Time For A Gearing Change ?

[spike240]

Hi - reading through this thread, as sometime in future I am thinking of a 15 tooth front sprocket. A friend reckons it will make the 900 more useable. A couple of questions - someone said the speedo  error wouldn't affect the ABS models - why is this?

And Lodger -  did you end up swapping cogs? If so - what do you think? And where did you source the sprocket - oh and what make is it?

Many thanks.

PS The TDM is growing on me - I am learning how to ride it.
