Yuasa SY50-N18L-AT Yumicron 12-Volt Battery

Power up your heavy-displacement touring bike, high-capacity snowmobile, or heavy-duty quad with the exceptional cranking force of the Yuasa SY50-N18L-AT Yumicron 12-Volt Battery. Engine-engineered specifically for large-bore powersports engines, the Yumicron series features extra lead plates packed into every cell to deliver up to 30 percent more cranking power than standard conventional batteries. Whether you are prepping for a cross-country highway tour or firing up your engine on a freezing winter morning, this high-output power cell supplies the immediate, punchy ignition required to turn over high-compression pistons with total confidence. Built with a rugged, high-impact polypropylene container and heavy-duty internal separators, the SY50-N18L-AT absorbs severe engine vibration, frame shock, and rough trail feedback to protect delicate internal components. Its specialized radial grid architecture maximizes electrical conductivity while minimizing internal resistance for swift energy transfer. Featuring translucent casing walls for fast visual fluid inspections, this heavy-duty 12V battery brings the perfect balance of classic compatibility, high-reserve capacity, and proven Yuasa reliability to your ride.

• Special thin separators allow two extra plates per cell to be installed, for a 30 percent improvement in cranking performance
• Engineered to protect against corrosion, withstand vibration, and deliver high cranking power

The Yuasa SY50-N18L-AT Yumicron 12-Volt Battery delivers dependable starting power for large-displacement touring motorcycles, snowmobiles, and heavy-duty ATVs. Designed for high-compression powersports engines, this conventional battery uses additional lead plates in each cell to provide up to 30 percent more cranking performance than standard designs. It supplies the strong, immediate ignition power needed for reliable starts during long rides, demanding trail use, and cold-weather operation.
Built with a high-impact polypropylene container and heavy-duty internal separators, the Yuasa SY50-N18L-AT is engineered to withstand vibration, frame shock, and rough riding conditions. Its radial grid construction promotes efficient electrical conductivity while reducing internal resistance for fast energy transfer. Translucent casing walls make it easier to monitor electrolyte levels during routine maintenance, while the conventional design provides broad compatibility with select older powersports applications.
The Yumicron battery combines durable construction, strong reserve capability, and proven Yuasa Battery reliability for riders who require consistent starting performance. It fits applications including the 1986-1988 Suzuki GV1400 Cavalcade, 1982 Yamaha XJ1100 Maxim, and 1986-1991 Yamaha XVZ1300 Venture Royale. Verify the vehicle application and battery specifications before installation.
