ROYAL ENFIELD COMMENCES COMMERCIAL PRODUCTION FROM THE ORAGADAM MANUFACTURING FACILITY

Rolling out the first motorcycle from the Oragadam plant, Mr Siddhartha Lal, MD & CEO, Eicher Motors Ltd. in the outskirts of Chennai. This is Royal Enfield’s second production facility and has been constructed at an investment of Rs 150 crore for the first phase of the facility.
The new 50-acre plant which is almost five times bigger from the original plat of Royal Enfield will significantly reduce waiting periods on Enfield bikes, however, even as we start commercial production today with the target of 175,000 motorcycles this year of 2013, “we have already begun working on the second phase of expansion at Oragadam, which will further increase the production capacity to 250,000 motorcycles in 2014." said Mr. Siddharth Lal.

Last year, the company sold 1,13,000 units, and it has grown by over 50% over the last 
couple of years. 

Siddhartha Lal, managing director and CEO, Eicher Motors Ltd. said, “We have re-tooled many of the parts that make up our motorcycles – so that they are of exacting accuracy and finish. The ability to increase capacity fast is a crucial step for Royal Enfield towards meeting our global ambitions. While we are adding new models and new dealerships in the Indian market, we are also working on building our presence globally.”

A new CED (Cathodic Electrocoat Deposition) paint shop with a capacity of 600 motorcycles per day has been set up. Further, a robotic painting system and powder coating system have 
also been employed to reduce wastage.

The new plant will help Royal Enfield to improve the quality of its motorcycles and reach out to new global markets. Built in 11 months, the Oragadam plant has been designed to optimize cost of production through relevant automation while retaining the human craftsmanship that is distinct to the iconic Royal Enfield motorcycles, the company said. 

At the same time, processes such as the pin-striping continue to be done through craftsmen 
who lend that special human touch to each motorcycle. The vehicle assembly line at Oragadam comes with several features such as ergonomic assembly work stations, torque controlled tools with feedback device and a capacity of producing one motorcycle a minute or over 800 per day on two shifts. Effective controls and process, right from material handling to review mechanisms, have been created on the backbone of a modern and strong IT infrastructure.

In addition, chassis dynamometers and a 1.4 kilometre test track within the factory premises allows for the motorcycles to be thoroughly tested before they are dispatched for customers.
The second plant would initially begin with the production of Desert Storm and Thunderbird vehicles. By the end of the year, the company expected to produce the entire range, including the Bullet and Classic, he said. Construction of the facility began in February 2012. Trial production began in January this year. Royal Enfield already has a plant in Tiruvottriyur near here. Pointing out that the U.S. was the largest export market for Royal Enfield, Mr. Lal said that last year the company shipped about 3,500 units to the country out of the total 1,13,000 units sold.

The Oragadam facility has been built with sustainability in mind from the very beginning of the design stage with several initiatives such as reduction of effluent generation at source and zero liquid discharge system of treatment. In addition conservation of resources such as electricity, water and fuel has been given top priority. Even during the construction stage, the green concept was applied such as using soil from within the site for filling, as well as using the ideal quantities of steel, concrete and cement. The focus was also on creating efficient work spaces, equipment and utilities and hence effective use of natural, diffused lighting, natural air flow inside plant and 25% of wooded area have been ensured.

ROYAL ENFIELD THUNDERBIRD TWINSPARK 350cc REVIEW / ROAD TEST & SPECIFICATIONS




Royal Enfield launched its new bike the Thunderbird Twinspark in 2008. But it was under some serious scrutiny by Bajaj Auto Ltd because of the name and the twin spark technology. Bajaj patents the twin spark technology and it had previously filed a suit against TVS motors for the same reason. But according to Royal Enfield they have not breached the patent copyrights as it holds good for 75 and 250 cc engine bikes whereas the Thunderbird is of a 350 cc version and they plan to incorporate the same technology in their future series of bikes too.


Design & Engineering :

A first look, and you would be hardly able to tell the difference between the Twinspark and any other Thunderbird, till you see the engine. It’s a contemporary looking powerplant with an incorporated crankcase and gearbox projected to lessen oil seepage. Every other bit is similar; the round headlamp, double instrument pods, front disc brake, seat and pillion backrest are all the same as the normal Thunderbird’s. A notable visual difference is the shorter muffler that we received on our test bike.
 
The panels underneath the seat feature a minuscule ‘Twinspark’ sticker, which is the lone sign of this key technical step forward of the bike. Also on either side, just beneath the tank, are round reflectors; a helpful touch when you’re emerging from a side road onto a highway.

The fuel tank is sheet-metal, and the overhang welded below it is a blemish, while the fuel tank cap looks dated. The Twinspark does well to offer slow- cam chain adjusters, as compared to the more predictable system provided on most Indian models.



Drivetrain & Performance :


The all-new engine has twin-spark plugs, an automatic decompression facility and unit-construction that the company claims has answered the crisis of oil discharge, a key problem with the old engine. Although a lot does stay alike, other important changes contain a high-flow trichoidal oil pump, hydraulic tappets, an automatic primary chain tensioner and the drive chain assembly shifted to the right side in order to reduce transmission loss.

The Twinspark benefits from TCI ignition for a fine spark. You get 2bhp more, for a figure of 19.8bhp, and 2.85kgm of torque, which is a insignificant 0.1kgm more than the older version.

Start it and you instantly notice a smoother feel near idle. The handlebars don’t judder in your hands just yet. Select first gear and as you let the clutch out, it feels a bit improved. A six-plate clutch instead of four makes the difference. As you hasten through the gears, this smoothness unfortunately diminishes however, to be replaced with Royal Enfield characteristic vibrations, Which is where it goes from bad to worse, and it’s apparent that thrashing the engine is not the way to ride this bike.



Economy :

Fuel economy is not a subject of relevance among Royal Enfield bike lovers, who will buy the Thunderbird Twinspark more for its lifestyle value, than economy.

For the record, the Twinspark returns 35.7kpl in the city and 36.8kpl on the highway.

BTW according to company the fuel efficiency ranges anywhere between 45-50 kmpl.


Ride & Handling :
  
The riding arrangement of the Twinspark is classic cruiser fare, and its saddle is a sensibly pleasant place to be on long rides.

The new bike has an integrated gearbox that produces only 10% more power and torque compared to the previous Bullets. So, there is not much to rejoice. It generates a maximum power of 20 bhp and the maximum torque is 28Nm. For an instant halt the bike requires 150/280mm brakes.

The shifting of the rear brake has become easier. The suspension is not satisfactory; it is slightly stiffer but gets better with a pillion rider. Stability on straight lanes remains good but riding into curves isn’t any great. The front tyre seems to skid while breaking that causes some kind of discomfort. The bike is recommended for city riding and for a rare long drive too.


The Thunderbird uses known, large, kicked-out forks and an extended single-downtube frame. Its gas-charged dampers at the rear are par for the course for motorcycles in India, but even on their softest setting tend to jump when pushing the bike to its edge. These work best when the bike is overloaded.


The Thunderbird Twinspark is somewhat a burden in city traffic, but a steady bike on the highway thanks to its 19-inch rims. The handlebars do provide ample weight for city riding, but there is no dodging this bike’s rangy wheelbase and heft in the city.




Popularity Rating of Royal Enfield Thunderbird Twinspark In India :

The new Thunderbird Twinspark will not have a mad following like we see for Pulsars or Karizmas but is liked by people who already own a bullet and those who do not have one but have a liking for the brand. You might not see 100s and 1000s of these on roads, but one on road and it is a head turner.



Price : 

The Royal Enfield Thunderbird Twinspark is available in three colours: Silver, Black and Red and is handsomely priced at Rs 103000.(price quoted from year 2009)

At Rs.1,00,000+ the bike is not cheap, but it is a legend cloaked in modern wizardry. Enfield claims the Thunderbird TwinSpark is maintenance free though only time will tell, as it is too early to comment on this. 



Verdict :

The dreary general quality, the heavy price tag and the out-of-date technology make sure you do not buy this bike by using your head. Yes, the new engine is better and more modern, but then these are changes that should have been made a long time ago.

But looking at the Thunderbird Twinspark as such is missing the point totally. It is a bike you buy with your heart.
