The Dunlop K990 is a vintage motocross tire Dunlop reintroduced to match the off-road racing tread pattern used in the early 1990s. It is built for small-bore vintage motocross bikes competing in the 100cc and 125cc classes, giving restorers and vintage racers a period-correct, DOT-legal-era-style tire with modern manufacturing. It is offered in a 70/100-21 front size; Dunlop's companion 90/100-18 rear size is not part of this catalog's size list.
