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

Note: Due to manufacturer restrictions, Shoei products can only be shipped to addresses within the United States

Shoei RF-1100 Merciless Helmet 4.8 5 600 600
Great product for the price you're paying for Very comfortable fit, air flow is good with it's 4 vents on the top. Good clear vision with a wide range. April 21, 2014
Excellent premium helmet from Shoei I hesitated in shelling out @$300+ for a helmet. Since i recently bought my new ride, I needed to chuck my old average helmet that saw 5 years of good use. Well once i put on the Shoei on, I realized why they charge so much. The fit is true to size and Ive never experience such a great fit. Riding with it on highway speeds in Texas, the noise level is so low and the airflow makes me confident to ride 40 miles to work in Houston Summer. If you are on the verge of making the jump to premium grade, i say buy this helmet. You will pat yourself on the back for doing so. April 21, 2014
Nice Helmet at a great deal I decided to upgrade to a better helmet than my current one and I'm glad I did. I got this Shoei RF-1100 Helmet in matte black at the closeout price which was a great deal. This helmet fits pretty true to size and like all other helmets will stretch out just a bit after you wear it a few times. The Shoei RF-1100 feels much lighter than my last helmet and fits much better. There is just a slight bit of wind noise but it's not too bad. All in all I am very happy with the Shoei RF-1100. This helmet is a great deal at the closeout price that Revzille has it for. April 17, 2014
Great helmet deal while they last I got this after they released the RF-1200 so I got a great deal, and saved money, but they are running out of stock as people are scooping them up. My RF-1100 seems to fit quite a bit tighter than my old RF-800 did, L'm going to try getting the narrower cheek pads to see if that helps. With the vents open, it stays dramatically cooler than my old RF-800, but there is a bit of a wind whistle anytime I turn my head even just a little off axis. April 14, 2014
very pleased Ok, full disclosure. I've been riding for forty years and have been wearing nothing but a 'brain bucket' for almost all of them. I know the protection offered with a full face but have been reluctant to convert. Well after just a few rides so far, I'm very pleased with this purchase. I thought that this helmet may end up sitting on the shelf for most of its life but now, that won't be the case. All of the positve attributes you hear about full face are true. Most of my preconcieved negatives are not. The only problem i can see is keeping my speed down now that I feel like I'm out on a 'track day' and not just out for a casual spin ! haha April 14, 2014
A Quality Helmet is Worth the Extra Money! I have been riding for many years and have used helmets of various styles and quality. This year I decided to spend a little extra and move up to a SHOEI. Compared to the many other models I have used, SHOEI surpasses all of them. The low weight and the aerodynamics make it the most comfortable helmet I have ever used, especially after wearing it a few days. You can feel the quality as you cinch the strap and click the shield closed. It costs a little more than some, but after all, it is protecting your head! April 14, 2014
Amazing Helmet! I went back and forth on what helmet to get. I have a standard 650 cruiser and just wanted a helmet that would fit well but was stylish. I originally purchased a scorpion helmet but it was heavy and round. The looks of this helmet is awesome. Its fairly quiet, plenty of vents, and fits great with my Cardo system. Also extremely light which I love. All in all, it was a little more than I wanted to spend but totally worth it. Not to mention Revzilla had an incredible sale! April 7, 2014
Very first helmet! Fits great. It's snug. Visor seems a bit flimsy? But airflow seems good. Haven't used it in the dead of summer yet though! Mostly 60 days. Might be slight overkill for daily street riding - which is what I use it for. I might save it for a freeway driving and get another open face… April 7, 2014

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
