Handlebars and Controls

For handlebar mountings and clamps click here. For cables click here.

1″ diameter handlebars were used up to 1946 but from 1939 some models used a handlebar with a 1″ diameter centre section reduced to 7/8″ diameter for the rest. All telescopic fork models have 7/8″ diameter handlebars.

Handlebars and Levers

The controls that are available are sold as suitable replacements and not as exact copies of the originals, however most are close and all will do the job. The application list below gives the part number(s) for the best available suitable replacements, for details see listing below. For total accuracy the owner’s guide, parts books and period catalogues should be referred to. For notes on the 1956-58 levers, see section 37. The 6400-39 handlebar was 1″ diameter in the centre to fit the existing bracket but tapered to 7/8″, we have not been able to get these made.
