Tusk High-Pressure Radiator Cap with Temperature Gauge 1.8–2.0 kg/cm2 | Honda CRF450R, CRF250R, Yamaha YZ450F, YZ250

Precision Cooling On The Trail

The Tusk High-Pressure Radiator Cap with Temperature Gauge is engineered to give riders quick visibility into their machine’s cooling status. By elevating the boiling point with a higher cap pressure, it helps you maintain steady performance during demanding rides, while the top mounted gauge provides an instant read on running temperature.

Key Benefits At A Glance

• Fitment Across Multiple Models — designed to work with Honda CRF450R, CRF250R, Yamaha YZ450F, and YZ250 families (see fitment guide image).
• Higher Pressure Rating — boosts the coolant boiling point to help minimize boil-overs in hot conditions or sustained climbs.
• Built-In Temperature Gauge — a quick glance shows whether the engine is running hot or cool, enabling informed decisions on the trail.
• Two Pressure Options — choose from 1.8 kg/cm2 (25.6 psi) or 2.0 kg/cm2 (28.5 psi) to suit your riding environment.

Real-World Scenarios

Whether you are blasting through desert air, climbing steep grades, or towing a line in a crowded motocross track, this cap offers a practical way to monitor cooling without slowing down. The gauge on top is designed for quick interpretation, so you can assess conditions at a glance and adjust your pace if needed.

The design emphasizes reliability in rugged environments. The higher pressure rating is paired with a straightforward installation, making it a sensible upgrade for riders who want a straightforward, no-fuss accessory that complements their bike’s cooling system.

Fitment And How It Works

The cap is compatible with a range of models, and fitment is confirmed via the image guide included with the product. The temperature gauge provides a simple status check, while the elevated pressure rating helps manage coolant behavior under heat and load. Two options give you flexibility to match your typical riding climate and engine setup.
