Shoei RF-1100 Diabolic Feud Helmet

SHOEI is proud to introduce the all-new RF-1100 Helmet, which is built on the strongest pedigree in the motorcycle helmet business. The Shoei RF-1000 Helmet has enjoyed great success since its 2003 inception, but that didn’t stop SHOEI’s world-class development team from throwing out the molds to build a brand-new helmet from scratch. Combining  dealer and customer requests with advanced technology, modern testing practices, and fifty years of helmet-building experience, SHOEI delivers the finest sport-touring helmet that money can buy. The all-new, groundbreaking Shoei RF-1100 - where aggressive styling meets SHOEI’s unrivaled attention to detail, and the evolution of perfection is once again met.

AIM+ Shell Construction:

  • Aerodynamic properties are maximized through extensive wind tunnel and professional riders’ feedback
  • High performance fiber materials are combined with extremely elastic organic fibers to create shell structure that is ultra lightweight, rigid and resilient
  • 5 Shell Sizes and six EPS liner configurations present increased fit options that comfortably fit most head sizes
  • A third generation Tail Fin, integrated into the bottom rear beading in combination with the Shell-Integrated Spoiler, allows smooth airflow that reduces drag and lift

CW-1 Face Shield

  • The CW-1, three-dimensionally curved shield is both wider and taller than the CX-1V it replaces 

Q.R.S.A. (Quick Release Self-Adjusting) Base Plate System

  • Q.R.S.A. base plate allows for tool-less face shield removal and installation. 
  • Every time the shield is lowered, the spring-loaded base plate (U.S. patent pending 11/799935) pulls the shield back to contact the window beading evenly, ensuring a wind and waterproof seal between shield and helmet

Variable Ventilation System

  • Upper Air Intake Vent is positioned to maximize air volume into the helmet interior
  • Top outlet vent is separate from the Shell-
  • Integrated Spoiler, allowing it to be positioned for optimum flow-through ventilation
  • Four rear outlet vents allow for adjustment of airflow based on riding position
  • Enlarged lower air intake/defroster vent reduces shield fogging and increases ventilation
  • The rear/neck outlets allow for effective air exhaust
  • Breath guard and chin curtain included 

Interior System

  • The entire interior lining (cheek pads, crown liner and chin strap covers) is easily removed to allow cleaning
  • Each component of the inner liner is ergonomically designed to offer the ultimate in safety, fit and comfort
  • Eyeglass compatible

Tech Specs

  • 5 shell sizes
  • Weight: 3.54 Pounds / 1604grams (based on size medium / solid color)
  • DOT and Snell M2010 approved

Shoei RF-1100 Diabolic Feud Helmet 4.4 5 7 7
Better than Bell?? I honestly thought that the helmet would be a bit better than my Bell Arrow helmet, but for the price, I just can't justify getting the same product again. Not sure if I will ever get another Shoei for 300-400 dollars, when a 150 dollar Bell will be just as good. May 4, 2013
Awesome Decided on this helmet because 1) had the best fit for my head. It's best suited for the long oval instead of the round heads 2) the graphics are cool, hard to the notice in the pictures but there's a section of pattern going from the front to back that is pearl paint, changes from purple to green color. My only grip is that sometimes it's little noisy on the highways but you can play w/ the vents to quiet it down, otherwise it's spot on. Good fit and nice airflow. April 22, 2013
Love it!! Great fit, thanks to Revzilla customer support helping me out with sizing! Picture doesn't do it justice, has a lot of details and iridescent work that you can only see at certain angles. Extremely easy to remove visor, and i love the click to vent feature on the helmet! Overall Excellent buy!! April 22, 2013
Riding for over 30 years, best helmet I have ever owned. Comfort and visability are unmatched by any other full faced helmet I have owned. Head size fell just between a medium /large, purchased a medium. Felt snug at first, now I don't even realize I have it on. Shield system is very nice, seals well, changing shields is simple. May seem high priced at first glance, but you get what you pay for. April 15, 2013
Won't go wrong I have had a couple of Helmets already from an Arai and ICON. This is of the same standard of an ARAI, but yo cannot simply compare an ICON to a shoei. It's like saying driving a toyota vs a lexus. The shoei has more quality to it's work, quieter that an ICON (geese not sure if you can use quiet and ICON in the same sentence). Compared to an Arai, I believe you'll be spending less with a shoei to get the same quality as in a Arai. Design and looks, I'll go for a Shoei over an Arai, just my two cents. March 25, 2013
Great Style What good is a helmet if you dont wear it? With great styling and comfort you'll definatly wear this one. Read the specs for more info. Go try it on if you're still not convinced. Its a Shoei. You get what you pay for! February 4, 2013
Its a shoei. Last helmet was a RF-1100 and decided to replace it with the exact same helmet. Only thing I wish was different would be perhaps some better graphics and emergency cheek pad releases otherwise I have no complaints about the helmet. January 22, 2013
