I would kick the Buell down the road before I kicked any of the others. Then again I have owned a Buell........
There's something I like about the looks of them. But I did a tour with an idiot who had one...Lightning with 1200cc engine or something. He was Harley trash at heart but couldn't afford a Harley so he bought the Buell, did a hideous job of murdering it out, took off the pipes so it was DISGUSTINGLY loud, and we had to stop every 100 miles or so to fix something with it. D***head still owes me money but I never want to see him or his bike again. He soured me on Buell's quite a bit.
*edit, just so no one's offended: by Harley trash I mean a poser POS who knew nothing about bikes but wanted to be seen on one. Religious nutjob with bad hygiene also.
