2015 Yamaha YZF-R1

2015 Yamaha YZF-R1
MSRP $16,490

The Yamaha YFZ-R1 is back in 2015 with everything inside the engine case new from the issues from previous years’ models. The bore/stroke formula was modified (more oversquare) for increased top-end performance as the cylinders are offset toward the center of the crankshaft to reduce friction. Rocker-arms augment the shim-under-bucket valvetrain allowing for more aggressive camshaft profiles and the titanium connection rods were also installed. All told Yamaha YFZ-R1 claims the engine is 1.2 inches narrower at the crankshaft and nine pounds lighter than the 2014 model. Lastly, the six-speed transmission was revamped and is matched to a cable-actuated racing-style slipper clutch and electronic quickshifter.
