DescriptionThe whole story▼
Air that the X.R3R takes in at the front has to leave somewhere. Nexx gives the helmet four exhausts, and the two pieces in this set are the outer rear vent parts on the left and right side of the shell. They come as a pair under one part number.
Where they sit
Nexx's own close-up of the X.R3R shows two dark, pointed vent pieces at the back of the shell, either side of the raised centre section that leads to the spoiler. The parts in this set have the same angular outline and are mirrored for left and right. Nexx explains that air is guided over the top and sides to the rear, where it feeds the spoiler concept, so these outlets are part of the helmet's airflow, not decoration.
What can go wrong
Rear vents are exposed. A helmet that falls off a mirror or a petrol tank often lands on its back, and the thin plastic tips break off. Sliders on helmets with adjustable vents can also wear loose. Even a small missing piece changes how air leaves the helmet and can add noise at speed, and it spoils the look of an otherwise intact shell.
What is in the set
The photo shows two black pieces with a fine textured surface, one for each side. Screws or clips are not shown, and Nexx publishes no list of contents, so expect the two vent parts only. Whether these outlets can be opened and closed is not stated by Nexx for this part.
Replacing them
Because Nexx provides no fitting guide for this part, we suggest looking at how the old pieces are held before you remove anything. If they are glued or riveted to the shell rather than clipped, have a dealer workshop do the job so the shell surface stays undamaged.
Fitment
For the Nexx X.R3R. The Speedcore has its own X-Matrix 2 shell and Nexx lists it with five intakes and four exhausts; whether its rear vents are identical to the carbon helmet is not confirmed, so check with us first.
