YZF R15s - With Unibody Seat

A more comfortable experience


The YZF-R15s with unibody seat , designed to provide more convenience to rider and pillion both. Equipped with 150cc liquid cooled, 4 stroke SOHC, 4 Valve engine, front and rear disc brakes along with a fuel capacity of 12 litres, 5 spoke alloy wheel and sporty graphics.

YAMAHA's Humachine Technology aims to provide a superior riding experience for both rider and pillion. To create this, a Unibody seat has been adopted. This is ergonomically designed to give optimal support to rider and pillion, at all speeds, over longer duration rides as well.

Yamaha R series bikes are equipped with under cowls that are based on the image of a diffuser, to give them the best form for aero-management. These are not cowls for simply enclosing the engine, but forms composed of blade surfaces that actively control airflow. This spirit has been directly inherited by the YZF-R15s.

Liquid Cooled Engine

First Indian made model with liquid cooled Engine. Liquid Cooled Engine provide stable performance, reduce vibrations, and offer a high quality ride. The engine is surrounded by a water jacket in which coolant liquid circulates to cool the engine. While this method is widely used in automobiles and large capacity motorcycles, there are very few examples of motorcycles of this class due to increased weight from components such as radiators. YZF-R15s uses a special compact and lightweight aluminium radiator and a body design that utilizes airflow for heat dissipation. This has enabled us to create a lightweight, compact body while retaining its stable performance.

The benefits of using this method include stable performance during long-distance, high-speed riding and hill climbing. A liquid-cooled engine does not need heat-dissipating fins and therefore the engine is able to deliver its best performance without being affected by temperature. Additionally, because the head and cylinder are enclosed in a water jacket, mechanical noise from the engine is reduced dramatically. The newly developed engine delivers agile riding performance, and excellent performance on straight stretches of road as well as on winding roads. YZF-R15s also delivers excellent environmental performance. These traits are a must for an "urban supersport". The ride is unprecedented in terms of both excitement and quality.

Linked Type Monocross Suspension

YZF-R15s is equipped with a linked type monocross suspension that delivers a comfortable ride and a cushioning performance that is less prone to bottoming out. In particular, it reduces annoying "sinking" when riding tandem. The linked monocross suspension consists of a link mechanism sandwiched between the rear arm and cushion unit to create changes in the lever ratio based on the lever effect. When the shock absorber is almost fully extended, the lever ratio is high and therefore the spring is soft, and the damper works softly as well. As the shock absorber strokes in, the lever ratio gradually decreases and the spring rate increases. Eventually, when it is nearly fully stroked in, the lever ratio becomes small and the spring becomes hard and strong. The damper also becomes hard. By making changes to the lever ratio in this way, we were able to achieve soft riding comfort as well as excellent damping under intense load conditions. The optimization of the frame and rear arm rigidity of the Deltabox Frame combined with the effects of the linked type monocross suspension achieve good riding comfort, agile handling, and turnability, hardly ever causing bottoming out. As the heir to the YAMAHA R series, YZF-R15s has inherited the series' agile handling performance.

Wider Radial Rear Tyre

With a width of 130 mm, the rear tire adds to the sense of machine volume A radial tire is a tire formed around a "carcass" consisting of a radial ply with cords that run in a perpendicular to rolling direction, as if "radiating" out from the center of the tire to the two rims. The advantages of a radial tire are: (1) a high level of rigidity that reduces excessive flexing of the tread and increases grip and (2) reduced rolling resistance that contributes to better fuel economy.

The rubber compound and tread pattern, the crossing angle of the belts and the amount of turn-up in the radial carcass are designed for the optimum mutual balance to achieve excellent handling characteristics.
