Fim — Katalog Piston

During race events, FIM technical scrutineers reference the catalog to:

Any deviation leads to penalty – from grid demotion to disqualification, as in the 2022 case where a WorldSBK team used uncatalogued pistons with a modified crown profile.

FIM is an aftermarket spare part manufacturer specializing in high-quality pistons, piston rings, pins, and clips. Unlike OEM (Original Equipment Manufacturer) parts, FIM focuses on providing durable and often performance-oriented alternatives at a competitive price point. They are particularly famous for their oversize pistons used in cylinder reboring—a common practice in Southeast Asian workshops.

These are heavy-duty cast pistons with anti-friction coating. katalog piston fim

FIM pistons are often categorized by "FIM codes" (e.g., FIM 4, FIM 80) which correspond to specific engine types and pin diameters. Any deviation leads to penalty – from grid

Standard pistons are rarely used in rebuilds because cylinder bores wear out. The catalog provides:

The FIM catalog specifies Class A, B, or C wrist pins. A loose pin causes a "clattering" noise (piston slap). A tight pin seizes the small end bearing. FIM pistons come with color-coded pins for precise fit.
