EVS R4K

MOTOCROSS NECK COLLAR

EVS R4K

KOROYD INTEGRATION

The EVS R4K is made with 5 Koroyd inserts. The R4K is the lightest neck collar on the market without compromising on performance.

SUPERIOR ENERGY ABSORPTION

The Koroyd structure has extremely efficient and consistent energy absorption properties. The cores decelerate the energy from an impact to reduce final trauma levels.

LIGHTWEIGHT

Thanks to Koroyd the R4K is 20% lighter than other race collars on the market

COMPRESSION

Up to 8 times higher compressive strength than competing products.

LIMITING SPINE COMPRESSION

A higher compressive strength helps to maintain the distance between the helmet and the riders shoulders. Limting the risk of spine compression.

SUPERIOR ENERGY ABSORPTION

Koroyd excels at reducing Peak G and HIC figures – limiting the risk of skull fractures and traumatic brain injury. When impacted the cores crush in a controlled and homogenous manner, decelerating the energy from the impact and reducing the final trauma levels.

OUTLINE

  • Koroyd engineered core for superior impact absorption.
  • Reinforced nylon upper shell.
  • Lightweight, aerodynamic chassis design.
  • Rapid lock closure system for easy front entry.
  • Integrated X-Strap cleats.
  • Polyurethane foam base.

DESCRIPTION

The R4K is a completely new race collar for 2016. It features a revolutionary Koroyd core with superior impact absorption and a reinforced nylon upper shell. The chassis has been completely redesigned to be lighter and more aerodynamic. In an impact, the head is pushed down on the race collar. The R4K effectively fills the gap between your helmet and shoulder with Koroyd, which absorbs impact energy better than standard race collar materials.
