Our local motorcycle tyre shop stocks Motoz and our riding group have used a lot of the different ones. (501, 690, 790, 890, 900RallyPro, MTS950, 1290S) I think the consensus is : last a long time, look cool, the knobbier ones can give a fair bit of road noise, esp when over half worn and the hard compound 'may' not be as grippy on wet and cold roads... Overall quite positive.
