I've had more Yamahas than anything else (about 14, v's 6 or 7 Hondas, 3 Beemers and fewer than that of several other makes) but the brand has NOTHING to do with it. I have bought bikes that interested me, met my needs/wants and were at the right price. The only one I ever specifically sought out was the GTS1000. It does just happen to be a Yamaha but that was not why I bought it. My BMWs are probably my favorite bikes - but I have no real loyalty to the roundel and that's not why I bought them. I'd like to have a Triumph - but it would have to be the right bike, at the right time and the right price.
I guess I might be a teeny bit of a reverse snob for H-D but that has more to do with the "culture" crap that goes along with it, not the brand itself.
With the exception of HD, the worst offenders I have come across lately have been the KTM "Orange Kool-ade" crew. I now await the barrage of "You don't understand - they are just better than everything else!"
