2009 Yamaha R1 Bike: Excellent Power And Control
First, let’s quickly cover the basic specs of 2009 Yamaha R1 bikes before getting sidetracked by describing all the new technologies it benefits. 2009 Yamaha R1 motorcycles feature a liquid-cooled, 998 cc, inline four-cylinder, sixteen-valve DOHC engine. They've a six-speed manual transmission with a multi-plate slipper clutch. The Yamaha R1 engine is able 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 consumer 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 highly 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 moves pistons in up-and-down motion. The pistons, in turn, drive the crankshaft. The crankshaft turns the reciprocal motion of the pistons into rotational action that eventually turns the back wheel of the motorcycle. This translation from reciprocal to rotational motion is never perfect. Energy is generally lost when motion alters form, not to bring up a timing delay from the pistons igniting to the wheels turning. The greater the motion and energy (in this case, the RPMs), the greater the loss in energy and motion transfer. What this suggests you as a motorcycle rider is that the fast you go, the less control your throttle has over the rear wheel. A crossplane cranksaft design takes a completely different approach. First, instead of two sets of pistons firing alternately, this motor involves four sets of pistons igniting in rotation. Second, the connection rods from pistons to crankshaft are put at ninety degrees from each other around the crankshaft. The firing order of the pistons is 270°-180°-90°-180°. The outcome of the right-angle area and non-liner firing chain is that the exchange of energy and action from the pistons to the rear wheel is much more smooth and exact. What this means for you as a motorbike rider is that your accelerator pedal has much more control 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 motorcycles is a forced-air intake system. This system raises air intake performance by using the organic airflow generated when riding to pressurize the air in the air cleaner container. As more air in the engine generates more strength, the new R1 engine has exceptional power, especially at high speeds. Yamaha has also adjusted the chip-controlled throttle and intake technology from racetrack motorcycles. This combines computer technology with the driver’s throttle control for electronic micro-control of the fuel injection and air intake systems. The result is a throttle response that is both instantaneous and exact. Together, all these hi-tech progress in 2009 Yamaha R1 motorbikes deliver more power and speed, and better pilot control at the same time. What’s not to adore? Since one can’t totally redesign the engine without redesigning the frame, Yamaha has done that as well, consisting of many new improvements. It features an aluminum body precisely well balanced for the mixture of both firmness and flex that a racing motor cycle demands. It also includes crafted aluminum pistons, a light-weight titanium consumption valve, and electronically actuated steering dampeners. Despite all of 2009 Yamaha R1 motorcycles’ advantages and features, including great acceleration, excellent responsiveness, and heightened adaptability, it has its weaknesses 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 uncomfortable at low speeds, or in the stop-and-start nature of rush hour Metropolis traffic. On the other hand, some people may argue, 2009 Yamaha R1 motorcycles are not built for commuting - they're built for racing. If you’re looking to commute in relieve, go buy a minivan.
