The Yamaha XV1900A, known in the US as the Star Roadliner, was a cruiser motorcycle that debuted in 2006 and continued production until 2017. The bike was sold in the American market through Yamaha's Star Motorcycles division and was the largest motorcycle while in production.
The bike was developed to take on the large displacement part of the cruiser market, already occupied by the 1,600cc Wild Star model. So Yamaha had to redesign the 1,600cc engine for on-coming exhaust emission regulations and made some styling modifications, resulting in the introduction of the big 1,900cc Roadliner.
In 2006, the Japanese motorcycle manufacturer launched the Yamaha Roadliner, a cruiser motorcycle that combined the classic neo-retro looks of the big-bore Star motorcycles with modern technology.
For appearance, the bike had standard features, such as a large round headlight integrated into a large chromed housing, a wide, pulled-back handlebar, a teardrop-styled tank, a two-piece dual seat, a two-into-one chromed exhaust system, and 12-spoke lightweight aluminum wheels.
Between the bike's wheels and underneath its fuel tank, it was installed a stylish 1,853cc four-stroke V-twin air-cooled engine fed by an electronically controlled fuel injection system boasting 99 hp with a peak force at 4,250 rpm and 167 Nm (123 lb-ft) torque at 2,250 rpm.
In the braking department, the 2006 Yamaha Roadliner had installed two 298 mm discs with four-piston calipers on the front wheel and a 320 mm disc with a four-piston caliper on the rear wheel, providing excellent stopping power.
