For the 2005 model year, the Triumph Speed standard motorcycle from British manufacturer Triumph Motorcycles was split into two models: the Speed Four, introduced in 2002 and named after the number of cylinders on its four-stroke liquid-cooled horizontal in-line engine; and the older Speed Triple, which made its debut in 1994 and is also named after its number of engine cylinders. Triumph gave these models MSRPs (Manufacturer’s Suggested Retail Prices) of $6,499 and $9,999, respectively.
The engine on the Speed Four displaces at 599 cubic centimeters (cc), and generates 97 horsepower (hp) at 11,750 revolutions per minute (RPM) and 51 pound-feet (lb-ft) of torque at 10,500 RPM. The engine on the Speed Triple is much bigger and more powerful, displacing at 1,050 cc, and pumping out 128 hp at 9,100 RPM and 78 lb-ft of torque at 5,100 RPM. Moreover, the bore and stroke and compression ratio for the Four engines are 68 x 41.3 millimeters (2.68 x 1.63 inches) and 12.5 to 1, respectively, while that of the Triple are 79 x 71.4 mm (3.11 x 2.81 inches) and 12 to 1. Each engine has eight intake valves (four on each of the two cylinders, in a double overhead camshaft valve train) and is paired with a six-speed manual transmission. Each 2005 Speed has a gas tank with a peak capacity of 4.7 gallons (17.8 liters).
By this point in the Speed’s production cycle, the bike was using thick inverted forks combined with rear shock absorbers and aluminum swing arms (twin-sided on the Four, single-sided on the Triple) for better handling and smoother rides. Disc brake calipers – 12.2-inch (310-mm) or 12.6-inch (320-mm) dual discs at the front and 8.7-inch (220-mm) single discs at the back – form the 2005 Speed’s superb stopping system. Each bike rides on 17-inch aluminum wheels, fitted with tubeless tires.
While the Speed Four model of the 2005 Triumph Speed uses a Neon Blue color scheme, the Speed Triple sticks with a Jet Black finish. Both models adhere to a minimalist Triumph design plan: fenders and little else dress the Speed’s sturdy yet relatively lightweight aluminum frame. A two-piece vinyl seat – set at a height of 31.9 inches (810.3 mm) on the Speed Four and 32.1 inches (815.3 mm) on the Speed Triple – provided enough accommodation for the driver and one passenger. At the bottom is a kick stand for parking the bike.
A trip odometer, speedometer, tachometer, and temperature and fuel-level warning gauges constitute the digital instrumentation of the 2005 Triumph Speed. Also included are a pair of rearview mirrors, under-seat and lockable storage, and a halogen headlight.
The Speed Four model of the 2005 Triumph Speed has physical measurements that consist of a length of 81.1 inches (2,060.4 mm), width of 27.2 inches (690 mm), height of 45.3 inches (1,150 mm), and a wheelbase of 54.9 inches (1,395 mm). Moreover, its dry weight is estimated at 374 lbs. (170 kilograms). The Speed Triple is larger and heavier, with a length of 83.3 inches (2,115.3 mm), width of 30.7 inches (780 mm), height of 49.2 inches (1,250 mm), wheelbase of 56.2 (1,429 mm), and dry weight of 416 lbs. (189 kg).
With the advent of the 2000s, some enthusiasts feared that the Triumph Speed might be long in the tooth. For the most part, they thought wrong. Establishing itself as one of the most mechanically powerful and richly endowed standard bikes in the market, the 2005 Triumph Speed was now one of the more versatile ones as well: available in variants that appeal to less experienced riders and performance die-hards.
