Hi Paul, I couldn't watch your youtube link when you first posted it (my rural internet connection couldn't cope) and I've just got round to watching it this morning.
Nice drive and a very pretty town, but, as you mention it above, what exactly is all that rattling and clonking?
I only ask because mine, Phil's and Barry's don't sound like that and I'm concerned something important might be loose.
I know it's early days and it was a shakedown run, but I'd advise you to check all your nuts and bolts are secure before your next run.
As for winter driving, so long as I'm wearing suitable clothing for the weather, the only bit of me that gets frozen is my face. I addressed that with a 'ped crash helmet from Caberg, open faced but with a full visor -
