Helmet comparison FAQ

What are the main differences between these helmets?

Looking at the selected models side by side: Safety certifications differ — RPHA 11: UN ECE REG 22.05; C10: UN ECE REG 22.06; CS-15: UN ECE REG 22.05; I-70: UN ECE REG 22.05. RPHA 11 is the lightest listed at 1.3 kg; the heaviest is CS-15 at 1.6 kg (about 0.30 kg apart; weight can vary by size). Pinlock-ready anti-fog visor support is listed for C10, CS-15 and I-70 (not all models). These points summarise measurable catalogue fields; fit and real-world comfort still depend on trying the correct size.

Do these helmets have the same safety certification?

RPHA 11 is listed with UN ECE REG 22.05. C10 is listed with UN ECE REG 22.06. CS-15 is listed with UN ECE REG 22.05. I-70 is listed with UN ECE REG 22.05. So the certification entries are not identical across every model. ECE 22.05, ECE 22.06 and DOT are legal approval standards; a SHARP star rating (when present) is a separate independent lab assessment and must not be read as the same kind of result. We do not infer SHARP stars from an ECE mark alone. Verified SHARP ratings on this page: RPHA 11: 3.0 stars; C10: 4.0 stars; CS-15: 4.0 stars; I-70: 4.0 stars.

What do the colours on the impact zone map mean?

Our map stores regional codes on a 1–6 scale (greener ≈ stronger on this page; brown ≈ weaker). When verified multi-speed SHARP point data is present, you can switch 6 / 7.5 / 8.5 m/s and see front-top, front-lower, rear, left and right separately — missing speeds or points show “no data” and are never filled from another speed. Older records may only have the legacy four zones (front/rear/sides) without a verified speed label; those are not placed into the three-speed map. Zone colours are not the same thing as a SHARP star rating. For the models on this page where the safety source is marked SHARP, zone codes are treated as SHARP-linked map data.

How do these helmets compare in front, rear and side impact tests?

Comparing the stored legacy zone codes: at the right side, CS-15 maps mid while RPHA 11 maps weaker; at the left side, C10 maps mid while RPHA 11 maps weaker. These comparisons use the legacy four-zone fields only; impact speed was not verified for the three-speed map.

Which helmet is lighter, and by how much?

Listed weights: RPHA 11: 1.3 kg; C10: 1.5 kg; CS-15: 1.6 kg; I-70: 1.6 kg. RPHA 11 is the lightest in this set, about 0.30 kg below the heaviest. Treat this as catalogue data for a typical size — exact mass can change with size and lining.

Which helmets support Pinlock or have an internal sun visor?

Pinlock-ready anti-fog visor support is marked for C10, CS-15 and I-70 (ready/compatible in our catalogue — not “insert included in the box” unless the retailer says so); not marked for RPHA 11; an internal sun visor is marked for I-70; no internal sun visor flag for RPHA 11, C10 and CS-15.
