ACCEPT THE CHALLENGE

with an

ALL-BRITISH MO-PED

(2 SPEED)

ON MODERN UP-TO-THE-MINUTE LINES!

The "Grey Wolf" is distinctive and eminently functional.

Clutch and 2-speed Gear runs at engine speeds, as in car practice, and in consequence is smaller and lighter than the usual half-speed motor cycle gearbox.

Location of power Unit below the road-wheel centres, and between the pedal cranks, ensures exceptionally good riding stability, yet with ample ground clearance.

All specifications and prices are subject to alteration without notice.

ENGINE.

49 c.c. Two-stroke Engine, bore 42 m.m., stroke 35.5 m.m. An "oversquare" engine on the most modern lines with ample port areas laid out particularly for good pulling power at average speeds.

The cylinder is of cast iron with adequate finning, held down to the aluminium crankcase by four long studs. These also secure the aluminium alloy Head, which is generously finned and carries the 14 m.m. Sparking Plug at the most effective position in the machined spherical combustion chamber.

The Piston is in LO.EX aluminium and carries two narrow rings and the circlipsecured gudgeon pin.

The connecting rod is a high-tensile steel stamping hardened and ground in the bigend eye, and running on 2.5 m.m. diameter rollers on the sturdy crank-pin.

M1b   

The crankshaft runs on extra large ball bearings. Oil seals are provided at each end of the crankshaft.

GEARBOX.

The Gearbox, - a separate item - is bolted up to the engine to form one compact Unit. It contains a multidisc clutch and two-speed gear operated by handlebar twist-grip and clutch lever combined. A short enclosed shaft conveys the power from engine to clutch and gearbox. Spiral bevel gears transmit the drive to a short cross shaft carrying the sprocket for the final drive by 1/2" P.X. 3/16" Chain to the rear wheel. Thus there is only one chain in the power drive and the whole transmission is exceptionally neat and compact.

Gear ratios, Top 13-8 to I. Bottom 22-7 to I.

FRAME.

On modern lines, built up of two immensely strong taper-drawn " D" Section Tubes running from steering head to rear wheel axle. Seat tube supported on symmetrical pressings mounted upon these main members.

Pedal bracket height is the normal 10" with 5 1/2" cranks, giving good ground clearance. The pedal cranks are straight and unusually narrow for this type of machine.

This frame is equally suitable for gents or ladies, having an " open "section slightly lower than a normal lady's cycle.

FRONT FORKS.

This important item is based upon the most modern bottom leading-link type. The suspension units are of bonded rubber completely enclosed, the two substantial bearings being shrouded within the rubber. There is nothing to go wrong, yet everything is easily accessible. The rubber units have a natural selfdamping effect eliminating excessive movement.

A separate torque-link for the front brake is a refinement which avoids any disconcerting rise or fall of the front part of the machine when the brake is applied or released.

TYRES.

Latest Dunlop, 23"X2", giving a compact appearance and a low saddle position when required.

RIMS & SPOKES.

Chromium plated Westwood rims and heavy gauge rustless spokes.

HUBS & BRAKES.

Both brakes are of the internal expanding type of ample size. The rear brake is operated by back-pedalling as in the normal coaster hub, but the mechanism actuates expanding shoes of 4 1/4" diameter. The roller-type free-wheel is completely enclosed and lubricated within the hub.

The rear hub is of the modern large-centre easy-clean type.

M1c       

MUDGUARDS.

Deep half-round section, 3" wide for good weather protection.

HANDLEBAR.

Raised, well-angled type giving a natural grip and adjustable for height.

SADDLE.

Oversize mattress-top saddle for easy, comfortable riding, adjustable for height and angle.

STAND.

Central spring-up Stand - light, strong and easy to operate.

CARRIER.

A sturdy rear Carrier is provided for parcel and luggage transport.

FUEL TANK.

The fuel Tank, of compact and pleasing appearance, is of unusually generous capacity. In addition to a useful reserve, a full gallon of petrol and its appropriate quantity of lubricating oil can be taken without over-spill. This will be appreciated by those who have been limited to half-gallon supplies. Tank capacity 1 1/4 gallons.

SILENCER.

The exhaust system has received particular attention and the Silencer is large enough to ensure quiet, refined running without back-pressure. Easy dismantling for internal cleaning is a special feature.

CARBURETTOR.

A special Amal type 360/4 Carburettor, with easy starting device and Twist-grip throttle control is fitted.

IGNITION & LIGHTING.

A Miller Flywheel Magneto, with Lighting Coils, provides ignition and lighting in conjunction with adequate Head and Tail Lamps, and a 14 m/ m Sparking Plug.

The Electric Horn is energised from the flywheel magneto.

SPEEDOMETER.

The Speedometer-an optional extrais front-wheel driven by very neat enclosed gearing. The dial head is incorporated in the Headlamp, (dial illuminated at night), eliminating all untidy external fittings.

TOOLBOX.

A sturdy metal toolcase capable of carrying more than averagesized tools is fitted between seat-tube and mudguard. Tools, tyre-pump, licence-holder and numberplates provided.

HERCULES

Introduced last year under another name, the Her-cu-motor Mk. 2 has been joined by a cheaper version designated Her-cu-motor Mk. 1. The new model utilizes the same 49 c.c. two-stroke as that fitted to the Mk. 2.

The power unit is unusual in that the crank-shaft is in line with the frame longitudinal axis and there is shaft primary drive to the two-speed gear box. The frame of the newcomer is similar to that of a lady's cycle but with header-gauge tubing.

Up-to-the-minute ! De-luxe! Fully Equipped!

Abreast and ahead of the most modern moped design and practice, CORVETTE claims your special attention because it is powered by the famous and well-proven Lavalette Engine with unique Automatic Clutch.

CORVETTE is the ultimate in personal powered transport. It is not only a NEW moped. It is a NEW conception of mopeds which Hercules, with the widest National and International resources to call upon, are now in a position to market.

COMPACT DESIGN combines clean lines with functional practical advantages.

APPEARANCE is outstandingly pleasing, enhanced by ample Fairings giving an unusual degree of enclosure of power unit, transmissions and rear wheel. This enclosure, together with generous mud-guarding, gives maximum protection from dirt and oil with resultant personal advantages to the rider as regards cleanliness of clothing and hands. This is important in these days when personal appearance is rated highly by moped riders, especially the Ladies. Important as appearance may be - whether of rider or machine the question of

PERFORMANCE and EASE OF CONTROL must be paramount. It is in these respects that CORVETTE has unequalled advantages - see specification.

Out of the Blue comes

"Mademoiselle Corvette"

Continental flair PLUS first-class British Workmanship.

SPECIFICATION

ENGINE-49 c.c. LAVALETTE engine (single speed)

with AUTOMATIC CLUTCH.

Hundreds of thousands have been proved in road service

to be highly efficient and reliable. The engine runs on a

20 to 1 mixture of commercial-grade petrol and oil.

Consumption is approximately 150/160 m.p.g. in normal

circumstances.

Vital feature is the Automatic Clutch, which progressively

engages when accelerating, and dis-engages when the

engine is running at slow speed.

This dispenses entirely with manual clutch manipulation,

the sole control being by the throttle. This leaves the

left-hand free to operate the rear brake.

The Automatic Clutch greatly simplifies the operation of

the moped, both for experienced riders and particularly

for beginners.

The CORVETTE can be kick-started on its stand. There-

fore initial pedalling is not essential.

By a simple ingenious device, the pedalling action can be

freed from the engine drag in case of difficulty, and the

machine used as a pedal bicycle with greater ease than is

customary with mopeds.

FRAME - In accordance with finest moped engineering

practice. Heavy gauge tubing.

WHEELS - 23"x2", giving low centre of gravity for

safe roadholding.

TELESCOPIC FRONT FORKS-Providing smooth,

comfortable riding and giving greater stability of steering

and better road-holding than any other type.

BRAKES - Exceptionally efficient hand-operated 3 1/2

internal expanding Hub Brakes, front and rear.

HANDLEBAR - Notably " clean " appearance achieved

by means of 2-bolt attachment directly to top of tele-

scopic front members.

PETROL TANK - 1 1/4 gallons, simplifying replenishment

at Filling Stations.

POWERFUL LAMPS - Head Lamp, and Tail Lamp

incorporating Prismatic Reflector for safety.

EQUIPMENT - FOOT PUMP, Electric Horn, Centre

Stand, Rear Carrier. Saddle Bag and Tools. Number Plate,

Licence Holder.

FINISH - Delightful Two-Tone contrasting pastel shades.

Silver Birch Grey for Frame and Forks ; Wedgewood

Blue for Fairings and Guards. The Upper Engine Fairings

are in polished Aluminium.

SERVICING Whilst the CORVETTE in itself is an

exciting newcomer, it embodies the already highly-

proved Lavalette Engine Unit. Servicing requirements

may therefore be expected to be at a minimum, but a

well-equipped Servicing and Spare Parts Organization

will be at the disposal of Owners.
