The Kawasaki J 300 is a maxi scooter that dominates the road with sporty performance and superior comfort, but its substantial weight demands a braking system equal to the most critical situations. Brembo Serie Oro brake discs transform braking with technology proven on competition motorcycles, guaranteeing progressivity and reliability in every riding condition.
The front kit 78B40819 (260mm, 4mm thickness) and rear kit 68B407K4 (240mm, 5mm thickness) were developed specifically for the J 300. Each disc is forged with millimeter precision and subjected to rigorous quality controls to ensure stable performance over time, both in the city and on the highway.
The aluminium bell reduces unsprung weight by over 20% compared to traditional steel, improving suspension reactivity and the overall response of the scooter. The symmetric drilling guarantees optimal heat and friction gas evacuation, preventing fade even after consecutive intense braking, essential on a scooter of this displacement.
TÜV type approval and ABE certification ensure complete European regulatory compatibility without any registration modification. Installation is completely plug-and-play: no modifications, no adaptations, just direct replacement of OEM original discs. The Brembo Serie Oro technology significantly improves initial pad bite and braking modulation at any temperature.
2-year warranty and 100% Made in Italy certify Brembo's craft excellence. On M4Tuning.com you'll find the complete kit with dedicated technical support and fast shipping to transform your J 300's braking with the quality of the world's best track motorcycles.
