Suzuki GSR 750 BOSS 2014 — Specifications

Arriving late to the bustling middleweight streetfighter segment, the GSR 750 has nonetheless managed to carve out an enviable place against firmly established rivals. The 2014 model year confirms this upward trajectory, with a BOSS version that bets everything on visual theatrics to shake up a category where the eye counts almost as much as the spec sheet. Faced with a Kawasaki Z 800 that still dominates sales, the Suzuki remains one step behind, but easily outpaces its Gladius cousin in dealerships.

Beneath the 17.5-litre tank sits this inline four-cylinder of 749 cc, directly derived from the GSX-R lineage, a heritage felt from the very first turns of the wheels. The 106 horsepower peak at 10,000 rpm and the 79.4 Nm of torque at 9,000 rpm are figures in line with the segment average, but the engine's smoothness makes all the difference. The 72 mm bore for 46 mm stroke and a compression ratio of 12.3:1 betray its sporty DNA. On the scales, 211 kg wet, a contained mass that quickly melts away once the machine is in motion, with a top speed quoted at 220 km/h that is more than enough to recall the hyper-sport origins of the powerplant.

The perimeter steel frame receives a 43 mm inverted fork with 120 mm of travel, backed up by a rear monoshock offering 135 mm. Braking relies on two 310 mm front discs gripped by two-piston calipers, complemented by a 240 mm rear disc. It is decent, without being stunning, but consistent with the machine's versatile vocation. The seat height of 815 mm remains accessible, which is no small detail given that the segment targets both the experienced rider and the freshly unrestricted A2 licence holder.

This BOSS finish, unveiled as an exclusive at the 2014 24 Hours of Le Mans alongside the Gladius 650, borrows the dark and yellow livery lifted from the M 1800 R Intruder. The effect is sharp, almost cinematic, and pulls the machine towards a more prestigious stance. Suzuki adds a few useful trinkets as standard, a pair of bobbins, engine protection sliders, a revised licence plate holder, and specific footpegs for both rider and passenger. On the other hand, the superb Yoshimura R-11 exhaust and the matching seat cowl remain in the options catalogue, which stings a little when talking about a special series priced at 7,599 euros, with ABS optional on top of that.

For whom, then, is this GSR 750 BOSS ? For the urban rider who wants a versatile machine capable of stringing together weekends on backroads without running out of breath, and who appreciates being offered a paint scheme that stands out from the ambient grey of parking lots. Against the bulkier Z 800 and a Yamaha MT-09 more radical in its three-cylinder twin temperament, the Suzuki plays the card of mechanical wisdom, of a silky and linear four-cylinder, without surprising jolts. An honest, well-bred roadster that invents nothing but does everything correctly, and which this BOSS attire should help pull out of the pack in a category where differentiation is becoming the crux of the matter.
