<![CDATA[Abstract: Indonesia’s motorcycle industry has experienced rapid growth, yet consumer participation in after-sales services such as periodic maintenance remains low. This study aims to analyze the influence of promotion and Customer Relationship Management (CRM) on consumer decisions to engage in periodic maintenance, with service interest as a mediating variable. The research was conducted using a quantitative approach with a sample of 100 consumers from AHASS Wahana Honda Jatake, Tangerang. Data were analyzed using the Structural Equation Modeling–Partial Least Squares (SEM-PLS) method. Results show that promotion and CRM have no significant direct effect on consumer decisions, but both have a significant positive effect on service interest. Service interest was found to fully mediate the relationship between promotion and CRM on consumer decisions. These findings highlight the importance of fostering service interest as a strategic link between marketing efforts and customer loyalty in official motorcycle service centers.
