When you ask about sprocket size are you referring to pitch/width or tooth count?
For those running Windows, press "CTRL - or +" to reduce/magnify picture size on your screen;
press "CTRL 0 (zero)" to revert to tthe original setting.
CommanderChaos, I have a chain conversion and fitted by mistake
a slightly larger tire;
chain conversion is 17/49 (2.88:1 final drive ratio as opposed to 2.96:1 for the belt drive)
tire size is 140/90x15 as opposed to the original 140/80x15.
Final drive ratio is overall longer and speedo now underreads by about 5%;
I tested it yesterday on the freeway with my GPS mounted on the handlebars, indicated 100 Km/h was 105 according to GPS.
Thanks for the pictures
PS What's the tire size on the rear, pl-eeeze ?
