TOKYO -- Japan's Honda Motor Corp. and Yamaha Motor Co. will cut domestic production of medium- and large-sized motorcycles by roughly 10 percent and 20 percent respectively, the Nikkei business daily said on Saturday.

The cuts, which will take place in the current business year, are due to slowing demand in the United States and Europe, which account for roughly 60 percent of the motorcycles Japan exports.

Hit particularly hard is demand for motorcycles of 250cc and over.

According to the Nikkei, Honda will cut its domestic production by roughly 10 percent to 400,000 motorcycles, while Yamaha will trim production by some 20 percent to 350,000-360,000.

Officials at both companies were not available for comment.
