Yuasa Motorbike battery YTX16-BS / YTX16 12V 14Ah (14.7Ah) (AGM maintenance-free)

The Yuasa YTX16-BS (often also referred to as YTX16 when factory-filled) is a high-performance AGM battery specially developed for motorcycles with increased energy requirements. It shares its footprint with the widely used 12 and 14 models, but makes maximum use of the available height in the battery box to accommodate more lead plates and acid volume. With a capacity of 14 Ah (10h) or 14.7 Ah (20h) and a cold start current of 230 A (EN), it offers significantly more reserves for large-displacement cruisers and touring machines.

Highlights at a glance

• Maximum capacity in a small area: Uses the standard footprint (150 x 87 mm), but at 161 mm is significantly higher than a YTX14. This results in almost 15 Ah capacity for long service life and plenty of accessories.
• AGM technology: The acid is bound in glass fleece (Absorbent Glass Mat), making the battery leak-proof, vibration-resistant and cycle-resistant – ideal for heavy V2 cruisers.
• Strong starting power: With 230 A cold start current, it reliably turns over even large engines (like 1500 or 1600 V-Twins).
• Maintenance-free: Thanks to VRLA technology (valve regulated), the system is hermetically sealed after initial filling; topping up water is neither possible nor necessary.
• The "high-rise" format: Specially designed for battery boxes that are deep but allow little width (e.g. Kawasaki VN 1500/1600, Suzuki Marauder 1600).
• Long service life: The robust construction and larger amount of acid provide better thermal stability and durability compared to smaller batteries.

The powerhouse for heavy cruisers

The YTX16-BS is the standard battery for many "big bikes", especially from the chopper and cruiser segment. It is indispensable for models such as the Kawasaki VN 1500 / 1600 Mean Streak, the Suzuki VZ 1600 Marauder or even some Triumph Tiger 800 models (depending on year/equipment). It provides enough buffer to keep the voltage stable even with a lot of chrome accessories (auxiliary headlights, sound systems).

FAQs about the Yuasa YTX16-BS

What is the difference to the YTX14-BS?

Both batteries have the same length (150 mm) and width (87 mm). The difference is the height.

• YTX14-BS: 145 mm high (12 Ah).
• YTX16-BS: 161 mm high (14 Ah). The YTX16 is 1.6 cm higher. It only fits in vehicles that have this extra space at the top. Theoretically it can be used as an upgrade for the YTX14 if the seat can then still close.

What is the difference to the YTX20-BS?

The YTX20-BS is a completely different size class.

• YTX16-BS: 150 mm long.
• YTX20-BS: 175 mm long. The 20 battery is much longer and will not fit in the 16 holder.

Is there a YTX16-BS-1?

Yes, the suffix "-1" at Yuasa often indicates a different pole arrangement or terminal type. With the YTX16-BS-1 the pole arrangement is usually identical (positive left), but to be sure always check the pictures of the terminals and the position of positive/negative on your old battery before ordering.

Do I need to be aware of anything with the BS version?

Yes, with the "Bottle Supplied" version you have to fill in the acid yourself. Important: After filling, leave the battery open for approx. 1 hour ("outgassing") before pressing on the sealing strip. Then charge it fully with a motorcycle charger. Once sealed, it must never be opened again.
