Alpha Racing Additional Weight Set

The alpha Racing additional weight kit reliably brings race bikes up to the required minimum weight. An base plate and five solid stainless steel weight plates allow ballast from 1,592 g to 4,135 g in six stages. The set replaces the previous additional weight box.

When is ballast required?
Many racing series specify a minimum weight for the motorcycle, or for motorcycle and rider combined. Light riders or consistently weight-reduced builds quickly fall below this value. The missing difference must then be added as ballast, firmly mounted to the motorcycle. Some series additionally link ballast to rider weight.

Mounting position and attachment
The set mounts to the lower end of the main frame, centrally towards the rear wheel. This places the ballast low and central in the motorcycle, in line with common racing practice of positioning additional weight as low and as close to the centre of the bike as possible. The base plate is attached to the frame via vibration-damping mounts.

Securing the ballast
The weight plates feature holes for safety wiring. The final weight plate has an additional hole to hold a locking plate for the nut. This allows the ballast to be secured reliably. Locking plates are included, safety wire is available separately as an accessory in our shop.

Modular design
The base plate stays permanently mounted to the frame. Depending on the required ballast, up to five weight plates of 495 g each are added. This allows the payload to be adapted to rider, racing series and regulations without changing the system.

Weight stages:
Base plate incl. mounting material: 1.59 kg
each additional weight plate (max. 5): +500 g

From the first weight plate onwards, additional mounting material is used, so the first stage is slightly larger than the following ones.
