| J-Series 350 models | Not compatible unless EPC confirms | Meteor, Reborn Classic, Hunter and new Bullet use a different platform. |
| Himalayan / Scram / 450 / 650 models | Not compatible unless EPC confirms | Different final-drive dimensions and part families. |

Important: 597275 should be ordered only where the old Bullet 350 / Electra 4S-5S parts catalogue, old packet, service estimate or EPC confirms 597275.
