TECHNOLOGY TYPE: AGM Sealed Factory Activated (AGM version of the classic YB9 flooded)
IMPORTANT: Yuasa does NOT manufacture a YB9-BS AGM; most mechanics still fit the classic YB9-B flooded (with caps and acid). This OUTDO YB9-BS(MF) offers the SAME dimensions + capacity but in a sealed, maintenance-free AGM format. It is an ideal UPGRADE whilst retaining the original form factor.

Customer Questions & Answers
What are the exact dimensions and weight of the Kage AGM YB9-B battery? Is this size standard for 125cc motorcycles?
The Kage AGM YB9-B measures 135 mm (L) x 75 mm (W) x 139 mm (H), and weighs 3 kg. This format is common for motorcycles from 50cc to 250cc, especially 125cc models, but it is important to check the measurements and capacity of your motorcycle’s original battery before buying.
Can this battery be installed directly without adding acid? Is any special procedure needed before first use?
This battery comes sealed and already has the gel electrolyte installed. There is no need to add acid or carry out any special initial charging procedure. Simply install it, making sure to connect the positive and negative terminals correctly (positive on the left, front view), and secure it firmly in the compartment.
What maintenance does this type of AGM gel battery require and what is its estimated lifespan under moderate use?
AGM gel batteries require very little maintenance: they only need to be kept clean, dry and with the terminals free from corrosion. There is no need to top them up with water or check the electrolyte level. Typical lifespan under moderate use (partial discharges, proper storage) can be around 400–500 cycles, equivalent to 3–5 years, although this varies depending on usage and storage habits.
What are the advantages of a YB9-B motorcycle gel battery compared with a lead-acid battery?
The YB9-B motorcycle gel battery uses gel technology that offers lower energy loss when not in use, better power delivery at start-up, and a longer service life compared with traditional lead-acid batteries.
Which motorcycle models is this battery compatible with?
It is compatible with a wide range of motorcycles from brands such as Aprilia, Cagiva, Daelim, Derbi, Gilera, Harley Davidson, Honda, Kawasaki, KTM, Piaggio/Vespa, Suzuki, Triumph, Yamaha, among others that use compatible references such as YB9-B, HVT-9, YB9L-B, 12N7-4B, and more.
What is the voltage and capacity of this battery?
This battery has a voltage of 12V and a capacity of 9Ah, ideal for motorcycles that require strong starting power.
Is it available for immediate dispatch?
Currently this product is not available in stock and is not shipped to the Balearic Islands or by DHL Express.
