Amazing
09 Jul 2026 by Lykourgos
I'm really happy with this helmet. The helmet looks even better in person than it does in the photos. The gloss carbon finish is beautiful and the overall quality feels excellent.
Comfort wise is perfect. It was a little tight (Medium size) when I first tried it on, but after gently massaging the cheek pads and wearing it for a few rides, it fitted perfectly. Now it feels very secure without being uncomfortable.
I was also surprised by how quiet it is for a sporty helmet. It's obviously not a touring helmet, but wind noise is very reasonable, especially at motorway speeds.
Overall, I'm extremely pleased with my purchase and would definitely recommend it to anyone looking for a lightweight, comfortable and premium-looking helmet. price was excellent too
As always, Sportsbikeshop provided outstanding service. Fast delivery, great communication and an excellent buying experience from start to finish.

Flawless 
02 Jul 2026 by Chris
Fit is fantastic, medium oval shape. Removable foam section from cheek pads is a godsend for glasses wearers like myself. No more fighting and bending glasses legs. Finish is top tier. Fairing being removable suits if you wear a backpack or if you simply don’t have an aero hump for it to sync up with.

Brilliant finish - fits perfectly

The finish on this carbon helmet is unmatched. And it’s so comfortable! After about an hour trying on different helmets in the store in Leeds this was the Cinderella shoe for me.

Great quality, great comfort, even better looks.

Was never really drawn to Nolan but after a while the good looks made me buy one and I can without a doubt say it’s been the best helmet I’ve owned. Super comfortable and light weight whilst still feeling solid and high quality. Pretty much no wind drag at higher speed and stays surprisingly quiet for a carbon race helmet. 10/10 would recommend.

Brilliant helmet
15 Feb 2026 by Karl
I heard a lot of praise about this helmet and I definitely agree. It’s one of the best looking options on the market especially for the price, it’s lightweight, incredibly comfortable and the noise isn’t too bad either. It competes with the supertech R10 and even the Pista - whist being half the price!

Most comfortable helmet so far
22 Jan 2026 by Phil
I must have a funny shaped head! Shoei, Arai, Shark, give it 20 mins on the road and all 3 of those, which I thought were comfortable in-store would either leave me with a severe headache or a sore head with multiple indentations.
I’ve gone with a XXXL Nolan, normally an XL. I still get a small line on my forehead after an hours wear, the mark I get is from the stitching line just above the forehead section inside. But I can live with it over all my previous helmet issues.
I went with the gloss carbon. Which looks better than the matte version. The X-804 has a broad range of prices from £400-£700, but why pay top tier for the same helmet just to have a lame design on it when you can get the naked carbon effect with a black “Nolan” logo on the front. I don’t like the look of helmets with their branding embossed all over it in contrasting colours. This helmet has the stealth effect, which looks great, even more so with the provided black/ dark visor.
I find the pinlock fog system brilliant as well, ventilation is good when on the move. And I find it less muggy inside with the visor down than I have with other brands.

The helmet is quite light, which was really important too me. Good ventilation and super comfy to wear. Recently done around 5-6 hours of riding in one day and have no complaints. Bought it at really good price, so overall very happy with the purchase.

In the long tradition of Italian motorsport excellence, the X-804 Ultra Carbon is built to perform at high speed. The cutting-edge carbon masterpiece is engineered for passionate riders seeking unmatched strength, unparalleled safety, ultimate comfort, feather-light, and aerodynamic finesse.
Its sleek, aggressive design commands attention on any track or road.
SVLS - Safety Visor Lock System
This exclusive system prevents the visor of the helmet from opening accidentally.
The Safety Visor Lock can also help to prevent the visor from opening during a crash, which could protect the rider's face from injury.
In addition to preventing accidental openings, the system can also be used to create a 'minimum visor opening' for demisting. This is a small opening that allows air to circulate inside the helmet, preventing the visor from fogging up.
RAS - Racetrack Aerodynamic Spoiler
Developed in collaboration with official Nolan riders, the RAS is an aerodynamic spoiler designed through Computational Fluid Dynamics (CFD) studies and wind tunnel trials.
The shape of the upper part reduces aerodynamic resistance and enhances stability at high speeds, especially in a head-down positions when aligned with the rider's suit hump.
Additionally, the lateral parts improve helmet stability in the airflow from the headlight fairing. The RAS is removable to accommodate various riding conditions and situations.
RAF - Racing Air Flow
The exclusive Racing Air Flow system optimises ventilation for racing conditions, keep you cool and focused even at high speeds.
LAF - Liner Adjustable Fitting
The Liner Adjustable Fitting allows the rider to perfectly adjust the internal padding depending on the head shape, maximising the internal comfort whilst wearing the X-804.
NERS - Nolan Emergency Release System
The NERS allows emergency teams to remove the cheek pads from the helmet while it is still being worn by the motorcyclist.
By simply pulling the red tapes attached to the front of the pads, the NERS ensures quick and efficient access in emergency situations.
Featuring an advanced version of the Nolan Emergency Release System (NERS), this helmet ensures swift and secure removal in critical situations, prioritizing your safety above all else; at same time, the traditional assembly system simplifies the assembly and disassembly process without using hooks.
Carbon Fit Racing Experience
Nolan's internal comfort padding is constructed with active carbon filaments, offering thermoregulatory, antistatic, and dissipative benefits.
The liner, featuring an innovative net structure, promotes efficient airflow in the upper part of the head, ensuring optimal cooling and dryness.
EA - Eyewear Adaptive
This system is designed to provide comfort for glasses wearers. It creates a space in the cheek pads for eyeglass temples, making it quick and easy to put on and take off your glasses.
The cheek pads are reversible, so you can return them to their original configuration if you no longer need the space for your glasses.
The cheek pads also have expanded foam inner padding that can be removed from the fabric covering the easy washing.
