S3 BATFLY front disc features the non round profile; unique semi floating design where the outer track is connected to the inner carrier in 3 spots, yet separated by rivet pins in 3 areas. COULD BE OVERSIZE DEPENDING ON APPLICATION.
Offers a more fixed, rigid brake feeling but yet with the heat dissipation capability of a floating disc thanks to the 3 rivet system.
This gives the best compromise between prompt brake response of a fixed disc but with the performance & improved cooling typical of floating discs.
Used by top off road & motocross teams & riders worldwide.
