Time For A Gearing Change ?

[thelodger]

I am going to fit a new chain and sprocket . I haven't had my TDM 900 long but I did do a lot of miles over weekend and got the feeling that the bike would benefit from a change in the gearing so that it does more revs per mph .  This would help particularly in town riding when I seem to be in first most of the time and second would be better and also keep the revs out of the 3.5k to 4k zone more of the time.  I understand that standard gearing is 16 front and 42 rear . I am thinking of going 15 front . Has anyone else done this with positive results ?
