Suzuki chose that moniker for its more modern and somewhat funky take on their long running and hugely successful SV650 middleweight.
Dynamically, the Gladius is not quite sharp enough to deserve being referred to as a sword, but it is a sweet ride.
Suzuki’s long running 645cc 90- V-Twin has proved successful beyond even their most optimistic bean-counter’s wildest dreams. In production now for well over a decade it has already earned a place in modern motorcycling folklore.
Big enough to offer a reasonable amount of grunt yet small enough to not suffer from the poor manners that a larger capacity would bring, it has proven a winning recipe.
The tweaked version in the SFV650 Gladius is by far the best yet. I am no stranger to this sweet little mill in all its previous incarnations but happily admit to being quite surprised at the pull of this latest example.
Only after feeling that difference for myself did I seek the technical documentation from Suzuki on the model, as I was eager to find out what had been changed to give the Gladius engine the significant shot in the arm I had clearly felt from the saddle.
Suzuki’s changes include a heavier crank to smooth low speed running and accentuate the engine’s v-twin character.
A switch to lighter valve springs, higher lift cams, dual-butterfly throttle bodies, different length intakes and exhausts for each cylinder, along with a new Idle Speed Control system that Suzuki is using for the first time, all add up to a significantly improved powerplant.
And I say significantly improved not from the press kit, but from my time in the saddle. Suzuki have made a real step forward with this latest engine and the quicker it filters down to the rest of the 650 range the better.
Shifting cogs on the Gladius is a sublime experience. A smooth clutch, perfect shift throw and engagement make shuffling up and down the box an absolute pleasure.
The exhaust system may follow the same lines as Suzuki’s other recent muffler styling disasters but what it lacks in aesthetics it makes up for in acoustics.
While being quiet enough to slip past the ADR noise meter it still manages to provide some aural pleasure, particularly on deceleration.
Clearly evident from my first stint on the Gladius was that it wore different brakes from its SV cousins. The front requires more effort at the lever than the SV bikes while the rear is much stronger.
A smaller master cylinder and caliper pistons on the front in comparison to the SV are a somewhat puzzling change.
Likewise the 20mm larger rear brake easily overwhelms the available grip and my first major stop when a road worker emerged with a stop sign from behind a car saw the back end slithering and sliding from side to side. Unfortunately Australia does not receive an ABS equipped Gladius.
The chassis includes a trellis frame suspended by preload adjustable 41mm forks and shock absorber. With three steps of the provided seven levels of available preload on the rear shock the rear suspension struggled to handle mid corner bumps while in the mountains.
Adding more preload largely cured it but if taking a Gladius home for good I would also experiment with lowering the forks through the triple clamps to give a sharper feel.
The instruments are clear and concise with a large conventional tachometer flanked by a bank of idiot lights on one side and LCD speedo on the other. A gear position indicator is also present.
In this day and age of Stalinist speed enforcement it would be nice if the speedometer was a little larger and more centrally located to the field of vision.
Ergonomically the Gladius proves quite amenable. I found the saddle reasonable enough for a largely painless 400km afternoon.
The small instrument binnacle seems to actually deflect some of the windblast and my Shoei ensconced bonce suffered no buffeting.
A 785mm seat height poses no problems for those of average height but shorties might prefer something a little lower.
The narrow girth will help the vertically challenged however. The mirrors work well and are largely devoid of vibration induced blurring.
Good grab bars are provided for the pillion and also double as secure anchor points for luggage. An optional top case mount adds to the luggage capabilities.
On a mixed highway and mountain run the Gladius returned 5.8 litres per 100km. Quite an admirable result as the engine and gearbox copped quite a workout on the tight cut and thrust that epitomises the well-worn run from Mansfield to Whitfield and back again.
The fuel light illuminated after 190km and I squeezed 11 litres into the tank at Mansfield. With 3.5 litres still in reserve it would have made for 250km to empty.
On the highway or in the city I am sure economy would fare much better extending the range further.
The Gladius comes in two versions. A full power unit, as tested, and a model eligible for learner riders through the LAMS scheme applicable in some states.
The LAMS version has top end power restricted by the ECU in order to meet the learner specified power-to-weight ratio, but still offers the ripper bottom end torque of the full power engine.
Both models are priced at $10,490 plus on road costs.
