To ensure the best fit, please carefully review our sizing guide before ordering. Do not assume your usual size based on other brands, as helmet sizing varies significantly between manufacturers. Use a tailor’s tape to measure your head circumference and refer to our size chart to determine the correct fit. Ensuring the right size before ordering will help you avoid delays in using your helmet.
Return Policy
Once tags have been removed or the helmet has been worn on a motorcycle, it cannot be returned. We strongly recommend keeping all tags attached and trying on the helmet indoors before use. If needed, wear it while sitting on your motorcycle to ensure comfort and a proper fit.
We display live inventory for in-stock items, which ship within 1–2 business days. Due to the variety of sizing, color options, and models this brand offers, we will drop ship from our supplier if the item is not stocked in our warehouse.
These products are seasonal and can sell out quickly, so availability may be limited.
John McGuinness Special Edition KX-1 Race GP with Signed Holographic Trading Card. Limited Quantity.
HELMET COMES WITH CLEAR VISOR - TINTED VISOR NOT INCLUDED, HELMET DESIGNS CAN CHANGE WITHOUT NOTICE

Designed and developed in Italy with the most advanced digital tools, the KX-1 Race GP motorcycle helmet has undergone rigorous testing by MotoGP, WorldSBK, Isle of Man TT, and Moto America racers to ensure it can perform at the pinnacle of the sport. It boasts industry-leading aerodynamics for reduced drag and peak race performance thanks to over three years of wind tunnel and track testing to optimize aerodynamics in various riding positions and lean angles. The KX-1 boasts enhanced peripheral field of view (92 deg and 210 deg) for unobstructed vision, and meets the highest FIM Standard. The interior of the KX-1 features a liner that has been expertly crafted with premium materials that lead in form and function.
The KX-1 Race GP motorcycle helmet is used in MotoGP™ and WorldSBK™ and continues to be adopted by world-class racers everywhere.
SHELL
The shell is made of TRICOMPOSITE fiber, a new composite that provides a lighter shell but at the same time harder and more protective.
The new composite is a mixture of carbon with different weight/breaking loads linked up with aramid resins that ensure a light shell but much more resistant to impacts.
The KX-1 Race GP is produced in three different shells: S,M and XL.
SIZING
Measure around the widest part of your head for proper sizing
Extra Small: 53-54 CM
Small: 55-56 CM
Medium: 57-58 CM
Large: 59-60 CM
Extra Large: 61-62 CM
Extra Extra Large: 63 CM
PROTECTIVE POLYSTYRENE
Internal polystyrene liner (EPS) in three sizes (S, M and XL) to obtain a better ergonomics and a variable density. This characteristic allows a gradual and progressive absorption of the power produced by the impact.
Even if the majority of the energy created by the impact is absorbed by the external shell, thanks to its deformation, the role of polystyrene is crucial for the absorption of the residual energy.
Varying densities of the polystyrene allows optimization of the mechanical performance of the shell-polystyrene, ensuring the maximum level of absorption in all areas of the helmet.
VISOR
The visor is PC injected, anti-scratch, with variable thickness. Easy to remove. The release lever is made of a particular metal alloy that gives greater structure and positive closure to the assembly. The visor is also equipped with a “Racing Lock System” in metal alloy. The mechanism reduces the possibility of detachment in case of crash. KX-1 Race GP visors are prepared for racing tear off.
***HELMET COMES WITH CLEAR VISOR - TINTED VISOR NOT INCLUDED***
PINLOCK
KX-1 Race GP is compatible with PINLOCK® MAX VISION 120, the highest performing antifog system in the market.
VENTILATION
It is during the hottest Grand Prix that the most is asked from the rider, requiring concentration and endurance. Being able to count on efficient ventilation makes all the difference.
KX-1 Race GP includes seven air intake ducts which work in conjunction with a neatly integrated channel system, guaranteeing excellent airflow inside the helmet.
The hot air extraction is a marvel of aerodynamics: two submerged air extractors, working together with the rear spoiler create a Venturi effect over the exhaust ports, draw out the hot air.
INNERS
The cheek pads and the internal comfort liner can be removed, washed and replaced.
They are made of premium fabric with specific fibers that offers the following features:
Cheek pads are customizable and easily removable in case of emergency thanks to the quick release system.
KX-1 Race GP is prepared for the camel-bag hydration system (not included).
RETENTION SYSTEM
The chin strap is uses a double D-ring retention system enabling an easy release and secure system.

The higher pressure cap stopped my overflow from becoming pressurized and blowing out. I did a combustion gas test on the cooing system and it passed all 3 times, so it made since the factory cap was to low of a rating for serve duty.
The internet provides many options. Not all are good. HHR provides top notch customer service and the best parts available.
quick shipper
awesome customer service
I ordered Avio fiber glass fairing and all necessary brackets for 2023 Yamaha r1. HHR answered all my questions by email and later by phone. The staff I communicated with were knowledgeable, straightforward, helpful, and non-judgmental. I've had been using the products for more than a year, and I have no complaints and am quite happy with it. I've heard it's easy to installl, too, but I had someone else do it, so I can't say if that's true. The bodywork has cutouts for the tail light and headlights. Works great.
Best store to buy
Always willing to help and with patience
One fine piece of carbon fiber. Light as a feather. Bike rides like a whole different monster
