your bike stock, or has it been rejetted, etc?

My bike is stock as far as the engine and carbs and exhaust, except that I have a restricted K&N in-airbox replacement filter (which is supposed to be fairly equivalent to stock).  Here are the calculations from the gas station receipts I have lying around (just the handy ones):

04/23 -- 171 miles, 54.8 mpg
05/01 -- 58 miles, 62.8 mpg (should probably toss this out because of the low miles)
05/31 -- 149 miles, 57.5 mpg
07/16 -- 161 miles, 53.4 mpg
07/31 -- 124 miles, 51.0 mpg
08/06 -- 161 miles, 50.0 mpg

08/26 -- 184 miles, 59.2 mpg
09/11 -- 188 miles, 58.2 mpg[/list:u]Gee - I'm glad I went through this little exercise.  Did anybody else notice a pattern?  According to my maintenance records the only significant thing I did between 08/06 and 08/26 was change from dirty Mobil1 15W30 to clean Castrol Syntec Blend 10W40.

Wait ... possible false alarm.  According to my

ride records, the last two fillups shown were associated with road trips -- highway miles.  I guess I get much better mileage "out there" than in town.  (Duh!)

Well ... MAYbe.    But if you get that valve adjustment done you just may find some missing mpg AND some missing power as well.  Just ask richard!

Why is it that bikes need these frequent valve adjustments while a car engine can go the life of the engine in most cases without anything like that done to it?  Is the car engine that much different?

As far as the bike goes I think it is all stock to my knowledge.  As far as being rejetted, to be honest with you I dont even know what that means....

That's a good question!  I know that many of the latest-generation bikes (or maybe it's the higher-priced bikes) have valve adjustment intervals of 15 or 20 thousand miles or more.  But I would like to know more about the differences between bike and car engines too.  (Besides water cooling and fuel injection....)

Don't worry - you'll get there.  But don't worry if it turns out that your bike is still "bone stock".   I like it that way!

If you adjust your valves and still end up with low mileage figures, THEN let's look at your carbs and jetting, etc.

just throwing out a guess here... but car engines don't rev to 11k usually.

202 mph indicated on the GPS riding out in the Lake Okeechobee area, speedo long since pegged.Oh, wait a minute, that was the Busa, my bad......

Are the F models more stable at top end with the bodywork added?Seriously, the Busa is so stable at the 200 mph mark, it's frightening. doubt my wife will ever get her new F up to triple digits, but I am sure I will.
