Just had the metzeler M5's fitted by HM Racing and first impressions over 200 miles are very positive, for medium to fast road riding. Very stable, don't seem to move at all, and very confidence inspiring . Almost at the edge of the tyre, and have been riding a little more cautiously than normal as I get used to them.
Looking at the groove pattern I am sure they will be great in the wet, especially over the K3 which were pretty hopeless (although not designed for the wet, to be fair)
The biggest difference over the K3 though, is bike comfort. It's night and day, from feeling every bump and very twitchy, to a real magic carpet feeling over bumps and ruts. For those of you who have not ridden in East Sussex this is very important, lol!! Usually there is a trade off for performance , but so far so good.
Off to Normandy for 4 days in a few weeks so they will get a full test then .
