    Here's a technical question but specific to Sortsters so I hope I have posted it in the right place!

    I am keen to buy a tacho kit although for the present time I cannot pick the revs of the bike (all based on "feel" like a good v-twin should be). I am curious though, what the speed is per 1000rpm in top gear. A number of factors need to be considered:

    -My bike is a 1998 XL883
    -Have the ratios/revs changed over the years since belt drive commenced?
    -Do 883/1200 have the same final drive ratio?
    -Is the final drive 1:1?
    -How accurate are Harley speedo's?

    If anyone can give me the figures in mph I can easily convert it to kmh!

    Thanks Hobbit, you have answered some of my question, if solid mounts had a different ratio then someone with the same vintage will probably only be able to give me a definitive answer. Cheers mate!
