Another significant difference is the cooling system. The Bonneville 2009 relies on air cooling, while the Bonneville T120 2021 features liquid cooling. Liquid cooling is generally more efficient and allows for better temperature regulation, which can result in improved engine performance and longevity.

In terms of displacement, the Bonneville T120 2021 has a larger engine with a displacement of 1200 ccm, compared to the 865 ccm of the Bonneville 2009. This increase in displacement will likely contribute to the T120's higher power and torque figures.

Both models feature suspension from Kayaba and dual shock absorbers at the rear. However, the Bonneville T120 2021 benefits from upgraded front brakes with Brembo brand calipers, which are known for their superior stopping power and performance.

In terms of dimensions and weights, the Bonneville T120 2021 has a slightly smaller front tire diameter of 18 inches compared to the 17 inches of the Bonneville 2009. The wheelbase remains the same at 1450 mm for both models. The seat height of the T120 is slightly higher at 790 mm compared to the 751 mm of the Bonneville 2009. Additionally, the Bonneville T120 2021 has a slightly smaller fuel tank capacity of 14.5 liters compared to the 16 liters of the Bonneville 2009.
