The Shark RSI Helmet was the bestselling lid in Shark's composite fiber helmet range in recent years. So they decided to go ahead and improve it even further and call it the Shark RSI Pro Helmet. The Shark RSI Pro Helmet now features a brand new rear spoiler to improve stability at higher speeds, a new magnetic chin strap closure system, and is now fully capable of integrating with eyeglasses. The Shark RSI-Pro Helmet also improves upon the guts of the RSI, with a new limited edition interior scheme. Maintaining the aggressive sportbike nature of the RSI, the Shark RSI Pro Helmet is subtly tweaked to greatly improve overall functionality.
