In 1905, Indian built its first V-twin factory racer and in following years made a strong showing in racing and record-breaking. In 1907, the company introduced the first street version V-twin and a roadster styled after the factory racer. The roadster can be distinguished from the racers by the presence of twist grip linkages. One of the firm's most famous riders was Erwin "Cannonball" Baker, who set many long-distance records. In 1914, he rode an Indian across America, from San Diego to New York, in a record 11 days, 12 hours and ten minutes. Baker's mount in subsequent years was the Powerplus, a side-valve V-twin, which was introduced in 1916. Its 61ci (1000 cc), 42 degree V-twin engine was more powerful and quieter than previous designs, giving a top speed of 60 mph (96 km/h). The Powerplus was highly successful, both as a roadster and as the basis for racing bikes. It remained in production with few changes until 1924.
