AMSOIL 10W-50 Metric Synthetic Motorcycle Oil<\/strong> is a premium-grade lubricant engineered specifically for motorcycle engines. It is the result of intensive research and development to deliver exceptional performance across all types of motorcycle riding. It is designed to support high-RPM engines and wet-clutch systems and can withstand the extreme pressure placed on motorcycle transmissions.<\/p>\n

This oil has been proven to outperform conventional oils<\/strong> as well as other synthetic motorcycle engine oils available on the market.<\/p>\n

\n

Key Benefits<\/strong><\/h2>\n

1. Reduces Friction, Heat, and Wear<\/strong><\/h3>\n

AMSOIL 10W-50 Metric is engineered to maintain excellent protection under extremely high temperatures (see performance chart below). It forms a strong protective film<\/strong> and is fortified with premium anti-wear additives to ensure engine protection under all riding conditions.
It prevents sludge and carbon buildup, helping to keep the engine clean and enhancing performance across the board.<\/p>\n

\n

2. Maximum Gear Protection Under Extreme Pressure<\/strong><\/h3>\n

No need for separate gear oil \u2014 AMSOIL 10W-50 Metric provides excellent transmission lubrication and can withstand high pressure loads.
In the FZG Gear Test<\/strong>, it received a perfect score (zero wear)<\/strong>, confirming its outstanding wear protection under stress.<\/p>\n

\n

3. Excellent Rust Protection<\/strong><\/h3>\n

Motorcycles are particularly vulnerable to rust due to environmental moisture. Rust can cause severe engine damage, including increased wear and loss of cylinder compression.
Most conventional oils do not offer adequate rust protection<\/strong>, but AMSOIL 10W-50 Metric includes advanced rust inhibitors<\/strong> and has passed the ASTM D-1748 rust test<\/strong> (refer to Technical Data table).<\/p>\n

\n

4. Maximum Wet-Clutch Performance<\/strong><\/h3>\n

AMSOIL 10W-50 Metric contains no friction modifiers<\/strong> and includes additives optimized for:<\/p>\n

    \n
  • \n

    Smooth gear shifting<\/p>\n<\/li>\n

  • \n

    Timed clutch engagement<\/p>\n<\/li>\n

  • \n

    Effective heat control<\/p>\n<\/li>\n

  • \n

    Slip prevention<\/p>\n<\/li>\n

  • \n

    Spark suppression<\/p>\n<\/li>\n<\/ul>\n

    All of which contribute to longer clutch life<\/strong>.<\/p>\n

    It meets the JASO T903:2006 MA\/MA2<\/strong> and ISO-L-LEMA2 (ISO 24254:2007)<\/strong> wet-clutch specifications.<\/p>\n

    \n

    Applications<\/strong><\/h2>\n

    AMSOIL 10W-50 Metric is recommended for:<\/p>\n

      \n
    • \n

      4-stroke motorcycle engines<\/strong>, air- or liquid-cooled<\/p>\n<\/li>\n

    • \n

      Engines requiring 10W-50<\/strong> motor oil<\/p>\n<\/li>\n

    • \n

      Transmissions requiring gear oil with SAE 80W\/90<\/strong>, API GL-1<\/strong> specifications<\/p>\n<\/li>\n<\/ul>\n

      It is suitable for<\/strong> motorcycles from:
      Kawasaki\u00ae, Yamaha\u00ae, KTM\u00ae, Husqvarna\u00ae<\/strong>, and others requiring 10W-50 engine oil.<\/p>\n

      \n

      \u26a0\ufe0f Not recommended<\/strong> for applications requiring API GL-4 or GL-5 gear oil<\/strong>.<\/p>\n<\/blockquote>\n

      \n

      Compatibility with Other Oils<\/strong><\/h2>\n

      AMSOIL 10W-50 Metric is compatible with other synthetic and conventional engine oils<\/strong>. However, mixing with other oils reduces performance and shortens oil life<\/strong>.
      AMSOIL does not guarantee extended drain intervals<\/strong> if used in combination with other oils, and does not recommend the use of aftermarket oil additives<\/strong>.<\/p>\n

      \n

      Service Life<\/strong><\/h2>\n

      AMSOIL 10W-50 Metric Synthetic Motorcycle Oil supports extended drain intervals<\/strong> under the following conditions:<\/p>\n

        \n
      • \n

        On-Road Use:<\/strong><\/p>\n

          \n
        • \n

          Up to 1 year<\/strong> or twice the OEM-recommended drain interval<\/strong>, whichever comes first<\/p>\n<\/li>\n

        • \n

          (Typically 10,000\u201312,000 km<\/strong> or 1 year)<\/p>\n<\/li>\n<\/ul>\n<\/li>\n

        • \n

          Off-Road Use:<\/strong><\/p>\n

            \n
          • \n

            Follow OEM-recommended drain intervals<\/strong><\/p>\n<\/li>\n<\/ul>\n<\/li>\n<\/ul>\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n\n
