Brake Caliper Adapter Stage6 4-piston AM6 / Derbi

Stage6 Brake Caliper Adapter for 4-Piston Caliper - 50cc Geared bikes

Stage6 brake caliper adapter for 4-piston calipers for 50cc geared mopeds with standard fork such as Rieju MRT, Sherco 50, Beta RR, and many others.

The adapter is made from CNC-machined aluminum, offers high rigidity, and ensures secure mounting even during heavy braking. It is suitable for sporty use or racing applications.

Installing the Stage6 Adapter

• Rieju MRT (standard fork): Plug & play installation without washers.
• Sherco 50 & Peugeot XP6 (2026) (standard fork): Use the 2 included washers.
• Beta 50 RR: Keep the original washers and additionally use 2 washers MF60.16634 (not included).

Stage6 also offers a flexible solution: in stock configuration, the adapter is installed without spacers with a 260 mm brake disc. For setups with a 300 mm oversize brake disc, simply use the 2 included 40 mm spacers.

With this adapter, you can significantly increase the braking performance of your moped without complex modifications, while taking full advantage of a radial brake caliper. For a consistent and high-performance setup, we recommend combining it with a Stage6 R/T 4-piston brake caliper.
