496 c.c. P.V. de luxe 1923

Moderately Priced Fully-sprung Solo Mounts.

FOR next year the P.V. programme includes three popular models, fitted with a 250 c.c. Villiers two-stroke, a 350 c.c. Villiers two-stroke, and a 293 c.c. J.A.P. four-stroke. All are equipped with the simple P.V. spring frame, which is extremely satisfactory, having stood the test of time, and with a Burman two-speed gear, clutch, and kick-starter. The prices are : 250 c.c., £50; 350 c.c., £ 56; and 293 c.c. four- stroke, £60. Any one of these models can be supplied with a plain two-speed at £4 less or with a three-speed gear and kick-starter at £4 extra.

Next there are the de luxe models, of which the 350 c.c. model with B. & S. sleeve-valve engine and Burman three-speed gear is extremely attractive. It can, however, be had with a 349 c.c. J.A.P. four- stroke engine if desired.

In these de luxe models the spring frame has been slightly modified, as the saddle tube containing the springs suspending the rear portion has been placed forward of the gear box, consequently shortening the wheelbase considerably.

Not only is there a Brampton spring chain fitted, but there is a shock-absorber in the Burman clutch. This, coupled with the spring frame, renders the machine extremely smooth, and the same method of transmission is employed in all three models, which have many details in common; for example, the excellent brake system, consisting of large shoes applied to dummy belt rims. It is also worth noting that customers are given a choice of carburetters.

Another interesting fitment which is supplied as a standard to these last three models is the jackstand, which enables the machines to be jacked up with the minimum amount of effort, permits of easier access to the back tyre, and absolute rigidity when the back wheel is raised off the ground. Front stands are supplied to all these models, and an ingenious and absolutely, secure form of stand clip which cannot rattle.

Prices of the de luxe models are : 350 c.c. with J.A.P. or B. & S. engine, all-chain drive, £76; 495 c.c. twin-cylinder J.A.P., £90, or with J.A.P. super-sports engine £95; the de luxe sidecar model. 654 c.c. twin-cylinder J.A.P., all-chain drive, £122.

The well-tested P.V. spring frame has been incorporated in the sidecar wheel most successfully, and the sidecar is undoubtedly one of the best sprung attachments obtainable.

That it has survived so many years successfully when other systems appear and disappear in the course of a twelve-month proves that the P.V. spring frame is worth while. It is a simple design. Two pivoted arms, which carry the rear wheel, are extended to the saddle tube and connected with coil shock and rebound springs enclosed in the last-mentioned member.

For 1923 the wheelbase has been considerably shortened by the simple expedient of moving the saddle tube forward so that its lower end is in front of the bottom bracket.

The model at present under discussion is essentially a solo machine and is also shown with a super-sports J.A.P. engine of the same size and a T.T. specification, when it costs £95.

Essentially the same as the 498 c.c. touring model is the 654 c.c. sidecar outfit, the chassis of which embodies a spring wheel suspended on exactly the same system as the cycle. The body is further insulated by two pairs of flexible C springs, underslung in front.

Detail work is well carried out. Braking is on dummy belt rims front and rear, front stands with neat clips are fitted in each case, and the Jackstand, an easy action two-step device introduced at the last Show, is embodied on the touring machines.

Also on the same lines is an entirely new model with the 976 c.c. J.A.P. engine. It is priced at £145 solo, and £167 with the P.V. sidecar. A B.T.H. mag-generator costs £17 extra.

One of the P.V. lightweights to which a 349 c.c. Barr and Stroud engine is fitted follows the same specification, when the price is £76, but the remaining Villiers- and J.A.P.-engined machines, all under 350 c.c, have final belt drive and cost from £42 upwards.
