Understanding SHARP Testing: What the Ratings Really Mean
The SHARP testing programme, administered by the UK government’s Department for Transport, represents one of the most comprehensive independent helmet safety assessment schemes globally. Unlike manufacturer-funded testing, SHARP purchases helmets directly from retail outlets—ensuring the products tested match exactly what UK motorcyclists buy.
The SHARP Testing Protocol
For every helmet model, SHARP runs 32 impact tests on seven helmets across a range of sizes. These tests evaluate protection across five critical impact zones around the helmet circumference, recognising that real-world crashes can strike from any angle.
The testing methodology includes:
Linear Impact Testing: Helmets are dropped onto flat and kerbstone anvils at three different impact velocities (6.0m/s, 7.5m/s, and 8.5m/s), simulating various crash scenarios from low-speed urban incidents to high-speed motorway accidents.
Oblique Impact Assessment: Recent SHARP protocols incorporate rotational force evaluation, addressing brain injury mechanisms beyond simple linear impacts. This reflects research showing helmet detachment can occur during the accident sequence with reports indicating a frequency varying from 10% to 14% of casualties.
Retention System Strength: All helmets undergo chin strap integrity testing, ensuring the helmet stays on your head during a crash—crucial since an unattached helmet offers zero protection.
Visor Penetration Resistance: Face shield strength testing prevents sharp objects penetrating into the rider’s face during impacts.
Star Rating Interpretation
⭐ (1 Star): Meets minimum ECE requirements but offers limited protection
⭐⭐ (2 Stars): Below-average protection across impact zones
⭐⭐⭐ (3 Stars): Average protection suitable for most riding
⭐⭐⭐⭐ (4 Stars): Good protection across all tested areas
⭐⭐⭐⭐⭐ (5 Stars): Offers good levels of protection right around the helmet
Research by the UK’s Transport Research Laboratory revealed variances of up to 70% in the protective capability of different helmets at selected impact sites. This demonstrates why choosing a high-rated SHARP helmet matters—the difference between 1-star and 5-star protection can literally save your life.
SHARP 5 Star Full Face Helmets Review: What Sets Them Apart
Achieving SHARP 5-star status represents the pinnacle of helmet safety engineering. Only helmets demonstrating exceptional impact protection across all tested zones earn this coveted rating. In our featured selection, four helmets achieved this elite status: the MT Revenge, AGV K1 S, HJC C70, and Shoei NXR2.
The Price-Safety Paradox
One of SHARP testing’s most remarkable revelations challenges conventional wisdom: price doesn’t correlate with safety performance. The £65 MT Revenge protects as effectively in SHARP testing as the £430 Shoei NXR2. Both earned maximum 5-star ratings.
So why the £365 price difference? Premium helmets justify costs through:
Advanced Materials: Composite fibre shells (carbon, Kevlar, fibreglass) weigh less than polycarbonate whilst maintaining equal or superior strength. The Shoei NXR2’s 1,390g versus the MT Revenge’s 1,400g seems negligible, but over eight-hour touring days, every gramme matters.
Refined Aerodynamics: Wind tunnel development reduces buffeting, lift, and noise—crucial for concentration during long motorway miles. The AGV K1 S features MotoGP-derived aerodynamics reducing drag by 4% compared to standard designs.
Superior Ventilation: Multiple adjustable vents with optimised internal channelling keep riders comfortable across temperature ranges. Budget helmets typically offer basic ventilation that struggles in British summer heatwaves or winter dampness.
Build Quality: Premium helmets feature superior paint finishes, smoother visor mechanisms, plush interior fabrics, and meticulous quality control. The Shoei NXR2’s four shell sizes ensure optimal proportional fit—budget single-shell helmets compromise here.
Longevity: Quality materials and construction mean premium helmets often outlast cheaper alternatives. A £400 helmet lasting six years represents better value than replacing a £100 helmet every two years.
Safest Full Face Motorcycle Helmets SHARP Rated
Beyond our featured seven, several other SHARP 5-star full face helmets deserve honourable mentions:
HJC FG-ST: Fibreglass construction achieving maximum safety at around £200
Bell Race Star: Premium carbon fibre track helmet favoured by circuit riders
Scorpion EXO-R1 Air: Sport-touring excellence with advanced ventilation
Shark Skwal i3: Innovative LED lighting combined with 5-star protection
All of these helmets are available through UK retailers and Amazon.co.uk, providing options across budgets whilst maintaining elite safety credentials.
Integral Helmet SHARP 5 Star Rating: Construction Matters
The term “integral helmet” refers to full-face designs providing complete head protection including the chin bar—distinguishing them from open-face or modular alternatives. SHARP 5-star integral helmets share specific construction characteristics worth understanding.
Shell Materials Decoded
Polycarbonate/Thermoplastic: Budget-friendly materials offering excellent impact absorption through controlled deformation. The MT Revenge and HJC C70 utilise these materials effectively. Contrary to popular belief, polycarbonate helmets can achieve equal safety to expensive composites—SHARP testing proves this conclusively.
Composite Fibre: Combinations of fibreglass, carbon, and Kevlar create lightweight shells distributing impact forces efficiently. The Shoei NXR2’s AIM+ construction and Caberg Drift Evo’s tri-composite design exemplify this approach.
Multi-Shell Sizing: Premium manufacturers produce different shell sizes accommodating the size range rather than padding a single shell differently. The Shoei NXR2’s four shell sizes ensure a small rider doesn’t wear a large shell stuffed with padding—improving both safety and aesthetics.
EPS Liner Technology
The expanded polystyrene (EPS) liner inside the shell actually absorbs most impact energy through controlled crushing. Advanced helmets like the AGV K1 S employ multi-density EPS—varying foam densities across impact zones optimise protection whilst maintaining comfort.
Single-impact versus multi-impact debate often arises. Most motorcycle helmets, including all SHARP-tested models, use single-impact EPS designed to crush during one severe impact. After any crash, replace your helmet immediately—even without visible damage, the EPS has likely compressed and lost protective capability.
Oblique Impact Testing Results: Rotational Force Protection
Research highlighted that the temporal fossa (temple) is particularly vulnerable to injury and helmet design should provide more protection. Modern SHARP testing increasingly emphasises oblique (angled) impacts generating rotational forces—a primary cause of traumatic brain injury.
Why Rotational Forces Matter
When your head strikes the ground at an angle (the most common real-world scenario), the helmet rotates rapidly. This rotation twists your brain inside your skull, stretching and tearing neural tissue. Linear impact testing alone doesn’t capture this mechanism.
The latest ECE 22.06 standard, which the AGV K1 S and Shoei NXR2 meet, incorporates oblique impact testing for the first time in European regulations. Helmets must now demonstrate controlled rotational acceleration during angled impacts.
SHARP’s Oblique Testing Protocol
SHARP evaluates helmets using oblique impacts at multiple velocities and impact points. Helmets achieving 5-star ratings demonstrate superior rotational force management—your brain experiences less dangerous twisting motion during crashes.
Some manufacturers incorporate specific rotational protection technologies:
MIPS (Multi-directional Impact Protection System): A low-friction liner allowing the helmet to rotate slightly independently of the head, reducing rotational forces transferred to the brain.
Internal Shell Designs: Optimised EPS configurations and shell shapes minimise rotation naturally without additional systems.
Whilst our featured SHARP 5-star helmets don’t necessarily include MIPS, their designs inherently manage rotational forces effectively enough to achieve maximum ratings in oblique testing.
Retention System Strength Tested: Why Your Helmet Stays Put
The strongest helmet becomes worthless if it departs your head during impact. Research highlighted helmet detachment can occur during the accident sequence with reports indicating a frequency varying from 10% to 14% of casualties. SHARP testing rigorously evaluates retention system integrity.
Double-D Ring Systems
The Shoei NXR2, AGV K1 S, and Caberg Drift Evo employ Double-D ring retention—two metal D-rings through which the helmet strap threads. This system:
Never Loosens: Unlike buckle systems potentially wearing over time, Double-D rings maintain consistent tension indefinitely.
Provides Redundancy: Even if one D-ring fails (extremely rare), the second maintains helmet attachment.
Offers Infinite Adjustability: Perfect fit regardless of neck circumference or winter jacket collar thickness.
The learning curve for Double-D systems initially frustrates some riders. Practice threading the strap at home until the motion becomes automatic—your muscle memory will thank you during frantic pre-ride departures.
Micrometric Buckle Systems
The MT Revenge, HJC i70, HJC C70, and LS2 FF320 Stream Evo feature micrometric buckles—ratcheting mechanisms securing with a simple click. Benefits include:
Single-Handed Operation: Push the button, pull the strap—helmet removes in seconds.
Quick Fastening: Click once and you’re secured, ideal for frequent stops.
Passenger-Friendly: Easier for less experienced pillions to operate correctly.
Quality micrometric buckles achieve equal retention strength to Double-D systems. SHARP testing confirms all our featured helmets’ retention systems withstand extreme forces without failure.
The Emergency Quick Release System (E.Q.R.S.)
Premium helmets like the Shoei NXR2 incorporate E.Q.R.S. technology—emergency responders can remove cheek pads rapidly without lifting the helmet off an injured rider’s head. This prevents potential spinal injury during helmet removal following crashes.
Whilst not a SHARP testing criterion, E.Q.R.S. represents another safety layer worth considering, particularly for track-day enthusiasts or riders covering significant motorway miles where emergency services might need quick access.
Visor Penetration Resistance: Protecting Your Face
All of the major helmet test standards include a test to determine whether the chin bar on Full‐Face or System (Flip-Front) helmets have sufficient mechanical strength to protect the face and jaw from injury during an impact. SHARP evaluates both chin bar integrity and visor penetration resistance.
Why Visor Strength Matters
During crashes, road debris, barrier posts, or vehicle components can strike your face shield. A weak visor shatters, allowing objects penetrating through to your face and eyes. All our featured helmets employ optically-correct polycarbonate visors resisting penetration whilst maintaining optical clarity.
Pinlock Anti-Fog Technology
British weather demands fog-free vision. Pinlock systems create double-glazed visor assemblies trapping an insulating air layer preventing condensation. Several featured helmets include Pinlock inserts:
Included: Shoei NXR2 (Pinlock Evo), MT Revenge (Pinlock insert), Caberg Drift Evo (Pinlock Max Vision)
Pinlock-Ready (Purchase Separately): AGV K1 S, HJC i70, LS2 FF320 Stream Evo
Budget £20-£35 for aftermarket Pinlock inserts—a worthwhile investment preventing dangerous vision obstruction during winter commutes or damp touring days.
Photochromic and Tinted Visors
Many riders maintain multiple visors for varying conditions:
Clear: Default option for all-weather riding and night use
Tinted/Smoke: Reduces glare during bright conditions
Photochromic: Automatically darkens in sunlight, lightens in shade
Yellow/Orange: Enhances contrast during overcast, foggy conditions
The HJC i70 and LS2 FF320 Stream Evo feature integrated drop-down sun visors—convenient alternatives to swapping external visors, though less effective than photochromic shields for rapidly changing light.
UK Legal Note: Tinted visors unsuitable for night riding. Only use dark visors during daytime. Photochromic visors must transmit minimum 50% light when clear to remain road-legal after dark.

How to Choose SHARP Tested Full Face Helmets: 7-Step Guide
Selecting the optimal helmet involves more than identifying the highest SHARP rating at your budget. Follow this systematic approach ensuring both safety and comfort:
Step 1: Determine Your Head Shape
Motorcycle helmets accommodate three primary head shapes:
Round Oval: Equal front-to-back and side-to-side dimensions (suits Shoei NXR2)
Intermediate Oval: Slightly longer front-to-back than side-to-side (most common, suits AGV K1 S, HJC models)
Long Oval: Significantly longer front-to-back measurement (suits some HJC models)
Measure your head’s circumference 2.5cm above your eyebrows using a flexible tape measure. Note the measurement in centimetres, then consult manufacturer sizing charts. Remember: sizes aren’t standardised—an XL from AGV fits differently than an HJC XL.
Step 2: Prioritise SHARP Ratings Within Budget
Identify your maximum budget, then select the highest SHARP-rated helmet within that range. Our analysis demonstrates excellent 4-5 star options exist across all price brackets:
Under £100: MT Revenge (5⭐), LS2 FF320 Stream Evo (4⭐)
£100-£200: HJC C70 (5⭐), AGV K1 S (5⭐), HJC i70 (4⭐)
£200+: Caberg Drift Evo (4⭐), Shoei NXR2 (5⭐)
Step 3: Consider Your Primary Riding Style
Different riding demands require specific features:
Sport Riding: Prioritise aerodynamics, lightweight construction, aggressive ventilation (AGV K1 S, Caberg Drift Evo)
Touring: Value comfort, noise reduction, convenient features like sun visors (HJC i70, Shoei NXR2)
Commuting: Balance all-weather versatility, integrated sun visors, easy maintenance (HJC C70, HJC i70)
Track Days: Seek maximum ventilation, lightweight designs, E.Q.R.S. capability (Shoei NXR2, Caberg Drift Evo)
Step 4: Evaluate Ventilation Requirements
British weather varies dramatically—your helmet needs adaptable airflow:
Summer Riding: Multiple adjustable intake vents, efficient exhaust channels
Winter Riding: Closeable vents preventing excessive cold air, breath deflectors minimising visor fogging
Year-Round: Versatile systems like the AGV K1 S’s multi-position vents
Test vent controls whilst wearing gloves—awkward adjusters become frustrating during rides.
Step 5: Assess Vision and Visor Features
Clear vision isn’t negotiable. Prioritise helmets offering:
Pinlock Ready Visors: Essential for British conditions (all featured helmets)
Wide Peripheral Vision: 190° horizontal field of view (AGV K1 S excels)
Tool-Free Visor Changes: Quick swaps between clear, tinted, photochromic options
Integrated Sun Visors: Convenient alternative to multiple visors (HJC i70, HJC C70, LS2 FF320, Caberg Drift Evo)
Step 6: Consider Weight and Comfort
Lighter helmets reduce neck strain during extended rides:
Lightweight Champions: Caberg Drift Evo (1,350g), HJC C70 (1,350g), Shoei NXR2 (1,390g)
Standard Weight: AGV K1 S (1,442g), MT Revenge (1,400g)
Heavier Options: HJC i70 (1,519g), LS2 FF320 (1,550g)
For perspective, a 200g difference (similar to adding a smartphone) becomes noticeable during eight-hour touring days.
Step 7: Try Before Buying When Possible
Order multiple sizes from Amazon.co.uk if uncertain—their returns policy accommodates this. A properly fitting helmet should:
Feel Snug Initially: Cheek pads compress slightly, interior settles during first weeks
Create Even Pressure: No specific pressure points on forehead, cheeks, or crown
Stay Immobile: Grab the helmet whilst keeping your head still—minimal movement indicates correct fit
Allow Comfort for 20+ Minutes: Wear around the house—immediate headaches signal poor fit
UK Regulations and Standards: What You Need to Know
Legal Requirements for Motorcycle Helmets
All motorcycle helmets sold in the UK must display ECE 22.05 or ECE 22.06 certification markings. Post-Brexit, the UKCA (UK Conformity Assessed) marking increasingly appears alongside or replacing CE marks—both remain valid.
Legal Minimum Standards:
- ECE 22.05 or 22.06 certification
- Proper labelling including size, manufacturer, certification number
- Chinstrap rated to withstand specific retention forces
Interestingly, UK law doesn’t mandate SHARP testing—helmets need only ECE certification. However, SHARP points out that there is a 70% difference in protection between a SHARP one star rating compared to their five star rating, making SHARP ratings valuable guidance beyond legal minimums.
ECE vs. DOT vs. Snell Certifications
ECE (Economic Commission for Europe): European standard requiring comprehensive impact testing, penetration resistance, retention system evaluation. Mandatory in UK and Europe.
DOT (Department of Transportation): US federal standard. Whilst valid for American sales, ECE generally considered more rigorous. Some helmets carry both certifications.
Snell Memorial Foundation: Voluntary premium standard exceeding ECE/DOT requirements. Snell-certified helmets undergo additional testing but SHARP ratings provide equivalent rigour for UK buyers.
Helmet Replacement Guidelines
Replace your helmet:
After Any Impact: Even seemingly minor drops can compromise EPS integrity
Every Five Years Maximum: Materials degrade through UV exposure, temperature cycles, general ageing

Conclusion: Choosing Your Perfect SHARP Tested Helmet
Selecting the optimal SHARP tested full face helmet ultimately balances three factors: safety performance, comfort features, and budget constraints. Our comprehensive analysis demonstrates that exceptional protection exists across all price brackets—from the remarkable £65 MT Revenge achieving maximum 5-star SHARP rating to the premium £430 Shoei NXR2 delivering refined long-distance comfort.
The most crucial takeaway? SHARP provides clear advice on how to select a helmet that fits correctly and is comfortable, and secondly provides consumers with clear, impartial and objective information about the relative safety of motorcycle helmets available to riders in the UK. Use this independent government-funded testing as your primary safety guide.
For budget-conscious riders, the MT Revenge and HJC C70 prove safety needn’t require financial sacrifice. Mid-range options like the AGV K1 S deliver Italian engineering excellence with ECE 22.06 certification under £180. Premium seekers wanting absolute refinement will appreciate the Shoei NXR2’s Japanese craftsmanship and four shell-size optimization.
Remember that the safest helmet remains the one you actually wear correctly every single ride. Prioritise proper fit over brand prestige, SHARP ratings over marketing claims, and verified Amazon.co.uk availability over unavailable “ideal” helmets. Your life depends on making an informed, evidence-based choice—SHARP testing provides exactly that evidence.
Visit SHARP’s official database to research additional models, verify ratings for helmets you’re considering, and stay current with newly tested products. British motorcyclists enjoy access to the world’s most comprehensive independent helmet testing programme—use this advantage wisely.
