Metzeler Karoo Extreme - 90/100 21 (57R)

Whilst the production of Metzeler tyres began in 1892, the company goes back even further. Founded by Robert Friedrich Metzeler in 1863, the company began with the manufacture of weatherproof clothing and sports equipment, amongst other items. Since 1979, however, Metzeler have focused almost entirely on motorcycle tyres and now produce one of the most comprehensive ranges of bike tyres on the market. Although acquired by Pirelli in 1986, Metzeler remain both independent and highly focused in their mission to meet the needs and expectations of todays motorcyclist. To help achieve this end, they're proud to say that the majority of Metzeler staff are bikers, which can only be a good thing!
