The S-R7 Breath Deflector is an S-R7-specific motorcycle helmet accessory and replacement component designed for racing and sport riders who want to maintain the helmet’s intended internal setup and clearer vision on track.
Constructed from durable TPU with a compact, low-profile design, it helps channel breath away from the visor to reduce fogging and support lasting comfort and focus in demanding riding conditions.
