The Yamaha YZF-R1 2005 Model Specs

Overview
-	Yamaha took to a major development. This included style updates like an underseat exhaust, and performance upgrades including radial brakes and for the first time on an R1 Ram-air intake. Furthermore, the wheelie-tendency known from earlier productions is drastically reduced by changing frame geometry and weight properties. The all new engine (no longer used as a stressed member of the chassis) featured a separate top crankcase and cylinder block.
