The Yamaha YZF-R6 is probably one of the most desired secondhand motorcycles in Thailand. The 2008 Yamaha R6 with its four-cylinder inline engine has not only the looks, it has the engine to backup the claim that it is a sportsbike.
The bodywork of the 2008 Yamaha YZF-R6 is modern, and the size of the front and rear cowls are reduced in size and the mirrors are easier to get off for a potential trackday.
On the 2008 Yamaha R6 the handlebars are 5mm further forward and 5mm lower down than earlier models, making the weight bias of the motorcycle 52 to 48% to the front. Which makes a more comfortable riding position.
The frame stiffness started with 2008 has been altered, with the use of thinner metal for the frame and thicker headstock area. The cross-member between the twin spars has been removed. A stiffer headstock and a more flexible frame is the result. The subframe is made from ultra-light magnesium alloy and it really is light, 450 grams less than on the older models. The front forks on the 2008 Yamaha YZF-R6 come with longer tubes and a longer top-out spring to help increase stability. There's a stiffer top clamp too.
The 2008 Yamaha YZF-R6 was one of the last non-restricted inline-four sportsbikes, it had a claimed power output of 133 horsepower at 14,500rpm. The 2013 Yamaha YZF-R6 maximum power output is limited to 123.7 horsepower due to all sorts of environmental restriction to keep the motorcycle street legal.
While the original exhaust pipe of the 2008 R6 was less restricted than the current model, you could gain some performance boost by replacing it with an aftermarket exhaust system. The original exhaust cylinder pipe where not all the same diameter on this model, the connecting pipe between the second and third cylinder pipes was 30 percent thicker than the other two to produce some more torque at high revs.
