Motorcycle battery Motobatt YTX12BS Quadflex 14Ah 200A 12V
The Motobatt YTX12BS motorcycle battery is rated at 12 V, 14 Ah and 200 A of cold cranking current (EN) from the Quadflex range, and is designed for motorcycles, scooters, quads and personal watercraft. Its 151 × 87 × 130 mm make it the exact replacement for the 14 Ah battery fitted as standard to many motorcycles.
- Compact and lightweight format.
- Holds its charge through winter storage.
- Sealed and ready to fit, no acid handling.
- AGM: faster recharging and better cycle resistance than a conventional battery.
What the Motobatt YTX12BS is for
The Motobatt YTX12BS is a common replacement in motorcycles, scooters, quads and personal watercraft. If your bike spends the winter standing, a trickle charger stops it reaching spring flat. Check that it matches your current battery in dimensions, terminals and hold-down: this reference has a weight of 4.40 kg.
Dimensions, polarity and mounting
It has external dimensions of 151 × 87 × 130 mm and weighs 4.40 kg. For a direct replacement, the current battery tray must accept these dimensions and the same terminal layout; otherwise adapters will be needed or the hold-down will change.
Why choose Motobatt batteries
Motobatt batteries stand out for capacity and cranking current above the original battery in the same tray, thanks to a compact AGM design and the four-terminal Quadflex system. We guarantee that every Motobatt arrives new, charged and with the manufacturer's full warranty.
The Motobatt YTX12BS: Quadflex range and AGM technology
Within the Motobatt catalogue, the Quadflex series groups the references designed for this use. The YTX12BS is the 14 Ah model of that family, with the same performance as its siblings in other sizes.
In an AGM battery the electrolyte is absorbed in glass-fibre separators: there is no free liquid, it cannot spill and it can be mounted at an angle. That construction lowers internal resistance, speeds up recharging and multiplies cycle life compared with a conventional battery.
Usage and maintenance tips
If the bike spends the winter standing, connect a trickle charger: deep discharge through inactivity is the first cause of premature failure. Check the resting voltage before the season (above 12.6 V on a charged battery) and make sure the terminals are clean and tight.
Official warranty
The Motobatt YTX12BS comes with the manufacturer's official warranty. The warranty does not cover discharge through prolonged inactivity: if the bike stands for months, use a trickle charger.
When you get it and how to return it
Order before 6:00 pm with stock available and it leaves today: mainland Spain and Portugal receive it in 24-48 working hours, the islands and the rest of the EU in 3 to 5 days. You have 14 days to return it if it has not been installed, with free collection on the mainland, and shipment tracking by email.

Frequently asked questions
How do I change this battery step by step?
In most motorcycles it fits in 15-30 minutes with a 10 mm wrench; if the battery is under the seat or in the boot the time can double. See the step-by-step guide on our blog. Quick summary: 1) switch off the engine and remove the key; 2) locate the original battery (engine bay, boot or under seat); 3) disconnect the negative (−) terminal first, then the positive (+); 4) loosen the hold-down clamp and remove the old battery; 5) fit the new one in the same orientation — match the polarity shown on the product sheet; 6) connect the positive (+) first, then the negative (−). On motorcycles with Start-Stop or BMS, register the battery via OBD so the alternator applies the correct charging profile.
What is the service life of the YB12BB2 model?
Expected lifespan of the Motobatt YB12BB2 is 4 to 7 years in regular use (depends on technology and climate). In cold regions it drops slightly due to cold-start stress; in very hot regions it also drops because of electrolyte evaporation. To extend its life: avoid deep discharges (headlights on with engine off), have the alternator checked yearly, and keep the battery clean and properly secured.
What size is this battery?
Dimensions (length × width × height) are 151×87×130 mm — also written as 151x87x130 mm — following the European DIN standard. Always measure the space in your motorcycle before buying: even one extra millimetre can prevent the hold-down clamp from closing. The height shown includes the terminals.
Will the Motobatt YB12BB2 battery fit my motorcycle?
Three options to confirm: 1) enter your number plate in the finder (DGT/DVLA/KBA auto-detect your model and engine); 2) check the "Compatible vehicles" tab on this page, where we list every vehicle verified by our technical team; 3) if you cannot find your model, message us on WhatsApp with brand, model, engine and year — we reply during business hours (Mon–Fri 10:00–13:30 and 16:40–18:00 (Spanish time, CET)). The YB12BB2 typically fits a wide range of European vehicles thanks to its standard DIN case format.
What are the equivalents of the YB12BB2 model?
Directly interchangeable batteries (same dimensions, same polarity, same Ah and CCA) are the OEM equivalents from leading brands: Bosch, Tudor, Exide and, depending on the model, Banner or Yuasa. Exact equivalence depends on technology — an EFB cannot be replaced with a conventional battery in Start-Stop motorcycles. See the "Equivalents" section to view recommended options at the same performance level.
