We have Dunlop slicks on our CRF150R Supermoto (

He may try a different brand (not sure which) this season. I think there are only a couple choices in the small sizes we need.
I'll say that we have had numerous sets of Pirelli tires, both cycle (Ninja 250) and auto, and they all have dried and lost traction before they should have. I'm no longer buying any Pirelli tires.
