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!
