NR90970 - Comet HD Brushless Speed Control

Comet HD Brushless Speed Control

In an intense two year development process, NOSRAM was again able to widen the horizon of brushless technology. NOSRAM is proud to return with a new benchmark setting speed control platform: the comet evo & comet HD brushless speedos will rock the market. Beginning from a blank sheet of paper, the aim of NOSRAM’s r&d engineers was to replace the three popular pearl evo version 2 by just the two comet speed controls.

The NOSRAM comet speed controls are ready for modified and stock racing. They feature multiple options for your individual perfect setup. Being the successor of a World Championship winning speedo is a strong commitment. How can the comet be even better?

What does it make stand out from the crowd? Tremendous power output over the whole rpm range, easy setup, optimized cooling and peerless software are only some of the comet’s highlights. In addition, the innovative case is tailored from machined aluminum resulting in a better heat dissipation. NOSRAM has never released a more powerful speedo. Everything is ready for a great success story. Racers out there, go out on the track, race and win – with the new NOSRAM comet evo & comet HD brushless speed controls!
