Right, I have posted this in response to what was being said in another thread, but as I’d like to think it was use to many, I have made this new thread.
A bit of background:-
I generated a bit of software for myself so I could easily see the effects of changing sprockets. Using the engine revs, wheel circumference and gear ratios, I could mathematically calculate the theoretical speeds in each gear with different gear ratios/sprocket combinations. It was actually based around my R6 racebike; as base setting sprocket combinations is always a bit of a head scratcher.
But as I now have an SV too (roadbike) and was thinking of fitting a 14t front sprocket, I updated the software with the ratios for my ‘curvys’ ‘box.
Anyway, down to business
There are 3 files available, GearRatioCalculator_SV650.exe, GearRatioCalculator_SV1000.exe and COMDLG32.OCX.
Basically I have looked up the gearbox ratios for both the SV650 (all years) and the SV1000 (for the 1000cc impostors amongst us
) and generated two separate executables using this data. No prizes for guessing which file is for which bike!!
Copy whichever bike you are interested ins calculator to your pc. Some of you will also need the .OCX file too (for the dialog boxes) so save this to the same folder too. Then, well fire up the GearRatioCalculator and enjoy
Here is the URL for the files/folder (that Carsick from here has hosted for me):-

If anyone has any questions or not sure what to do, then just shout
I did write this for myself and I am not a software engineer by trade, so if you don’t like the colour scheme or summin, well I don’t care
but if there is any constructive criticism, I’d be happy to hear it.
Oh and as with all good software realises I better give a short disclaimer …
… I am sure there is proper legal jargon, but basically … don’t come crying to me (or to me via your lawyer)!!!
