With the competition advancing, Yamaha made some major changes to the model. This included style updates, like an under seat twin exhaust, and performance upgrades including radial brakes, and, for the first time an R1 Ram-air intake. Furthermore, the tendency for wheelies by earlier productions was reduced by changing the geometry of the frame and weight distribution. The all-new engine was no longer used as a stressed member of the chassis, and featured a separate top crankcase and cylinder block. 04 05
