Accossato DKS263N Floating Wave Front Brake Disc – 330 MM

Description

The Accossato DKS263N is a front oversized (330 mm) floating wave brake disc specifically designed for Harley-Davidson Softail and Touring motorcycles.

Compared to the original 300 mm disc, the increased 330 mm outer diameter provides greater braking leverage:
you get more braking force with the same lever pressure, resulting in shorter stopping distances, stronger initial bite, and better control during hard braking.

The floating structure allows the rotor band to move slightly relative to the carrier, ensuring optimal contact between the disc and pads even under heavy thermal stress. This improves braking consistency, reduces the risk of warping, and enhances overall safety.

The wave profile further contributes to weight reduction and heat dissipation, while also giving your Harley a more aggressive, performance-oriented look.

Accossato also offers a 300 mm stock-diameter version (e.g. DKS262) for riders who prefer OEM size but still want the benefits of a floating disc.

Installation Notes

• Designed as an oversized front upgrade from the OEM 300 mm disc.

• Verify compatibility with your fork, caliper, and wheel before purchase.

• Oversized disc typically requires matching caliper spacers or a relocation bracket (not included unless specified in a kit).

• Use with quality brake pads and bleed the system properly after installation.

• Professional installation is recommended, especially on heavy touring motorcycles..
