Metzeler's suck! Their standard street tire put on Katana's, SV's, and Triumph RS's are constantly getting complaints. The biggest one is heat up time. They have great life but you can't get the damn things warm enough to stick. At the shop I worked at we actually had one of the mechanics go down because of this. (No he wasn't showing off. He is not that type of rider. He owns a BMW R100RS with the entire hard luggage set all the time, if that tells you how conservative he is.) I have had rear sliding problems out of these tires and don't recommend them to anyone.
