Essential Information
- Water cooled engines utilize a liquid coolant (usually water or a mixture of water and antifreeze) to absorb heat from the engine.
- While it’s theoretically possible, converting an air cooled Bonneville to water cooled would be a complex and expensive undertaking.
- How often should I change the coolant in a water cooled Bonneville.
Triumph’s Bonneville is an iconic motorcycle that has been captivating riders for decades. Its timeless design and evocative engine note have cemented its place in motorcycle history. However, beneath its classic exterior lies a pivotal question: air cooled vs water cooled Triumph Bonneville?
Air Cooled: The Traditionalist’s Choice
Air cooled engines have been a staple of the Bonneville since its inception. They rely on the natural flow of air to dissipate heat from the engine. This design is lightweight, simple to maintain, and offers a distinct mechanical sound that resonates with enthusiasts.
Advantages:
- Lighter weight
- Simpler maintenance
- Classic appearance and sound
Disadvantages:
- Reduced cooling efficiency at low speeds or in hot climates
- Potential for overheating under extreme conditions
Water Cooled: The Modern Approach
Water cooled engines utilize a liquid coolant (usually water or a mixture of water and antifreeze) to absorb heat from the engine. This coolant is circulated through the engine by a pump and then cooled by a radiator.
Advantages:
- Superior cooling efficiency, even at low speeds or in hot climates
- Reduced risk of overheating
- Improved engine performance and reliability
Disadvantages:
- Heavier weight
- More complex maintenance, including coolant changes
- Slightly less traditional appearance
Comparing Air Cooled vs Water Cooled Triumph Bonnevilles
Cooling Efficiency: Water cooled engines clearly excel in this area, providing consistent cooling regardless of operating conditions.
Weight: Air cooled Bonnevilles are typically lighter than their water cooled counterparts, offering a more agile handling experience.
Maintenance: Air cooled engines are generally easier to maintain, with fewer components and less frequent coolant changes.
Appearance: Water cooled Bonnevilles may have a slightly more modern appearance due to the presence of a radiator.
Performance: While water cooled engines offer improved cooling efficiency, air cooled Bonnevilles are known for their distinctive sound and character.
Which Bonneville is Right for You?
The choice between air cooled and water cooled Triumph Bonneville depends on your individual preferences and riding style.
Consider an air cooled Bonneville if:
- You prioritize a lightweight, classic motorcycle with a traditional sound.
- You ride primarily in moderate climates.
- You prefer simpler maintenance.
Consider a water cooled Bonneville if:
- You value optimal cooling efficiency, especially in hot climates or at low speeds.
- You want improved engine performance and reliability.
- You’re willing to accept a slightly heavier weight and more complex maintenance.
The Evolution of the Bonneville
Triumph has gradually introduced water cooled models into the Bonneville lineup, starting with the Bonneville T100 in 2016. While the air cooled Bonnevilles remain popular, the water cooled models have gained traction among riders seeking a more modern and efficient motorcycle.
The Future of the Bonneville
As the motorcycle industry continues to evolve, it’s likely that water cooled engines will become more prevalent in the Bonneville lineup. However, the air cooled Bonnevilles are expected to remain a staple, catering to riders who value tradition and simplicity.
Embracing the Choice
Ultimately, the decision between air cooled vs water cooled Triumph Bonneville is a matter of personal preference. Both options offer unique advantages and disadvantages, ensuring that there’s a Bonneville for every rider. Embrace the choice and enjoy the iconic experience that only a Triumph Bonneville can provide.
Common Questions and Answers
Q: Which Bonneville is more reliable?
A: Water cooled Bonnevilles generally offer improved reliability due to their more efficient cooling system.
Q: Can I convert an air cooled Bonneville to water cooled?
A: While it’s theoretically possible, converting an air cooled Bonneville to water cooled would be a complex and expensive undertaking.
Q: How often should I change the coolant in a water cooled Bonneville?
A: Triumph recommends changing the coolant every 2 years or 24,000 miles, whichever comes first.
Q: Which Bonneville has a better resale value?
A: Air cooled Bonnevilles typically hold their value better due to their classic status and limited production.
Q: Can I ride an air cooled Bonneville in hot climates?
A: Yes, but be aware of the potential for overheating and take precautions such as avoiding extended idling or riding in heavy traffic.
