Very good point, weight no doubt is a factor for both safety and comfort. In comparing the ARAI models that were tested with the six "other" helmets that received a higher 5-star safety rating and a "very good" rating in the high speed impact tests, only one helmet appeared to be clearly lighter, the BELL MR4 CARBON. And the good news is, its price point is about the same as Arai and should thus carry the same bragging rights. :-O

ARAI:
Astro 1.40 kg.
Chaser 1.50
Condor 1.55
Quantum 1.50
RX7 1.60
Corsair 1.35
Viper 1.40

BELL:
M4R 1.35
M4R CARBON 1.20
M5X 1.40

HJC HQ1 1.50

NITRO AKIDO 1.50

SHARK RSX 1.60 8)
Where do you get your stats? None of the above mentioned Arai helmets are current model year. I think 3 of those are over 4 years old. Most of those are Euro spec lids anyway.
