Ritey Posted May 1, 2006 Report Share Posted May 1, 2006 drop gear ratios to be precise. I need to know what the effect on the final drive each of these will have: 1.1 1.043 1.087 Ta Quote Link to comment Share on other sites More sharing options...
Ritey Posted May 1, 2006 Author Report Share Posted May 1, 2006 Ok would I be correct in saying that a 1.043 ration would be best used to achieve a high final drive ration? Quote Link to comment Share on other sites More sharing options...
rhyds Posted May 1, 2006 Report Share Posted May 1, 2006 Errrm, in my reckoning (i'm in no way at all sure of this) 1:1 would be a direct drive 1.403 would be a reduction gear 1.087 would be a bigger reduction to raise the final drive ratio (to make the gearing "taller" or higher) then you would want as small a reduction with the drop gears as possible. the two reducing ratios will "shorten" the gearing (I think), and make it lower overall Again I stress I'm not sure of any of this Quote Link to comment Share on other sites More sharing options...

[/ QUOTE ] Yes 1.043 would give the highest gearing out of the ratios you quoted. Quote Link to comment Share on other sites More sharing options...
R32Ash Posted May 1, 2006 Report Share Posted May 1, 2006 There's free software kicking about on the net, for working out what difference you can achieve by changing the final drive etc. I downloaded a program a while ago when I was considering changing the gearing on my CBR600, but I can't find the software now. Edited to add I've found a program if you want to try it Ritey. You can d/l it at the bottom of this page. Quote Link to comment Share on other sites More sharing options...
