Nice ride there bloke, tyre where well from experience and every body will tell you the same the weight and style of the bike dictates tyre were a lot especially the camber on our roads.
I think I was lucky got over 18,000ks out of the back Metzler and around 20,000 from the front but had the same wear pattern on both the right hand side.
will be trying the exedra rear next time and now have a dunlop on the front handles quite well, but stress the point enough keep your tyre pressures spot on. I run 42psi in front and rear at all times and check it every week. I have noticed the front tyre loses pressure if not ridden for a week but when riding regularly holds pressure well.
A few of the boys here will like the fact you got a red one lol.
