Yamaha Version 2.0

Racing Instinct. Passing on the “R series” DNA —

Technologies Sensual Racing —

The YZF-R1 and YZF-R6 are with under cowls are based on the image of a diffuser, to them the best form for These are not cowls for simply the engine, but forms composed of surfaces that actively airflow. This spirit has directly inherited by the YZF-R15 2.0.

“Harmony between and machine.” YAMAHA’s Human involves studying the form of the actually in motion with the on it. The R series is the embodiment of 1) a wide space that protects the 2) an easy to ride seating that gives riders the of movement and allows them to effectively, 3) the glamorous tail that takes into the management of airflow behind the and 4) a sensual racing form brings all 3 of these elements in a harmonious package. These have been splendidly in the YZF-R15 version 2.0.

The YZF-R15 version 2.0 is a new model has been developed under the of a “Graded Up R15.” While the proven ease of handling of the R15, the R15 version 2.0 boasts of up looks and better performance in riding. The design elements are from the supersport model that is adapted from MotoGP race machine.

The version 2.0 – is a 150cc liquid-cooled fuel injected bike. The R15 2.0 has undergone changes as compared to the YZF-R15 in the specs of the Engine unit (ECU), drivetrain a long aluminum swing wider front and rear (radial tire for the rear), seat, LED taillights and new-design cowl tail cowl.

Fuel Injection

Fuel is used to ensure excellent efficiency as well as environmental

The two components of the fuel injection used in YZF-R15 version a) the sensors that gather on the engine’s operation, and b) the fuel system that supplies have both been to be lightweight and simple. The sensor uses only 4 sensors blinking points) to gather amounts of information relating to operations, which is sent to a 26-pin ECU, which in calculates the optimum fuel

The fuel supply component of a small, fuel pump, regulator and filter, and a small all of which come together to a lightweight, compact form. The injects finely atomized of fuel through 6 hole injectors.

In order to maximize the of the fuel injector, which the optimum amount of fuel for amounts of intake air, version 2.0 is equipped with a 3-liter air cleaner. The duct of the intake duct was designed to optimize the flow of intake

Additionally, the use of a 4-valve combustion (a combustion chamber with 2 and exhaust valves each) has designers to layout the spark at the center of the combustion chamber for flame propagation. This increases the total valve relative to the 2-valve chambers for intake/exhaust efficiency (volumetric YZF-R15 version 2.0 is fitted a hemispherical 4-valve combustion a configuration that allows and exhaust valves to be laid out in the size possible.

In addition, the intake and exhaust angles have been small to achieve optimum chamber configuration. We also at minimizing the surface area/volume (S/V ratio) in the combustion which is key to improving fuel In conjunction with the fuel system, this combustion contributes to comfortable riding long-distance rides as well as medium to high-speed riding.

version 2.0’s engine excellent response, fuel is environmentally friendly and a comfortable

Liquid-cooled

First Indian model with cooled Liquid Cooled Engine stable performance, reduce and offer a high quality

The engine is surrounded by a water in which coolant liquid to cool the engine. While method is widely used in and large capacity motorcycles, are very few examples of motorcycles of class due to increased weight components such as radiators. version 2.0 uses a special and lightweight aluminum radiator and a design that utilizes for heat dissipation.

This has us to create a lightweight, compact while retaining its stable

The benefits of using this include stable performance long-distance, high-speed riding and climbing. A liquid-cooled engine not need heat-dissipating fins and the engine is able to deliver its performance without being by temperature. Additionally, because the and cylinder are enclosed in a water mechanical noise from the is reduced dramatically.

The newly engine delivers agile performance, and excellent performance on stretches of road as well as on roads. YZF-R15 version 2.0 delivers excellent environmental These traits are a must for an supersport.” The ride is unprecedented in of both excitement and quality.

Cylinder

The DiASil Cylinder was from YAMAHA’s world-class … casting technology.

Cylinders are all-aluminum cylinders by YAMAHA’s proprietary aluminum casting technology. An aluminum with 20% silicon content is to create a very hard, cylinder surface, making iron sleeves obsolete. As a the entire cylinder can be made of a better conductor of heat, means the cylinder delivers heat dissipation and less (Aluminum’s heat conductivity is 3.1 that of iron.) YZF-R15 is with this all-aluminum called the DiASil Cylinder and a piston, the same type of used in YAMAHA’s supersport

The fact that both the and cylinder of YZF-R15 version 2.0 are ensures excellent heat eliminates heat-induced engine loss, and helps improve efficiency. The DiASil Cylinder is a special surface treatment to oil evaporation from the cylinder’s and improve oil consumption. The cylinder has excellent hardness and is considerably to wear compared to conventional sleeves.

Additionally, the piston is in a forging process, the optimum way of lightweight designs.The reciprocating with the forged piston is 20% less ( according to Yamaha ) than with an engine of the displacement fitted with a cast aluminum piston. in an invigorating feeling when up. Conventional pistons are typically in a casting process where aluminum is cast in a mold.

developed its proprietary “controlled technology” in 1997, which mass production of forged pistons. These pistons been used in sport such as the R series. The same process was used to develop version 2.0.

Forged retain the excellent strength of alloys because the metallurgic of aluminum is not affected during the process. Therefore, the piston can be lighter and thinner.

YZF-R15 2.0 is packed with state-of-the-art that is used in the world’s bikes.

Chassis


Deltabox

The frame, which forms the for riding comfort and handling is a Deltabox frame which superior rigidity balance.

frame was designed to provide the balance in longitudinal, lateral, and rigidity. The synergy created by each dimension delivers a riding feel as well as and agile riding performance.

The frame was commercialized based on the and know-how accumulated through involvement in Moto GP since the 1980s. This type of is currently used in YAMAHA’s R of sport models. The engine is on rigid supports; one on the head and two on the case side; so that the itself becomes a structural contributing to body strength and

The engine’s low vibration makes supports possible, ensuring low and excellent balance of rigidity. rigidity refers to the frame’s to deformation when a twisting is applied to the pivot with the head pipe held in

Linked type Monocross

YZF-R15 version 2.0 is equipped a linked type monocross that delivers a comfortable and a cushioning performance that is prone to bottoming out. In it reduces annoying “sinking” riding tandem.

The linked suspension consists of a link sandwiched between the rear arm and unit to create changes in the ratio based on the lever When the shock absorber is fully extended, the lever is high and therefore the spring is and the damper works softly as As the shock absorber strokes in, the ratio gradually decreases and the rate increases.

Eventually, it is nearly fully stroked in, the ratio becomes small and the becomes hard and strong. The also becomes hard. By changes to the lever ratio in way, we were able to soft riding comfort as as excellent damping under load conditions.

The optimization of the and rear arm rigidity of the Deltabox combined with the effects of the type monocross suspension good riding comfort, handling, and turnability, hardly causing bottoming out.

As the to the YAMAHA R series, YZF-R15 2.0 has inherited the series’ agile performance.
