Although bereft of the mandatory Inazuma! Venison sausages are my preference, or good Kent pork and sage bangers a close second!

I'd suggest Avon RoadRiders. On Fleabay a 110/80ZR17 can be purchased for £104-00 and a 140/70ZR17 for £153-00. They have performed well on the Honda Bros and SRX's for years. Kat has managed to squeeze 6,000 miles from a rear and 12,000 miles from a front on the Bros 400.
As for the quotation
I'm going to have a bit of a think about what to do, especially as my local bike shop quoted me £300 to supply and fit a pair of Bridgestones

"Highland dancer!" and a swift exit left would be my immediate reaction.
However, because Ukraine was the world supplier of carbon black and this is a major constituent of tyre rubber, the price for this raw material has gone through the roof! Hence, silly money for tyres!

Greasy, Indian Rubber Company tyres would not be my immediate choice of tyre.
Good health, Bill
