== Overview ==
Yamaha XJ6 Diversion





















Newly-developed 600cc liquid-cooled 4-stroke inline 4-cylinder engine

The XJ6 Diversion is driven by a newly developed 600cc liquid-cooled 4-stroke
inline 4-cylinder engine which has been specifically designed to produce brisk
performance together with an easy, predictable and linear power band.
This new design employs the basic architecture of the highly successful FZ6
engine
- and shares its bore x stroke dimensions. However, although the engine's
external appearance is similar to the FZ6, the XJ6 Diversion powerplant is
equipped with a wide range of new model-specific features.
Virtually every major feature on the XJ6 Diversion engine is new, and the
cylinder head, crankcase, intake/exhaust systems, clutch and shifter have been
developed specifically for this new middleweight. By optimizing the new engine's
entire gas flow
- from the air/fuel mixture right through to the combustion and exhaust
processes -Yamaha's team of engineers have successfully created a highly
responsive and characterful new engine with a linear and rider-friendly torque
character.

Easy-to-handle torque output

Featuring bore x stroke dimensions of 65.5 mm x 44.5 mm, together with a high
compression ratio of 12.2:1, this strong and responsive new inline-4 cylinder
engine produces maximum horsepower 57.0 kW (78 PS) at 10,000 rpm, with maximum
torque 59.7 Nm (6.1 kgf-m) at 8,500 rpm.
During the engine development process, a major goal was to create a
rider-friendly torque output, and many of the design features seen on the new
engine were introduced in order to achieve brisk yet smooth power
characteristics that would be appreciated by new and experienced riders alike.




The new engine internals - as well as the intake and exhaust systems - have
been tuned to deliver plenty of easy-to-handle torque in the low to mid rpm
range. These new design features have been successful in achieving the aims of
the engineers, and the new XJ6 Diversion delivers a relatively linear power and
torque feel which offers a very special ride quality, together with strong
performance in the most frequently-used rpm range.

Newly-designed cylinder head

In order to enhance low to mid-range torque, and also ensure good throttle
response combined with an easy-to-use character, the XJ6 Diversion is equipped
with a newly-designed cylinder head. The inlet and exhaust valve diameters on
the 4-valve head design are the same as those on the FZ6 for optimal gas flow
efficiency, and for an increased torque feel in the low to mid engine speed
range, the new XJ6 Diversion features reshaped inlet ports.
In addition to the reshaped inlet ports, the new head is fitted with 32 mm
throttle bodies, and these, combined with the slimmer ports, help to ensure
optimized intake air volume.

New camshaft profiles

Another significant model-specific feature that has been developed for the
new XJ6 Diversion is the use of redesigned camshafts which have been developed
to complement the advantages gained by the revised inlet port shape.
The new camshaft designs give a revised valve lift of 6.6 mm together with a
narrow overlap of 34 degrees where the four intake and exhaust valves are all
open. Together with the new engine's high compression ratio, this specification
makes for high torque in the low to mid-rpm ranges, and also ensures excellent
throttle controllability in the frequently used 4,000-5,000 rpm band.
Another advantage of the narrow overlap is that it minimizes the blow-by of
unburnt gases, which helps to ensure increased combustion efficiency, and it
also contributes to high levels of fuel efficiency and enhances the
easy-to-handle nature of the new 600cc engine.

One-piece cylinder and upper crankcase

The XJ6 Diversion engine benefits from the use of a newly designed one-piece
cylinder and upper crankcase assembly, and this efficient design gives an
optimum balance of rigidity. In order to ensure consistently high levels of heat
dissipation, the 65.5 mm diameter bores are treated with a ceramic-composite
plating process, using Yamaha's unique high-speed plating technology.


Forged aluminium pistons

The new XJ6 Diversion engine is equipped with forged pistons which offer a
number of advantages over cast pistons. During the forging process the aluminium
alloy is heated and the piston is formed under pressure without actually melting
the aluminium. Unlike casting, in which the molten aluminium is poured into a
mould, the forging process allows the aluminium to retain more of the original
strength of the metallurgic matrix.
Consequently, the forged pistons used on the XJ6 Diversion can be made
lighter than the equivalent cast piston, and this weight reduction helps to
minimize vibration, and also reduces reciprocating weight to give instantaneous
throttle response.


Optimized fuel injection mapping

For excellent response together with good environmental performance, the XJ6
Diversion is equipped with four-hole two-direction injectors with a high dynamic
range, while a 32-bit ECU delivers precise injection control. The actual fuel
injection hardware is similar in appearance to the system used on the FZ6, but
important changes have been introduced. Modifications have been made to the
sensor and also to the software in order to enhance the XJ6 Diversion's highly
responsive, rider-friendly character, and to ensure strong overall performance.
The revised fuel injection mapping has been designed to match the new engine
specifications and optimize the linear power characteristics and enhance torque
levels in the low to mid range.


4-1 exhaust with midship muffler

The newly designed 4-1 type exhaust system features four exhaust pipes which
flow neatly into a single midship muffler which sits beneath the centre of the
new tubular steel chassis. The three-stage expansion muffler emits an attractive
exhaust note, and is equipped with a three-way catalytic converter for good
environmental performance. The system is also fitted with an O2
sensor which monitors exhaust gases, and transmits this data to the ECU, which
instantaneously adjusts the fuel/air mix to the optimum level to ensure
effective catalyzer operation.

New clutch and shifter design

The XJ6 Diversion is designed to be a modern, practical and fun middleweight
which is attractive to new and experienced riders, and in order to make it even
more easy to use on city streets, a completely new clutch and shifter are
fitted.
The new clutch has an inner-push type release mechanism, and this system is
renowned for its ease of use. With its smooth and light operation, the new
inner-push clutch offers good feel when it is semi-engaged, giving the XJ6
Diversion rider a good feeling of control in typical urban stop-start riding
situations.
As well as an all-new clutch design, this lively new middleweight benefits
from the fitment of a completely new shift system. Combined with the new clutch,
the redesigned shift mechanism delivers smooth and easy shifting in all
situations, making this attractive new motorcycle an ideal choice for those
riders looking for a thoroughbred, value-for-money middleweight.

Chassis
Newly-designed tubular steel diamond-type frame

In order to be able to offer XJ6 Diversion riders strong all-round running
performance, together with a low seat height and slim overall chassis
dimensions, we have developed an all-new diamond-type frame. Manufactured from
high tensile steel pipes which are 31.8 mm in diameter and 2.3 mm thick, this
attractive new frame features a very simple and neat design which has been
created using the minimum number of bends and welds.
The inline-4 cylinder engine is supported at four points on the frame by
means of rigid mounts, and by using the 600cc powerplant as a stressed member of
the chassis, our designers have been able to create an attractive and simple
frame layout.
This new frame delivers easy handling combined with impressive ride quality.
For smooth cornering performance and increased surface feedback, the lateral
rigidity balance of the new frame has been optimized, giving a responsive
handling package that instils confidence.

Dimensions and geometry chosen to deliver optimum balance

Featuring a 1,440 mm wheelbase together with a caster angle of 26 degrees and
trail of 103.5 mm, the chassis geometry is designed to give balanced and
predictable handling characteristics which respond in proportion to the rider's
inputs.
This 1:1 handling relationship is one of the most significant facets of the
new XJ6 Diversion's character, and its rider-friendly chassis performance looks
set to ensure that this new bike quickly establishes itself as one of the most
complete and most attractive models in the 600cc class.



New 41mm diameter front forks

To complement the new slimline tubular chassis, the XJ6 Diversion is equipped
with newly-designed conventional front forks featuring 41 mm diameter tubes
which deliver a good balance of rigidity together with excellent shock
absorption characteristics.
In order to achieve good cushioning performance as well as accurate feedback
from the road surface, these new smooth-action forks feature an aluminium upper
triple clamp and a forged steel lower triple clamp.

Monocross rear suspension

A lightweight and compact new Monocross rear suspension system is fitted to
the XJ6 Diversion, and, like the midship muffler, it plays an important role in
helping to centralize mass and ensure easy handling characteristics.
This proven system features a new rear shock that is designed to give a
smooth ride together with class-leading roadholding, making the XJ6 Diversion a
strong performer in virtually every situation.



New lightweight cast wheels

Yamaha's engineers have gone to great lengths to centralize mass with the use
of lightweight components, thereby ensuring that the XJ6 Diversion delivers
responsive and enjoyable handling performance.
The newly-designed lightweight cast aluminium wheels deliver an optimum
balance of strength and rigidity, and their low weight also enhances the front
suspension performance by minimizing unsprung weight. Their lightweight design
also optimizes the gyroscopic moment around the front of the machine, and this
contributes to agile and easy handling.
The new lightweight wheels are fitted with a 120/70-ZR17 tyre at the front,
and a 160/60-ZR17 rear tyre, and these radial tyres give high levels of
roadholding and traction.

Lightweight 520 chain

For reduced frictional losses the new XJ6 Diversion is equipped with a
lightweight 520 chain. This lighter chain helps reduce drag for the efficient
transmission of the engine's power to the rear wheel, and the new 520-compatible
front and rear sprocket designs also contribute to the reduced drag and
frictional losses. In addition, the XJ6 Diversion benefits from a smaller
diameter 17 mm rear axle for reduced unsprung weight, and all of these measures
make a significant contribution towards overall weight reduction.

Slimline box-section swingarm

The new swingarm is manufactured from box-section steel pipe which offers a
superior balance of rigidity. The bracket that supports the swingarm is located
inside the swingarm, and this feature makes for a slimmer body design.

Lightweight and superior feeling brake system

Further weight savings can be seen in the front brake system, which consists
of dual 298 mm diameter discs. Compared to the FZ6, the XJ6 Diversion's discs
are 0.5 mm thinner, giving an unsprung weight reduction of about 180g overall,
and the twin-piston calipers are equipped with new hoses which feature an
optimized coefficient of expansion, giving enhanced operation and feel.
The 245 mm diameter rear disc is slowed by semi-metallic pads which are
designed to offer smooth braking for easy controllability. The rear braking
system also features a special relationship between the rear brake pedal lever
ratio and the return spring, where the spring rate has been specifically chosen
to allow the rider to generate braking power that is in direct proportion to the
amount of brake pedal depression.

ABS anti-lock braking system

The new XJ6 Diversion is also available with a compact new lightweight ABS
design. This new system has been developed to offer improved feel when
activated, and features a linear control (3-position) ABS, instead of the
previous two mode system, which operated in 'increased brake pressure' and
'decreased brake pressure' modes.
With the new linear ABS, the brake system's hydraulic pressure is
instantaneously varied according to the slip ratio of the wheels, and this gives
a smoother and more stepless feel when the system is activated. The new system
also gives a more natural feel to the braking system when the ABS is not
functioning.
New magnetic sensors are used in place of the previous system's sintered
alloy. Overall the new ABS unit and the front and rear sensor rotors give an
unsprung weight reduction of 1,320g.

Timeless next-generation pleasure-sports styling

The styling on the new XJ6 Diversion is designed to capture the spirit of
this outstanding new motorcycle, which can be summarized as being 'a pleasure
sports model with brisk performance that can be easily handled'.
For added wind and weather protection the XJ6 Diversion benefits from a
lightweight half cowl which gives the bike a sleek and sporty profile.
The three key themes which the styling aims to convey are:

Rider-friendly engine and chassis performance

Real-world middleweight

Timeless and exciting design
Two of the most significant aspects of the new XJ6 Diversion's body design
are the minimalist tubular steel frame, and the slimline swingarm which features
an inner-bracket layout. These structures are the main influence on the look and
character of the bike - from whichever angle it is viewed - and their design is
complemented and reflected in many other components, creating a unique and
original appearance for this next-generation middleweight.
The short midship muffler accentuates the feeling of the bike's strong
concentration of mass, which is further emphasised by the slim swingarm and
lightweight front and rear wheels. With its hexagonal shape, the narrow-waisted
fuel tank looks special from every angle, and the flowing tubes on the
minimalist diamond-type frame blend with the rest of the machine to give the XJ6
Diversion a very attractive, timeless and stylish appearance.

New instrumentation

Complementing the exciting and timeless styling of the new XJ6 Diversion is a
comprehensive new instrument panel featuring a digital speedometer, analogue
tachometer, odometer/tripmeter, fuel gauge, and a coolant temperature gauge.
