Have a look at the E07
129/80 18 clears the swing arm on R65s and R100 fat swing arm so should fit R75
100/90 19 is not a fat tyre and has a moderately steep Crown Radius Section so your fine control and tip in is not compromised.
TKC hook up on the edges better on loose surfaces once you start power sliding and are better but not great in muddy conditions.
The E07 will outlast the TKC are cheaper and handle much better on the road especially in wet conditions.
It's also much quieter on the road, TKCs are almost as loud as a full knobby
