Ultima Cycles bike in a box. Started with their kit, but everything on bike has been improved with custom work. 113ci S&S cylinders. 42cc Jukini Flat side carburetor. Custom tank holds 6 gallons. Paint and Powder coat on frame is less than year old. Brake calipers from CBR1000R front and back. Chain final drive installed due to need since belts were failing. Great riding bike.
