My rear tyre is buggered after 3800 miles as well as being punctured in the middle of France, but plenty of life left in the front. So I have replaced the rear only with a 023. Feels fine but only managed about 30 miles between showers yesterday so no where near scrubbed in yet.
The only motorbike tyre supplier and fitter near me in Macclesfield (as far as I am aware) was National Tyres and they now will not supply due to too tight margins therefore not worth the effort. However they still have the fitting equipment and will fit them for a small charge. I searched the internet and best I could come up with was Crossan Motorcycles in Northern Ireland. For the 023 they charged £121 and free delivery whereas most others were around £130 plus delivery.
