The T-Max is Yamaha’s twist ‘n’ go
“Super-Scoot” and is aimed at the commuter who not only has to go that little
bit further, but also wants a bike that can do the longer weekend trips and
handle motorway cruising and carry a pillion without having to get off and push
the thing up hills!
First Impressions
Its big and it’s long. The tall screen and the large black
fairing around the headlamps makes the front look very bulky. Head-on it looks
like a black and silver brick. It’s not brilliantly aesthetic but at least it
looks as though it means business when it appears in the rear view mirrors of
cars. The rear end treatment is smooth and sleek by comparison. Pearlescent
silver paint looks great but could be easily marked by boots – especially
pillions. Subdued contrast with silver middle panels. Has a refined and solid
appearance.
Practical Bits
There’s a useful cubbyhole with lid in the right front fairing
for sunglasses, coins, etc. Why not a second one on the left? There must be
enough space within all that plastic. The ignition lock also operates the seat
lock which rises on a hydraulic strut to reveal a storage space large enough to
hide a small child! And it’s illuminated and has a removal carpet liner. How
cool is that?
A hinged flap at the front of the seat opens for access to the
lockable petrol cap.
There’s both a side stand and a centre stand. The bike is easy
to get on to the centre stand but tricky to get off when you’re seated on the
bike as the seat width prevents you getting a good leverage to pull the bike
forward. It’s best to get off the bike and use the left bar and grab rail.
Getting on it
Seat is wide, unless you sit well forward, and although the
seat isn’t that high it’s not that easy to get both feet flat on the ground.
There’s an adjustable bum-pad for the rider and plenty of space behind that for
the pillion, who has both side and rear grab rails and reasonably well-placed
pegs.
Bars are wide and nicely positioned for manoeuvring through
traffic and give a relaxed riding position. All the usual controls are in the
usual places and the analogue instruments are clear and easy to read.
Starting it
Couldn’t be easier. Turn the key, pull in the rear brake lever
and press the starter button. The parallel twin rumbles into life and
immediately settles into a steady tickover. Surprisingly, the engine is still
carburetted, but the automatic choke works well and you can pull straight away
from cold without having to wait for things to warm up. A twist of the throttle
and you’re away.
On the move
The automatic belt transmission works well with the throttle
control to give a smooth snatch-free ride, even at partial throttle openings.
There’s no jerkiness so manoeuvring in traffic is a doddle. But you need to
remember that The T-Max is pretty long and wide by normal scooter standards, so
getting through those small gaps isn’t going to be quite so easy, even though
the wide bars and the excellent lock do help here. Where the T-Max will top just
about anything on wheels is at the lights. From a standing start there’s nothing
on wheels to beat it. Just give it a big right handful, hang on tight and it’s
off like a ferret up a drain pipe! The long wheelbase and the low centre of
gravity (the engine’s mounted horizontally under the seat) means that there’s no
chance of a wheelie – just total forward motion.
Due to the lack of a reasonable straight I wasn’t able measure
top speed, but I did see an indicated 92mph at one point before I had to back
off for the next corner. I expect it would top out at around the ton. The good
thing was that even at this speed the bike felt composed and stable and I was
always able to feel what both wheels were doing.
As you’d expect from a scooter, especially one with a screen
this tall, weather protection is good. On the move the large front fairing and
tall screen keeps most of the rain at bay, and the waterproofs can stay packed
away. However, once you stop . . . . . The other thing that you might expect ,
given the size of the fairing, is a certain degree of buffeting from the other
vehicles and crosswinds. But you’d be wrong. Following lorries is not a problem
and even a blustery day did not upset the T-Max one bit. The fairing may be big
for a scoot, but it does work.
The suspension is surprisingly firm and well damped. The ride
is handled by twin telescopic forks at the front, and a double-sided rear swing
arm that incorporates the belt and final drive and pivots on the engine
crankcase. The rear spring unit is mounted horizontally under the engine and
unusually works in extension. Good grip levels from the OE Bridgestones on
14-inch wheels mean that when the traffic thins out you can up the pace and wind
up the grin meter. This is a scoot that can be hustled through the bends and
twisties to such an extent that you will find yourself laughing hysterically
inside your helmet. Lean angles are only limited by decking the centre stand.
You will do this.
Forward motion is arrested by a single disc on both wheels,
with a two-pot sliding calliper at the front and a single-pot slider at the
rear. Both are seriously adequate with the rear only needing a single finger on
the lever. However, there’s also a lot of engine braking when you close the
throttle, which came as a surprise to someone who’d previously only ridden
2-stroke twist ‘n’ go scooters.
I only rode it in town at night, so I can’t make much of a
judgement on the headlights. However, dip beam gave a good spread pattern and
the instruments were well illuminated and easy to read. Main beam on the open
road is an untried quantity.
Niggles
The engine is a parallel twin, so it does vibrate. It’s not a
big problem, although it can be a little wearing on long runs. It’s something
you’ve just got to live with.
Something that I couldn’t live with though is the helmet
buffeting and wind noise from the tall screen. This starts at around 20 mph and
just gets worse as the speed increases. It’s so bad that I needed ear plugs
under a full face helmet to pop down to the shops and I’m a fraction under 6
foot. Ducking down a couple of inches and the noise vanished but the down side
was pain in the middle of my back and shoulders. There is an alternative lower
screen and I think it would be well worth fitting it if you are anything over
5'8"!
Conclusions
The T-Max is an excellent compromise for someone who needs two
wheels for serious commuting as well as a machine for longer trips at weekends.
But check for wind noise before you buy. Although it looks like a scooter, it
handles like a real bike and really comes into its own on B-roads. However, no
one on a conventional motorbike will acknowledge your existence.
