Ready to explore both pavement and dirt? The Continental TKC 80 is a legendary dual-sport tire built for adventure riding. This is the front tire in size 90/90-21 (part #02405670000). Its aggressive, blocky tread pattern is designed to dig in off-road, giving you excellent braking and traction on everything from loose gravel to hard-packed trails. The blocks are spaced to help self-clean from mud. But it's also designed with a specific compound and block shape to work well on the street, offering good stability and predictable handling when you're riding to the trails. Continental rates it as 60% off-road / 40% on-road. So if you ride a dual-sport or adventure bike and want a tire that can confidently handle a mix of terrain, the TKC 80 is a top-tier, proven choice. (Note: Tires are sold individually.)
