i think it depends on what you want to do with your bike. race or street. for street i was very content with the stock mille and i'm thinking of buying another one just for street. mileage on mine was better than my rf 600r, 6 liters/100 kms at a cruise speed of 130-140 and an average speed of 100-110 outside the city, the sachs shocks feel better on the street/bumpy (not too bumpy though) roads than my ohlins and i feel it's more than enough for normal/sporty riding on the street.
