1975 Harley Shovelhead Bobber X-15
Kevin from Harrison Township, Michigan, United States made available these photos of this extreme Harley Shovelhead Bobber which he has named the X-15. Kevin makes a living designing and fabricating aftermarket parts and Harley Davidson motorcycle accessories through his company Fabricator Kevin's Steel Chopper Parts.
This custom bobber motorcycle started life as a 1975 74" FXE, and she was Kevin's 2006 contender for The Horse Backstreet Choppers magazine's Chop-Off contest, held at Smoke Out VII in Salisbury, North Carolina. This X-15 was chosen as the winning bike, and was featured on the cover of The Horse Magazine in December of 2006.
The X-15 bike took 7 months to build, and is loaded with specially made components: 7.5" dual disc front brakes, custom mid controls, clip-on handlebars, fully polished stainless steel seat, oil bag, fender struts and control levers. There are very few parts that aren't either hand-made, or highly modified.
The stock frame of this Harley Shovelhead was hardtailed, using axleplates that were salvaged from a 1950's Panhead frame. The front end is a Paughco vintage styled springer, and the chassis is powdercoated.
Dan Roedel completely rebuilt the shovelhead engine to be easy starting and reliable. The 74" motor received a .050" bore, and a new set of pistons to match. Kevin replaced anything that was out of spec. The motor was balanced and also features an Andrews A grind cam, S&S oil pump, and Manley valves, valve guides and springs.
The original 4 speed trans was also rebuilt, and it is connected to the motor via a Karata 1.5" belt drive. It is foot-clutched and hand shifted, and the controls were designed to be converted over to a hand-clutch foot-shift if desired.
Kevin's Shovelhead bobber has a springer fork with twin 7.5" disc brakes.
This Shovelhead engine breathes through two 34mm round slide Mikuni carburetors, which makes her very responsive. The polished rocker boxes were engraved by CJ Allan (engraver of Indian Larry's Chain of Mystery bike).
