Shoei RF-1100 Merciless Helmet

The Shoei RF-1100 Merciless Helmet is one of the more popular graphics in the Shoei RF-1100 line. The helmet has a matte finish with a skull and cross-bones theme over sweeping wings.  The new RF-1100 helmets build on the success of their predecessor  the RF-1000. Combining dealer and customer requests with advanced technology and modern testing practices, Shoei's world-class development team threw out the molds to build a brand-new helmet from scratch. SHOEI is pleased to deliver the finest sport-touring helmet that money can buy. 

Tech Specs

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

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 pulls the shield back to contact the window beading evenly, ensuring a wind and waterproof seal between shield and helmet

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

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
  • Rear/neck outlets allow for effective air exhaust
  • Breath guard and chin curtain included 

Interior System

  • 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

RevZilla Store asked: Why did you choose this?
robert h: like the company they make a quality product and really liked the graphic Feb 12, 2014
Brion W: Snell rating, great artwork, trusted name. Feb 10, 2014
Hervey W: My old Arai was done, my son is really happy with his RF1100 so when this went on closeout I jumped in. Very happy with it. Jan 13, 2014
P R: A helmet with these kind of reviews and it's on clearance (closeout or whatever) means "last chance" to own it. Then almost 200 off MSRP. Yup, had to get it. Designs are cool, LOVE the wings! Would look awesome even without the skulls but they should keep others on edge and hopefully away from me lol. (scary biker with skulls lol) I got the white, color should match my white bike nicely. I will leave a review once I use for couple months. (wish it had a visor) Dec 25, 2013
Leonardo A: For Color and design Nov 29, 2013
Josh B: Great features with this helmet, have a buddy with a RF-1000 and he sold me on shoei. Aug 13, 2013
A shopper asked: I'm getting a GPS for my bike and want to have a bluetooth microphone and speakers in the helmet. Are any of the systems out there particularly well suited for going in the RF-1100? Mar 26, 2013
Answer this · Send to friends Good question? Yes (0) No (0)
RevZilla: The RF-1100 has speaker cut outs and pretty good room in the chin as well which allows for any type of microphone. A few of the staff members here have an RF-1100 and mounting any device is easy to do and takes about 10 minutes. The ear cutouts are big enough to fit any of the speakers from the Bluetooth systems that we sell. We would recommend buying the device that has the features and price point that you want, as mounting it to the helmet wouldn't be an issue. Mar 26, 2013
