I’ve tried them on an Africa twin. Low road noise and surprisingly good grip, even on wet tarmac. No dramas at all and great grip on loose surfaces. Likely will struggle in thick mud but fine for most green landing. I bought the bike with them and didn’t expect much and was very pleasantly surprised. I’d recommend them.
If you fancy trying some Mitas Enduro Trail + tyres, I have a pair in great condition,3/4 worn at most, and in Himy sizes. 90/90 21 and 140/80 17. The rear is slightly narrower by number but not in practice due to the side knobs. It may reduce the gearing very slightly which is no bad thing if you are doing some off road stuff. They are going free gratis if you come and collect. Pictures attached.
