The LS2 FF805 Thunder GP Aero is a full-face sport helmet with a 6K carbon shell, gloss clearcoat over the weave and no graphics. LS2 claims 1,280 g (±50) and ECE 22.06 approval, and a Pinlock lens comes in the box. It is the entry point into this carbon shell: the higher tiers of the line add paint, a photochromic visor or, on the Thunder GP PRO, a different helmet with a 9K carbon shell, three shell sizes, X-Static liner and FIM homologation. Riders who want a light carbon race-style helmet without paying for replica graphics are the target; the trade-off is one shell size for XS to XXL, so fit depends on padding rather than shell volume.

Rated 4.8 out of 5 across 289 ratings. Owners rate the finish and the weight highly and see it as a lot of carbon helmet for the outlay. Fit across the single shell range is the main point of debate.
The LS2 FF805 Thunder GP Aero in Gloss Carbon has a shell made of 100 percent 6K carbon. A clear gloss coat sits directly over the weave, with no graphics. In daylight the twill pattern shifts as you turn and looks dark anthracite. In shade it looks almost black.
The shell is molded as a single outer shell for all sizes, XS to XXL. The padding makes the difference between sizes. The helmet weighs 1,280 grams, plus or minus 50. It meets ECE 22.06 and has a double D-ring closure and cheek pads with an emergency release.
Vents are at the chin, forehead and crown, with channels in the EPS and an outlet under the rear spoiler. The wide Class A visor changes quickly and has tear-off mounts. A Pinlock 120XLT MaxVision insert is included. The helmet has no sun visor.
