Managed to fit my snooper s4 today, not easy as like you say no room! My R1 has very screen/clocks room in the first place but to be honest it fits quite well.
The unit is on the screen just above the tacho and the laser unit is on the inside of the faring adjasent to the fork leg.
I was informed that the one to go for was the S4 because the previous s6 kept giving faulse allarms!
Which snooper did you have lads, please dont say 'THE S4R!!'
