Electronic speedometer pick-up from gearbox front sprocket?

[John Kat]

I believe the GSXR 1000's from 2003/4 used a hall sensor pick-up located in the engine sprocket cover?
Can anyone confirm if this is correct and better, send a few pictures to see how it is done?
The purpose would of course be to use a modern speedometer like the one used on this GSXR model : http://www.cmsnl.com/suzuki-gsx-r1000z-2003-2004-usa_model16069/partslist/98719.html#results
Beyond that it would greatly facilitate the use of 18" GSXR first gen front wheels in the GS 1000 OEM forks.
Fitting the speedometer pick-up should be easy with a racing type sprocket cover as fitted on my GS 1000 ST

Some of the Bandit 1200's used them as well. Not sure of the years - I think it was the 2nd generation (pre water-cooled).
