Whether you race motocross, hare scrambles or other events; or hit the trails on weekends with family and friends, you typically have one goal in mind: ride faster and more effectively. In racing, getting out of the gate quickly and grabbing the holeshot is critical to finish on the box. On the trail, you often must modulate the clutch to maneuver around obstacles and tame challenging terrain on your way to the front of the pack.

Clutch slippage or inconsistent clutch feel, however, can lead to slow starts out of the gate and ineffective riding on the trail. To solve that problem, we introduced AMSOIL Synthetic Dirt Bike Oil last year. The lubricant was fine-tuned to deliver confident clutch feel and excellent clutch protection. However, some riders prefer a dedicated dirt bike transmission fluid instead of a multi-purpose motor oil. For them, new AMSOIL Synthetic Dirt Bike Transmission Fluid features a wet-clutch-compatible formulation designed to prevent clutch slippage and deliver consistent, confident clutch feel. It helps enthusiasts ride smoother and faster for maximum performance.

It also provides excellent wear protection for gears and clutch plates. It helps reduce time and money spent on maintenance, helping enthusiasts spend more time riding.

Revised Recommendations

If you are currently satisfied using AMSOIL Synthetic Dirt Bike Oil in your dirt bike transmission, there’s no need to change anything. However, Synthetic Dirt Bike Transmission Fluid is now the primary recommendation for all two-stroke bikes, since two-strokes use a separate sump. Many two-stroke riders look for lubricants labelled specifically for the transmission, and this adjustment is designed to suit their needs.

The four-stroke market segment is slightly different. The popular Honda* CRF is the only four-stroke bike that uses a separate sump, but because the owner’s manual recommends using the same oil in the engine and transmission, AMSOIL Synthetic Dirt Bike Oil remains the primary recommendation. Synthetic Dirt Bike Transmission Fluid is the secondary recommendation.

For all other four-stroke bikes, AMSOIL Synthetic Dirt Bike Oil is the primary – and only – recommendation. For specific product recommendations, consult the Motorcycle Product Guide on
