Yamaha Motor Australia has released an all new version of its
legendary XT250 that takes the lightweight and easy to ride on/off
road model to the next stage of excellence.
The engine boasts strong, usable power across the full rpm
range, with especially strong torque in the low- to mid-speed range
to improve trail riding performance as well as offering a new level
of comfort and enjoyment in around-town riding.
In addition to the universal ideals of light weight, slim feel
and compactness, the body built around its semi-double cradle frame
has been designed for optimum concentration of mass and lower
centre of gravity for ideal overall machine balance.
Engine capacity is increased from 223cc to 250cc and the new
engine is mounted in a new-design frame that features less unsprung
weight thanks to lighter wheel assemblies to achieve a big boost in
riding enjoyment, running speeds and stronger off road
performance.
The new model sports a 249cc air-cooled, 4-stroke, SOHC,
2-valve, single-cylinder engine. The bore has been expanded to
create short-stroke cylinder dimensions of 74.0 x 58.0mm, and with
a compression ratio of 9.5 to 1 the new engine produces both more
power and more torque than before. Strong torque and sharp response
characterises this engine across the entire rpm range.
Features like a lightweight forged piston and a plated cylinder
with excellent heat-dissipation characteristics contribute to the
powerful torque across the entire rpm range.
A 33mm diameter vacuum type carburettor is adopted with
optimised settings that clear the latest emissions standards. To
achieve an ideal balance with the 249cc displacement, the inertial
mass of the crankshaft has been reduced slightly. The ratio between
the exhaust volume and the inertial mass of the crankshaft (VI
ratio) has been lowered compared to the existing XT225 from 0.38 to
0.32. This has helped achieve outstanding ease of use, even at
walking speed and excellent drivability in the mid- to high-speed
ranges.
Improved mass concentration means a lighter feel and better
handling, which is the goal of the new-design semi-double cradle
frame. Compared to the existing model, the rigidity balance of the
frame has been optimised with slightly higher lateral and torsional
rigidity.
The newly designed front suspension features inner tubes with
strategic reduction of tube wall thickness and outer tubes with a
tapered design. Plus the adoption of a lightweight aluminium
under-bracket and a lightweight design for the meter assembly help
achieve a big weight reduction in the handlebar assembly. The
combined effect of these measures contributes to lighter handling
as well as outstanding cushioning effect. Front wheel travel is a
full 225mm.
For the rear suspension a bottom linked type Monocross
suspension with an aluminium cylinder in the shock unit is adopted
for lighter weight and good heat dissipation characteristics. This
suspension provides a soft cushioning feeling in the early and
middle stages of compression when the stroke is shorter and a
gradually stronger, more resistant cushioning as compression
approaches full stroke. This creates a more comfortable ride and
lighter, more agile machine. The wheel travel is a large 180mm.
The front brake adopts a 245mm disc and an asymmetrical 2-pot
caliper. The overall rigidity of the system has been optimised from
the pad material to the rigidity of the brake hose in order to
achieve good braking power and improve modulation. The rear brake
adopts a 203mm disc instead of a drum brake. The master cylinder of
the rear brake is designed in a single unit with the sub-tank to
contribute to better concentration of mass.
The headlight mounts a lightweight halogen light (60W/55W) with
a 133mm diameter lens. Also, a speed sensor type multi-function LCD
digital speedometer (including clock, twin tripmeter functions) is
adopted. The green background lighting of the meter panel ensures
good visibility at night as well as in the daytime. These features
further contribute to the lightness of the new front assembly
design for lighter handling.
The new design carries on the XT identity with a look defined by
a solid sense of core in the central mass of the machine and
peripheral parts that display a good sense of sharp
compactness.
The fuel tank is increased to 10 litres capacity while the
shroud portion is defined by a smooth sense of connection to give a
look of compactness to the exterior.
The maximum turning angle of the handlebars is close to that of
a trials bike at 51° and this combines with the short 1,360mm
wheelbase to provide a tight turning radius of 1.9m for extra
manoeuvrability.
Other features include an air induction (AI) system for cleaner
exhaust emissions, adoption of a spark arrester in the muffler and
retractable brake and shift pedals.
The 2008 XT250 is available now in Arctic White for just $6499
and comes with a full 24 month, unlimited kms, parts and labour
warranty.
2008 XT250 Key Features:
|
- For 2008, a bigger engine and extensive upgrades take the XT to
the next level of fun and all-around function.
- All-new styling including a bigger gas tank reinforce the
XT’s looks and performance.
- Long-travel suspension and over 285mm of ground clearance live
under a seat only 805mm from the ground.
- Electric start makes firing up the larger 249cc four-stroke
effortless.
- New, 245mm front disc and 203mm rear disc brakes combine to
deliver superb stopping power on both paved and unpaved
surfaces.
|
Engine:
|
- New 249cc air-cooled four-stroke with 9.5:1 compression makes
maximum power at 7500 rpm and maximum torque at 6500 rpm for great
on- and off-road performance.
- A light-and-strong forged piston inside a plated cylinder helps
dissipate heat more efficiently, increasing both performance and
durability.
- New 33mm vacuum-type carburettor keeps the airflow up for
excellent performance and throttle response.
- A lightened crankshaft helps provide quick responsive
power.
- Wide-ratio five-speed transmission for maximum power and
performance in a wide range of terrain and conditions.
- Hassle-free pushbutton electric starting adds extra convenience
and reliability.
- Engine is mounted high in the frame to provide an incredible
285mm of ground clearance.
- Automatic cam chain tensioner means minimal maintenance and
longer engine life.
|
Chassis/Suspension:
|
- A new-design semi-double-cradle steel frame achieves a lighter,
nimbler feel through greater mass centralization. Greater lateral
and torsional rigidity and reduced weight of the lower frame parts
help produce light, stable handling.
- A new front fork with 226mm of travel and revised damping soaks
up the rough stuff, both on-road and off. A new aluminium lower
triple clamp keeps the weight down.
- Maximum turning angle of the handlebar is 51
degrees—almost like a trials machine. Combined with a short
wheelbase of only 1,360mm, the XT250 has a super-tight turning
radius for excellent manoeuvrability.
- A new rear shock provides 180mm of wheel travel through a
progressive, Monocross-style linkage system for a smooth ride.
- 21-inch front and 18-inch rear aluminium wheels are extremely
durable and reduce unsprung weight for enhanced suspension
performance and handling.
- New 245mm front disc and 203mm rear disc brakes combine to
deliver superb stopping power on both paved and unpaved
surfaces.
- 285mm of ground clearance means you’ve got serious
off-road capability, and a heavy-duty aluminium skid plate adds
protection.
|
Additional Features:
|
- New multifunction digital LCD instrument panel with cool green
background lighting is easily visible day or night. It also removes
