    versys 1000 sprocket change

    Two of my friends ride 1000 sx machines ,they have changed the sprockets to raise the gearing ,I have done the same in the past on previous bikes because i find first gear is a bit too low (unless your riding with a side car ) recently i have been out on my v1000 and finding first gear is quite low ,in fact its easy to pull away in second ,(provided you select second before you come to a halt ,as the neutral finder will not allow selecting second gear at standstill) so my question is what would be any drawbacks ,IE altering speedo and traction control settings ,my friends were experimenting to lower the revs at 70/80 mph whilst touring for fuel economy ..so smaller rear or larger front sprocket ,,? over to you experts please /

    You will find lots of opinions on this, but I went down 2 teeth on the back sprocket (43->41) and found the results quite satisfactory with no down side. Others have gone from a 15 to 16 tooth front sprocket and found similar results. Some have made changes to both sprockets. All of these changes have generally been done to reduce the rpms for more comfortable higher speed touring.  In stock form, the engine feels a bit "busy" for most riders when running at 130+ km/h.  I found the Gearing Commander website most helpful when making my own decisions about gearing changes  - http://www.gearingcommander.com

    Hi Bully, are you aware that the sprockets on the 1000sx are different to those fitted to the Versys, resulting in an sx producing higher rpm to achieve the same speeds?

    You may find that in changing their sprockets, the result becomes the same set-up as standard on the Versys. 

    Swop sprockets with them and then they would be left in the weeds due to your new found acceleration from standstill  :152:

    I used a front sprocket with an extra tooth, this resulted in minus 500rpm in 6th at 80 mph.
    And, I didn't notice any difference when moving from stationary, even two-up and fully loaded.

    The biggest problem was removing the sprockets securing nut, and I had to get help from a tyre fitter and his impact gun. It was soo tight.  :003:

    Good luck with your plans, Vern

    Hi Vern ,
                Yes your spot on , we rode together and discussed RPM at the same speeds , they were rvving higher and on a holiday trip they were using more petrol than me  ,,still thinking about this Thanks ..Bully

    Here's a screenshot from Gearing Commander with the stock gearing for the big V preloaded:

    Fiddling with the Gear Commander calculator, 16/41 looks great to me. You could go one sprocket at a time and feel it out, but if both were changed the 70mph rpm figure would be great and getting off / creeping along in 1st should still be no problem. There would be less shifting to get to typical town  speeds as well. When I am riding along on city streets I like to sit near 3Krpm, because there is both strong acceleration and useful engine braking available from there. Generally speaking, that spot would arrive in one lower gear with 16/41. Hmm...

    +1, the 16/41 ratio works well for me.
    This is a bloody great Bike....!

    At 16/41 your chain and sprockets (the front in particular) will wear much faster due to same the chain link hitting the same tooth on the front sprocket every 4 rotations (as opposed to every 15 rotations at the stock 15/43). The stock ratio bassically gives you the least possibke wear.

    Anyone tried 17/43 on V1000?
    (Assuming OEM is 15/43).

    Why would the the same tooth hitting the same chain link more frequently result in more wear that the same tooth hitting the same link less frequently, when that tooth would in turn hit different links more frequently?
