New handcrafted radiators, made with care using sophisticated and selected materials, are different for each type of motorcycle so that you can get the best performance and the least weight.

The H2O brand is synonymous with quality and professionalism. It is a leading manufacturer of high-performance radiators and the official supplier of numerous SBK teams.

With these high-performance radiators, you will achieve maximum performance while reducing the bike's weight.

The Hard Facts

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 could lose 6-7 HP and ultimately risk the threat of severe damage. Cooling problems are a significant cause of failures in all types of racing: the radiator is essential to the performance and longevity of your racing engine.

How does it work

The radiator removes the engine's unused heat. This is accomplished by the fluid that carries the engine's heat into the radiator. Once in the radiator, the fluid moves through the tube/fin, dissipating the engine's heat.

Why an Aluminum Racing Radiator

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

Most street application radiators are designed to get the job done for the lowest possible cost. As a result, most stock/OEM radiators are adequate for cooling a motorcycle engine during normal usage. Forget about under the stresses of racing. The tubes in a radiator are the primary cooling source, 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 aluminium racing radiator does just the opposite. More tube surfaces for primary cooling and fewer fins allow it to cool much more effectively. The increased fins on a stock/OEM radiator can also adversely affect the radiator's performance. 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 are present. Additionally, the higher fin count can represent a slight air restriction, which causes air to flow around the sides of the radiator rather than through it. One additional thing to remember 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 aluminium racing radiators are strength and weight. Most aluminium racing radiators have the tanks welded to the tubes rather than brazed or sealed with epoxy, which makes the radiator much stronger and more capable of withstanding the rigours of racing. Because of the lighter materials and lower fin counts, aluminium racing radiators are much lighter than stock/OEM radiators.
