A racing surname on a touring-capable helmet is a statement of intent rather than a track ticket: this decor carries Sylvain Guintoli's name across a white shell broken up by red and light-blue diagonal graphics over the carbon weave, more paddock energy than the quieter finishes lower down this range. Shark's own supplier data gives no season for this particular graphic, and none is guessed here -- what follows is the same carbon-fibreglass Sport-GT platform under every decor in this line, not a track-only construction borrowed for the name.

ECE 22.06, not a racing homologation

Skip the livery for a moment: what actually got tested here is UNECE R 22-06. It hits the shell at more points than the old 22.05 rule did, at several speeds per point, and it scores rotational impact, something 22.05 never measured. A racing surname on a shell does not change which standard applies underneath it.

What the carbon shell buys, and what it does not

Fiberglass woven together with carbon is how Shark's own listing describes this shell, filed under "Fibre" rather than a solid carbon-aramid category, built around a foam core stepped through multiple density zones across two distinct shell moulds. It is a genuine, measurable upgrade over the plain-fibreglass Spartan GT Pro -- lighter for the same shape -- without pretending to be the heavier material of a track-only carbon shell costing far more.

Carrying the weight over a track day or a long ride

1,465 g is Shark's number for the first shell size; the second, larger mould adds a touch more. That figure matters less in the pit lane than forty minutes into a ride, when muscles holding a static load start to feel it -- extra mass accumulates rather than announcing itself early.

Airflow: three in, two out, and a real off switch

Shark's double-Venturi layout draws air through three front intakes and out through two rear extractors, engineered to keep working before the bike reaches motorway speed. Visordown's independent test found both chin-bar intakes and the rear exhaust ports genuinely shut, so the same shell that vents hard in summer seals up for winter -- the same review calls the resulting airflow decent without rating it best-in-class.

The VZ300 visor: central lock, Pinlock fitted, tint limits

This decor uses the same visor platform as the Spartan RS and Spartan RS Carbon -- shared hardware, not a cut-down part. Glazing spans 2.8 mm to 2.2 mm through its profile, held by a central grip and central lock instead of a side catch, and arrives with a clear Pinlock 120 insert already mounted. Blue, pink and red iridium suit daytime road use; smoke, silver and rainbow stay for the track only.

Everyday details: sun visor, glasses, intercom

A UV380 anti-fog sun visor drops with one slider on the outside, workable with a gloved hand at a stop. The 4-point mount comes apart tool-free for cleaning, there's a groove cut for glasses arms, and this lid is listed as compatible with both Shark's own Sharktooth unit and SENA comms.

What is actually protecting the rider's head

Impact absorption comes from an EPS liner graded across several firmness zones, and the chin strap uses a double-D ring rather than a buckle that can loosen under load. Cheek pads pull free via Shark's Emergency Release hardware, sparing an injured rider's neck any twisting -- the same job an EQRS does, whatever the badge reads. MIPS does not appear anywhere in Shark's own documentation for this helmet, and it is not claimed here.

Interior fit and cleaning

ALVEOTECH antimicrobial fabric lines the inside, shaped into 3D morphological cheek pads per the collection copy rather than flat pads bulking out a gap. Independent testing confirms the pads, neck roll and skull cap all come out for a wash, not just the cheek pads alone. Six sizes, XS through XXL, split across the two shell moulds used throughout this range.

Sylvain Guintoli, and this graphic

Sylvain Guintoli is a French rider best known for winning the 2014 World Superbike championship and for a long-running role as Suzuki's MotoGP test and wildcard rider. Shark's own price and range data for this decor give a designation of "SPARTAN GT PRO CARBON GUINTOLI" with no season attached to it, and none is stated here as a result -- this is a name livery, not dated to a specific year of competition, and it is described that way rather than assigned a year that was never in the source data.

The Spartan ladder, and where the Replica tier sits on it

Four real price steps exist in Shark's own data, not an invented number for this text: Spartan RS Fibre opens the range, Spartan RS Carbon adds the lighter shell, the non-carbon Spartan GT Pro brings the Sport-GT layout and sun visor without a carbon shell, and Spartan GT Pro Carbon tops it. Within this top step, plain finishes are the entry point and graphics like this one sit at the range's own Replica pricing -- the premium over the plain Skin decor buys the graphic and the name, not a different shell or a different certificate.

On wind noise

We can't point to a trustworthy decibel reading for this helmet, so this listing does not manufacture one. BikeSocial's road test of the 22-06 generation credits a tighter, elasticated neck roll built specifically against wind noise, at the cost of a slightly harder helmet to don. Visordown separately describes the noise in ordinary use as kept to a relative minimum. Both are editorial impressions, not lab data.

Replacement visors

A dedicated Shark visor listing fits both the RS and GT Pro ranges; the Range Book shows this VZ300 hardware carried across three related Spartan models rather than built just for this one. Whatever tint gets scratched or outgrown, a replacement exists.

Limitations, without spin

No MIPS or equivalent system is fitted, and none is claimed. This visor platform is not documented as tear-off compatible, unlike Shark's purpose-built track lids. SHARP's database holds a different, 2021-tested helmet named "Spartan GT Carbon" at 4 stars -- no "Pro" in that name -- and that rating is not transferred here.
