HJC RPHA-10 Lorenzo Replica Helmet

The HJC RPHA-10 Lorenzo Replica Helmet has the Monster Energy™ logo on the sides and the red X on the top. This is a replica of the helmet that is worn by Jorge Lorenzo in the Moto GP series which is the premiere motorcycle racing class. The HJC RPHA-10 is one of the higher end offerings from HJC. This motorcycle helmet has Advanced P.I.M. and is one of the most well ventilated helmets on the market. This helmet meets or exceeds both SNELL and D.O.T. standards and comes with many different features like fully removable crown and cheek pads for washing as well as the Rapid Fire II™ quick replacement shield system to allow for quick changes from a tinted shield to a clear one when riding in transition from day to night.

All RPHA helmets feature HJC's Premium Integrated Matrix (PIM) construction, which incorporates three different materials—carbon fiber, aramid fiber and fiberglass—to create a unique woven blend that is both remarkably strong and lighter compared to conventional helmet materials. Precisely sized segments of PIM material are carefully hand-laid into special pre-molds for shaping, and the controlled placement of these layers virtually eliminates unneeded overlap of fibers for a more precise forming process. All of which results in a shell weight that is significantly lighter than competing designs for greater rider comfort.

To create these modern, complex shell designs, HJC employed CAD design and rapid-prototyping technology, along with extensive testing of multiple prototypes within HJC's state-of-the-art wind tunnel. Net result: carefully controlled aerodynamic airflow around the helmet for a smooth and quiet riding experience along with superior, well-controlled flow-though ventilation for additional rider comfort.

Because small details count when you're out riding all day long, these helmets incorporate features such as plush, luxurious interiors with self-cooling properties and an antibacterial treatment. Also, the interior pads are removable, washable and replaceable. In addition, since fine aesthetics elevate the pride of ownership, a whole new process for creating high-quality helmet graphics was created for use with these helmets. The RPHA series also feature HJC's substantial five-year warranty, and much more. With the new RPHA series of advanced-concept helmets, HJC has truly reinvented the parameters of helmet performance. But perhaps best of all, because the creation of these helmets benefits from the very latest and most efficient manufacturing processes, the HJC RPHA series brings features and technology to consumers at a price point that offers significant value. With HJC, being number one in the world among all helmet manufacturers means there's never time to stop developing new ways to do it better—better by design. The center-locking shield system on the HJC RPHA 10 and HJC RPHA Max produces a secure seal, and the shield itself is Pinlock®-ready and mounts via HJC's RapidFire™II Shield Replacement System. This simple and secure shield-ratchet system features a spring-loaded feature that firmly retains the shield in place during use. In addition, it also provides ultra-quick, tool-less shield removal and installation for efficient operation.

Inside, the HJC RPHA series helmets incorporate ultra-plush, premium interiors that are fully removable, washable and moisture-wicking, with a special antibacterial ginkgo extract that helps fight odor buildup in the lining. The HJC RPHA 10 features the vaunted SilverCool Plus™ interior, while the HJC RPHA Max and HJC RPHA X incorporate the newly created Cool4Ever™ interior with enhanced wicking properties that was developed specifically for off-road applications. All three of the HJC RPHA series helmets also feature variable air intake vents that are easily adjusted to suit riding conditions. HJC's Advanced Channeling Ventilation System gives full front-to-back airflow to flush out heat and humidity. Top it all off with an industry-leading five-year warranty on materials and workmanship, and it becomes patently obvious that the new HJC RPHA 10, HJC RPHA Max and HJC RPHA X have literally advanced the state of the art in helmet design.

“… With its quietness, luxury interior and deluxe shield changing the RPS-10 has the feel and fit of a top-line hat…” -Rider Magazine

“… We were very impressed with the HJC RPS-10. The company has often been perceived as one of the second-tier helmet manufacturers as far as performance and quality- but we think that’s going to change with the new RPS-10…” - SportRider Magazine

“… Aviation-style vents flow air across your temples for efficient cooling. Hundreds of hours in the wind tunnel ensure the helmet cuts through the air without turbulence…” - MotorCyclist Magazine

“… Improved aerodynamics, a snugger seal along the bottom of the cheeks and a thick chin curtain seal out wind and make the RPS-10 noticeably quieter than the FS-15- fully 4 decibels quieter, according to HJC. At speed the helmet exhibits excellent stability and cuts through the air without buffeting, even when you turn your head to check our six at triple-digit speeds. Large vents on the helmet’s brow flow big air and are easily operated with gloves on; slide your hand rearward to open the vents and forward to close them…” - MotorCyclist Magazine

“… The quality of this helmet with regards to the graphics and clear coat is phenomenal. If you’ve had one of HJC’s models in the lower price range and perhaps haven’t been totally satisfied with it then this is an opportunity for you to check out the RPS-10. The fit-n-finish is superb and easily sets the RPS-10 as the leader in HJC’s product lineup. Competing against the likes of Arai, Shoei and other premium helmet manufacturers is a difficult task but one that HJC has taken head on and is winning…”
