Overview
Imagine a machine that doesn’t know how to speak softly. An engine that, as soon as it appears, imposes silence like a burst of air in a tea room. The Suzuki Intruder M 1800 R BOSS, that’s exactly what it is: an assumed stylistic exercise, a declaration of war on subtlety. With its 1783 cm3 V-twin, it lines up figures that sound like a challenge: 125 horsepower may seem modest on paper, but it’s its monstrous torque of 158.9 Nm, available from 3200 rpm, that defines its character. This force arrives low, very low, and slams you into the seat with the discretion of an uppercut. Faced with a Harley-Davidson Softail or a Yamaha VMAX of the time, it doesn’t play on the same register. It doesn’t purr, it rumbles; it doesn’t glide, it pulls.

Its aesthetics are a manifesto in themselves. The BOSS treatment, with its deep black cannibalizing frames, rims, and engine, is interrupted only by this bright yellow band, aggressive like a warning. It’s not a custom, it’s a dragster dressed for a funeral. The posture is radical: low handlebars, long wheelbase, and this 240-width rear tire that seems to want to swallow the asphalt. At a standstill, with its 347 kg fully fueled, it commands respect. But once in the saddle, the 705 mm height makes the beast surprisingly accessible, deceptively easy to tame at a walk.
Don’t be fooled by this accessibility, it’s a trap. Because when you open the throttle, the character of this big twin is revealed. Shaft drive transmission offers a certain progressiveness, but the power, channeled by a gearbox with only 5 speeds, tends to arrive in nervous bursts. It pulls like a draft horse, with a fury that recalls more the world of muscle bikes than that of traditional cruisers. On the open road, it can devour asphalt and brush against 220 km/h, but its favorite playground remains straight lines and killer acceleration. The braking, with its double 310 mm front disc and radial 4-piston calipers, is up to the mass to be controlled, offering a good sense of security.
So, who is this beast for? Clearly not for a beginner, despite its low seat. Its weight, its instant torque, and its physical behavior make it a demanding motorcycle. It targets the experienced rider looking for a raw alternative, less polished than a Harley, and more characterful than a classic Japanese custom. It’s the machine for those who prefer impact to understatement, a demonstration of force to finesse. At nearly 15,000 euros at the time, it was a bold gamble. A gamble that, like its lines, left no one indifferent. It was not reasonable, and that was precisely its whole interest.
