At the INTERMOT Cologne show, Triumph unveiled its new Thunderbird cruiser to take on the Big Twins in America. Powered by a 1599 DOHC Parallel Twin, the Thunderbird bridges the gap between Triumph's smaller displacement cruisers and the mammoth Rocket III.The new Twin gets its displacement via a big 103.8 x 94.3mm bore and stroke. Power claims on the new Thunderbird's spec sheet claims "in excess of" 80 hp and 100 lb-ft of torque. Driving that power to the rear wheel is a belt drive and six-speed transmission. The all-new powerplant is liquid-cooled with fuel injection.
The chassis includes cast aluminum five-spoke wheels mated to a tubular steel frame and swingarm. Showa suspension components are sourced, 47mm fork up front and chromed spring shocks out back (shocks are five-position preload adjustable.)
Dual 310mm front rotors are pinched by 4-piston Nissin calipers, with rear braking a single 310mm rotor teamed with a 2-piston Brembo caliper. ABS will be available as an option for potential customers.
A 5.5-gallon fuel tank also houses the instrument cluster, with speedo, tach and LCD display. The Thunderbird will also utilize self-cancelling turn signals.
Built to compete directly with the Twin Cam Harley-Davidson, the new Triumph Thunderbird will be an important piece of the American Triumph strategy.
"It's been obvious for many years to people that from the American Speedmaster, there's a big gap between those bikes and the Rocket III," said Simon Warburton, Triumph Head Product Manager. "We see the future of the Thunderbird being a big part of our range."
2010 Triumph Thunderbird
The American cruiser market will have a new option in the 1599cc Triumph Thunderbird.
The base model will feature numerous accessories for customization, including touring and two-up extras, as well as cosmetic upgrades. American Trumpet fans will have to wait, however, as the new Thunderbird is not slated for US shores until September of 2009, making it a 2010 model. Pricing for the US market is yet to be determined.
