The GoldenTyre GT280 Jacky Tsunami wasåÊdeveloped in cooperation with former Motocross World Champion Jacky Martens, which is also where the unique "Jacky Tsunami" name comes from. Years of testing and development in the sandåÊtracks of Europe with Martens (who won 2 consecutive FIM 500cc World Motocross Championships) are what make the GT280 the ultimate sand and mud terrain tyre.
