How to increase thump in Royal Enfield?

About 80% of Royal Enfield UCE owners have same question in their mind that "How can i increase the thump in my new Royal Enfield UCE?"

 Due to exhaust emissions, pollution norms and taking care of international standards for export models Royal Enfield Developed an engine inspired from International Market – “The Unit Construction Engine” which is a Euro IV compliant engine.

However, as exhaust emissions get tighter by the day, so do the noise limitations. In order to achieve both and do so comfortably, the modern Enfield has an engine of unit construction (engine & gearbox in one unit).

Right from the design itself, it is supposed to provide more refinement (meaning less noise and vibration).

So, to only way to increase the thump in Unit Construction Engine Is the “Short Bottle” free flow silencer which traditionally came with the Standard Bullet since we’re seeing bullet on indian roads.

Short Bottle is a perfect fit for new engines as well as the older ones as it has some kinda relation with “The Bullet”. You can install any silencer on your bull but none can satisfy you as the Short Bottle.

One can also go for Goldstar/Indore Silencer as they are know for there quality built and quality sound.

Before installing the Short Bottle/Goldstar/Indore Silencer make sure that your bullet has completed few thousand kilometres. After installing a short bottle you’ll obviously need to rejet your BS29/UCAL carburetor if UCE or Mikuni VM-24, VM-28 if CI engine for consistent performance.

Visit the Service Center or Consult a mechanic for rejetting of carburetor.

Enjoy the thump…

Royal Enfield Launches Thunderbird 500

Royal Enfield on Thursday launched its Thunderbird 500, which, it says, would enhance the pleasure of leisure motorcycling.

The motorcycle is now powered with 499cc Unit Construction Engine and 27.2 bhp, 41.3Nm single cylinder engine is a straight lift from the Classic 500 and gives better performance and cruising ability at the same time returning decent fuel efficiency as well. 

The Thunderbird 500 is now having innovative features like projector head lamp, LED tail lamp, daytime running lights , digital trip meter,  split seat and a blackened engine, the main ignition lock also functions as a central steering lock. The Thunderbird 500 also sports a major upgrade in terms of its mechanicals  that ensure safety of both the rider and the bike.

The bike also gets fatter front forks and all-new swingarm and a 240mm disc brake at the rear along with a 280mm disc in the front. Ground clearance has been increased to 140mm while the overall height of the bike has dropped by 5mm. Now it has 18-inch rear wheel size along with a 19-inch front tyre. The Thunderbird 500 also features a bigger 20-litre fuel tank and will be available in two shades of black.

They haven't just plonked in a larger engine and called it a day though, the whole bike gets a significant overhaul along with a new heart. 

The new Thunderbird, targeted at the highway cruising buffs, are priced at Rs 1,82,571 (on road Mumbai for the 500 cc) and Rs 1,43,346 (350 cc).

Senior Vice-President for Sales and Marketing, Shaji Koshy said “the company has already got 100 bookings within hours of launch, 50 from Mumbai alone.”

“With the launch of the Thunderbird 500 with its unique 360-degree design language and its higher powered engine, we have again upped the ante in leisure motorcycling. We have been selling around 1,000 units per month of the Thunderbird 350 and we expect this number to rise significantly with these two products,” said Siddhartha Lal, MD & CEO, Eicher Motors, while speaking toThe Hindu.

Royal Enfield claims a total range of 500km now, with the larger tank, so tourers, get ready to get your paws on it.

The Chennai plant would make engines for products assembled at the new plant coming up at Oragadam, near Chennai, said Mr. Lal. It would come up by March 2013.

Last year, Enfield had notched up a full 50 per cent growth in sales to over 75,000 units, Lal said. “The new plant would initially only make Thunderbird bikes and we would have a combined capacity of 150,000 units per annum. However, by 2014-15, this capacity will increase significantly,” he said. The company is investing Rs. 150 crore in the new plant.

Royal enfield is now promising a better service experience with all new technology to be used in servicing the newer models with trained mechanics.

What is the method or How to improve Royal Enfield Thump?

Q: I have royal enfield electra twinspark uce

2010 model

I removed & changed the bend-pipe.

I have installed the free flow silencer but there is no original thump.

Ans: About 80 % of Enfield buyers do so because they are in love with the sound. However as exhaust emissions get tighter by the day, so do the noise limitations. In order to achieve both and do so comfortably, the modern Enfield has an engine of unit construction (engine & gearbox in one unit).

Right from the design itself, it is supposed to provide more refinement (meaning less noise and vibration). So if the engine itself produces less noise, how can you get the old thump just by changing the silencer ?

ROYAL ENFIELD THUNDERBIRD 500cc REVIEW / ROAD TEST / SPECIFICATIONS / PRICE

The Thunderbird 500 has been perhaps one of the most anticipated offering from the Royal Enfield stable considering that the Thunderbird 350 has been doing yeoman service for the last ten years. The Thunderbird has built for itself a reputation of being a comfortable touring motorcycle and is often the first choice amongst the Royal Enfield models for touring enthusiasts. The Thunderbird has earned itself the reputation of a capable highway tourer and established itself firmly in the cruiser market. The Thunderbird broke away from the mould of Royal Enfield’s traditional motorcycles and redefined a new lineup. In that direction, the new Thunderbird has come as fresh motorcycle. 

Styling :

The ‘black’ engine is one of the first styling elements that catch your attention the moment you see the motorcycle. The seat has been completely redesigned to suit the new foot pegs position. The handle bar too has received changes for better reach and ergonomics.The high rise handlebars, forward placed foot-pegs and a low seat height enable a rider to cover distances comfortably for longer periods of time. Other small styling elements that a keen enthusiast will notice are the Royal Enfield logo on the all new foot-pegs, new design mirrors.

Seats :

The seat now opens using a lock mechanism, accessible through the side panel. True to its design concept as a more touring friendly motorcycle, the separately mounted pillion seat can be removed to accommodate luggage. The pillion grab rail is an all new pressure die cast component and lends to the modern design of the motorcycle. Bungee hooks provide the much needed bungee points to tie luggage.

Instrument Cluster :

The new front end lends itself nicely to the muscular stance of the bike. The instrumentation also includes two digital trip meters, allowing riders to keep a track of total trip mileage as well as intermediate mileage between tankfuls. The speed and engine rpm are shown via tastefully designed analogue clocks, housed in all new twin pods at the front. The main ignition lock also functions as a central steering lock. The inclusion of hazard lamps in the switch gear is a first for a motorcycle manufactured in India. The tank cap is placed asymmetrically on the top right hand side of the tank, instead of the conventional central mounting; a distinctive styling element of the Thunderbird 500.

Engine :

It now comes loaded with a 500cc Unit Construction Engine (UCE) and additional power makes covering distance an easier task. The seamless torque delivery will keep the rider entertained through the twisty sections. A flick of the right wrist is all it takes now to overtake a slower moving vehicle or climb up a twisty section. When it was time to build a Thunderbird 500, Royal Enfield decided that it had to offer more than what customers were used to seeing from the Thunderbird in its current guise. Apart from the larger engine, the bike now features 41mm thick forks in front and an oval section swingarm at the rear to allow the rider to handle the additional power. The inclusion of a rear disc brake will now allow the rider to confidently explore the upper limits of the motorcycle’s performance capabilities. 

Fuel tank :

Since Royal Enfield's are mainly associated with tour and leisure purpose and to tackle this issue Thunderbird 500 comes equipped with a massive 20-litre fuel tank for an enhanced range.

Ergonomics :

The designs are now oriented to the cruiser character of the motorcycle. The seat has been completely redesigned to suit the new foot pegs position. The handle bar too has received changes for better reach and ergonomics. The seat now opens using a lock mechanism, accessible through the side panel. True to its design concept as a more touring friendly motorcycle, the separately mounted pillion seat can be removed to accommodate luggage. The pillion grab rail is an all new pressure die cast component and lends to the modern design of the motorcycle. Bungee hooks provide the much needed bungee points to tie luggage.

Headlight and Tail light :

Night time visibility has been the biggest challenge faced by most motorcyclists while cruising on the highway hence the new headlight with a 55w projector lamp for its low beam and a 55W halogen bulb for the high beam addresses that issue. The lighting is at its brightest with the high beam on, working in combination with the projector lamp giving ample spread and penetration on the road. Tail lamp comes with LED lamp with position light guides which is new for Royal enfield family.

Brakes:

The bike comes loaded with front 280mm Disc, 2-Piston caliper brakes. Stopping power has been aided with the addition of a disc brake at the rear. The braking system is supplied by Bybre, a fully owned subsidiary of Brembo. It is mounted on the new improved oval section swing arm. These changes will enhance the riding experience of the motorcycle on the highway. 

Price :

The price of the Thunderbird 500cc is expected to be ten thousand higher than the Classic Chrome which makes the bike the flagship motorcycle of Royal Enfield’s portfolio.
