Sea-Doo’s got the big daddy horsepower title. Yamaha’s new 1.9L certainly has the displacement. So what about Kawasaki? With the Ultra recently toppled from its “king of the hill” horsepower title, and touting the smallest displacement of all of the Big 3’s mightiest runabouts, it’s time JetSki gets a little love.
RIVA Racing just dropped a heck of a bombshell with the announcement of its new “K3” Supercharger Pulley Kit. The 101mm diameter main pulley spools up an addition 3psi over the OEM supercharger pulley, delivering more acceleration and a higher top speed (when paired with RIVA’s Stage 3 tune for correct calibration).
Made from high strength billet aluminum and coated with a military spec material for improved belt wear and corrosion resistance, the K3 Supercharger Pulley Kit also includes a stainless steel idler pulley with precision stainless bearing and special idler pulley installation tool, providing you all you need to make the swap.
Made entirely in the USA, RIVA Racing’s new K3 Supercharger Pulley Kit is designed for all 2014-and-newer Kawasaki Ultra 310 models. Priced at $492.96, and designed for strength, precision and corrosion-resistance in mind, you can ramp up the boost and keep your Kawi pinned longer and harder than ever before.
