TRIUMPH Thunderbird Big Bore (2009-2010) Specs, Performance & Photos

In 2009, alongside the standard and SE models, the British motorcycle manufacturer launched the Triumph Thunderbird Big Bore, a cruiser motorcycle with a bored-out engine compared to the standard model.

The 2009 Big Bore, as its name says, received a larger bore with new pistons, liners, camshafts, and more powerful clutch springs to match the additional power and torque. In addition, the bike came with an exclusive Phantom Haze Red color scheme and optional accessories that made it stand out from the crowd even more.

In the aesthetic department, the 2009 Big Bore model has standard fittings, such as a round headlight on the front, a teardrop-shaped fuel tank, a two-piece dual seat, side-mounted shocks, a dual exhaust system with a muffler on each side, and five-spoke lightweight aluminum wheels.

The bike was built on a tubular steel twin-spine frame with a 47 mm Showa telescopic fork and 120 mm wheel travel on the front and dual side-mounted adjustable Showa shock absorbers with 95 mm wheel travel on the rear.

The bike's braking power was handled by two 310 mm floating discs with four-piston Nissin calipers on the front and a 310 mm disc with a dual-piston Brembo caliper on the rear, offering excellent stopping power.

As for the power figures, the 2009 Triumph Thunderbird Big Bore had its soul brought to life by a 1,700cc four-stroke parallel-twin liquid-cooled engine that delivered 97 hp at 4,850 rpm and 156 Nm (115 lb-ft) torque at 2,750 rpm.
