I run the shinko's on my KLR250 & have been having an excellent run out of them doing road / gravel rides. Great on the road in the wet & really good in the dry. Mind you the KLR does not have the power to push them around.
Doing anything more than gravel requires a big drop in pressure from the road 24psi in the rear to a more offroad 12psi
The wife runs the IRC's on her KLR similar on road not as good on gravel but last longer, cost more tho, then I like sliding around a bit as well.
If you're not living on the edge you're not leaning over far enough
