The 600cc DOHC 16-valve, liquid-cooled titanium-valved four-cylinder engine is both compact and high-revving mainly thanks to the 67.0 x 42.5mm bore and stroke, which translates into a 13.1:1 compression ratio and implicit satisfying throttle response. But is that enough to turn this engine into the blast provider that riders brag so much about? Certainly! Thisd one has a FMF pipe on it, it has a great sounding, mellow tone to it. It also has frame sliders, and swing arm spools that have been added to it. The chassis remains a proven track performer composed from an aluminum Deltabox frame, four-way adjustable suspension and five-spoke 17-inch wheels. As a road & track motorcycle, the 2007 Yamaha R6 is hard to fault. Steering’s light and neutral, direction changes are fast and effortless and it’s more stable than such a light, nimble motorcycle has any right to be. Lines and corner speed that’d be impossible on other bikes are child’s play on the 2006 Yamaha R6.
