At a glance: Drivers and owners of motorcycles and quads know this one as the Varta YTX9-BS. Terminal position is the detail people most often forget.
Varta YTX9-BS: what it is and who it suits
Sized for the tight battery boxes of motorcycles and quads: that is the Varta YTX9-BS. The box measures 152 × 88 × 106 mm, and a few millimetres decide whether the seat closes. Typing the brand and code beats scrolling through dozens of lookalike boxes.
Nothing unusual about 8Ah: a standard capacity for motorcycles and quads. 135A beats many larger batteries for cranking.

Practical advice for motorcycles and quads
Couriers on scooters start and stop all day long. Photograph the cable routing before removing the old battery, especially where leads run under the frame. Small bike batteries often last only a few seasons.
