The Dunlop Sportmax GPR-300 is a radial sport tire built to give a balance of grip and wear at an affordable price across 250-600cc-plus sportbikes. Jointless Band (JLB) rear construction uses a continuously wound belt for a consistent tire contact patch and smooth performance. The tire is tuned for quick turn-in and stable cornering response for street-going sport riding, with a wet/dry grip balance aimed at longer wear life. It is offered in three front sizes and six rear sizes, covering small-displacement sportbikes up through literbike-class rears.
