The EXO R2000 is Scorpion's flagship performance race helmet. Built with exclusive TCT composite shell construction, the lightweight EXO-2000 was developed by Scorpion engineers with input from MotoGP riders and tested on the track as well as in the lab. Scorpion's exclusive Ellip-Tec The Ellip-Tec Ratchet System uses an elliptical motion, creating 7.6mm of travel pulling the shield securely against the eyeport, thus ensuring a proper seal. Ellip-Tec is a 100% tool-less changing system. ratchet technology ensures a tight seal around the shield while the advanced aero-tuned ventilation system produces generous airflow and circulation throughout the helmet.
