Road test by Adrian Percival
After riding an 2004 R1 for the previous couple of weeks in all
sorts of conditions and types of traffic I had an opportunity to
swap over for a while onto the new Yamaha XT660X Supermoto. So
with some reservations I headed off on a sunny day to Brooklands
in Surrey to change bikes. Now Brooklands is just off the M25 so
it's inevitable that you will have to use some of this horrible
motorway to get there, but with traffic the way it was and the
road repairs on the main motorway I was glad in a way that I
used it as all the smaller roads seemed to be in a state of
gridlock!
I collected the XT and was reliably informed 'No don't use it on
the motorway, take the twisties!', but with what I had just
ridden through I decided to take the M25 back for a short way.
After checking over the bike and the controls I headed off
through the town and back toward the motorway, and with just 5
miles under my belt a switch went on in my brain - I had just
turned into another type of hooligan - this bike is great, it's
the kind of bike that every motorcyclist should own, a bike for
all weathers and it just makes you smile...
Riding through the traffic is so easy, and as I passed yet
another supersports bike with the rider all hunched up painfully
over the bars I though of myself a short while before! Riding
the same route on the R1 was not nice, but on this XT it was
fantastic, let's see how it goes on the motorway coming up
next...
The Yamaha XT660X seems to eat up most types of traffic and
roads, it's versatile and easy to ride, you can have as much fun
as you can possible have on any bike riding at normal speed
limits and keeping your licence safe. For 2004, the XT660 has
been completely redesigned and now features a liquid-cooled,
single-cylinder motor with a 100mm bore and 84mm stroke. The
motor also features a forged piston running a compression ratio
of 10:1 in a ceramic-composite plated bore. A new fuel injection
system with a 44mm throttle body feeds the all new SOHC,
four-valve cylinder-head, and twin big-bore exhausts let the
engine breathe nicely.
The power delivery from the XT is very snappy indeed, the torque
delivery is pretty flat and that just encourages you to get
aggressive on the acceleration out of corners. You can get all
the power available down onto the ground without any real fear,
in fact I had the rear sliding out of corners after a while
(which I don't usually do!) under full control and had no worry
about Mr Highside paying me a visit. This bike seems to handle
all types of roads and every type of road surface you care to
throw at it, it stable on fast roads and will tackle motorways
for reasonable distances at well more than the legal limits. Not
only that but as far as motorway riding is concerned I did
discover that it is pretty resistant to buffeting from trucks
and buses making it an easy bike to commute on. I did do a bit
of commuting with it into London for a few days, and as a test I
only used the M40 motorway from Oxfordshire to get into the
city, it was easy and comfortable. The XT 660X is definitely the
sort of bike you could ride every day, and you could have your
dream bike sitting in the garage for those other special days.

The XT660 gives you the feeling that it is unbreakable when you ride it, it's an undemanding bike to ride but it has a very distinct road presence, but as always you will really have to ride one to understand what I'm talking about. On country roads and twisting 'A' roads it can be pushed as hard as you like into corners and leaned as far over as any current sportsbike without any fear, I did actually manage to touch a peg down at one stage which can't be bad from a bike derived from a dirt bike. There are a lot of lightweight dirt bikes that feel very nervous and skittish on the road, but the XT660X feels more like a normal middleweight naked road bike in reality, you don't get that feeling of vagueness from the steering and with the seating position and footpegs being as they are it gives you a much more sporting position than the usual dirtbike style layout. As I said before the power delivery comes in a way that plants the rear wheel on the road from very low revs right up through the range, it's much smoother and crisper than the normal big-bore enduro and very exhilarating in the mid range.
The XT uses a tubular steel frame
with two upper frame tubes, the engine is utilised as a stressed
member, this results in a chassis some 60% stiffer than its
predecessor, so Yamaha say. Both the XT660 and the X have the
same 43mm front forks, but the 660X is by far better on the road
due to being less soft and better damped. To complete the road
package the X has some excellent Excel road rims fitted, the
front and rear 17" rims run sticky 120/70 and 160/60 radial
tyres. In the braking dept the front is fitted with a huge 320mm
floating disc and a Brembo four-piston caliper, the combination
certainly works well and will haul you and the rear wheel up
very quickly indeed! Yamaha have tuned the suspension for the
XT660X and it works well, It's not just a dirtbike with road
wheels and tyres fitted, it's a total package. With the right
rider on it you will definitely surprise a lot of supersports
bike riders on any country road pursuit, not bad for a 48bhp
bike!
If you take a look at the Yamaha XT660X on the spec sheet then I
doubt very much whether you would consider it. On paper the XT
factory supermotard doesn't look that good, it weighs pretty
much the same as the current R1 and has between 1/4 and 1/3rd of
the power!! The single cylinder motor develops a meager 48bhp
and has to pull along a mass of 170kg (dry), it all looks like a
bike that will never thrill and have no performance at all. But
ride one and think again..the XT660X will change your opinion of
this type of bike, after a few minutes riding it you will soon
realise that the fun factor is high and the reason for this
is...you just ride it on the stop everywhere you go, corners
become a thing of the past and you just grin like a maniac!!

The XTX is a really easy bike to
ride through traffic and the city, and it's serious fun winding
country lanes, in fact the narrower the roads the better the XT
gets! With the super sticky sports road tyres, which are
incidentally designed for much more power, you can put down all
the power and lay it over as far as you like. Ride the XT at any
corner and keep the throttle open like you would on the dirt, it
will steer quickly and precisely around and accelerate hard out,
it great fun and I don't know of many other bikes that you can
actually do that with! The suspension soaks up all of the bumps
and undulations in a nice way without throwing the bike
off-line, and when you brake a little hard it doesn't dive
excessively. It's a different sensation completely to that of
riding a middleweight bike hard, a lot of this is due to the
relatively high seating position. Never think you will
overstretch this bike, keep the throttle open and keep your
weight over the bars, if you think you are going too fast or are
over committed into a corner then back it off a bit, the XT
won't bite back, then try again and lean it into the corner as
much as you like, it will take it believe me!
The XT660X is a bike you can live with every day. It's not some
highly strung supermoto that needs servicing daily, it doesn't
vibrate you off the bike on every ride either, you can actually
see through the mirrors at speed, and it's comfortable for
reasonable distances. It has all the benefits of a normal road
bike including (a bit of overkill in reality) hazard warning
lights! On a Supermoto!! No it really is a bike for everyone,
you can ride it to work and you can take on the big boys at
weekends, and that says it all in a nutshell...
