Getting the correct hydraulic fork oil is essential not only for protecting your forks’ delicate internals and seals, but also for maintaining ride comfort and control. Using the wrong oil can affect how your suspension responds, leading to poor handling, reduced stability and increased wear over time.

Fork oil controls the movement of suspension by regulating how quickly it can compress and rebound. In simple terms, the heavier the oil (or the higher the viscosity), the more resistance it provides to movement within the fork. When it comes to fork oil, 15W is a common requirement, often in older motorbikes, as well as some modern mountain bikes.

At Opie Oils, we stock a wide range of 15W fork oils suitable for various motorcycles and riding conditions. Whether you’re maintaining your suspension or fine-tuning your setup, you’ll find high-quality fork fluids designed to deliver consistent performance and reliable protection.
