Suzuki Intruder M1800r
The Suzuki Intruder M1800r has a top speed of 200 km/h (electronically limited; estimated, may vary), produces 127 hp and weighs 347 kg. Motoryk rates it 7.8/10.
The Suzuki Intruder M1800R (sold as the Boulevard M109R in North America) was introduced in 2006 as Suzuki's flagship power cruiser, featuring a massive 1783cc fuel-injected V-twin engine designed to compete directly with Yamaha's V-Max and Harley-Davidson's big cruisers. It gained a reputation for its aggressive styling, wide rear tire, and impressive low-end torque, making it one of the most powerful production cruisers of its era. The M1800R became a benchmark in the power cruiser segment and received updates over the years including the R2 variant with revised styling and equipment.

What Buyers Should Know
Rock-Solid Engine Reliability
The 1783cc V-twin engine is widely regarded as one of the most durable in its class, with many owners reporting 50,000+ miles with minimal issues when properly maintained.
Watch the Final Drive
The shaft drive system can develop leaks over time — always inspect the rear drive unit for oil seepage, as repairs can be costly if neglected.
Strong Resale Value
The M1800R holds its value better than many competitors in the cruiser segment, making it a smart buy used and a reliable resale if you decide to sell later.
Generations & Specs by Year
Introduced 1783cc V-twin, fuel injection, shaft drive, Boulevard M109R in North America.
"Muscle bike excess done with surprising Japanese polish."
That 1783cc V-twin pulls like a freight train from 2,500 rpm — you don't rev this motor, you just lean on it, and it responds with a wall of torque that shoves you back into the wide seat almost violently. Shaft drive makes it genuinely low-maintenance for long hauls, and the 700mm seat height is a genuine blessing for shorter riders who still want intimidating presence. The 347kg wet weight is not a suggestion — it's a commitment; slow-speed manoeuvring in car parks will catch you out more than once, and the wide bars only help so much. Fuel injection on this generation is well-mapped and crisp, but the cooling fins are mostly decorative — this is a liquid-cooled engine wearing a cosplay outfit, and it does run warm in slow traffic.
Pros
Cons
Revised fuel injection mapping, updated styling details, improved throttle response and minor refinements.
Euro 4 compliance updates, revised exhaust system, minor cosmetic and emissions-related changes.
Used Buyer Review
"A genuinely serious cruiser that rewards riders who actually ride."
$6,500-$11,000 usedThe M1800R is Suzuki's answer to the big V-twin cruiser wars, and honestly it's a compelling one. That 1800cc motor is the real deal — smooth, torquey, and genuinely impressive pulling power from almost any rpm. It doesn't feel like a poseur bike. It feels like a motorcycle that wants to actually be ridden hard on a canyon road, not just parked outside a diner. The riding position is relaxed without being completely reclined, and the chassis handles better than the sheer size suggests it should. Buying used, watch the final drive — these shaft-drive bikes can develop clunks if serviced poorly. Also check the fork seals and give the throttle bodies a good look; lean surging at low speeds is a known grumble. Parts availability is decent but not great at independent shops, so factor in dealer costs. Models from 2012 onward got refinements worth seeking out. Budget for a proper service regardless of claimed history.
