Overview
Imagine a machine that whispers promises of scorching asphalt and sidelong glances at traffic lights. Not just a custom, but a statement on two wheels, as if a dragster had seduced a chopper to give birth to this colossus. The Suzuki Intruder M 1800 R BOSS is exactly that: a total absence of compromise. With its 1783 cm3 breathing strongly in a 54° V configuration, it doesn’t focus on crazy numbers – 125 horsepower, which is almost modest on paper – but on monstrous torque of nearly 159 Nm available from 3200 rpm. That's where its soul lies: a visceral surge, a low-end traction that presses your shoulders against the tank without fanfare.

Its aesthetics are a knockout punch. The 2015 BOSS version plays with shadow and light with theatrical mastery. Everything is black, a deep black that swallows the light, from the engine to the calipers, including the inverted fork. Only a splash of bright yellow, like a tongue of fire, cuts through this bodywork. It’s aggressive, assumed, and it works. This motorcycle doesn’t go unnoticed; it imposes silence. With its 240 mm wide rear tire, it seems anchored to the road, a promise of stability that contrasts with its boiling temperament.
The road, just so, is its territory. Despite a confirmed weight of 347 kg fully fueled, it handles with surprising agility for its size, aided by a ridiculously low seat at 705 mm, which will inspire confidence even in the least experienced riders. The front end, serious, with its 43 mm inverted fork and radial brakes with dual 310 mm discs, inspires absolute confidence. Shaft drive transmission adds to this feeling of serene robustness, perfect for devouring long straightaways or negotiating curves with nonchalant authority. You’re far from the nervousness of a sportbike, but the top speed approaching 220 km/h reminds you that you don’t mess with it.
So, for whom does this Intruder run? Certainly not for the novice looking for a docile first machine. It’s the mount of the experienced epicurean, the one who prefers sensation to the stopwatch, presence to mimicry. At a price that hovered around €15,000 at the time, it positioned itself as a characterful alternative to the more polished productions from Harley-Davidson or Yamaha. It never sought popularity, contenting itself with being an icon for those who see the motorcycle as a raw extension of their personality. A drawback? Its thirst, with a 19.5-liter tank, could frequently remind you of its voracious appetite. But that’s the price to pay for riding a myth, a machine that is, more than a means of transport, a state of mind on wheels.
