Gearbox ratios ST2
Odd one this...my'98 ST2 fitted with 15 tooth front and 42 tooth rear sprocket revs too much (about 85mph @6,000rpm).
I've fitted a 39 tooth rear sprocket and it now runs just under 100mph @ 6,000 rpm.
The later bikes run 15/42 sprockets but seem to do around 100mph @ 6,000.
Anyone got the gerarbox and primary drive ratios for an early ST2 ?. Must be a change in the gearbox and my guess is it's the primary drive ratio that's been altered as it would be a real pain to change all the gearbox ratios.
