Hey Keith & Graeme, After first reading the post I thought this was the way I would like to go.
On second thoughts I am not to sure.

With wearing a full face helmet I find I have to really bend my head forwards to read my tacho, this is my main concern. When riding around town here the boys in blue are very keen and it would be a PITA having to keep looking down at the speedo all the time and not look at the road.. All I have to do now is move my eyes and I can see the road as well as the speedo.
Do you 2 guys have that problem.
