How to measure your helmet size correctly: To find the right helmet size, measure your head circumference with a flexible tape measure.
It is important that the tape measure runs around the widest part of the head – only then will you get a correct result.
Place the tape measure at the front, about 1–2 cm above the eyebrows, and run it along the sides above the ears.
At the back, the tape must run over the largest part of the back of the head (not too low on the neck). The tape may run slightly at an angle – what matters is that it sits all the way around the largest points of the head.
Make sure the tape measure sits snugly but does not dig in. Measure 2–3 times for the most accurate result. You can then compare the measured value in centimetres (cm) with our size chart.
Tips for an accurate result
- Keep hair flat (e.g. do not measure over a voluminous hairstyle)
- Keep the tape horizontal, i.e. along the largest circumference
- Do not measure too loosely
- For values between two sizes:
→ usually choose the larger size (depending on helmet model / fit)
Important note on fit
The right helmet should fit firmly without causing uncomfortable pressure points.
A new helmet may feel a little tighter at first, as the inner lining adapts slightly over time.

The Suomy SR-GP Evo Infrared in its striking white, black and red livery is a helmet that earns its place on both your daily commute and the circuit. Developed with direct input from MotoGP and road-racing professionals, it packages world-class protective technology into a shell you can actually wear every day — light enough not to fatigue you on the way to work, aerodynamically refined enough to stay planted at track-day speeds.
Key Features
- Tricarboco shell constructed from carbon, Kevlar and fibreglass fibres bonded with high-strength aramid resins — approx. 1,450 g ±50 g in size M
- Wind-tunnel-optimised aerodynamics with a measured drag coefficient (Cx) of just 0.39, reducing neck fatigue on long rides and fast straights alike
- Exceptional field of view — 92° vertical and 210° horizontal — for complete situational awareness in traffic or on track
- Pinlock MaxVision 120 anti-fog insert included as standard, covering edge-to-edge for clear vision in cold, wet or variable conditions
- Five large forehead and chin vents plus two recessed exhaust vents and an integrated rear spoiler create a venturi effect that actively extracts warm air
- Premium removable, washable and hypoallergenic interior with emergency quick-release cheek pads and camelback hydration preparation
- Double-D-ring retention system — the benchmark closure for competition use, precise and reliable
Shell Construction
Suomy's Tricarboco layup combines carbon, Kevlar and fibreglass in a matrix of high-strength aramid resin to produce a shell that punches well above its weight class. Four distinct shell sizes (S, M, L, XL) ensure that each helmet fits the correct mould rather than relying on padding alone to bridge size gaps — a detail that matters as much for everyday comfort as it does for certification compliance. Outstanding vibration and torsional stability means the structure absorbs energy efficiently across a wide range of impact scenarios.
Aerodynamics
A drag coefficient of 0.39 is the product of serious wind-tunnel hours, not a marketing claim. At motorway cruising speeds the integrated spoiler generates downforce that keeps the helmet tracking straight, and in a tucked riding position the shell produces no unsettling lift. For regular road use this translates directly into less neck strain on longer journeys — a meaningful everyday benefit that racing-derived aero delivers even when you're nowhere near a circuit.
Visor System
The polycarbonate visor is manufactured with variable thickness for optical clarity across its full sweep. The lens is scratch-resistant and can be swapped without tools in seconds — a practical convenience that becomes genuinely important when a visor gets damaged between rides. The metal Racing Lock System retains the visor securely under all conditions and resists the kind of gradual loosening that cheaper mechanisms can develop over time. The Pinlock MaxVision 120 insert, the highest-rated anti-fog class available, is included in the box and covers the full visor area for uncompromised vision in cold mornings, autumn rain and the humidity of a pit lane.
Ventilation
Five generously proportioned air inlets at the forehead and chin channel fresh air through optimised EPS ducting directly across the rider's face. Two flush-mounted exhaust vents at the rear work in concert with the integrated spoiler to generate a venturi effect, actively drawing warm air out rather than relying on passive escape. Whether you're filtering through city traffic or completing a long motorway transfer before a trackday, the ventilation system is genuinely effective at keeping the interior comfortable.
Interior
The liner uses high-tech moisture-wicking fabrics that are soft, lightweight and hypoallergenic — suitable for sensitive skin even on multi-hour rides. The cheek pads incorporate an emergency quick-release system for first responders, and the entire interior is removable, machine washable and available as a replacement part. A camelback port is integrated for riders who want hydration without removing the helmet, a detail borrowed directly from grand prix practice.
Fitment & Compatibility
The Suomy SR-GP Evo is a universal full-face helmet suitable for any rider seeking a premium road or track helmet. No motorcycle-specific fitment restrictions apply. Available in sizes XS through XXL to suit a wide range of head circumferences.
| Size | XS | S | M | L | XL | XXL |
|---|---|---|---|---|---|---|
| Head circumference (cm) | 53–54 | 55–56 | 57–58 | 59–60 | 61–62 | 63 |
Racing helmets are designed to fit snugly. If you fall between two sizes, choose the smaller — the liner will compress slightly with use and settle to the correct fit.
