Scorpion EXO-ST1400 Caffeine Helmet | Gear Review

Scorpion EXO-ST1400 Helmet

Scorpion’s new EXO-ST1400 Caffeine is a solid value in the competitive field of midline full-face helmets, boasting several unique features that many more expensive brands don’t offer. Chief among them are its resin-infused 3K carbon fiber shell, and the AirFit cheek pads, which can be rapidly inflated or deflated via onboard valves. The final package is a very lightweight lid with truly individual fit.

The interior is quite well-appointed for a helmet in this price class. Controls for the AirFit cheek pads are in front of the rider’s chin, and can be actuated with gloves on. The cheek pads themselves feature a clearly marked emergency quick-release mechanism, should the need arise. The KwickWick III anti-microbial liner is soft and luxurious, and the crown, cheek pads and neck roll are all easily dismantled and fully washable. A removable “aero skirt” (chin curtain) is included to effectively block wind from blowing up into the chin area, for more comfortable cold weather riding (and reduced road noise, as an added bonus). Generous speaker cutouts beneath the helmet liner can be removed for even more room if desired.

The exterior is equally well designed. The CAD-designed aerodynamic shell itself is constructed of a TCT-U 3K carbon fiber composite weave, which results in extremely light weight – just 3.1 pounds for our size Large test model. Three shell sizes are available over the standard sizing range of S-2XL for a more precise fit. Styling is fresh with aggressive, sporty accents, and the fit and finish on our test model was rich and glossy.

A three-position chin vent aims airflow either at the shield (to help prevent fogging) or direct to the face when fully opened, while another three-position vent at the front peak channels the airflow over the head before exhausting it through a passive vent on the helmet’s rear. The standard clear face shield is scratch resistant, blocks 95% of UVA+B and anti-fog coated. An additional clear shield with a Pinlock anti-fog insert is also included. An integrated drop down tinted sunshield eliminates the need to swap sunglasses on and off during day rides.

Out on the road, the EXO-ST1400 Caffeine was exceedingly functional. The interior has a snug “intermediate oval” shape common in the American market. Because of its light weight, the Scorpion was very comfy on all-day jaunts, with no hot spots or sore points detected after many hours in the saddle. The face shield has solid detents which were effective at speed, and shield sealing against wind noise and water leakage was superb.

My only minor niggle involves the location Scorpion chose for the face shield actuator, which is located directly above the chin vent. As a result, it’s very easy to accidentally toggle the chin vent while opening or closing the face shield. Eventually you get used to it, but with thicker gloves, it becomes harder to avoid. Moving the actuator a bit to the left would solve this issue.

Ultimately, between the carbon fiber shell, AirFit cheek pads, outstanding build quality and overall functionality, it’s clear the Chinese-made, DOT-approved Scorpion EXO-ST1400 Caffeine should be on your very short list if you’re shopping for a midline full face helmet. MSRP is $429.95 in sizes S-2XL. Two colors are available: White (shown) and Phantom.
