A Yamaha 90 Motocross bike typically requires a high-quality two-stroke oil, specifically designed for small engines. It's important to use oil that meets the manufacturer's specifications for optimal performance and engine protection. Brands like Yamalube or other reputable two-stroke oils can be used, mixed at the recommended fuel-to-oil ratio, often around 32:1 or 50:1, depending on the model year. Always refer to the owner's manual for specific recommendations.
