The MT 21 Rallycross is Pirelli's enduro/dual-sport tire built for riders who leave paved roads, with a bias-ply, tube-type construction. Pirelli designed the tread pattern for dirt and gravel roads, cross-country racing, and desert touring, backed by a stiffer carcass for stability and cornering precision off-road. It uses a dedicated off-road compound intended to resist block tearing for longer off-road service life. It is sold in a wide range of 17, 18, and 21in front/rear sizes for adventure and enduro motorcycles.
