this seems to be a nice summary of what's available complete with compound designation and recommended rim size, though the 170 rear rim size recommendation is probably a typo (5.50 instead of 4.50). bit surprised at their pressure recommendations for the front tyre, 30 psi cold....
for the front you only seem to have one size option and as far as I know dunlop doesn't supply pre cut slicks. they do come with markings that make it easier to cut your own pattern.
like I said, I bet that's a typo and should really read 5.50, easy mistake. no way is that 170 gonne sit right on a 4.50 rim.
I have a 165 dunlop laying around but have yet to mount it... running a 5 inch rear as well. KTM did supply the smr range with 165 rear slicks for quite some time and all those bikes had 5 inch rear rims, if I had to make a guess I think it won't be that far off.
I've only ever seen the 170's on a 5" until recently. When they're put on a 5.5 like I just saw recently, they look sort of triangulated. Kinda flat sides, less of a lean angle, and If I remember right the tire was sort of stretched so one side was more flat than the other
