The 2001 Honda Foreman 400 typically uses a 12-volt sealed lead-acid battery, with the most common replacement being the YTX12-BS group size (roughly 11–12Ah). This size fits the original tray and provides reliable starting power under normal conditions.
The Foreman 400 is a mid‑size utility ATV, and choosing the right battery involves confirming fit in the tray, terminal orientation, and overall capacity. This guide outlines the standard size, alternatives, and how to verify compatibility before purchasing a replacement.
Common battery sizes for the Foreman 400
Below are the sizes most often used as replacements for the 2001 Foreman 400. Always verify tray dimensions and terminals before buying.
- YTX12-BS — 12V, typically about 11–12Ah; the standard OEM/aftermarket replacement that fits many Foreman 400 models.
- YTX14-BS — 12V, around 12–14Ah; higher capacity and longer reserve power, but may be physically larger and not fit all trays.
- YTX9-BS — 12V, about 7–9Ah; smaller capacity that can be insufficient for starting in cold weather or with accessories, not commonly recommended for the stock Foreman 400.
When in doubt, start with the YTX12-BS as the default replacement and only move to a larger size if the larger battery fits the tray and cable routing without obstruction.
How to verify the right size for your bike
Use these steps to confirm you’re selecting a battery that will fit and perform well in your machine.
- Check the current battery label for the model group size (for example, YTX12-BS) and the dimensions printed on the case.
- Measure the battery tray space (length, width, and available height) to ensure the new battery will fit without interfering with the air intake, fenders, or wiring.
- Note the terminal orientation and post spacing; ensure the replacement’s positive and negative posts align with your cables and battery hold-down.
- Review the cold-cranking/CCA rating; if you ride in very cold conditions or use a lot of electrical accessories, you may prefer a battery with higher CCA within the same group size.
- Compare OEM part numbers if possible (from your current battery or service manual) to avoid a mismatch, especially when buying from aftermarket suppliers.
Following these checks helps ensure the new battery will fit properly and provide reliable starts in your Foreman 400.
OEM vs aftermarket considerations
Both OEM and reputable aftermarket batteries can meet the Foreman 400’s needs. OEM parts guarantee original specifications, while high-quality aftermarket options can offer comparable performance at a lower price.
Tips for choosing
- Prioritize a sealed, maintenance-free battery (BS designation) to minimize leakage and maintenance.
- Look for reputable brands such as Yuasa, Exide, or Motorrad/Motobatt that offer YTX12-BS equivalents.
- Ensure the warranty policy covers the replacement in case of premature failure.
Assess the available space, terminal layout, and battery capacity to select the best option for your riding environment and usage.
Where to buy and compatibility tips
You can source a replacement battery from OEM Honda parts dealers, ATV/UTV retailers, or reputable motorcycle/battery shops. Always confirm the exact group size (YTX12-BS is the common default) and verify fit against your model year and VIN if possible.
Summary
For the 2001 Honda Foreman 400, expect a 12-volt battery with the typical replacement size of YTX12-BS. Verify tray space, terminal orientation, and capacity before purchasing, and consider a higher-capacity option like YTX14-BS only if it fits the tray. Whether you choose OEM or a trusted aftermarket option, ensuring fit and proper electrical ratings will keep your Foreman starting reliably in all conditions.
