MADE LIKE A BULLET
Royal Enfield was the brand of the Enfield Cycle Company.In 1955 they started assembling bullet motorcycles at Enfield India under the UK license, and by 1962 they started manufacturing complete bikes.
The original Redditch, Worcestershire based company dissolved in 1970, but Enfield of India, based in Chennai, continued, and bought the rights to the Royal Enfield name in 1995.
The first automotive vehicles with the Royal Enfield name were produced in 1898 - a quadricycle with a De Dion-Bouton 2.75 hp engine.In 1901 came the Motor Bicycle with a 150 cc 1.5 hp (1 kW) engine above the front wheel.
1921 Royal Enfield V Twin, 1000cc
In 1910 came the first of the famous Enfield V-twins, first with Motosacoche 344 cc 2.75 hp (2 kW) engines, later with Enfield's own engine. Until World War I the big twins with 770 cc six hp J.A.P. engines and after WWI 976 cc eight hp Vickers-Wolseley engines. In 1915 came the first of the small two stroke 225 cc engines, starting with model 200.
During World War II, The Enfield Cycle Company was called upon by the British authorities to develop and manufacture military motorcycles. The models produced for the military were the WD/C 350 cc sidevalve, WD/CO 350 cc OHV, WD/D 250 cc SV, WD/G 350 cc OHV and WD/L 570 cc SV. The most well known offering beyond doubt was the Flying Flea aka the Airborne. This lightweight 125cc bike could be dropped by parachute along with airborne troops. The factory also manufactured a variety of special instruments and apparatuses to use against enemy forces during war. In 1931, a four-valve, single-cylinder was introduced and christened "Bullet" in 1932. It had an inclined engine and an exposed valve gear. It was the very first use of the now famous Bullet name.
The 1939 Bullet 350 kick started the post-war models. They used two rocker boxes for the first time. This enabled better gas flow and consequently higher volumetric efficiency. Royal Enfield's own designed and manufacture telescopic front fork placed the Redditch marque at the very forefront of motorcycle design. The biggest advancement introduced by the new Bullet was its swinging arm rear suspension system and hydraulic damper units themselves. In 1949 Enfield made a J2-the first model with a telescopic front end followed in 1948 by a 500 cc twin.
The 500 cc Bullet engine produced 25 bhp (19 kW) at 5,250 rpm while torque peaked at 29 lb·ft (39 N·m) @ 3,600 rpm, From 2,000 rpm onwards torque did not fall below 25 lb·ft (34 N·m) till beyond 5,300 rpm. Later models like the 250 cc Crusader (1957) and 700 cc Meteor (1955), were followed by the 250 cc Continental GT (1965), the 700 Constellation (1959), available with Royal Enfield's "Airflow" full fairing, and the 736 cc Interceptor (1963).
In the late 1950s and early 1960s, Royal Enfield produced a number of 250cc machines. The biggest selling of these was the Royal Enfield Crusader, a 248 cc pushrod OHV single producing 18 bhp. In 1965 a 21 bhp variant called the GT Continental, with GRP tank, 5 speed gearbox , clip-on handlebars and rearset footrests was launched. It sold well. Other variants were the 250 "Turbo Twin" fitted with the Villiers 247 twin two-stroke engine. An oddity was the 250 Clipper, mainly notable for its use of trailing-link front suspension (all the other 250s had conventional telescopic forks).
AN OLD BULLET AD FROM INDIA
THE PRESENT AGE
In 1955 the Redditch company partnered Madras Motors in India in forming 'Enfield India' to assemble, under licence, the 350 cc Royal Enfield Bullet motorcycle in Chennai. The first machines were assembled entirely from components shipped from England, but by 1962 all components were made in India. The Indian Enfield uses the 1960 engine (with metric bearing sizes), in the pre-56 design frame.
An independent manufacturer since the demise of Royal Enfield in England, Enfield India still makes an essentially similar bike in 350 cc and 500 cc forms today, along with several different models for different market segments.
In 1994 Eicher Group bought into Enfield India. In late 1995, the Enfield India firm acquired the rights to the name Royal Enfield. Royal Enfield of India now sells motorcycles in over twenty countries.

The 2006 ROYAL ENFIELD BULLET 500
THE CARBERRY-ENFIELD 1000cc V-TWIN ENGINE
A BULLET WITH A TWIST - THE CARBERRY ENFIELD
The concept of the Carberry-Enfield was conceived by Paul Carberry and brought to fruition by Paul and Ian Drysdale (Of the Drysdale 750-V8 and 1000-V8 fame). The basic premise was to create a “classic” style 1000cc British V-Twin utilising as many standard Royal Enfield parts as possible. All this to attain a well mannered torquey cruiser with the look, feel and sound expected from a bike with traditional British bloodlines but with enough technology to make it a practical every day workhorse - at a reasonable price. The design premise included keeping production and maintenance costs down with a worldwide availability of spare parts. The 55 degree vee angle was chosen for the combination of style, balance and mechanical simplicity. One consideration was to allow the hydraulic lifters to be accommodated above the standard Royal Enfield cams without modification to the barrels. Any vee angle tighter than 55 deg also requires heavy modification of the Royal Enfield heads for carburettor clearance. The standard Enfield primary drive cover has also been retained . The Enfield clutch is “beefed up” and a bigger engine sprocket is fitted to utilise the extra performance of the V-twin.

EVERYONE MAKES WAY FOR THE BULLET
YET ANOTHER ROCKING BULLET AD
THE DIESEL BULLET
THE DIESEL VARIANT OF THE GIANT
Two different power options are available based on the Greaves diesel motor, the kind of engine more likely to be seen powering a cement mixer on a third world building site. The first option is the 325cc, 6.5hp at 3600rpm unit which is kickstart and not too happily married to the standard four-speed gearbox. This has the benefit of being easier to kickstart but has a very low cruising speed of 40mph.
Then there is the 'deluxe' model fitted with the larger whopping 436cc engine with 5-speed gearbox that puts out a heady 7.5hp and which has a maximum speed of just 55mph.
Engine:436cc or 325 cc Greaves
Transmission: Manual, 5-speed or 4 speed.
Fuel Tank Capacity: 14.25 litres.
Fuel Efficiency: 40 kmpl.

THE CARBERRY BULLET 1000cc IN ACTION
A TURN TO THE GREEN SIDE
In 2006 Royal Enfield released a 'lean burn' engine incorporating a new cylinder head and piston, alloy barrel, gear oil pump and roller big end bearing. Lean burn refers to the use of lean mixtures in an internal combustion engine. The air-fuel ratios can be as high as 65:1, so the mixture has considerably less fuel in comparison to the stoichiometric combustion ratio.
After five years of research and development, Royal Enfield, unveiled a new engine platform called the Unit Construction Engine (UCE) . To be available in 350cc and 500cc models, the new platform will replace the Lean Burn Engine.The new engine makes its debut in the Thunderbird Twinspark 350cc. The engine includes an Integrated gearbox too.
The 500cc variant, which is Euro III compliant and has Electronic Fuel Injection (EFI) technology, has been fitted in the Bullet Electra and would be exported to countries in US, Japan, UK and Europe and will not be available in India for the time being.
THE NEW FUEL INJECTION ENGINE
THE FUEL INJECTION UCE ENGINE
Royal Enfield unveiled the first product of its next generation engine. The 500cc UCE (Unit Constructed Engine) or integrated gearbox engine is equipped with Fuel Injection technology. The 500cc EFI will first feature in Royal Enfield Electra. The 500cc UCE still features pushrod operation of the two valves per cylinder but is otherwise very modern, with roller hydraulic lifters, crossover gearbox, and a gerotor oil pump. With the introduction of new bullet engine, royal enfield, signalled its decision to phase out older iron cast engines. In England, France and other european countries, the classic iron blocked, four speed bullet will be on sale until the end of 2008. From 2009 onwards all Bullets will be powered by unit construction electronic fuel injection (Euro III complyable) engine.
THUNDERBIRD TWINSPARK WITH THE NEW UCE ENGINE AND INTEGRATED GEARBOX
The new Thunderbird Twinspark comes with modified UCE engine with an integrated gearbox which now puts out 10% more power and torque as compared to the earlier engine. It is the same Thunderbird in design and styling. Just two twinspark badges on the side flanks and a twinspark decal on the rear side are added. The new integrated engine in the Thunderbird Twinspark employs six clutch plates for reduced clutch lever effort and hence strain free riding. This new set up results in lesser parts and hence lesser friction. The main architecture of this engine is developed in-house by Royal Enfoeld while NVH & internal combustion of the engine is tested by European design consultants.With the UCE, Royal Enfield wishes to improve the reliability & reduce the manual intervention needed for smooth functioning of the engine. The valve clearance of this UCE adjust automatically through the use hydraulic pushrods and thus the vehicle maintains optimal valve timing in all situations.Another notable feature in the new Thunderbird Twinspark is the auto decompressor. The slide switch is gone. The auto decompressor which activates at 250rpm helps the rider to start the engine with ease.The electric motor is placed on the inner side of the UCE engine to reduce the problems usually associated with the sprag clutch. The twin-pod instrument cluster is intact with odometer, speedometer, RPM meter, fuel gauge, resettable trip meter, and tell-tale lights for neutral, high beam, turn signal indicators. The blue back instrument panel is readable even in bright sunlight. The new Thunderbird twinspark is available in three colours - silver,red and black & is priced Rs. 103000.00 in (Ex-showroom) Chennai.
Main Features of New Thunderbird Twinspark:
1) New Halogen lamp replaces conventional lamp and hence increased life.
2) Foldable foot rest for the Thunderbird twinspark rider.
3) The rear brake cable is on the right side of the bike
4) Chain sprocket is moved to the right side.
A foxy combination of robust technology, higher torque,
full -bodied look & comfort styling.
The motorcycle features 40.85 Nm of torque at 3000 rpm, unique 19 -inch wheels, 280 mm front disc brake & the same engine chassis configuration being exported to Europe, USA & Australia.
Only 500 motorcycles will be made available country-wide. Hence, the charm of genuine custom accessories, viz. twin spring split sea t s, leather saddle bags and the Lexan anti-scratch wind screen will wow only a 'fortunate 500'.
Royal Enfield...a Bright Future !!!!
Royal Enfield said it would roll out four new motorcycle models by 2010-11 targeting both the domestic and international markets. Out of the four models that we plan to launch by 2010-11, two will be for International market while two will be for domestic market
Keeping in mind its market expansion, the company is also hiking production capacity of its Thiruvottiyur plant in Tamil Nadu to 60,000 units.
In the last two years alone, the company's volume has increased 25 per cent and this year it was expected to grow 15 per cent
The ELECTRAs.....a slight change from the tradition..
The release of Electra was considered to be a revolutionary change even if it shocked the traditional bullet fans a bit. The Electra is fitted with a host of user-friendly features including the revolutionary left side, 5 speed gearshift.
A Push button start and a Digital transistor coil ignition ensure quick take-offs. Gas filled shockers enable the electra to glide deftly over potholes and speed-breakers while the glass wool silencer absorbs high frequency noises.
The only electra model available in India is the ELECTRA 5S (a 350 cc model).
In UK Royal Enfield fanatics are provided with the revolutionary electronic fuel injection model (EFI) with a 500cc engine.
As for people in the United States, there is the ELECTRA X which is again a 500cc monster but without the EFI.
