Not many options where I live, within a 30 mile radius, last time I used a bike shop, I got seen off - £125 for a front Metzeler on my R1 @ Yamaha dealer!
With the Fazer, I bought a slightly worn front Diablo for £28 delivered and a new old stock Diablo Strada rear for £76 delivered and paid a mobile trye fitter £20 to fit the pair.
I take wheels off, he turns up, fits, new valves, balances all in 20 minutes, I re-fit and save a packet. Sorted.
If I could afford or want to spend / waste money on using a dealership to service my 10yr old bike and fit tyres, I would, but DIY as much as I can, just can't be arsed with the stress of changing tyres / scratching my rims at home (no garage either)
