I feel your pain, but I back you 100% on this one, Robert.
A couple of months ago I bought an '84 Yamaha 650 Heritage Special, and riding it is one the the few times I wear...gasp...trousers. However, I WAS wearing my UK when I took it for a test ride.
Like you the main reason for buying this bike was to save a bit of money on my twice-daily commute into work. So far it's helped. I will be slowly restoring the bike, though.
