BRAKING S3 BATFLY FRONT BRAKE DISC YAMAHA YZ 250 F 2010-2013

Braking S3 Batfly brake disc made of steel with black anodized hub.

The track-hub-disc connection is left free in three points to allow thermal expansion while limiting the braking wheel effect. The alternating BATFLY grooves on the two surfaces of the disc create an auto ventilation mechanism that allows better cooling of the disc. Mud and dirt are also easily removed from the braking surface.

The external and internal diameter of the disc have a non-round design that allows a better radial expansion of the disc in extreme heat conditions.

Technical features:

External diameter: 270 mm
Internal diameter: 118 mm
Thickness: 3.20 mm
Number of holes: 6
Hole circumference: 134 mm
