Hi Tom,
I have thought about these however after talking to a chap who has tried them on his 1200 evidently they are good for 1 lap then just get too hot and go off very quickly.
Interestingly I googled the Yokohama A050 and believe it or not they make them in a 175x60x13 so I rang the importer here in NZ to see if they had/could get them only to be told that they were not bringing any 13" A050's into the country - even after offering to prepay for them. Typical NZ !
Well buggar them- I quickly had a look on the net and found a Japanese site that exports so will contact them for a quote.( and our retailers wonder why they are losing business hand over fist to overseas suppliers via the net!)
So a few options on the table- still waiting to hear on the Nankangs.
Watch this space!
Cheers
Dave
