Honda Acty HA3/HA4 — Full Measurements

Chris Palmer · Pricing & Landed-Cost Analyst Published June 23, 2026

Data verification status: Cross-checked against JDM-aligned sources; some figures flagged below pending final manufacturer confirmation — last reviewed 2026-06-23.

Every figure on this page is checked against the kei regulatory caps (3,400 mm length / 1,480 mm width / 350 kg payload) before publishing — export-market variants of this name routinely exceed those caps and are not the truck you're importing. Where two reputable sources disagreed, or only one source could be found, that's flagged in the note rather than presented as settled.

Exterior

Spec	Metric	Imperial
Overall length	3,395 mm	133.7 in
Overall width	1,475 mm	58.1 in
Overall height	1,735 mm	68.3 in
Wheelbase	1,900 mm	74.8 in
Track, front	1,295 mm	51.0 in
Track, rear	1,310 mm	51.6 in
Ground clearance	185 mm	7.3 in
Minimum turning radius	3.6 m	11 ft 9.7 in
Approach angle	Not yet confirmed	—

⚠ Overall height: 2WD (HA3): 1,735 mm. 4WD (HA4): 1,745 mm. Both figures confirmed via the Honda JP official spec PDF — do not state a single height without specifying drivetrain.
⚠ Minimum turning radius: Manufacturer-stated minimum turning radius: 3.6 m (2WD/HA3), 3.7 m (4WD/HA4), per the Honda JP spec PDF. Some importer listings show 4.5–4.7 m — these appear to be listing errors or a different measurement method; use the Honda JP figures.

Cargo bed

Spec	Metric	Imperial
Bed length	1,940 mm	76.4 in
Bed width	1,410 mm	55.5 in
Bed height (side rail)	290 mm	11.4 in

Weight & capacity

Spec	Metric	Imperial
Curb weight	770 kg	1,698 lb
Payload (regulatory max)	350 kg	772 lb

⚠ Curb weight: 770 kg for 2WD (HA3) standard grade, 820 kg for 4WD (HA4) standard grade, per the Honda JP spec PDF. The Attack grade (with diff-lock and UL crawler gear) runs heavier at approximately 830 kg. Use a 770–830 kg range and check the specific trim before citing an exact figure.

Wheels & tyres

Spec	Metric	Imperial
Stock tyre size	145R12 6PR LT	—
Bolt pattern (PCD)	4×100mm	—

⚠ Stock tyre size: Confirmed via the Honda JP official spec PDF.
⚠ Bolt pattern (PCD): Confirmed across multiple aftermarket wheel-fitment sources. Cross-check against a JDM wheel fitment database before relying on this for a wheel purchase.

Fuel

Spec	Metric	Imperial
Fuel tank capacity	37 L	9.8 gal

⚠ Fuel tank capacity: Approx. — the Honda JP spec PDF states 37 L for final production; some importer sources show a 35–38 L range, likely reflecting early-vs-late build variation. Verify against the specific build year before treating as exact.

Towing

Kei trucks are not designed or rated for braked trailer towing the way a full-size truck is. See our towing use-case guide before assuming this truck can pull a loaded trailer. See our towing use-case guide for the full picture.

Context notes

The HA3/HA4 uses the carburetted E07A engine. Physically, the truck is dimensionally identical to the later HA6/HA7 — the upgrade to fuel injection with the HA6 did not change the body. If you're comparing bed size or turning radius between generations, the numbers are the same.
Weight distribution on the Acty is rearward — approximately 45/55 front/rear unladen, shifting further rearward when loaded. This is a direct consequence of the mid-engine layout and is actually an advantage for rear-wheel traction, not a downside.
Mid-engine layout and the cargo bed. The Acty mounts its engine transversely under the cargo bed rather than under the hood — a layout Honda maintained across every generation of the Acty truck. This raises the bed floor slightly compared to front-engine competitors and means the engine is accessed by lifting the bed. On the practical side: inspect the underside of the bed floor on any used Acty for heat discolouration or oil staining before purchase, as these are common signs of a poorly maintained engine. See our Honda Acty buyer's guide for the full pre-purchase checklist.
