The 2009 Yamaha R1 Bike: New Potential and Control

Yamaha R1 bikes have experienced a good status as one of the top sport bikes available over the previous ten to fifteen years. When designing the 2009 Yamaha R1 bikes, the engineers were confronted with this ambiguous dilemma: How does one improve on fineness? As Yamaha R1 motorbikes were already incorporating some of the best running bike technological know-how of the day, there was only one sensible resolution to this issue: develop new technology! In 2009, Yamaha R1 motorcycles have experienced a complete modernize to add new innovations not seen on any other motorcycle.

First, let’s quickly cover the basic specs of 2009 Yamaha R1 motorcycles before getting side tracked by specifying all the new technology it features. 2009 Yamaha R1 motorcycles feature a liquid-cooled, 998 cc, inline four-cylinder, sixteen-valve DOHC engine. They've got a six-speed manual transmission with a multi-plate slipper clutch. The Yamaha R1 engine is capable of 180 horsepower at 12,500 rpm and 85 pound-feet (11.8 kilogram-meter) of torque at 10,000 rpm. The Yamaha R1 top speed has been reported by client at or around 190 mph (257.5 kph). All this power is presently available for less than $12,500.
Now, onto the new Yamaha R1 motorcycle technology for 2009! The 2009 Yamaha R1 motorcycles are the first to feature crossplane crankshaft technology in a two-wheel motorized unit. Crossplane crankshaft technology is a extremely technical, very difficult machine, and a full explanation of it could easily fill its own article. Therefore, we’ll try to describe it in the shortest, simplest term we can.

In a traditional engine, gasoline combustion commutes pistons in up-and-down motion. The pistons, in turn, drive the crankshaft. The crankshaft turns the reciprocal motion of the pistons into rotational motion that eventually turns the back wheel of the bike. This translation from reciprocal to rotational motion is never perfect. Energy is generally lost when motion changes form, not to point out a timing delay from the pistons igniting to the wheels turning. The greater the movement and energy (in this case, the RPMs), the greater the loss in energy and movement transfer. What this means to you as a motorcycle rider is that the fast you go, the less control your throttle has over the rear wheel.
A crossplane cranksaft style takes a completely different approach. First, as a substitute of two sets of pistons firing alternately, this motor involves four sets of pistons firing in rotation. Second, the connection rods from pistons to crankshaft are positioned at ninety degrees from one another around the crankshaft. The firing order of the pistons is 270°-180°-90°-180°. The outcome of the right-angle location and non-liner firing chain is that the exchange of energy and action from the pistons to the back wheel is much more clean and accurate. What this means for you as a motorcycle driver is that your throttle has much more power of the rear wheel, allowing a steady, linear acceleration and softer handling of the motorbike, even at high speeds.

Another innovation in 2009 Yamaha R1 bikes is a forced-air consume system. This system raises air intake performance by using the organic airflow generated when riding to pressurize the air in the air cleaner box. As more air in the engine generates more potency, the new R1 engine has extraordinary power, especially at high speeds.
Yamaha has also developed the chip-controlled throttle and intake technology from racetrack motorbikes. This merges computer technology with the driver’s throttle control for electric micro-control of the fuel boost and air intake systems. The result is a throttle reaction that is both immediate and precise. Together, all these engineering improvement in 2009 Yamaha R1 bikes give more power and speed, and greater pilot control at the same time. What’s not to love?

Since one can’t entirely redesign the engine without redesigning the frame, Yamaha has done that too, including many new improvements. It includes an aluminum frame precisely well-balanced for the mixture of both stiffness and flex that a racing motor cycle needs. It also features made aluminum pistons, a light-weight titanium intake valve, and electronically actuated steering dampeners.

Despite all of 2009 Yamaha R1 motorcycles’ advantages and features, including great acceleration, exceptional responsiveness, and heightened maneuverability, it has its disadvantages like any motor vehicle. Some owners report finding it to be uncomfortable when travelling or driving long distances. The bike gives off a lot of heat, which can get not comfortable at low speeds, or in the stop-and-start nature of rush hour city traffic. On the other hand, some people may debate, 2009 Yamaha R1 motorcycles are not built for commuting - they are built for racing. If you’re looking to commute in ease, go purchase a minivan.
