The CSC RX3 swingarm. The square tube is formed to accept the rear axle mounting hardware.

NOTE: The new 2019 CSC RX4 is built on an entirely new frame that accommodates the new NC450 450cc single-cylinder motor. Please see CSCmotorcycles.com for a complete list of specifications and comparisons between the two models
