Foremost has introduced updates to its motorcycle insurance program in California, combining a rate increase with revisions to its rule and rating structure. The filing, submitted on March 31, 2026, is scheduled to take effect August 1, 2026 for both new and renewal business.

At the headline level, the insurer is requesting a 3.3% overall rate increase, below an indicated need of 4.2%. The program covers 1,914 policyholders and approximately $1.03 million in written premium, translating to an estimated premium impact of about $34,000.

Separately, broader class plan materials tied to the program point to a larger underlying book, with 52,776 policyholders and $38.3 million in written premium, and a 17.2% overall rate impact in that context, highlighting differences in scope across filings .

The latest change follows a prior 14% increase that took effect in May 2025, suggesting continued pressure on the book, albeit at a more moderate level in this filing.

Beyond pricing, the update introduces refinements to premium calculation rules, reinstatement provisions, and classification definitions, alongside changes to rating variables such as vehicle value bands, usage assumptions, and operator characteristics. The rating framework remains highly factor-driven, incorporating mileage, driving record, years of experience, vehicle type, and territorial segmentation.

The filing also maintains wide dispersion at the policy level, with increases exceeding 500% and decreases of up to 76%, reflecting segmentation changes rather than uniform pricing adjustments.

Bottom Line: Foremost is pairing a modest rate increase on a smaller program segment with broader structural changes to its motorcycle rating plan, signaling continued recalibration of risk segmentation across its California book.
