I think it's the title, I read it as basically not UK bikes, and a cheeky Euro bikes are still allowed.
Possibly the use of non as that is just a missing hyphen from UK
I.e. it reads, non-UK and European bikes, to me.
I read it as Non UK and European, meaning nothing from UK or Europe,
Not that it matters as now it only has a couple of hours to go.
Hold onto those European and Italian/Mexican machines though as next month may just be another themed month as there must be a RBotM Brexit battle looming, thinking that it might be a European and UK only comp. What's peoples thoughts on that? Too soon?
