Yamaha has launched a new model of sport bike R1. Can he beat the legendary R6?
The first demonstration performance model R1 2007 was on track Mazda Raceway Laguna Seca near Monterey (Monterey), California.The new R1 modified chassis - some components are made more stringent, some - more flexible. YZF-R1 looks confidently at every turn - this liter bike power and weight exceeds the R6, but in managing it much easier.
R1 2005-2006 model years are often criticized on the grounds that the manufacturer has sought to minimize the engine speed. When switching speeds the driver had to hold very high engine speed, since at lower revs motorcycle behave uncertainly. This feature was included in the production of Suzuki GSX-R1000 and Kawasaki ZX-10R.
R1 2005-2006 showed excellent results on the race track, but here in the everyday life of an ordinary fan felt the relative lack of power at low and medium engine speeds. To achieve stable operation of the engine designers to abandon the traditional draft cylinder heads with five valves in favor of a more standard version with four. This innovation increased the degree of compression in the cylinders - and, hence, increased engine power. Four valves are equipped with the innovative 'YCC-I', (a two-stage fuel injection system), which opens them, depending on engine speed. When turnover below 10.400 rpm, trigger input valve length 140mm, which increases average output power at high speeds in addition to the main entrance valve is actuated and an additional - short 65mm valve.
Fuel injection control system is still the same 'YCC-T', which was presented to the model R6. On the new Yamaha YZF-R1 control fuel system is not only a sensor, located on the handle, but with the help of a mechanical cable release, coming from the arm to the fuel system. Sensor with high accuracy tells the computer how fast you need to dial or to reduce turnover, but the presence of a mechanical backup rope makes the machine secure from an unlikely computer failure.
Cylinder head and the entire engine has been redesigned. Changed exhaust system. Now the exhaust is carried out through two mufflers to compensate for the increased weight of the machine, the rest of the exhaust system is constructed from titanium to reduce weight. And if we talk about weight - this bike is the lightest among litrovikov.
Has undergone changes and braking system. Now uses hook with 6 cylinders. One need only one finger movements to slow the motorcycle.
The new bike upgraded building itself - is now free of the forks travel is reduced from 30 to 25 mm (for the shock absorbers), used wheel width 102 mm (97 mm vs. the previous model), the total length of the motorcycle increased by 16 mm. All this makes the car more responsive and obedient on the road.As before, the new model, the manufacturer updated the aerodynamics by increasing the efficiency of ventilation ducts.
Yamaha has managed to build a motorcycle, which was improved in all directions. This model will appreciate how professional racers and those who just love to ride around the city.
