Yuasa YTZ14S Motorcycle AGM Battery YUAM72Z14 — 230 CCA, 11.2 Ah, Factory-Activated

The Yuasa YUAM72Z14 YTZ14S is a factory-activated, high-performance AGM motorcycle battery engineered for strong cold starts, vibration resistance, and maintenance-free service.

Built with Yuasa’s expanded plate grid and enhanced active materials, the YUAM72Z14 (YTZ14S) delivers extra starting power and long life in compact dimensions. The battery ships factory-filled, sealed, and charged, using Absorbed Glass Mat (AGM) construction to trap electrolyte and prevent spills while minimizing water loss. With a 230 CCA rating and 11.2 Ah capacity, this valve-regulated lead-acid unit is suitable as a primary or auxiliary battery in many modern motorcycles and scooters that demand reliable starting performance and resistance to heavy vibration.

How does this battery improve starting and reliability?

The YTZ14S uses an expanded plate grid with more plates to increase surface area for faster current delivery at start-up. Enhanced active materials and AGM separators reduce internal movement and help the battery withstand vibration common to motorcycles. These design choices combine to give stronger, more consistent starts and longer service life compared with conventional lead-acid cells.

• 230 CCA at 0 °F (-18 °C) for dependable cold starts
• 11.2 Ah capacity measured at 10-hour rate for reserve power
• AGM/VRLA construction prevents spills and minimizes maintenance
• Expanded radial plate grid increases starting amps and durability

What are the physical size and installation details?

The YUAM72Z14 is compact and designed to replace many common YTZ14S-form batteries in motorcycles and scooters. It measures 150 mm long, 87 mm wide, and 110 mm tall, and weighs about 8.6 pounds (with electrolyte). Because it arrives filled and charged from the factory, it’s ready to install straight away.

• Dimensions: 150 × 87 × 110 mm (L × W × H)
• Weight with acid: 8.6 lbs (approx.) for correct handling and fit
• Factory-activated — filled, sealed and charged at the factory
• Valve-regulated design eliminates refilling

Which bikes and scooters is it compatible with?

This Yuasa YTZ14S fits a wide range of motorcycles and some scooters as either the primary or auxiliary battery. It’s listed for many BMW, Honda, KTM, Suzuki, Triumph, Yamaha and other models spanning sport bikes, touring machines, and adventure bikes. Always confirm dimensions and terminal orientation match your vehicle’s requirements before purchasing.

• Fits multiple BMW R1200GS/R1200GS Adventure and F-series models
• Compatible with Honda CB1100, Africa Twin, VFR models, and others
• Used in KTM Adventure/Super Duke families and several Suzuki, Yamaha, Triumph models
• Also applicable to scooters like the BMW C600 and Suzuki Burgman AN400

How does maintenance and longevity compare to regular batteries?

The AGM construction and lead-calcium improvements extend life versus conventional flooded batteries and reduce service needs. The valve-regulated, nonspillable design means you won’t need to add water, and the factory activation process ensures correct initial charging and conditioning. With proper charging practices, you can expect significantly longer usable life under typical motorcycle conditions.

• Maintenance-free — no watering required
• Up to three times longer life than many conventional batteries under similar use
• Spill-proof VRLA reduces risk during handling and installation
• Charge current guidance: Regular charge current approx. 1.1 A

Who is this for? The Yuasa YUAM72Z14 YTZ14S is aimed at riders who need a compact, high-cranking-power battery that tolerates vibration and requires minimal upkeep. It’s a strong choice for sport, touring, and adventure motorcycles, as well as select scooters and auxiliary battery applications where reliable starts and long service life are priorities.
