Honda LFC2 specs: 2.0L (121.6 ci) 4-cylinder, 81 x 96.7 mm (3.1890 x 3.8071 in) bore and stroke, 13.9:1 compression. Rated 200 hp, 2025–2026.
The Honda LFC2 is undersquare — the 3.8071" stroke exceeds the 3.189" bore by 16.2% — a layout that trades peak RPM for leverage and torque low in the range. The 3.8071" stroke puts mean piston speed at 4,000 ft/min around 6,300 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 30.4 ci (498 cc).
13.9:1 is high for a production gasoline engine; running a ratio like that on pump fuel depends on chamber design and fuel delivery rather than the number alone.
It is one of 3 engines in the LF Hybrid family, all of them 121.6 ci — the differences between them are in compression, heads and rating, not displacement. 2 factory variants share these dimensions, rated at 200 hp across 2025–2026.

Factory specification sheet.
| Bore/stroke character | 0.838 — undersquare — stroke exceeds bore, which favours low-end torque |
|---|---|
| Mean piston speed at 6,000 RPM | 3,807 ft/min — in the range typical of performance street engines |
| Displacement per cylinder | 30.4 ci |
| Static compression | 13.9:1 — high enough that pump premium or better is normally required |
