A Review of Yamaha YZF R1
The Yamaha YZF-RI was launched specifically to offset the shortcomings of the previous Genesis engine, which had problems with the crankshaft and output shafts. The Yamaha YZF-R1 engine was designed to be shorter and has the wheelbase shortened to allow for a quicker handling. Other serious problem that the manufacturer wanted to correct was the clutch problem, which made the earlier model of the bike to be recalled to the factory.
The birth of the Yamaha YZF-R1 is connected to the YZF1000R because during official launching ceremony of YZF1000R in Cape Town, South Africa the idea was born. At this venue, a group of the Japanese engineers discussed this new idea with the European based Yamaha planners. The idea of manufacturing a rather radical motorbike was flouted and a need for producing a rejuvenated race-bred bike emerged. It was agreed that the demand for super sport machines in Europe was high and therefore it was imperative to manufacture a Yamaha bike that can meet this demand. At the meeting the following specifications were discussed
- The YZF-R1 is a super sport bike and thus to be designed with this idea in mind.
- The bike to have a short 4 cylinder engine. With a gearbox and a crankshaft.
- A delta box II chassis
- Ultra long swingarm
- Best weight distribution at the center of the bike.
The 2009 model had a throttle control valve, which gives the rider the option to choose the distinct map. The bike has an A- mode that allows the rider more power from the mid level to the lower RPM range.
The 2012 Yamaha YZF-R1 model is not very different from the earlier versions. The difference is that this model is a mere upgrade with traction control system being the only update the bike boasts of. The 2012 model has also an improved nose, a muffler end caps, a gripper foot pegs, and a longer sear shock.
- It has a 998cc 4 stroke DOHC liquid cooled 16 valves engine
- The ignition is transistor controlled
- Compression ratio is 12.7.1
- Fuel delivery is via fuel injection with YCC-T and YCC-l
- Maximum speed 299km/hr
- The bore and stroke length is 78.0mm x 52.2 mm
The performance of the Yamaha YZF-R1 is great, unlike other bikes; the rider of this bike does not shake violently as it is with other bikes when accelerating or decelerating. The bike has also been able to perform well in a number of championships it has participated in and hence it is one of the motorcycles to buy if racing is your hobby.
