That's funny...I get a lot of compliments/comments from Harley riders for the TB. I rode the TBird to Deals Gap last year and had many compliments from HD riders. What was funny is they ALL had a story (virtually the same one) from their past about a Bonnie they used to have and were more than happy to share it. I'll admit there have been the ones (but only a few) that just bestow "tolerance" for the Triumph. As one guy put it, "I can tolerate Triumph...at least GB was an ally." I will, however, say that even though I get a lot of compliments on my Kawasaki C14 also, it's never from the Harley crowd.
Older Harley guys that remember Triumph from the 50's through the 70's are more likely to pay their complements. It is the younger Harley riders that typically snub me.
