YAMAHAYZF-R6S 2008 - 2009

　　In 2009, Yamaha launched the YZF-R6S, a more civilized and street-friendly version of the R6 superbike, lightweight and powerful with razor-sharp handling and a comfortable cockpit that made it a do-it-all sports bike.

　　The lightweight aluminum Deltabox frame offered the perfect rigidity balance with its engine used as a stressed member and the removable aluminum rear subframe with fewer welding points that reduced weight, which resulted in a light frame design and great handling response.

　　In the performance department, the model featured an ultra-compact, lightweight engine with lightweight forged pistons for better engine response and a powerful 32-bit Electronic Control Unit (ECU) with computer-perfected mapping that provided precise ignition timing, maximum response, and more power output.

　　As for the power figures, the 2009 Yamaha YZF-R6S had its heartbeat set by a 599cc four-stroke four-cylinder liquid-cooled engine that delivered an output power of 129 hp with a peak at 14,500 rpm and 66 Nm (49 lb-ft) of torque available at 11,000 rpm.

　　For suspension, the model packed a 41 mm adjustable upside-down fork on the front and a fully adjustable shock absorber on the rear.

　　In addition, the model packed a durable, lightweight aluminum clip-on handlebar that reduced vibrations, an adjustable front brake lever, a special lightweight O-ring chain, a lightweight aluminum side stand, and chain adjusters, and a lightweight and low-maintenance sealed gel-type battery.
