Kawasaki Gear & Wet Brake Oil K61030-004B — OEM dual-purpose lubricant, protects gears & wet brakes

KAWASAKI K61030-004B is the genuine Kawasaki gear and wet brake oil formulated for optimal lubrication and consistent wet-brake performance in Kawasaki motorcycles and utility vehicles.

This OEM fluid is designed to meet Kawasaki's original equipment specifications for gearboxes, final drives and wet brake systems where a combined gear and brake oil is required. Choosing a factory-specified lubricant reduces the risk of compatibility problems, helps maintain smooth gear operation and preserves the friction characteristics wet brakes rely on. Because it’s a Kawasaki-labeled product, it’s suited for models and service situations the factory intended — especially where aftermarket or generic oils might alter brake feel or accelerate wear.

What does this oil do for my motorcycle’s wet brakes and gears?

The K61030-004B oil provides both gear protection and controlled friction for wet braking systems. It lubricates gear teeth and bearings to reduce wear, while maintaining the stable friction properties that wet brake plates need to deliver predictable stopping power. Because it balances lubrication and friction control, you get a single fluid that preserves shifting performance and braking feel.

• Dual-purpose formulation: protects gears and supports wet-brake friction.
• Reduces metal-to-metal wear in transmissions and final drives.
• Formulated to maintain consistent brake modulation under load.

How do I use KAWASAKI K61030-004B during routine service?

Using this oil is straightforward: drain the old fluid per your service manual, inspect seals and mating surfaces, then refill to the specified level. Always follow Kawasaki’s recommended fill quantity and service interval for your particular model to retain warranty compliance and peak performance. Dispose of used oil responsibly in accordance with local regulations.

• Drain and inspect: remove old fluid and check gaskets or seals for damage.
• Refill to manufacturer level: use the exact fill volume and check after warm-up.
• Disposal: recycle used oil at an approved collection point.

Which Kawasaki models are compatible with this OEM oil?

This OEM part is intended for Kawasaki models that specify a combined gear and wet-brake oil or list part K61030-004B in their service documentation. Always verify with your owner’s manual or a Kawasaki dealer to confirm fitment. When in doubt, matching the OEM part number ensures the correct friction and lubrication properties for your drive and brake components.

• Designed for Kawasaki motorcycles and utility models requiring a gear & wet-brake oil.
