If you were at the Timonium Motorcycle Show, you saw Pete’s Cycle’s
unveiling of the new 2016 Triumph Street Twin, a favorite at the show.
Hitting the sweet spot is one of the few clichés with which I can really
empathize. It’s that special moment when you know that God is in heaven and
that things have gone right – not just well, or good, but absolutely right.
The expression comes from tennis and describes the moment when the racquet
hits the ball in just the perfect place and the player places the shot exactly
where he wants it to be. You might not agree with lobbing to the baseline or
net but, as the point is won, you do have to stand back in admiration and agree
that it was done flawlessly.
Triumph has hit the same sort of sweet spot in terms of making a motorcycle
which is definitively perfect for its intended market place. As a Superbike
rider, you might think the Street Twin is grossly underpowered – but you would
be wrong to think of it as dull.
If you are custom cruiser fan you could say that the Bonnie is a bit of a
plain Jane. Clearly it isn’t a real classic bike – as witnessed by the fact
that none of the test bikes broke down and there were no pools of oil under the
bikes when we stopped for lunch either!
However, the 2016 Triumph Street Twin is a very clever motorcycle which
pulls off a rather smart trick. First, it is an authentic classic – but with
all the benefits of 21st century engineering.
It’s also Retro-chic in the manner of those blokes you see on the ads who
have forgotten how to shave and seem to be looking permanently into the
distance, trying to find the man bag they left on the designer park bench when
they were having a skinny latte with their Supermodel girlfriend. It will also
be the bike which launches a zillion custom bikes in the next twelve months
because it is crying out to be modified.
So, what is the Street Twin and why is it so important to Triumph?
First, it is vastly Triumph’s biggest ever engineering project and has cost
an immense amount of money. The bikes have also consumed a colossal amount of
engineering time and effort and this is very demanding for a company of
Triumph’s size. The Bonneville range has been four years in gestation and has
taken the full-time efforts of 50 engineers in the design team alone. Add to
this the production engineers and the staff designing the 150 accessories which
go with the bike and it becomes readily apparent that this was a motorcycle
which Triumph had to get right: being merely very good wasn’t going to be an
option.
The Street Twin is the first bike in what will be the all new Bonneville
family. It is the smallest capacity machine in the five bike lineup, but it is
wrong to think of the Street Twin as an entry level machine – a baby Bonneville
for those who can’t afford the real thing. It definitely isn’t!
One of the problems with the project is that the old T100 has been such an
immense success for Triumph, selling more than 141,000 units. I have never much
liked it, wanting something edgier from my motorcycling, but T100 owners
worship the bike – as do Triumph dealers.
So, the first target was two-fold and challenging. The new bike has to keep
existing Bonneville owners in the fold, while simultaneously giving them enough
reasons to want to upgrade to the latest offering.
The other problem is almost counterintuitive. The Bonneville name goes all
the way back to 1958 – arguably, in fact, to Mike Hailwood and Dan Shorey’s win
in the Thruxton 500 long distance race of June that year. On the way, it was a
Bonnie which did the first 100 mph lap of the TT by a road legal production
bike and became Steve McQueen’s favorite sportbike. You simply can’t mention
Bonneville without an avalanche of history tumbling down around you.
All this meant that there was a lot of pressure on the design team to make a
motorcycle which was honest – not just a plastic imitation of the
great-grandchild of the original Bonnie, like some fake, faded T-shirt with
artificial sweat stains, but a real, authentic, genuine item.
Clearly, the bike had to be a Parallel Twin. You could hardly have a
four-cylinder Bonnie, otherwise classic wrinklies like me would have marched
over to Hinckley and burnt the factory down. Equally clearly, the engine needed
to be compliant with all current and predicted emissions’ regulations.
Triumph’s solution to all these demands really is a lovely thing.
First, the new motor looks drop-dead gorgeous. It’s not a 1958 Bonnie, but
any proud grandparent would look at the widely splayed exhaust ports, with
their finned clamps, and the motor’s handsome angular lines and beam with
pride. “Oh yes,” they would coo, “that’s my lovely little lad, and doesn’t he
look just like his grandad?” – which, of course, is completely and wholly true,
because he does.
However, beneath the family good looks lies a very modern engine. The key
thing is that the new motor is partially water-cooled. This is essential so the
engine can be built to very tight tolerances to meet the regulators’ demands.
However, it is also genuinely air-cooled as well, so the radiator can be small
and unobtrusive.
With 900cc in the toy box, there was no need to tune the engine to the
ragged edge. Rather, Triumph could go for a single, overhead cam design but
with a unique form of eccentric cam to open the eight valves. The end result is
only 55 horsepower at 5900 rpm, but don’t let this lead you astray. It’s a very
torquey motor making 59 lb-ft of torque at a mere 3230 rpm, so in real-world
riding there is plenty of practical, useable power.
Using a SOHC design also makes the engine short – if you wanted to play
fantasy engine building you could almost pretend that it is a classic push-rod
motor – and this allows the fuel tank to be low in the chassis, making the bike
feel lighter than its already svelte 437 pound dry (198 kg). Mass
centralization is just as important for a Retro Bike as it is for a MotoGP
machine, and the bike really does feel very manageable.
What is clever are that the bits you don’t need to see are tucked away and
out of sight. Take the dreaded catalyzer as one example. Unless you are a
journalist poking around on a launch, you will never find the cat, it is hidden
so well beneath the engine.
However, you will see the lovely, brushed stainless twin exhausts. They
look, and sound, absolutely gorgeous, emitting a throaty rumble which would
grace any 1960s sporting Twin. Yet, the exhausts are completely legal because
of the way that exhaust noise levels are now measured, with the bike being
tested under acceleration. Done this way, the torquey low revving Triumph can
get away with making the sort of tenor music it should produce, rather than
being choked down to some sibilant rustling.
Triumph proudly revealed its Vance & Hines scrambler exhaust option to
the world press, and we were supposed to stand back in awe and admiration.
Well, I didn’t for sure. Instead of the authentic and delightful classic snarl
which the Street Twin makes as standard there is a deafening, not to say
discordant, racket which is 101% certain to alienate the general public.
Putting exhausts like this on a road bike is a pointless exercise undertaken
only by those who look at themselves in the morning and wonder: “Is that all
I’ve got to offer the world? I can’t ride to an even half-decent level, so I’ll
just annoy everyone by making the most possible noise for the least valid
reason.” Why Triumph is officially supporting the alienation of the
non-motorcycling population is a complete mystery to me.
This being 2015, the bike must have fuel injection and Triumph has
absolutely nailed this with perfect fueling from tickover all the way to when
the rev limiter kicks in at 7000 rpm.
The 84.6 x 80mm bore and stroke suits the engine perfectly. The cam profile,
which Triumph spent an inordinate amount of time developing, is right on the
money for its intended purpose.
The nasty, tooth-filling loosening vibes of the good old days – and they
really were bad – have been designed out by using a 270-degree firing
configuration and twin counter balancers. This is conventional, modern engineering.
But here’s where the plot gets really interesting. Triumph has done much
better than just ordinary, sound engineering. The motor does vibrate – but from
the firing impulses. You can actually feel the bangs, albeit discreetly and in
the background. They are a joy for anyone who really does believe in the
two-wheeled horse and wants to feel its heart beating. I loved feeling the
motor talking to me.
In real-world situations the power is ideal for its intended purpose, with
plenty of surge right from the moment the throttle is opened. The clutch is
sweet and light too, with no grabbiness, and the gearbox is positive with five
ideally spaced ratios. In fact, the whole package is so user friendly that you
could teach a new rider the first stages in the art of motorcycling.
Like the powerplant, the chassis is much cleverer than it looks. It’s a
steel, twin shock design, but with bracing tubes in front and behind the
engine. This gives a taut, tight, modern feel which is very comfortable for
another market sector which Triumph is trying to attract – the sport rider
tired of battling with 175 hp and the constant danger of having his license
suspended.
The front forks are excellent but if I owned a Street Twin the first change
I would make is to put some quality after-market rear shocks on the bike
because the standard Kayabas are only okay: nothing more.
The front brake looks incredibly modest with a single, 310mm disc gripped by
a Nissin 2-piston floating caliper, with ABS. Regardless of how it looks on
paper, this is a seriously good anchor and you will never need more power – no
matter if the Street Twin is fully loaded and carrying luggage. The rear brake
sort of works, and is clearly there for legal reasons, but it isn’t much more
than of decorative value.
The ergonomics of the bike are excellent – absolutely first class. The seat
height is low, and completely unintimidating, but the thin saddle is very
comfortable – surprisingly so. Julia LaPalme, one of my fellow journalists, was
kind enough to give me some key female data – because this is another market
sector Triumph is anxious to reach. Julia is 5’5” tall and has a 30-inch
inseam. She could place both feet on the ground without a problem. I am five
inches taller and there was still plenty of room for me, plus spare room to
stretch back. Anyone up to six feet and a bit will be fine. Overall, it is a
seriously thoughtful piece of design and shows the care Triumph has taken over
this project.
Within a few yards of setting off, you can’t help but like the Street Twin.
It’s eager to please right from the off and the bike is immediately involving.
Other than lacking a tail to wag, it reminds me of my much lamented Collie
bitch waiting by the back door when we were about to go for a walk.
There is a single, imitation analogue speedometer – it’s really electronic –
and discreetly hidden in there is information about average fuel consumption,
current fuel consumption and miles to empty. However, this is not a bike to be
ridden by playing about with electronic options. A Street Twin is more to be
felt, rather than commanded with a PlayStation controller.
The reality is the bike must, absolutely must, be ridden in the lovely area
between 3000 and 6000 rpm. Below 2500 rpm the motor is asking for a few more
revs to be comfortable, and if it is buzzed hard it starts to get all grumbly
and irritable. The Street Twin will manage nearly 50 mph in first gear, so it
is hardly an arthritic slug, but the motor doesn’t like these revs.
At the other end of the scale, one of the Triumph test riders told me that
the Street Twin would run up to 110 mph – but both he and the bike didn’t like
to be there. We ambled along at 80 mph on the Spanish four-lane highways and
the world was a wonderful place to be. Effortless, involving and graceful – a
true gentleman’s carriage.
The Street Twin is ludicrously light on fuel. Ridden very hard, as we did in
the morning test session, the bike returned 55 mpg. In the afternoon, riding
the bike as it will be used, 70 mpg was showing on the computer all the time.
For some reason I don’t fully understand, Triumph took us into the hills for
some seriously spirited riding. I can report with complete honesty that if you
want to ride the Street Twin like Malcolm Uphill’s 1969 Production TT-winning
Bonneville, then the bike is up to the job – as the wear on my toe sliders will
verify.
I rode in second gear, using the engine as a rear wheel brake, and I had a
great time. But I had even more fun riding back to the hotel at a far gentler
pace. With the big Twin burbling along at 3500 rpm (or so my bum mounted rev
counter reported back to me) in third and fourth gear, the Street Twin was a
lovely place to be and a wonderful reminder of why I am a motorcyclist and will
be until my dying day.
In conclusion, Triumph have done a quite remarkable job with the Street Twin
and have set the benchmark for this sector. It is now up to every other
manufacturer to play to catch up. And for those naughty, recidivist, classic
racers like me there is more to come from the Bonneville range with the launch
of the Street Twin’s big brothers in the spring. These are good times to be a
motorcyclist.
