Details of modifications and changes in specification

SEPT 1957


Publicity photo - click to enlargeP1 Scooter production started, ready for announcement in January 1958. It had an all-welded tubular frame of 2½" and 1¼" dia. tubes. Bodywork was glass fibre with a lockable container behind the steering head and detachable rear side panels for maintenance. The engine was the Villiers 31C, 148 cc with a 3 speed foot change gearbox, fan cooling and a 12 volt Siba Dynastart electric starter. Suspension on the front leading arm and rear trailing arm was by Armstrong coil spring units, hydraulically damped. Rear chain adjustment was carried out by means of an eccentric spindle through the rear trailing arm. Wheels were 10" on 4" section tyres with 5" brakes. A dual seat, hinged on the right hand side, revealed the fuel filler cap to the 2¼ gallon glass fibre fuel tank.
Overall length 7' 8", width 2' 4", saddle height 2' 4" and ground clearance 5½". The Wheelbase was 4' 4" and the weight 262 lb.

Colours available: Two-tone Blue, Green and Fawn or Maroon and Fawn. Optional extras included a windscreen, spare wheel and tyre, luggage carrier and a waterproof cover. Price was £184 12s 6d (£184.62½p).

JUN 1958


The P2 Scooter was introduced. Identical to the P1 except that it used the Villiers 9E, 197 cc engine with a 4 speed foot change gearbox, fan cooling and a Siba Dynastart. Weight 272 lb. Price £199 12s 0d (£199.60p).

SEPT 1958


Design changes to the P2: Front mudguards were painted two-tone, a lifting handle was fitted to the rear body and the rear brake pedal was redesigned to be toe operated instead of heel operated. A new type of handlebar cowl was introduced, a moulded mat replaced the plastic strips on the footboard and the handlebar control cables were enclosed in rubber tubes.

SEPT 1958


The P2 design changes were incorporated into the P1.

OCT 1959


Glass’s Motorcycle Check Book lists this frame number but gives a date of June for the last P2 produced. It is highly likely that the frame number is correct, as the coding system used follows previous known modifications. The June date, however, has been ignored.

OCT 1959


The last P1 produced? The explanation is the same as for the P2.

SEPT 1959


Publicity photo - click to enlargeThe P3 (148 cc) and P4 (197 cc) production started ready for the October announcement. Generally the same specifications as the previous Scooters but with the following changes: A redesigned front bodywork which also included the mudguard, the lockable front container was deleted and the rear bodywork was made as a complete one-piece moulding hinged at the rear. The steering head angle was altered and the engine unit lowered 2¼" to improve handling. Other changes included the deletion of the chain guard, the fuel tank was made in steel whilst aluminium styling flashes decorated the sides of the rear bodywork.
Overall length was reduced to 7' 3" with a shorter wheelbase of 4' 2" and a ground clearance increased to 7". Weight was reduced to (P3) 252 1b and (P4) 264 1b.
Colours available: Red/Fawn and Dark Green /Fawn. The P3 was priced at £178 10s 6d (£178.52½p) with the P4 at £193 0s 0d (£193.00p).

FEB 1960


Improvements to rear braking included a new foot brake pedal, rear cable, drop arm and operating arm. Different O/S and N/S front engine mounting plates were also fitted.

MAY 1960


A new handlebar assembly was introduced. One of the improvements was a locknut on the twist grip adjuster screw!

JUL 1960


A new light switch was fitted.

AUG 1960


The last P4 produced. Again, this frame number is taken from Glass’s Motorcycle Check Book but the final year is listed as 1962. This has been dismissed as wrong because it would have meant that just under 400 scooters were produced in a three year production run, i.e. less than 2½ per week!

AUG 1960


The last P3 produced.
