A box section Triton swinging arm manufactured by Dresda Autos to fit the Norton Featherbed frame - either wideline or slimline. The rear spindle is suitable for the standard Norton rear hub. A spacer tube is included to separate the 2 wheel bearings. The swinging arm is fitted with rear chain adjusters. It has taper roller bearings at the pivot point on the swinging arm. The finish is stove enamelled black. The swinging arm is suitable for use with a pre-unit or unit Triumph engine. The box section swinging arm is wider than the standard featherbed swinging arm and can therefore accommodate a wider back tyre.nnThe wheel end of the fork has an internal width of 8 inches.
