Road King Custom upgraded with stage 1 kit
May 4, 2008
Our Harley-Davidson Road King Custom motorcycle has been upgraded with a stage 1 kit. This included the addition of D&D mufflers and Arlen Ness Big Sucker high flow air filter. The ignition was remapped by Harley-Davidson of Westminster to take advantage of the increased air flow. These modifications increased the horsepower of the big 96 ” engine by about 10%. The bike sounds great! The pipes look thin but amazingly give the bike a deep throaty rumble.
