In combination with a motorcycle motor housing and a drive chain, a device to protect the motor housing from wear by the chain, comprising

• a plate member upwardly bent at its longitudinally rearward end, and a wear resistant member attached along the bottom of said plate member,
• an ear upstanding from a side edge portion of said plate member,
