Why Choose K&N for your Hayabusa?

The Gen 2 Hayabusa is a masterclass in aerodynamic and mechanical power. Because it uses a sophisticated Ram-Air system to force air into the engine at speed, a restrictive paper filter can become a major bottleneck. The SU-1308 ensures that air velocity remains high, providing a sharper throttle response and helping the bike pull harder through the mid-range and top-end. Plus, the slightly deeper intake growl perfectly complements the Hayabusa’s aggressive presence.
