- Humachine Technologies & Sensual Racing Form -
The YZF-R1 and YZF-R6 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-R15 version 2.0.
“Harmony between rider and machine.” YAMAHA's Human Technology involves studying the form of the motorcycle actually in motion with the rider on it. The R series is the embodiment of 1) a wide frontal space that protects the rider, 2) an easy to ride seating area that gives riders the freedom of movement and allows them to steer effectively, 3) the glamorous tail treatment that takes into account the management of airflow behind the rider, and 4) a sensual racing form that brings all 3 of these elements together in a harmonious package. These characteristics have been splendidly reproduced in the YZF-R15 version 2.0.
The YZF-R15 version 2.0 is a new model that has been developed under the concept of a “Graded Up R15.” While maintaining the proven ease of handling of the existing R15, the R15 version 2.0 boasts of spruced up looks and better performance in circuit riding. The design elements are borrowed from the supersport model YZF-R1 that is adapted from YZR-M1 MotoGP race machine.
The YZF-R15 version 2.0 – is a 150cc liquid-cooled 4-stroke fuel injected bike. The R15 version 2.0 has undergone changes as compared to the present YZF-R15 in the specs of the Engine Control unit (ECU), drivetrain unit, a long aluminum swing arm, wider front and rear tires (radial tire for the rear), split seat, LED taillights and new-design middle cowl & tail cowl.
The R15 version 2.0 has undergone changes in the specs of the Engine Control unit (ECU), drivetrain unit, a long aluminum swing arm, wider front and rear tires (radial tire for the rear), split seat, LED taillights and new-design middle cowl & tail cowl to experience the leaner and meaner performance.

Features:
Liquid-cooled Engine
First Indian made model with 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-R15 version 2.0 uses a special compact and lightweight aluminum 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-R15 version 2.0 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.

After Mr. Thanawi sent me the SMS about the availability of the 2012 Y125ZR, BLH Motor has uploaded new images of the 2012 Y125ZR in their FB fan page and shows that they have ready stock of the bike. I also have called GTMax and they also confirmed that the bike is already at their shop. So, I think this means that the bike is also available at the shop near you (not sure if you are in Sabah, Sarawak and Labuan).
