Hi lads. I bought my 2013 F800Gs in April this year and it came fitted with k60's and me being used to this type of tyres I've found them pretty good
but recently after close inspection I've found the rear one having quite few little hairline splits here and there, which worried me as I'm planning little tour this summer. So decided to replace it "for peace of mind" ... Bought brand new one from oponeo and paid £76 delivered which is pretty good IMO considering some sites sell them for £120+
delivery took less than 4 days so I'm pleased with that
