Yamaha YZF-R1

Over ten years R1 passed some serious modernization, not counting the almost annual restyling. The latter refers to a radical change in 2004 and in 2006. Yamaha limited with additional «burning fat» and a small increase in horse stock (of three powerful forces - 175 hp). Engine was slightly tilted forward to 40 ° from the vertical. Because of the increasing inclination of the drive unit Deltabox frame pass from the steering column directly to the place of mounting the box on the cylinder head rather than around the block. As a result, the frame narrowed in the place of pilot’s seat. In addition, she now weighs less and is more rigid. By racing standards, the geometry of the chassis is quite conservative, but it is understandable that with minimal modification of the motorcycle turning improved.
