I liked the Metzeler Block C for the slower bikes but for the speed rating the ME 77 is safer , an S type. Rear tires with 3.50-19 are hard to find with higher speed indexes so I think to have 18 inch types for the rear. So the ME 77 in 4.10-18 is available in H index - if not going for Bridgestone as many do ? But I like the more classic looks of the familiar Metzelers.
