The KTM SX 380 is a benchmark motocross bike from the '90s, built to withstand the most extreme off-road stresses. Original discs, after dozens of track or enduro sessions, accumulate micro-fractures and lose braking power precisely when you need it most: in emergency stops before fast corners.
The Brembo Serie Oro brake discs for your SX 380 include the front kit 68B407B8 with 260mm diameter and 3.5mm thickness, and the rear kit 68B40752 with 220mm diameter and 4mm thickness. Each disc is specifically designed for the thermal and dynamic demands of your bike.
The forged aluminium bell reduces unsprung weight at the front, improving steering responsiveness and ground impact absorption. The peripheral drilling evacuates heat and friction gases outward, maintaining stable temperatures even during consecutive braking typical of motocross. Pairing with Brembo pads ensures immediate and progressive bite.
All discs are TÜV approved for European road type approval and represent a direct OEM replacement: drop-in fitting without frame modifications, no brake system overhaul needed, no extraordinary maintenance. Full compatibility with your SX 380 original calipers.
2-year warranty, products 100% Made in Italy by Brembo. Trust M4Tuning.com for your KTM: guaranteed stock, fast delivery, specialized technical support.
