After a long-anticipated wait – and we are very bad at waiting – Metzeler has finally unveiled their Karoo 4 Knobbly Tyre to the Moto masses. 

Metzeler’s aim in creating this unit was to marry quality off-road traction with the benefits of on-road stability. In a world where adventure motorcycles are becoming more and more synonymous with comfort and accessibility, it was only a matter of time before we got some updated offerings set to fill the ‘do-it-all’ shelf for Maxi Enduro riders – so let’s get into it.

Updates to this unit include a new tread patent design, Metzeler’s Multiple Radius Contour (MRC) technology that Metzeler’s press release states “improves line holding despite the ‘knobs’,” carbon black-based compounds and footprint area optimisation for cut and tearing resistance, as well as an apparent improvement in performance when dealing with current riding modes – wet weather and any extra emergency brake situation included.

Performance is even improved for ultra-soft surfaces, such as sand and mud.
