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 KYT TT-Revo in Speeding White/Red is a statement of motion before the engine is even started. Sharp, flowing graphics draw the eye across a crisp white base, with red accents that pulse with energy — a design language rooted in KYT's racing heritage and translated here for riders who demand a helmet that looks as fast as it rides. Certified to ECE 22.06 and weighing in at approximately 1,500 g (±50 g, size S), the TT-Revo proves that striking design and genuine safety need not be a compromise.
Key Features
- ECE 22.06 certified full-face helmet — approved for road use across Europe
- ADT Advanced Thermoplastic shell construction delivers strong impact resistance at a manageable weight of approx. 1,500 g (±50 g, size S)
- Three shell sizes (covering XS through XXL) ensure a genuine fit rather than a padded-out compromise
- Visor Lock mechanism keeps the Pinlock MaxVision 70-ready polycarbonate visor firmly seated at speed; tool-free visor changes in seconds
- Bi-elastic, removable and washable liner with replaceable cheek pads — comfortable for spectacle wearers
- Bluetooth-ready interior with provision for a universal intercom system
Design, Finish and Heritage
KYT built its reputation on the track, and the Speeding graphic on the TT-Revo carries that lineage into everyday riding. The white base shell is dressed in purposeful red detailing that follows the helmet's aerodynamic contour lines rather than sitting on top of them — the result is a graphic that feels engineered rather than applied. Clean transitions between colour fields and a consistent finish quality make the TT-Revo stand out in a segment where graphics often look rushed or generic. This is the helmet for riders who want their kit to reflect an appreciation for design.
ADT Shell and Passive Safety
The outer shell is formed from ADT Advanced Thermoplastic, a material chosen for its balance between rigidity under impact and manufacturing precision. Three distinct shell sizes across the XS-to-XXL range mean the EPS liner is sized appropriately for each head circumference, rather than relying on thick padding to compensate for a single oversized shell. The result is more predictable energy absorption and a helmet that sits correctly on the head from day one.
Visor System
The scratch-resistant polycarbonate visor is prepared for Pinlock MaxVision 70 inserts and is also tear-off compatible, giving riders the option to configure the helmet for track days or wet-weather road riding. The new Visor Lock mechanism prevents unwanted visor lift at motorway speeds, while the tool-free release system means visor swaps take moments rather than minutes.
Ventilation
Five large front air intakes channel airflow through optimised EPS air passages to four exhaust ports positioned beneath the rear spoiler. The circuit keeps fresh air moving across the head continuously, preventing heat build-up on longer runs or in stop-start urban traffic.
Liner and Comfort
The bi-elastic interior fabric wicks perspiration effectively and remains comfortable across a full day's riding. The liner is fully removable and machine washable, and the cheek pads can be swapped independently. A sculpted channel along the lower interior accommodates spectacle arms without pressure points, and pre-routed channels in the liner are ready for a universal intercom unit.
Closure
The toothed micrometric quick-release buckle fastens and releases cleanly with gloves on — a detail that matters most on cold mornings or after a long day in the saddle.
Fitment and Compatibility
The KYT TT-Revo Y6TR0051 is a universal full-face helmet approved for road use under ECE 22.06. It is particularly well suited to riders of 125 cc motorcycles, commuters and sport-touring riders seeking an entry-level helmet with genuine design credentials. Select your size using the head circumference guide below.
Size Guide
| Size | XS | S | M | L | XL | XXL |
|---|---|---|---|---|---|---|
| Head circumference (cm) | 53–54 | 55–56 | 57–58 | 59–60 | 61–62 | 63 |
If your measurement falls between two sizes, choose the larger of the two for initial fit — the liner will settle slightly with use.
