Sport-oriented Pirelli and street-oriented Metzeler
The Italian-born Pirelli and the German-originated Metzeler, which now specializes in motorcycles, are known for their overwhelming potential in circuit riding with tires that can be used on public roads. The two brands are now part of the same company, following the acquisition of Metzeler by Pirelli in 1986, but they continue to produce different products, each with its own philosophy.
A simple interpretation is that Pirelli values sporting performance and a passion for racing. The Metzeler is also a racing machine, but it also believes in multiple performance and security that works for touring. Both have diverse lineups. You'll be able to get the most out of your motorcycle.
