TRASK Dyna Original (OG) Turbo

The OG Turbo System gives your Dyna a serious horsepower upgrade without losing the lean, stock look. Designed for riders who want to run hard without looking flashy, this bolt-on kit delivers smooth, reliable power and the kind of pull that makes every twist of the throttle count.

Built from proven components and backed by Trask’s track record for performance, the OG system combines stealth styling with turbocharged performance — all without tearing the bike apart. Just bolt it on and let it rip.

Keep it simple. Make it fast.
