Kaiju II is one of two character-led graphics in this range, and it is the more aggressive of them — red and white worked over a black base into something deliberately monstrous.

1350 grams, and why that is the headline

🔵 A light helmet is also a quieter one to wear over distance, in an indirect way: less mass means less buffeting when your head is pushed around by turbulence, and less correction from your neck to keep it steady.

1350 g ±50 g, mid-size shell.

HPTT shell, three shell sizes and ECE 22.06

🔵 The oblique impact test added in 22.06 is the most consequential change in three decades of European helmet approval. Rotation is behind a large share of serious head injuries, and 22.05 had no test for it at all.

The Rapid III is homologated to the current standard.

No independent safety rating — and the trap that goes with it

🔵 The absence of a rating is worth weighing rather than dismissing. It means nobody independent has measured this helmet's impact performance — so the only evidence available is that it meets ECE 22.06, which is the legal minimum.

For many riders at this price that is a reasonable basis. It should be a decision rather than an assumption.

About the Kaiju II graphic

Illustrative graphics are a different proposition from abstract ones and should be judged differently. An abstract pattern of shards and sweeps is safe: it offends nobody, it dates slowly, and it is more or less forgettable. A graphic with a subject is a commitment — you either want to wear it or you do not, and you will know within a second. What makes this one wearable rather than costume is the restraint of the palette: red and white on black is a conventional motorcycling combination, so from more than a few metres the helmet reads as a red and black lid and only resolves into artwork close up. 🔵 Practically it behaves like a dark helmet in poor light, offset a little by the white elements. Printed artwork of this complexity cannot be touched in after damage — a deep scratch is permanent in a way it would not be on a solid colour. Between the two illustrated graphics, Kaiju II is the more composed: it has a centre, it is broadly symmetrical, and it reads as a designed object rather than a scene. Zombie II is the looser of the pair. If you are choosing between them, look at photographs of both from the side as well as the front — that is where the difference between them is largest.

What this helmet does not have: an internal sun visor

🔵 No internal sun visor, and no photochromic visor offered for this model either. Glare management on the Rapid III means either sunglasses or a second visor you swap by hand.

Replacement visors in tints are available separately.

Chin and top intakes, channelled EPS

In summer the crown intake does the work; in winter you close everything and rely on the chin curtain and an anti-fog insert.

🔵 The insert is not supplied — the visor is prepared for a Pinlock 70 MaxVision, sold separately.

Anti-fog — prepared for, not supplied

🔵 Fogging is what stops most riders in November, and it is entirely solvable. The Rapid III supplies two thirds of the solution — a chin intake feeding the visor, and a breath deflector — and leaves the last third to you.

Buy the Pinlock 70 MaxVision at the same time as the helmet.

Lining, closure and everyday comfort

🔵 Replacement cheek pads in other thicknesses are the most useful spare LS2 sells and the least often bought. A helmet that has loosened over two seasons is usually fixed with thicker pads rather than replaced.

The complete lining is available separately too.

Where it sits in LS2's range

🔵 The Rapid III replaced the FF353 Rapid and is a different helmet on a different standard — ECE 22.06 rather than 22.05, a different shell, and no inherited test result.

Reviews and ratings of the older model do not describe this one.

Care and replacement parts

🔵 A visor is a consumable. Once it is scratched enough to flare at night, replace it rather than living with it — the cost is small and the difference in night vision is not.

Clear replacements and the Pinlock 70 MaxVision insert are both available.

In the box

• LS2 FF820 Rapid III helmet — Kaiju II, Black, red and white (HPTT shell)
• Clear outer visor, fitted
• Chin curtain, fitted and removable
• Breath deflector, fitted and removable
• 🔵 No internal sun visor — this model does not have one
• 🔵 No Pinlock insert — the visor is prepared for a Pinlock® 70 MaxVision™, which is sold separately
• 🔵 No second visor and no intercom — both are separate purchases

Size guide

🔵 Sizes at the extremes benefit most from three shells. A 3XL built on a shell sized for it is proportioned correctly; one built on an XL shell with thin padding is neither comfortable nor properly protective.

This helmet splits 2XS–S, M–L and XL–3XL.

Specification

• Model — LS2 FF820 Rapid III
• Part number — 168200632
• Colour — Kaiju II — Black, red and white
• Homologation — ECE 22.06
• 🔴 Safety rating — none. SHARP has no entry for the FF820, Rapid III or Rapid 3 (brand list checked directly). The 2-star result under „FF353 Rapid" belongs to the previous-generation helmet — different shell, different standard — and is deliberately not carried over. No ADAC or Certimoov result either
• Shell — HPTT injection-moulded thermoplastic; three shell sizes (2XS–S / M–L / XL–3XL)
• Weight — approx. 1350 g (±50 g), mid-size shell without accessories
• Sizes — 2XS to 3XL (eight sizes)
• 🔴 Sun visor — none. This helmet has no drop-down internal shield — unlike LS2's FF808 Stream II, FF811 Vector II and FF817 Challenger II. It is most of the reason it weighs 1350 g
• Visor — clear outer visor, scratch-resistant, tool-free change
• 🔴 Anti-fog — prepared for Pinlock® 70 MaxVision™ — the insert is NOT included. The pins are fitted; the lens is a separate purchase
• Ventilation — chin and top intakes feeding channelled EPS, with rear exhausts — two intake paths, one more than the FF817. 🔵 Assessed from the published construction; no independent airflow measurement exists
• 🔴 Wind noise — left unrated — no independent measurement is published for this model
• Retention — ratchet buckle
• Interior — hypoallergenic, antibacterial, fully removable and washable. 🔵 No branded wicking fabric (no COOLMAX or X-Static) and no magnetic wind deflector — both appear further up LS2's range
• Included — chin curtain and breath deflector, both fitted and removable
• 🔴 FIM homologation — none — a road helmet, not eligible for FIM-sanctioned competition
• Serviceability — visors, cheek pads in several thicknesses, complete lining, chin curtain, breath deflector and vent covers all available separately
• Replacement guidance — after about five years regardless of condition, and immediately after any impact

• 1× helmet
• Carrying bag
• Reflective stickers
