environment may seem a little strange for a scooter supposed
to be used commuting in city traffic mainly, but partly, testing
of X-MAX took place on small country lanes in the hillsides of
northern Spain. Another rider carries on:" The X-MAX is
fun to ride on these small roads. What works well in these conditions
must be great to ride in urban traffic as well". He summarizes
the important elements behind the development of this new scooter:
The handling character was a key
issue in the engineering guidelines: X-MAX is supposed to submit
its rider a precise feeling for steering and cornering. The 15-inch
front wheel will respond directly to the riders input on the
handlebar, unlike other contenders in its class. There is no
"scooter like" spongy feeling in the handlebars when
manoeuvring the X-MAX. This is certainly beneficial on open roads
as mentioned above, but even more so in city traffic, where road
conditions with grooves and rough surface often direct the front
wheel into undesired directions. The X-MAX precise handling contributes
to a safer ride and one can pinpoint the riding direction when
filtering through urban traffic.
The X-MAX is another step towards a sportier and dynamic scooter,
the X-MAX chromosomes are made of technology inherited from motorcycles.
Its tubular steel chassis has increased rigidity comparing to
other contenders in the class. In alliance with a new front fork
and a new rear suspension, the stability of this new 250 machine
is outstanding in its class. When you can ride down the highway
at top speed (highest in its class with 125 km/h), this scooter
feels stable like a motorcycle going at the same pace.
Rider's comfort and sporty set-up
were no contradiction for the X-MAX project leader Takayoshi
Mizuno: "We targeted the best level of riding fun combined
with what you need for your daily commuting."
The roomy seat indeed offers enough comfort for the rider. The
rider's position is substantially different to comparable models.
In order to realise a rather short wheelbase and compact dimension
overall, the rider sits more upright. This contributes to an
active riding position enabling the rider to control the scooter
better, both in city traffic when manoeuvring through and at
higher speed on open roads.
The windscreen has been placed the nearest possible to the rider,
resulting in lesser air turbulence and therefore better protection.
The storage space under the seat is biggest in its class.
Unlike one would imagine in such a sporty chassis set-up, there
is a very roomy trunk space under the seat. Indeed the rider
could fit 2 full-face-helmets or other useful luggage. Since
the centre of gravity is rather low, even a full load under the
seat does not influence the handling significantly.
The X-MAX single cylinder four-stroke engine is one of the best
performers in its class. Based on the indestructible YP 250 engine
design, the new power plant has undergone several detail changes.
The guideline of development next to max power (20,1 HP) was
an excellent throttle response and acceleration. The drive train
has been modified to accommodate a larger 14-inch rear wheel,
contributing to the vehicle's dynamic stability.
The centre tunnel is not just
a styling feature with its frame like appearance, but accommodates
the necessary reinforcements and components to achieve the outstanding
chassis performance. The twin headlights look serious and provide
proper lighting necessary for daily commuting. The rear end looks
comparatively light and slim. This could be achieved since the
bulk of the storage space is located under the rider's part of
the seat, which contributes further to a neutral handling even
with storage space filled.
X-MAX did inherit technology from motorcycles, such as brakes,
frame and suspension components. And it has better riding characteristics
than average motorcycles not too long ago. At the same time it
offers more than enough comfort and storage space being a synthesis
of an enjoyable two-wheeler and a roomy and spacious commuter.
Here is the not so good news for us here in the USA: According
to Yamaha Europe there are currently no plans to bring the Xmax
to North America. That although is only the word at the moment,
not an irreversable decision for years to come. The fast growing
scooter market on this side of the Atlantic might make them change
their mind on this. If you seriously want an Xmax, contact the
guys at Yamaha Motor Co and let them know. For that, and of course
