Fuel and Lubrication Requirements

The 2005 V Star 1100 is equipped with a 17-litre (4.5 US gallons) fuel tank, including a 4.5-litre (1.1 US gallons) reserve. It requires unleaded gasoline with a minimum Octane rating of PON 86/RON 91. While fuel variants containing up to 5% MTBE or 10% ethanol with appropriate additives are permissible, blends containing methanol are not recommended due to potential performance issues and fuel system damage.

For lubrication, the V Star 1100 utilises a wet sump system. The oil capacity is 3 litres (3.2 US quarts) for a standard oil change, increasing to 3.1 litres (3.3 US quarts) when the oil filter is also replaced. The final gear oil capacity is 0.19 litres (0.20 US quarts).

Yamaha recommends using SAE 10W-30 or 20W-40 Yamalube 4 motor oils that meet JASO T903 MA/MB standards with a minimum API grade of SJ. It's crucial to use oils without chemical additives, as they also lubricate the clutch assembly. Avoid oils labelled "Energy Conserving II" or those with a "CD" (or higher) diesel specification.

Drivetrain and Transmission

Power is transferred to the rear wheel via a reliable 5-speed constant-mesh manual transmission, operated by a left-foot shifter. The clutch assembly is a wet, multi-disc type, known for its smooth engagement. The final drive is handled by a shaft drive system, which is low-maintenance and contributes to the bike's overall clean appearance. The gearing is well-spaced to take advantage of the engine's strong torque curve, providing a responsive riding experience.

Ignition and Electrical System

The 2005 V Star 1100 employs a digital transistorized coil ignition system for reliable spark generation. Starting is facilitated by an electric starter. The charging system is powered by a triple-phase A.C. magneto. The bike is equipped with a 12V 12 Ah (10 HR) GT14B-4 battery, which powers the lighting and electronic accessories. When replacing the battery, the Yuasa YUAM624B4 YT14B-BS is a common and compatible option. It's important to note that the battery format used in the 1,300cc V Stars (Strykers) is incompatible.

Ignition is handled by an NGK BPR7ES or Nippon Denso W22EPR-U spark plug, with a specified electrode gap of 0.7–0.8 mm (0.028–0.031 inches) and a torque setting of 20 Nm (2.0 kgf-m, 14.5 ft-lbf).

Tires and Brakes

The 2005 V Star 1100 typically rolls on bias-ply tubeless tires: a 130/90 16MC (67S) at the front and a 170/80 15MC (77S) at the rear. These are usually mounted on 16M/C x MT3.00 and 15M/C x MT4.50 cast wheels respectively. Common tyre brands fitted as original equipment include Dunlop D404s or Bridgestone Exedra G702/3s, depending on the specific trim. Recommended cold tyre pressures are between 225–250 kPa (33–36 psi), varying slightly for solo or pillion riding.

For stopping power, the V Star 1100 features a triple-disc brake setup. The front brakes consist of twin-piston calipers acting on 298 mm discs, while the rear utilises 282 mm discs with similar calipers. This provides strong and reliable braking performance.

Suspension and Chassis

The motorcycle is built around a double-cradle tubular steel chassis with a 33° caster angle and 132 mm (5.2 inches) of trail, contributing to its stable handling characteristics. Up front, 41 mm telescopic forks with oil-damped coil springs provide 140 mm (5.5 inches) of wheel travel. At the rear, a linkage-type suspension system with oil-damped gas shocks offers adjustable preload and rebound damping, providing 113 mm (4.45 inches) of wheel travel.

The wheelbase measures a substantial 1,645 mm (64.8 inches), and the bike has a turning radius of 3.4 metres (11.1 feet). With a ground clearance of 140 mm (5.5 inches), the V Star 1100 maintains a low centre of gravity, enhancing its stability and reducing the likelihood of tipping.

Dimensions and Ergonomics

The overall dimensions for the Standard and Silverado models are approximately 2,460 mm x 945 mm x 1,095 mm (96.9 x 37.2 x 43.1 inches – Length x Width x Height). Custom trims are generally slightly shorter.

The curb weight of the 2005 V Star 1100 ranges from 285 kg (628 lbs.) to 288 kg (635 lbs.), with California models being marginally heavier. The saddle height is comfortably situated between 690–710 mm (27.2–28 inches), accommodating a wide range of rider heights. The maximum load capacity for the trims is between 200–203 Kg (441–448 lbs.), with a Gross Vehicle Weight Rating (GVWR) estimated between 485 Kg (1,069 lbs.) and 491 Kg (1,082 lbs.).

2005 V Star 1100 Trims and Styling

The 2005 model year was notable for Yamaha offering five distinct trims for the V Star 1100, deviating from the usual two or three. Each trim offered unique styling cues:

• Silverado: This top-tier trim featured studded leather saddlebags and seats, a backrest, chromed tank and fenders, and a windshield, signifying a more premium, touring-oriented package.
• Classic: Characterised by blacked-out engine and bodywork, a windshield, and studded leather seats and saddlebags (similar to the Silverado). It was also the only trim to offer a two-tone colour scheme in 2005.
• Custom: Distinguished by spoked aluminium rims, exposed front forks, a narrower front tyre, and a bobbed rear fender. It featured a peg configuration with a heel-toe shifter, unlike the floorboards found on other models.
• Midnight Custom: Similar to the all-black Classic, but without the windshield and studded accessories. Its front fender was also trimmed for a more streamlined look.

The overall design language of the V Star 1100, with its low stance, rounded edges, and elegant simplicity, made it a visually appealing motorcycle that appealed to both experienced riders and newcomers to the cruiser scene.

Common Issues and Owner Feedback

While the 2005 Yamaha V Star 1100 is generally a reliable machine, some common issues have been reported by owners:
