Kawasaki VN 900 Vulcan Custom [2007-2012]: A Middleweight Cruiser That Punches Above Its Weight

Introduction

The Kawasaki Vulcan 900 Custom isn’t just a motorcycle—it’s a statement. Produced from 2007 to 2012, this middleweight cruiser carved out a niche by blending the laid-back attitude of a traditional cruiser with the agility of a modern street machine. With its 903cc liquid-cooled V-twin, belt drive, and fuel injection, the Vulcan 900 Custom became a benchmark for riders who wanted "big bike" swagger without the heft of a full-sized cruiser. Having spent time in the saddle of this machine, I can confidently say it’s a bike that rewards both new riders and seasoned enthusiasts with its forgiving nature and surprising versatility.

Design: Classic Cruiser Aesthetics with a Modern Edge

The Vulcan 900 Custom’s design is a masterclass in balancing nostalgia and innovation. Its double-cradle steel frame gives it a muscular profile, while the 21-inch front wheel and 180mm rear tire create a striking visual contrast that screams custom garage build. Chrome accents on the exhaust, air cleaner, and handlebars add just enough bling without crossing into gaudy territory.

The twin-valley fuel tank design is a subtle highlight, casting dynamic shadows that change with the light. Color options like Candy Sparkling Orange (Special Edition) and Pearl Purplish Black Mica give the bike a premium finish. Kawasaki’s attention to detail shines in elements like the “spool-style” cast wheels and the minimalist front fender, which keep the front end looking clean and uncluttered.

For riders under 5’7”, the 27-inch seat height is a godsend, offering confidence at stops. The forward-mounted footpegs and drag-style handlebars create a relaxed riding position, though the narrow “gunfighter” seat might have passengers begging for mercy after an hour.

Engine and Performance: Torque Is the Name of the Game

At the heart of the Vulcan 900 Custom lies its 903cc SOHC V-twin, tuned to deliver 78 Nm (58 lb-ft) of torque at just 3,500 RPM. This isn’t a bike that demands high revs—it’s all about low-end grunt. From stoplights to highway merges, the Vulcan pulls with a smooth, unhurried confidence. The fuel-injected engine eliminates carburetor fuss, firing up reliably even on chilly mornings.

The 5-speed transmission pairs seamlessly with the belt drive, offering buttery shifts and near-silent operation. While top speed hovers around 160 km/h (100 mph), the Vulcan’s sweet spot is cruising at 90-110 km/h (55-68 mph), where the engine feels unstressed and the exhaust delivers a muted burble.

Key engineering highlights:
- Liquid cooling with an automatic fan prevents overheating in traffic.
- Gear-driven balancer minimizes vibrations—a rarity in single-pin crankshaft V-twins.
- Dual throttle bodies with ECU-controlled sub-throttles for crisp response.

Handling and Ride Quality: Lightness in a Heavy World

Weighing 277 kg (610 lbs) wet, the Vulcan 900 Custom feels surprisingly nimble. The 33-degree rake and 1646 mm (64.8-inch) wheelbase strike a perfect balance between stability and maneuverability. In city traffic, the bike flicks through gaps with ease, while the 41mm telescopic fork soaks up potholes without drama.

The Uni-Trak rear suspension (adjustable for preload) keeps the rear planted, though it can feel stiff over sharp bumps. Braking is handled by a 300mm front disc and 270mm rear disc—adequate for casual riding, but spirited riders might crave more bite. Swapping to sintered pads (available at MOTOPARTS.store) is a worthwhile upgrade.

Comfort and Ergonomics: Built for the Long Haul (Mostly)

The Vulcan’s riding position is a study in cruiser ergonomics: feet forward, hands wide. The pullback handlebars reduce wrist strain, while the seat’s stepped design offers lower back support. However, the foam density leans toward firm—a common complaint that’s easily remedied with an aftermarket seat.

The 20-liter (5.3-gallon) fuel tank delivers a 250-300 km (155-186 mi) range, making it ideal for day trips. Wind protection is minimal, so installing a windscreen (check our Memphis Shades catalog) is wise for highway miles.

Maintenance: Keeping Your Vulcan in Fighting Shape

The Vulcan 900 Custom is notoriously low-maintenance, but a few key areas demand attention:

1. Belt Drive: Inspect every 8,000 km (5,000 mi) for cracks. Replacements like the Gates Carbon Drive belt are worth the investment.
2. Oil Changes: Use 10W-40 synthetic (3.2L with filter) every 6,000 km (3,700 mi).
3. Coolant: Flush every 48,000 km (30,000 mi) or 3 years.
4. Valve Clearances: Check every 16,000 km (10,000 mi)—0.10-0.15 mm intake / 0.20-0.25 mm exhaust (cold).
5. Tires: The stock 80/90-21 front and 180/70-15 rear favor style over grip. Upgrade to Metzeler Cruisetecs for wet-weather confidence.

Pro Tip: The stock exhaust’s catalytic converters can restrict airflow. A Vance & Hines Twin Slash system unlocks a deeper tone and minor performance gains.
