Barney, I've ridden the Bonneville SE, and I have to say I thought it handled brilliantly. The 17inch wheels make a noticable difference in this regard as compared to the regular Bonneville or the T100.
I also have to say that at first I wasn't sure about the look of the new SE, as it looks more 1970s-style Triumph in appearance with the standard cast wheels(as compared to what some might call the more "classic" 1960s look of the standard Bonnie and T100), BUT the more I see of that blue and white SE, the more I'm REALLY diggin' it! Yep, I wouldn't mind havin' one of those babies myself, ESPECIALLY as I said, after I test rode one of 'em.
If you decide to purchase one, I can almost guarantee that you will NEVER suffer from "buyer's remorse" later on!
These modern Triumphs are as smooth-running, reliable, pretty much maintenance-free, fun to ride, AND as eye-catching as any make of machine out there on the road today!
(...and probably MORE than the rest of 'em too!)
