With the key words "a deeper and wider Sporty
models" for this model change, new technologies are adopted in all parts of the
machine, from the engine to component changes in the chassis. The main features
are optimization of the intake system in order to increase torque primarily in
the low- and mid-speed ranges, adoption of a fuel injection system which
contributes to great response and environmental friendliness, adoption of a
4-into-2-into-1 type exhaust pipe, adoption of a deluxe-model Öhlins rear
suspension (specialized settings), etc. The combined effect of these changes
gives the new XJR1300 an even sportier ride in a wide range of the use
conditions.
To achieve outstanding drivability an FI (fuel
injection) system is adopted. The intake valve operating characteristics were
also optimized and the combined effect of these changes have produced a roughly
10% increase in max. torque, from the existing 98 N•m to 108 N•m, while reducing
the rpm at which max. torque is achieved from 6,500 rpm to 6,000 rpm to give
this model a stronger torque character over a broader range from low speeds on
up. (*Figures for lead-free premium gasoline specification)
4-2-1 exhaust pipe and 3-way catalytic converter with oxygen
sensor feedback
A 4-into-2-into-1 exhaust pipe with a fresh new
shape has been adopted in order to bring out excellent torque characteristics.
Furthermore, it is outfitted with a 3-way catalytic converter (a device that
simultaneously oxidizes and breaks down CO, HC and NOx in the exhaust), and in
order to help the catalyzer function more effectively, an oxygen sensor is used
to detect the level of oxygen remaining in the exhaust and constantly feed back
that information to enable appropriate adjustment of fuel supply to achieve both
outstanding power output and environment-friendly performance (clears Japan’s
emissions regulation for 2007).
Deluxe Öhlins rear suspension with special settings
A rear suspension built by Swedish maker Öhlins
is adopted. This specialized unit is based on Öhlins’ deluxe model* twin-shock
suspension and has been given special settings in order to bring out a more
linear, direct handling feeling. (*As of Oct. 2006)
Other changes
Other changes include (1) new settings for the
front suspension, (2) the front and rear radial tires with special
specifications, (3) a new-design sheet, (4) new-design side covers, (5) new
handlebar position, (6) LED taillights with a fresh look and (7) quality-look
internal illumination for the meter panel, etc.
