2006 YZF-R1
A MASTERPIECE REFINED
More than any other motorcycle, the R1 has become synonymous with awe-inspiring engine performance and remarkable handling qualities. Yet, at the same time as being one of the world’s premier large-capacity supersport machines, the Yamaha R1 has also established a reputation for being one of the most stylish and beautifully-finished motorcycles that money can buy – in any category.On the race track the YZF-R1 has been
quick to make its presence felt, and in 2004 the R1 won three major
titles – the AMA Superstock Championship, the European Superstock
Championship, and the FIM World Endurance Championship.
R1
riders have also performed strongly in the prestigious All Japan
Championships, and the R1 was victorious in the Isle of Man TT races on
the world’s toughest road circuit. More recently the YZF-R1 had an
impressive victory in the 2005 24-hour race of Le Mans and took its
debut race win in the 2005 World Superbike Championship, underlining
the machine’s ability to win at the very highest level.
2006 R1. THE HUMAN TOUCH
The
development goals of the R1 have always been the same since day one: to
create the definitive high performance supersport motorcycle with
class-leading engine and chassis technology combined with aggressive
and distinctive styling, that delivers the ultimate riding experience
and unrivalled cornering performance.
Yamaha has always
been an innovative and forward-looking company, and for these reasons
the R1 development team are constantly striving for an even higher
degree of perfection.
When the fourth generation YZF-R1
was launched it immediately set new standards for cornering,
performance and styling, and the wide range of engine and chassis
changes introduced for 2006 are designed to enhance the R1 experience
even further. The higher powered engine and more agile chassis are sure
to underline the R1’s unrivalled cornering performance and handling
qualities on secondary roads – and will undoubtedly reinforce its
reputation as the most exciting and rewarding supersport machine.
All
these developments are the result of Yamaha’s ongoing research and
development programme, in which the R1 has been constantly pushed to
the limit by our factory test riders. It is their input that has helped
to make the latest model feel and perform the way it does, and it
underlines how human sensitivity has played a key role in forming the
distinctive character of the R1.
ENGINE 3 horsepower increase
The
2006 model runs with the same 998 cc liquid-cooled 4-stroke DOHC
4-cylinder 5-valve layout featuring a 77 x 53.6 mm bore and stroke and
12.4:1 compression ratio. Equipped with a 3-axis transmission, fuel
injection and 40 degree forward slanted cylinders, this ultra-compact
powerplant is one of the most highly respected supersport engines of
all time.
Yamaha’s engineers have conducted a
thorough examination of the R1’s intake and exhaust efficiency, and for
2006 a range of detailed changes in this area have achieved a 3 Hp
increase in power at 12,500 rpm without direct air induction.
One
of the most significant changes is the use of shorter intake valve
guides for 2006. Measuring 27.5 mm, these new guides are 5 mm shorter
than the 2005 model, and this 15% reduction in length increases engine
efficiency by increasing intake air flow, and reducing frictional power
losses. To match the new intake valve guides, the 2006 model also
features smoother intake ports. Furthermore, the clutch boss has been
modified to increase the oil flow to the clutch assembly.
Other detail changes
The
design of the compact cam chain tensioner has been revised, and now
features a different sealing system for improved durability. The
overall length of the main gear axle is increased by 5 mm, and the
engine cover is modified accordingly.
