There are some fascinatingly engineered Vincent racers, Matson, Chapman, Brown, Higgins, etc, but Marty's Blue Bike has a simple elegance that equals its fantastic performance (given the restrictions of the class it competed in). You really have to see the bike in person to see the numerous custom details he incorporated. He trimmed the bottom section of the petrol tank, the shafts on the Girdraulics have custom machined rounded heads on one side, all large diameter bolts have a taper cut into the end, the castings on the RFM are ground down to smoothly blend into the tubes, the way the handlebar mounts are rotated down, and the curves of the resulting handlebar to snake its way through the inside of the parallelogram of the forks, the rear sets way back at the rear wheel and how the brake lever pivots right off the actuator in the brake plate. Plus the fully polished cases, chrome and paint work show quality, despite the ravages of salt. Beautiful.
