Overall, though, if the only things we could find to complain about are the higher-speed engine vibration and the fuel tank’s reserve capacity, the Custom must be one excellent Sportster. And it is. It takes everything that’s been good with Sportsters for more than 40 years and enhances those qualities, while minimizing some of the continuing complaints. Vibration still remains an issue, of course, and will continue to do so until The Motor Company redesigns either the engine or the chassis. But over the years, gearing changes and some tweaks to the balance factor have continued to move the point of annoying buzzing higher, until this Sportster can cruise comfortably at legal highway speeds. So, in the areas of functional performance, it works better than any Sportster before it, with the exception of the 1200 Sport. And it looks cool as hell, too.
