The HARDDRIVE Oil Filler Cap features a non‑liquid filled oil temperature gauge that accurately displays temperatures from 50 °F to 350 °F. This range covers the typical operating envelope for most off‑road and street‑legal motorcycles, allowing riders to monitor engine conditions without the need for additional fluid reservoirs.
Finished in a polished chrome finish, the cap provides a subtle yet effective customization option for any bike. Its sleek appearance complements a wide variety of motorcycle styles while maintaining the functional integrity required for reliable oil system operation.
