D.O.T. Motors, Ltd., 69a, Market Street, Manchester.
Of the machines on the D.O.T. stand the model which will appeal instantly to riders of the sporting type is the 976 c.c. super-sports model, every line of which suggests speed. It is fitted with a J.A.P. P. engine, having side valves and heavily finned valve caps.
2½ H.P. Model.
70x76 mm. 292 c.c); single cyl. four-stroke; side valves; hand-pump lubrication; Amac carb.; chain-driven mag.; 3-sp. gear; clutch and kick-starter; chain and belt drive; 26x25/8in. tyres. Price, £65.
Other models are the 292 c.c. J.A.P.-engined standard and the T.T. types, the latter shown without a carrier and with the top tube concealed by the tank, wide handlebars with very effective rubber grips and single practical-looking footrests. It also has a J.A.P. engine of 70x76 mm. (292 c.c). A 250 c.c. model with a Blackburne overhead valve engine, and last, but not least, one of the new type machines having the 350. c.c. oil-cooled Bradshaw single-cylinder engine are also on view. This last is a new venture for the firm, and is of very neat design.
249 c.c., 348 c.c. and 976 c.c. Machines in Sporting and Touring Specifications.
UNDOUBTEDLY the must attractive models in next year's programme of Dot Motors, Ltd., are of the sports type.
One is equipped, with the 348 c.c. J. A. P. engine, and has all-chain drive through a three-.speed Albion gear box, giving ratios of 6, 7, and 11 to 1. No kick-starter is fitted as standard, but a clutch is incorporated.
Both brakes are of the internal expanding variety. The handle-bar is attached directly to the head, and both front brake and clutch are controlled by inverted levers. A carrier is not standardised; tyre size is 26 x 2 3/8in. and the price is £78; a 249 c.c. J. A. P. engine model may be had at £75, and other alternative engines are the 349 c.c. o.h.v Blackburne (£80) and 349 c.c. Bradshaw engine (£78). Next comes the big twin sports model with 976 c.c. J.A.P. engine and Sturmey gears of 3½, 5, and 8½ to 1 ratios. The general specification is similar to that of the lightweight model, with, of course, 28 x 3in. tyres and other fittings in proportion. The frame has duplex tubes under the tank, and sidecar lugs, while the handle-bars are adjustably mounted on the head-clip. This model is priced at £140. Large silencers are a feature of these sports models.
Touring Dot machines embodying engines of the similar capacities are also to be produced, the same general specifications being maintained. The touring 975 c.c. machine costs £105, and a suitable sidecar brings the total cost of the outfit up to £130.
The touring lightweight has the 292 c.c. J. A. P. engine with three-speed Albion gear and chain-cum- belt drive, and the price is the very moderate one of £55.
