Relating bars and riding position etc to performance is only slightly ridiculous...we all know anyone buying a Bonneville for performace is in for a quick awakening and shouldn't waste their time unless they plan on spending several thousand dollars on motor components and shocks, new forks etc., oh yeah, and another front brake. Better to give up now - buy a Japanese-anything of equivalent capacity and blow Bonnevilles into the weeds all day long.
Personally I see both the low clip-on brigade (especially on the horsepower challenged Bonnie, much as I like it) as being just as image conscious as the ape hanger crowd. It's a lot of fun modding our bikes, but the best we can hope to do is make it less slow.
I must have missed something as I thought the original question was about slightly raised bars, not ape hangers, but anyway...
For what it is worth, my Flanders Vintage bars are a hair higher than Western bars though not wider, and they feel just about where the bars were on my previous original non-Hinckley Triumphs. DEFINITELY nothing like ape-hangers though.
I really enjoy my Bonneville, but I think I understand what it is, and what it isn't, and if one of our number likes higher bars, good luck to him... If this is the guy I think it is, he has just a little experience with some interesting machinery.
Just my two cents, and my flame suit is on
