Introduction

At Moto Central, safety is paramount. As one of the UK’s leading motorcycle helmet retailers, we aim to provide riders with not just the best products but also the most accurate and comprehensive information to make informed decisions. This includes exploring the strengths—and limitations—of the Safety Helmet Assessment and Rating Programme (SHARP).

While SHARP offers a valuable framework for comparing helmet safety, there are valid criticisms of its methodology and the clarity of its results. This article will delve into SHARP’s purpose, testing process, strengths, and shortcomings, enabling our customers to evaluate its significance when choosing a helmet.


SHARP: A Brief Overview

The SHARP initiative was launched in 2007 by the UK Department for Transport (DfT) to supplement the ECE 22.05 standard (now updated to ECE 22.06). Unlike the pass-or-fail certification process mandated by law, SHARP provides 1–5-star safety ratings for helmets, claiming to help riders choose helmets that exceed the minimum safety requirements.

SHARP was based on the COST 327 report, a 2001 European Commission study investigating helmet safety. However, some key deviations from this report’s recommendations have sparked criticism, particularly concerning the testing methodology.


The Good: What SHARP Gets Right

  1. A Step Beyond Minimum Standards:

    The ECE 22.05 and 22.06 regulations provide a baseline for helmet safety but do not differentiate between helmets offering higher levels of protection. For example, a £25 helmet can meet the same certification standard as a £500 helmet, leaving riders with little insight into the relative safety of different models. SHARP addresses this gap by offering comparative star ratings.

  2. Emphasis on Fit and Comfort:

    SHARP also advocates the importance of fit and comfort, recognising that even the best-rated helmet cannot protect if it doesn’t fit securely. A helmet that is too loose may detach in a crash, contributing to 10–14% of motorcyclist fatalities.

  3. Life-Saving Potential:

    SHARP estimates that if all riders wore highly rated helmets, 50 lives could be saved annually. This underlines the importance of selecting helmets that exceed minimum standards.


The Controversy: Criticisms of SHARP

1. The Origin of SHARP

When the UK adopted the ECE helmet certification protocol upon joining the EU, the longstanding BSI standard for helmets was phased out. To fill the void, SHARP was developed as an additional rating system. Some have suggested this was less about improving safety and more about utilising existing resources from the BSI testing team.

2. Headform Issues

SHARP’s decision to use solid headforms instead of biometric headforms is one of the most contentious points. Biometric headforms, as recommended by COST 327, more accurately mimic the human head’s composition and provide realistic data on impact absorption. Solid headforms are cheaper but less representative of real-world conditions. Critics, such as Dr. Nigel Mills from Birmingham University, argue this significantly undermines the accuracy of SHARP’s ratings.

3. Unagreed Test Criteria

The energy absorption levels used to determine SHARP ratings were not agreed upon by independent experts. There was no public consultation or industry-wide consensus on how helmets should be scored, leading to questions about the validity of the star ratings.

4. Questionable Results

One of SHARP’s earliest five-star ratings went to a £50 Lazer helmet, while some premium helmets from racing-focused brands scored lower. This raised eyebrows among manufacturers and retailers alike. Are budget helmets truly as safe as premium models? Or does SHARP’s methodology favour certain designs, such as heavy edge mouldings on thermoplastic helmets?

5. Randomness and Skepticism

Many in the industry, including respected helmet manufacturers, view SHARP as flawed and unrepresentative of real-world conditions. Some manufacturers dismiss SHARP outright, considering it a niche UK initiative with little relevance to global helmet safety standards.


How SHARP Tests Helmets

Despite these criticisms, SHARP’s testing process is rigorous:

  • Helmet Selection: SHARP tests helmets based on public requests, market trends, and innovative designs. Helmets are purchased independently from UK retailers to ensure impartiality.
  • Impact Testing:
    • Helmets are subjected to impacts at multiple points, including the front, rear, sides, and crown, replicating crash scenarios.
    • Rotational acceleration testing aligns with ECE standards.
    • For modular helmets, the chin bar locking mechanism is tested for durability, with results expressed as a “latch score.”
  • Star Ratings: Complex data is translated into 1–5 stars, with higher ratings indicating greater protection.


What SHARP Doesn’t Test

  • Chin Strap Safety: No specific tests are conducted on chin strap mechanisms.
  • Noise Levels: While noise can affect rider comfort and concentration, SHARP does not evaluate helmets for acoustic properties.
  • Puncture Resistance: SHARP focuses on impact absorption, as penetration injuries are rare in road accidents.


Conclusion: A Balanced Approach

At Moto Central, we believe in balancing SHARP ratings with real-world considerations:

  1. Fit: The most critical factor. A poorly fitting helmet, regardless of its SHARP rating, offers inadequate protection.
  2. Comfort: Essential for maintaining focus and reducing fatigue on long rides.
  3. Quality: Premium helmets often feature superior materials and rigorous in-house testing, providing confidence beyond SHARP ratings.

If SHARP evolves to address its methodological shortcomings, it could become an invaluable resource for riders. Until then, we recommend using SHARP ratings as one of many factors when choosing a helmet.

Ultimately, a good helmet is the one that fits you, protects you, and is comfortable enough to wear on every ride. Visit us in-store or online, and our experts will help you find the perfect helmet to suit your needs.
