Suzuki Boulevard S50 (VS800 Intruder) 2005-2009 Review: The Agile Cruiser That Defies Expectations

Introduction

The Suzuki Boulevard S50 (marketed as the VS800 Intruder in earlier years) represents one of the most compelling entry points into the cruiser world. Produced from 2005 to 2009, this liquid-cooled V-twin strikes a rare balance between classic styling, approachable ergonomics, and surprising agility. While cruisers often prioritize aesthetics over dynamics, the S50 delivers a ride that feels refreshingly alive beneath you. After spending time with a well-maintained 2008 model, it’s clear this motorcycle deserves more attention than it gets in the shadow of its larger Boulevard siblings.

Design & Aesthetics: Classic Lines With a Modern Twist

At first glance, the S50 leans into traditional cruiser DNA with its teardrop fuel tank, raked-out front fork, and acres of chrome. The 45-degree V-twin engine dominates the profile, framed by a narrow double-cradle steel frame that gives the bike a lean, almost bobber-like stance. Chrome accents on the exhaust, engine covers, and handlebar brackets catch the eye without venturing into gaudy territory.

The 19-inch front and 15-inch rear spoked wheels add a retro flair, while the low-slung seat (700 mm / 27.6") creates an accessible riding triangle. Suzuki offered the S50 in subdued colors like Onyx Black and Titanium Silver, but it’s the occasional pop of Candy Daring Red or Pearl Nebular Black that really makes the design sing.

Where the S50 surprises is in its details: flush-mounted turn signals, a hidden tool compartment masquerading as an air filter cover, and a tail section that tapers neatly into integrated LED lighting (ahead of its time for mid-2000s cruisers). The analog speedometer is clean but could benefit from a gear position indicator—a common omission in this class.

Engine & Performance: The Sweet-Spotted V-Twin

Specs at a Glance
- Engine: 805cc liquid-cooled 45° V-twin
- Power: 50 HP @ 6,500 RPM / 47.9 lb-ft torque @ 5,000 RPM
- Fuel System: Dual Mikuni BDS36 carburetors
- Transmission: 5-speed with shaft drive

Suzuki’s 805cc mill is the star here. Unlike air-cooled competitors that bake your shins at stoplights, the liquid cooling system keeps heat manageable during summer crawls through city traffic. Thumb the electric starter, and the engine settles into a relaxed 1,100 RPM idle with just enough lope to announce its cruiser credentials.

Low-End Grunt Meets Refinement
From 2,000 RPM upward, torque builds linearly, peaking with a satisfying shove between 3,500–5,000 RPM. The 5-speed transmission shifts with a positive click, though the cable-actuated clutch requires more effort than modern hydraulic units. Shaft drive eliminates chain maintenance but introduces slight driveline lash when rolling on/off throttle abruptly.

Real-World Riding Impressions
- City: The 443 lb (201 kg) wet weight and narrow profile make lane splitting easier than any cruiser this side of a Honda Rebel.
- Highway: Stable at 70 mph (113 km/h), but the 2.5-gallon (9.5L) tank demands frequent stops on long hauls.
- Backroads: Rev it out to 6,500 RPM, and the engine note transitions from bassy rumble to a metallic howl—more engaging than typical cruiser acoustics.

Carburation is generally crisp, though cold starts require patience. An aftermarket fuel controller (available at MOTOPARTS.store) can optimize mixture for aftermarket exhausts.

Handling & Comfort: Where the S50 Shines

Suspension Setup
- Front: 41mm telescopic fork (130mm travel)
- Rear: Twin shocks with 5-position preload adjustment (90mm travel)

The S50’s 61.4-inch (1,560mm) wheelbase suggests stable cruising, but the geometry has a secret: 33° rake and 5.7 inches (145mm) of trail create quicker steering than rivals. Flicking through canyon switchbacks reveals shockingly neutral manners—no wrestling the bars mid-corner.

Braking
- Front: 275mm disc with twin-piston caliper
- Rear: 130mm drum

The front brake delivers adequate bite, but the rear drum feels vague. Swapping to sintered pads (find them here) improves initial response. ABS wasn’t offered, so threshold braking skill is essential.

Ergonomics
The pulled-back handlebar and forward pegs create a relaxed posture. The thinly padded seat becomes firm after 90 minutes—an ideal excuse to browse our selection of gel seat pads. Wind protection is minimal; add a quick-detach windshield for highway comfort.

Competition: How It Stacks Up

1. Honda Shadow Spirit 750

• Pros: Larger 3.7-gallon tank, lower seat height
• Cons: Air-cooled engine runs hot, softer suspension
• Verdict: Better for straight-line cruising; S50 wins in corners

2. Yamaha V Star 650 Classic

• Pros: Belt drive (quieter than shaft), more aftermarket support
• Cons: 30% less torque, heavier feel
• Verdict: S50 offers livelier performance

3. Kawasaki Vulcan 500 LTD

• Pros: Parallel-twin engine revs freely, 6-speed gearbox
• Cons: Lacks V-twin character, cheaper finishes
• Verdict: Sportier alternative; S50 has better low-RPM manners

The S50’s Edge: Unmatched agility in its class, with a liquid-cooled engine that shrugs off traffic jams. Downsides? Smaller fuel tank and dated rear brake.

2. Shaft Drive: Replace gear oil every 24,000 km (15,000 miles).
3. Valve Clearance: Check every 12,000 km (7,500 miles)—shim-under-bucket design requires patience.
