What 12v 10ah Battery Replaces Honda Motosport Battery gtx1

The Honda Motosport GTX1 battery is a branded designation for a 12V 10Ah sealed lead-acid unit. The direct replacement is the YTX12-BS format, which shares identical specs: 150mm x 87mm x 130mm dimensions and a minimum of 180 cold cranking amps (CCA). 

According to Yuasa Battery’s official cross-reference guide✔[1] (2024), the YTX12-BS is the OEM-equivalent for over 47 Honda powersports applications.

The 12V 10Ah Honda Motosport GTX1 battery replacement refers to the YTX12-BS a sealed AGM battery matching the GTX1’s voltage, capacity, physical dimensions, and terminal layout. The GTX1 is a private-label code. The YTX12-BS is the universal industry equivalent.

What “GTX1” Actually Means: And Why It Confuses People

The GTX1 code isn’t a universal battery industry standard. It’s a private-label designation used by Honda’s Motosport accessory line which is exactly why you can’t find a direct “GTX1” listing on most battery retailer sites.

Battery manufacturers use their own proprietary codes. GTX12-BS (Chrome Battery’s designation) and YTX12-BS (Yuasa’s designation) refer to the same physical battery spec. The prefix changes. The battery doesn’t.

Or maybe I should say it this way coding system is brand-specific, not spec-specific. Once you know the underlying spec (12V, 10Ah, YTX12-BS format), you’re shopping a competitive market instead of chasing a ghost SKU.

Confirmed Replacement Part Numbers: The Cross-Reference List

I’ve seen conflicting data on this some older forums list the YT12A-BS as an equivalent, but its dimensions differ by 8mm in height. My read is that the YTX12-BS is the correct cross-reference for the vast majority of Honda Motosport applications.

• Yuasa YTX12-BS — OEM standard, the safest pick
• Chrome Battery GTX12-BS — Direct private-label equivalent
• Mighty Max ML10-12 — Compatible spec, value-tier option

Quick note: “10Ah” is the capacity. It does NOT tell you the terminal polarity or the physical layout. Always verify those separately.

To find and install the correct Honda GTX1 replacement battery:

1. Note your current battery’s terminal layout positive terminal position, left or right.
2. Confirm dimensions: 150mm (L) × 87mm (W) × 130mm (H).
3. Order a YTX12-BS from Yuasa, Chrome Battery, or Mighty Max.
4. Charge before install — AGM batteries ship at roughly 75–80% capacity.
5. Reconnect the negative terminal last.

The physical dimensions of the Honda Motosport GTX1 battery are 150mm × 87mm × 130mm (approximately 5.9″ × 3.4″ × 5.1″). According to Yuasa’s 2024 product catalog✔[2], the YTX12-BS matches these measurements exactly and fits the Honda battery tray without modification. Installing a battery even 5–8mm taller can prevent the seat or cover from closing fully.

The Two Specs Most Guides Don’t Mention

Terminal Polarity: The Silent Fitment Killer

Look if you’re buying a battery online and you’ve never checked terminal polarity, here’s what actually works: stand in front of the battery as it sits in the tray. If the positive (+) terminal is on the left, you need a “standard” layout. Most YTX12-BS batteries are standard, but verify before checkout.

Reversed polarity on a 12V powersports battery won’t just cause a fitment problem. It can damage your Honda’s electrical system immediately upon connection.

Cold Cranking Amps (CCA): Don’t Go Lower

The GTX1 battery delivers 180 CCA minimum. This matters most in cold climates a lower-CCA battery cranks sluggishly below 50°F and may not start at all below freezing.

Some experts argue that a higher CCA battery (200+ CCA) is always better. That’s valid for year-round riders in northern climates. But if you’re in a temperate zone and weight is a concern, 180 CCA is the correct minimum not a floor to exceed at all costs.

Top 12V 10Ah GTX1 Replacements

YTX12-BS vs GTX12-BS: The YTX12-BS (Yuasa) is better suited for riders prioritizing OEM-level reliability because it is the original equipment standard for Honda powersports. The GTX12-BS works better when cost is the primary factor. The key difference is brand naming the core specifications are identical.

What Most Battery Replacement Articles Get Wrong

First, they list compatible batteries without telling you to verify the terminal position on YOUR specific Honda before ordering. The YTX12-BS comes in different terminal configurations depending on the manufacturer run.

Second, they skip the “dead on arrival” issue entirely. According to the 2024 Powersports Battery Market Analysis✔[3], AGM batteries now account for 42% of powersports replacements but buyers frequently report receiving a battery that simply needs a 4–6 hour initial charge before it performs. Plug it into a smart AGM charger before you condemn it.

What most guides skip: the GTX1’s electrolyte is factory-sealed. You cannot add water, check cells, or recondition it like an older flooded lead-acid battery. Once it fails a load test, it’s done.

Sealed AGM powersports batteries cannot be reconditioned or refilled. A battery that won’t hold charge after a full 6-hour AGM charge cycle, or one that is 3–4+ years old, should be replaced and not recharged repeatedly. Users who’ve tried trickle-charging a failed GTX1 often report temporary voltage recovery with no real cranking power restored. Load testing is the only reliable diagnostic.
