For the first three model years of the Triumph Speedmaster cruiser, virtually no changes came from its manufacturer, British bike company Triumph Motorcycles. This is not the case with the 2005 edition. Triumph decided to up the ante by making some serious improvements to the engine. For the 2005 model year, Triumph set the manufacturer’s suggested retail price at $8,699.
The 2005 Triumph Speedmaster uses the same four-stroke, air-cooled, parallel twin engine for its power, with the same compression ratio (9.2 to 1), number of intake valves (eight, with four on each of the engine’s two cylinders), and two-carburetor fueling method. However, the engine is larger this time around. Gone were the days that it displaced at 790 cubic centimeters (cc); with the 2005 edition, it displaces at 865 cc. Also, horsepower (hp) and torque were increased to 54 hp at 6,500 RPM and 50.2 lb-ft of torque at 3,500 RPM. The engine is paired with a five-speed manual transmission, with an electric starter for convenient ignition. Peak fuel capacity on the bike is set at 4.4 gallons (16 liters).
The 2005 Triumph Speedmaster uses all-wheel disc brakes for its stopping power. They consist of a 12.2-inch (310-mm) dual disc at the front, and a smaller, 11.2-inch (285-mm) single disc at the rear. The suspension consists of a 1.6-inch (41-mm) telescopic fork and a twin-sided steel swing arm with two rear shocks. Fitted on each 2005 Speedmaster are front 18-inch and rear 15-inch aluminum wheels wrapped in tubeless tires.
Made of a steel frame and dressed up with minimum plastic, the 2005 Triumph Speedmaster is available in one of the three following color schemes: Jet Black, Jet Black/Neon Blue, and Jet Black/Tornado Red. On top of the bike is a one-piece vinyl seat for accommodating the driver and a passenger, and a kick stand below it serves as its parking device.
Instrumentation on the 2005 Triumph Speedmaster’s dashboard consists of a tachometer, trip odometer, and speedometer. Under-seat and lockable compartments serve as the bike’s storage space, and a halogen light and pair of rearview mirrors enhance the driver’s visual perception in adverse driving conditions.
Each 2005 Triumph Speedmaster has a length of 95.4 inches (2,423.2 mm), width of 33.2 inches (844 mm), height of 46.6 inches (1,184 mm), and wheelbase of 65.2 inches (1,655 mm). The seat on the bike is set at a height of 28.3 inches (720 mm). When dry, the 2005 Speedmaster weighs approximately 504 lbs.
The Triumph Speedmaster was already a good standard bike, with better-than-average performance and power. However, the tweaks made on the 2005 model year put it a few notches above the first three iterations.
