Product rating: 5/5 (1x)

Your rating:

Premium BC Racing chassis with external magazine of the ER series with separate adjustment of compression and rebound damping. This extension allows the end user to individually adjust and adjust the amount of damping and preload. External ER series containers allow BC to increase the oil capacity in the damper. The additional oil capacity reduces the maximum oil temperatures, which reduces changes in damping ratios due to changes in oil viscosity. Reducing fluctuations in damping differences improves handling and achieves maximum performance on the road and track.

Choose a version and make a note.


Basic stiffness of front springs: 10kg / mm.
Basic stiffness of rear springs: 12kg / mm

Each shock absorber has the option of 30 stiffness settings, so the chassis can be tuned to the individual requirements of the rider. The RM series uses a MONOTUBE type silencer.

- rear upper bearing: aluminum bearing (uniball)
