| Honda's profilation of this bike |
| For 2021 the CRF400RX receives a wide array of improvements under a development theme of ‘The ultimate off-road weapon´. Firstly it is 2.3kg lighter thanks to a revised frame and subframe. The new frame and swingarm’s rigidity balance, combined with tighter chassis geometry, heightened ground clearance and suspension changes, are all targeted at creating optimal cornering performance. |
