12oclocker Posted January 19, 2009 Report Share Posted January 19, 2009 (edited) I wrote a little tool that you can use to calc your top speed at any gearing, usefull to figure out the top speed of your bike when regeared,also usefull to calc a good gearing for you next bike, once you've found that optimal setup.you basically just fill in the form with the gear ratio info from the bike service manual. I have already prepopulated the form with a few bikes I looked up myself, if anyone else has some bikes they would like to add to the list, just pm me the gear ratio's and I'll add them.I usually just give the local dealer service department a call if I don't have a service manual, and have them look up the gear ratios for me.I know there are some of these already on line, but I could not find any that were very accurate, so I made this one Link...http://www.12oclocker.com/gearcalc.htm Edited January 20, 2009 by 12oclocker updated the link Quote Link to comment Share on other sites More sharing options...

xtremef4i Posted January 19, 2009 Report Share Posted January 19, 2009 Nice tool Brooks. I'll check it out when I am at home with me manual. I have the Haynes book for my bike, so I dont know if it has the gear ratios listed in it. It would be cool to see what my actual top speed it at my current set up vs. what my speedo says with the speedohealer Quote Link to comment Share on other sites More sharing options...

xtremef4i Posted January 19, 2009 Report Share Posted January 19, 2009 thanks, I'll be adding more bikes as I get bored, lolIf you are bored you can add a 2001 CBR F4i, lol The 2008-present Ninja 250 seems to be pretty popular too. A lot of people might like to see the eager 250 get some attention in the eyes of potential performance upgrades. Quote Link to comment Share on other sites More sharing options...

Good work man. My manual said different ratios for the F4i. And the top speed with stock gearing would never hit 173MPH. More like 165.Oh and my manual is Clymer Quote Link to comment Share on other sites More sharing options...
12oclocker Posted January 20, 2009 Author Report Share Posted January 20, 2009 cool, post up those gear ratios, and your bike year, I'll add em to the list Quote Link to comment Share on other sites More sharing options...
xtremef4i Posted January 20, 2009 Report Share Posted January 20, 2009 cool, post up those gear ratios, and your bike year, I'll add em to the list I posted them in post 14 (provided that manual has the same numbers as Honda manual). The00-06 F4/F4i should all have same ratios I would think. year 2001 F4i Quote Link to comment Share on other sites More sharing options...
12oclocker Posted January 20, 2009 Author Report Share Posted January 20, 2009 (edited) oh you did, lol, im blind, lolHey I added the 2008 Ninja 250R, and a slew of other bikes too, lol you know whats weird, the honda fiche shows the transmission on those bikes used the same gears from 99-02, in 03 the changed the transmission gearing.

You da man Stan...you da man.Hmmm I wonder if the 03's are any quicker than previous years. I always heard 01 was the quickest year then they toned it down ever so slightly in 02 Quote Link to comment Share on other sites More sharing options...
12oclocker Posted January 20, 2009 Author Report Share Posted January 20, 2009 (edited) you know whats even crazier!!!, the 07 gsxr750 is may be the fastest production motorcycle, lol. faster than even the zx14, if both were at last gear, and at redline, and totally stock, the 750 would be about .3mph faster!, now we all know the zx14 would get to top speed quicker, but its just crazy that the 750 is stock geared for a higher top speed! this is using the rear tire dimensions, and sprocket, and transmission ratios, and redline info for each bike, lol.07 gsxr1000 top speed stock: 197.306 mph at redline07 gsxr750 top speed stock: 206.405 mph at redline09 zx14 top speed stock: 206.129 mph at redline Edited January 20, 2009 by 12oclocker Quote Link to comment Share on other sites More sharing options...
