Slimline Design for Greater Roof Space Versatility

One of the biggest advantages of the Thule Motion 3 Sport is its distinctive narrow-profile design.

Measuring just 65cm wide, this slimline roof box occupies less space across the roof bars than many standard-width cargo boxes.

This can leave room for additional equipment such as a compatible roof-mounted bike carrier, depending on your vehicle and roof rack configuration.

It's an excellent choice for cyclists, skiers and outdoor enthusiasts who want to combine enclosed luggage storage with other roof-mounted accessories.

Always check your available roof bar width and total permitted roof load before fitting multiple accessories.

Practical 300L Storage for Everyday Adventures

The Thule Motion 3 Sport 300L Roof Box offers valuable additional space for suitcases, camping gear, outdoor clothing and travel essentials.

Its practical interior helps keep bulky items out of your vehicle's passenger compartment, freeing up space for a more comfortable journey.

Whether you're travelling on a weekend break, heading to a campsite or packing for a longer holiday, the Motion 3 Sport provides versatile storage without the size of a larger roof box.

Premium Aerodynamic Design

The Thule Motion 3 Sport features a wing-shaped profile with a distinctive forward-leaning nose.

This carefully engineered design helps minimise aerodynamic drag, making it particularly appealing for regular motorway driving and longer road trips.

The roof box combines efficient shaping with a premium Black Glossy finish, giving your vehicle a clean and modern appearance.

Actual fuel consumption and road noise will vary depending on your vehicle, roof bars and driving conditions.

Easy Installation with PowerClick

Thule's innovative PowerClick quick-mount system makes fitting the Motion 3 Sport to compatible roof bars straightforward.

The integrated torque indicator produces an audible click when the mounting hardware reaches the correct tightening force.

This makes it easier to achieve a secure installation without complicated adjustments.

The system is especially convenient for drivers who regularly remove and refit their roof box between trips.

Secure Storage with SlideLock

The SlideLock locking system combines practical security with convenient everyday operation.

Separate opening and locking functions automatically secure the roof box lid when correctly closed.

The system also indicates when the lid is properly locked, helping ensure your luggage and equipment are securely enclosed before travelling.

Dual-Side Opening & One-Handed Operation

The Thule Motion 3 Sport features a convenient dual-side opening design, allowing access to the interior from either side of your vehicle.

Its sturdy lid and wide ergonomic handle provide smooth one-handed opening and closing.

This is particularly useful when loading luggage, organising equipment or accessing items during a longer journey.

The forward-positioned design also helps minimise interference with your vehicle's rear hatch.

Ideal for Skiing & Winter Sports

The Thule Motion 3 Sport Roof Box is a practical option for transporting winter sports equipment.

Its interior can accommodate approximately 3–5 pairs of skis or 3–4 snowboards, depending on equipment dimensions.

With a maximum ski length of 175cm, it's suitable for a range of compatible adult and junior skis.

For additional equipment organisation, the optional Thule Box Ski Carrier Adapter 694-5 is available separately.

Customers carrying longer skis should consider one of Thule's larger or extra-long roof boxes.

Perfect for Scottish Road Trips & Outdoor Adventures

From skiing in the Cairngorms and Glencoe to exploring Loch Lomond and the Scottish Highlands, the Thule Motion 3 Sport 300L Roof Box is designed for active travellers.

Its combination of aerodynamic performance, narrow-profile storage and secure locking makes it especially appealing to cyclists, skiers and outdoor enthusiasts.

Whether you're planning a Scottish weekend away, driving the North Coast 500 or heading to the Alps, the Motion 3 Sport helps make more room for your next adventure.
