I don't like the gearing on my 2010 STR, geared for racing , love the handling but I'm not arsed about maxxing it out every gear so I went the other way, +1 front and -5 rear ( I think) to give an 18.8% increase in final drive & changed the ECU to correct the speedo.
Ok, so I lost a bit of the punchy, off the mark acceleration and the bike now pulls 100mph in 2nd but
The bike is soooooo much quieter & smoother when you're stuck cruising at 50mph+ in top gear
I just ride the twisties in 2nd / 3rd instead of 4th / 5th
It is still happy trundling along the flat at 30mph in top
I've had over 200 miles on a tankful though that was 40 miles with the light on! In Scotland with no fuel for miles, scary! Still only put 16.5 litres in when I found an open garage.
Overall, a small loss of off the mark acceleration but a massive improvement when just cruising and fuel economy.
