Developed in conjunction with Factory World SuperBike and SuperSport racing teams, these innovative new solutions from Galletto Radiatori / H2O Performance are the only radiators capable of cooling the most extreme race bikes to the range of between 80-90° Celsius!  This is over 10° Celsius cooler than other racing radiators. 

Functionality:

The more horsepower an engine develops the more heat it creates. Once an engine reaches around 85°C (185°F) you start losing power and at about 118°C (244.4°F) you can lose considerable power and ultimately risk the threat of serious damage. Cooling problems are a major cause of failures in all types of racing: the radiator is important to the performance and longevity of your racing engine. 

Why an Aluminum Racing Radiator?

Although the concept of a radiator is quite simple, getting a radiator to work properly under the extreme conditions of auto racing is not as simple. Most stock motorcycle radiators are not designed to stand up to the stress of racing, this includes both their strength and performance. 

Most radiators for street applications are designed around the principle of getting the job done for the lowest possible cost. As a result most stock/OEM radiators are merely adequate for the task of cooling a motorcycle engine during normal usage. Forget about under the stresses of racing. The tubes in a radiator are the primary source of cooling and the fins are secondary. Since tubing is much more expensive than fins, most stock/OEM radiators increase the amount of fins to reduce the amount of costly tubing required. A good aluminum racing radiator does just the opposite. More tube surface for primary cooling and fewer fins allowing it to cool much more effectively. The increased number of fins on a stock/OEM radiator can also adversely affect the performance of the radiator. Since additional fins allow less space for dirt and debris to pass through, it becomes harder for the air required to dissipate heat to pass through the radiator. 

This is very important in racing where more dirt, rubber and other debris is present. Additionally, the higher fin count can represent a small air restriction, which causes air to flow around the sides of the radiator rather than through it. One additional thing to keep in mind is that most stock motorcycle radiators are designed to work with unrestricted airflow. When placed behind bodywork it becomes much harder for them to work efficiently. 

Two additional benefits of aluminum racing radiators are strength and weight. Most aluminum racing radiators have the tanks welded to the tubes rather than brazed or sealed with epoxy. This makes the radiator much stronger and more capable of standing up to the rigours of racing. Aluminum racing radiators are also much lighter than stock/OEM radiators because of the lighter materials and lower fin counts.
