Helmet comparison FAQ

KBC FFR vs BOX BX4: what are the main differences?

Looking at the selected models side by side: All listed helmets share the same certification entry: UN ECE REG 22.05. Helmet types differ: FFR (Modular), BX4 (Full face). BX4 is the lightest listed at 1.5 kg; the heaviest is FFR at 1.8 kg (about 0.30 kg apart; weight can vary by size). 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?

FFR is listed with UN ECE REG 22.05. BX4 is listed with UN ECE REG 22.05. On paper they share the same certification entry. 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: FFR: 1.0 stars; BX4: 2.0 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, BX4 maps mid while FFR 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: FFR: 1.8 kg; BX4: 1.5 kg. BX4 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 of these helmets better fits my needs?

It depends on what you prioritise. Conditional cues from the data: prefer a modular shape → lean toward FFR; prefer a full face shape → lean toward BX4; want the lightest listed shell → BX4. Correct size and head shape matter more than any single catalogue field — we cannot know your fit, noise level or ventilation comfort from the database alone, and a single impact-map colour does not crown an “safest” helmet.
