I wore my UK the day I picked up the Yamaha 650 (metric Triumph, LOL) that I bought last year. As long as you tuck the front apron under a wee bit it won't blow around. If it's a warm day I may ride my Sportster kilted across the city to the Highland Games in Sept.

As for RAT...I'd never heard of them until this thread! While I don't own a Triumph now, I used to have a number of them, all chopped. Maybe I'll get another one someday, they sure were a blact to build and ride!
This is all I have left to remind me of those days...
