Yamaha to introduce forged piston in India
March 18, 2008
Keeping up with new technology and constantly bringing it to the next level, Yamaha Motor India is set to introduce forged piston which enables lighter piston design and excellent power development, in the Indian market. The forged piston is used on the new 150cc YZF-R15, which was unveiled at Auto Expo 2008, as the first on an Indian market model and a feature that reduces the reciprocating mass of the piston by approximately 20%.
Introduced in 1997, Yamaha “controlled forging technology” has been used successfully for over a decade for the mass production of forged aluminum pistons because it utilizes a system of precise control of the piece temperature, mold temperature and the forging force. Yamaha’s controlled forging technology tightly controls the forging conditions, including (1) the initial heating of the work piece, (2) controlling the temperature of the mold so that it keeps the work piece in the ideal 400 to 500 ℃ range (3) applying just the right amount of pressure to the mold in the forging process and many more factors.
According to Mr. Sanjay Tripathi, Head of Dept- Product Planning & Strategy, “Pistons for car and motorcycle engines are usually cast by pouring molten aluminum alloy into a mold. The other type of piston is the forged piston, with which the alloy is not melted but heated to the point where it can be forged into a mold under pressure. Since the aluminum is not melted in the forging process, it retains a stronger metallurgic quality. This makes possible a thinner, and thus lighter, piston that has less reciprocating mass and also contributes to weight reduction. The result is better revving and lesser engine vibrations”.
“However, there are exacting requirements involved in manufacturing a complex shaped piston and difficulties in maintaining precise temperature in the "forging" process. Due to which such pistons are expensive to produce. But Yamaha’s "controlled forging technology" enables production of the forged pistons at a lower cost”, he adds further.
The forged pistons made with Yamaha “controlled forging technology” have excellent strength characteristics that enable the design of a thinner, lighter piston with smaller reciprocating mass achieve higher rpm and performance as well as providing the greater reliability of the higher strength aluminum. For this reason they are used in YZF-R15 and many Yamaha motorcycles.

Yamaha introduces Alba with Electric Start
May 05, 2008 India Yamaha Motor Pvt. Ltd. has announced the launch of all new Yamaha Alba106 cc with electric start and stylish and trendy graphics, thus offering robustness and solidity to its existing product range.
The unique design of Yamaha Alba 106 blends youthful style and modernism with thoughtful decency. Giving it a sturdy, macho image are the new aerodynamic cowl, well sculptured tank, well-built side and rear panel. While the exciting graphics with the smooth flowing design give the bike its stylish, super cool looks.
Since the bike has been designed for daily commuting, special emphasis has been given on shaping it for the maximum comfort of the rider. That is why, Yamaha Alba 106 boasts of broad seat for comfortable riding of the pillion rider too. The ideal ergonomics of seat, handlebar, and knee recess on the petrol tank are all designed for comfortable riding by giving the right posture to the rider.
Keeping the Indian driving conditions in consideration, Alba 106 has perfectly spaced gear ratio for driving in congested conditions without changing gears repeatedly.
At the heart of the machine is the Yamaha’s ever reliable 106cc engine, which gives good combination of low end torque and mileage leading to less strain on the engine and therefore longer life. Other features include the innovatively designed indicators and tail light and easy to read instrument consol including fuel meter.
“The launch of new Alba with electric start is in line with Yamaha’s true commitment to provide world class products to its customers. A lot of emphasis has been laid on shaping Alba for maximum comfort of the rider and its premium features will give consumers a new thrill in biking pleasure. Alba delivers comfort, style and solidity, which will make it the right choice for the discerning customers” said Mr. Takahiro Maeda Chief Sales and Marketing Officer, Executive Vice President.
The Yamaha Alba 106, billed as the family bike comes in two colours - Deep Red Metallic K and Yamaha Black at Rs. 37,500 (Ex-showroom-All India).
Alba 106 is a low maintenance bike with high fuel efficiency that enhances its value-for-money appeal manifold.
About India Yamaha Motor Pvt. Ltd.
Yamaha made its initial foray into India in 1985. Subsequently, it entered into a 50:50 joint venture with the Escorts Group in 1996. However, in August 2001, Yamaha acquired its remaining stake becoming a 100% subsidiary of Yamaha Motor Co., Ltd, Japan (YMC). In 2008, YMC entered into an agreement with Mitsui & Co., Ltd. to become a joint investor in the motorcycle manufacturing company “India Yamaha Motor Private Limited (IYM)”.
IYM operates from its state-of-the-art-manufacturing units at Surajpur in Uttar Pradesh and Faridabad in Haryana and produces motorcycles both for domestic and export markets. With a strong workforce of more than 2000 employees, IYM is highly customer-driven and has a countrywide network of over 400 dealers. Presently, its product portfolio includes Gladiator Type SS & RS (125 cc), YZF-R1 (998 cc) and MT01 (1670 cc), Crux (106 cc), Alba (106 cc), G5 (106 cc). IYM is also planning to launch 150 cc liquid-cooled YZF-R15 and 150cc air-cooled FZ in 2008.
