2010 Harley Street Bob vs 2010 Triumph Thunderbird Photo Gallery

Harley has kept the design of the 2010 Street Bob clean and simple with bobbed fenders showcasing the black, steel-laced spoke wheels and Michelin Scorcher tires.

Motorcycle USA pits the British-made, water-cooled Parallel Twin of the 2010 Triumph Thunderbird vs. the American-made, air-cooled V-Twin-powered 2010 Harley Street Bob in our cruiser comparo.

It's the Revolutionary War all over again as we pit American and British cruiser motorcycles in a head-to-head comparison.

The 1584cc TWin Cam 96 engine is surprisingly peppy and has no difficulty setting the 658-lb (curb weight) cruiser in motion.

The Thunderbird we tested sported a racy white stripe down the middle of its tank, and its torque-filled parallel twin echoed those race-bred sentiments.

The 2010 Street Bob sports Harley's new fuel tank medallion design.

It's the Revolutionary War Revisited in the battle between the British-made, liquid-cooled parallel twin and the air-cooled American-made V-Twin.

The dual 310mm discs with 4-pot Nissin calipers on the front end of the Triumph have great feel and a solid bite.

"The Triumph represents the type of cruiser I enjoy riding," said Motorcycle USA Editorial Director Ken Hutchison.

The Street Bob's tank-mounted console features an analog speedo, a clock, dual tripmeters and no tach.

The Thunderbird features a torque-filled Parallel Twin engine, a silky-smooth transmission and powerful brakes.

The 2010 Triumph Thunderbird

Harley has kept the design of the Street Bob clean and simple with bobbed fenders showcasing the black, laced-steel spoke wheels and Michelin Scorcher tires.

At the heart of the Street Bob is a vibe-filled, air-cooled, Twin Cam 96 engine.

The 2010 Harley-Davidson Street Bob has factory apes and a blacked-out treatment that could bring out the rebel in any rider.

We headed out to our favorite Oregon backroads to test the handling of the motorcycles in our cruiser comparo.

The Thunderbird hooks up impressively with just shy of peak power available as early as 2000 rpm.

The Thunderbird is all spit-and-polish, with classy looking machined engine heads and chrome primary and crankcase covers.

The machining on the heads of the Parallel Twin add to the Thunderbird's classy lines.

Instrumenation on the Thunderbird centers around the big, round dial of an analog speedo with a small tach located opposite it.

What's your favorite flavor, Parallel Twin or V-Twin power?

The Harley Street Bob is nimble for a big cruiser.

The T-Bird's bars are spread a generous 34.6 inches apart

The powerful 1597cc mill of the Thunderbird tested out at 91.01 lb-ft at 2700 rpm on our Dynojet 200i.

Nothing is finer than cruising along on your favorite backroad on a sun-drenched day.

Pop the clutch, Hutch! This is what happens when you ask a track guy who loves to ride moto as well to help out on a cruiser test.

With almost identical displacements, 6-speed gearboxes, EFI, belt drives and twin exposed rear shocks, the Triumph Thunderbird and Harley Street Bob match up favorably.

Dyno Chart for the 2010 Triumph Thunderbird and the 2010 Harley-Davidson Street Bob.

Let it fly, Hutch! Sometimes he takes testing a bike's suspension to extremes.

Dyno numbers can only tell you so much about a bike. The true test came when we were able to get out of town and ride.

The Thunderbird holds a big advantage on the dyno chart but also weighs in at almost 100 lbs more than the Street Bob.
