Honda's second-quarter profit more than doubled, brushing off damage from a strengthening yen as car and motorcycle sales grew in the U.S. and Japan.

Honda Motor Co. reported Friday a net July-September profit of ¥135.93 billion, compared with ¥54 billion earned the same period in 2009.

Tokyo-based Honda also raised its profit forecast for the full year through March 2011 to ¥500 billion from its earlier projection of ¥455 billion. That would mark an 86 percent jump from the previous year.

The results show the resilience of the automaker amid a battering from a plunging dollar, which erodes the value of overseas earnings of this nation's exporters.

Quarterly sales rose 9.5 percent to ¥2.252 trillion on solid global demand for Honda vehicles.

Honda sold 898,000 vehicles during the quarter globally, up 7.2 percent from the previous year.

Japan vehicle sales surged 12 percent, helped by tax breaks and incentives for fuel-efficient green cars, while U.S. sales edged up 6 percent.

The only major region to see a sales decline was Europe, according to the manufacturer of the Insight hybrid, Accord sedan and Asimo humanoid robot.
