Verified Customer Reviews for HJC i31
Draughty and noisey.
27 March 2025 by Anonymous
Having had the earlier JVC open face helmet, I found this one draughtier and noisier. The ratchet mechanism for the visor is very good but noisy in operation when you have the helmet on. The tinted integral visor doesn’t come down far enough and the bottom edge breaks through my line of vision. Not a fan of the clasp, although it works well.
All in all for the money not too bad.
As always the delivery was exceptional.
