Stilo Drink System Helmet Kit for ST4 & ST5

Stilo drinks system helmet kit for ST4 & ST5 helmets. Included in this pack is a male coupling, tube and rubber bite valve. The coupling assembly is designed to allow the driver a quick evacuation so that in case of emergency, by just a slight tug, the coupling slips off releasing the driver. All pipes are fitted to the helmet internally.

For drink system bag (Hydration Bag, Tube & female quick coupling) please see YA0605.

Please note - Not suitable for ST4F-N, ST5F-N & ST5GT-N models which do not have drink system plug integration in shell.
