Went to Morocco and back on my GP450 - 5,000kms. Wet performance OK as long as you're sensible in bends. Dry performance is good. Back tyre half-worn, front still has the pimples. Had the back end break away once but that was a roundabout and I may have caught hot wet tar or fuel. Not great in soft sand, OK on piste (fire roads).
I'll fit a set to the Ten once the fitted tyres have worn out
