Dynatek DRL-400-HD-EFI Two Stage Rev Limiter is a high-performance ignition accessory designed specifically for Harley-Davidson EFI models, delivering precise RPM control for drag racing and performance applications. Featuring dual independent rev limiters, this unit allows riders to maintain consistent launch RPM while also protecting the engine from over-rev conditions at high speed.
Designed for plug-and-play installation, the DRL-400-HD-EFI connects directly to the factory ignition coil using OEM-style connectors, making it a simple yet powerful upgrade for performance builds. By holding engine RPM steady during launches, it improves consistency, reduces rider error, and maximises acceleration off the line.
