Yamaha YZF-R15

Yamaha has launched 150cc YZF R15, which has a profusion of magnetic power with its advanced racing technology designed to give the best performance. The new Yamaha YZF-R15 is designed in such a way so as to give best performance and better mileage, apart from the look of the sport bike. There have been complaints about the tyres being small. But the bike has good grip on the road, especially during rains. So far so good save the small tyres, a matter which is more concerned with the bike buffs.

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.
