Ok, I checked with the local tyre guy (Fred),
Metzler Z6 (the MEZ4 replacement - what I have now) $289.00
Bridgestone BT54 (yuck! I don't like Bridgestone, even on cars) $240.00
Michellin Macadam 100X $259.00
I asked him about the Shinko's and he said that he used to sell around 100 of them a year, but a couple of years ago he had two sets in a row that 'failed' (side wall ripped open) and the original importer went broke he hasn't sold one since....
If they don't make it in the 180/55 sizing then I'm not mucking around with different profiles.
Now, bearing in mind this is for the rear, I'm sorely tempted to go back to the Macadam. I know I can get 12,000km out of it easy, and I never had an issue with the rear. In fact when I mentioned the Macadam to Fred, he said he'd never put a Macadam on the front of ANY bike - that is unless he really hated the guy. He recommends the Macadam on the rear with either the Pilot Sport or Pilot Road on the front.
Anyway, now I have a rough idea of much it's going to cost I can start saving my pennies - shouldn't take to long I'm trying to quit smoking. I've only had 5 or 6 since last Friday which, considering I was smoking 15-20 a day, I think is pretty good.
