H2O Radiator

H2O Performance Racing Motorcycle Radiators. Galletto Radiatori High-Performance.

H2O Performance by Galletto Radiatori is a specialist in the design and production of high-performance racing radiators for motorcycles, developed to provide efficient engine temperature control under the most demanding riding and racing conditions.

At Omnia Racing you can find a wide selection of original H2O Performance radiators, with solutions developed for leading sport and racing motorcycles, including oversized water radiators, oil coolers, combined water/oil radiator systems, additional radiators and Racing EVO kits.

On a race-prepared motorcycle, the cooling system is a fundamental component. Keeping engine temperatures under control helps maintain performance, reliability and consistent power delivery, particularly during extended track sessions and competitive racing.

Why Choose an H2O Performance Racing Radiator?

A high-performance motorcycle engine generates a considerable amount of heat. On the racetrack, where the engine operates at high RPM for extended periods, the standard OEM cooling system can become a limiting factor.

According to H2O Performance, engine performance can begin to decrease when temperatures reach approximately 85°C, while under extreme conditions around 118°C, the stated power loss can reach approximately 6–7 HP, in addition to increasing mechanical stress on the engine.

For this reason, an H2O oversized racing radiator should not simply be considered an accessory, but an important technical upgrade when preparing a motorcycle for track and racing use.

Greater heat dissipation capacity helps the engine operate within a more efficient temperature range, particularly under demanding racing conditions.

Complete H2O Performance Radiator Range

The H2O Performance catalogue includes different cooling solutions developed according to the motorcycle and its specific cooling requirements.

H2O Oversized Water Radiators

H2O Performance oversized water radiators are designed to increase heat exchange capacity compared with a standard cooling system and are specifically developed for performance and racing applications.

They are particularly suitable for supersport motorcycles, superbikes and race-prepared bikes used for track days and competitions, where maintaining stable coolant temperatures is essential for consistent performance.

H2O Water + Oil Radiator Systems

For more demanding high-performance applications, H2O develops combined water and oil cooling systems designed to manage both engine coolant and oil temperatures.

Depending on the motorcycle and specific application, these kits may include water radiators, oil coolers, silicone hoses, aluminium pipes, fittings, flanges, brackets and protective radiator guards.

H2O Performance Oil Coolers

H2O oil coolers are available in oversized or additional configurations for selected motorcycle applications.

Controlling engine oil temperature is particularly important on racing engines operating under severe conditions, helping to improve the thermal stability of the entire power unit.

H2O Additional Racing Radiators

H2O Performance additional radiators are designed, where applicable, to work alongside the existing motorcycle cooling system.

They provide an effective solution for racing preparations where increased cooling capacity is required without necessarily replacing the complete original cooling system.

H2O Racing EVO: High-Performance Oversized Radiators

The H2O Performance Racing EVO range represents one of the most advanced solutions developed by Galletto Radiatori.

H2O identifies Racing EVO as its patented oversized radiator, specifically designed for riders, racers and teams requiring maximum cooling performance from their motorcycles.

The EVO range also includes applications for the latest generation of high-performance motorcycles, including oversized water + oil cooling systems for Ducati Panigale V4 models.

H2O Racing Radiator Technology

A racing radiator differs from a standard OEM radiator in much more than its external dimensions.

H2O Performance develops its radiator cores by considering key factors such as tube surface area, airflow, heat dissipation capacity, strength and weight.

Its aluminium racing radiators are engineered to provide an efficient heat exchange surface while maintaining a construction suitable for the particularly demanding conditions of competitive motorcycle racing.

Depending on the motorcycle and radiator configuration, H2O kits can include:

• Oversized water radiator cores

• Oversized oil cooling cores

• All-aluminium racing radiators

• Silicone coolant hoses

• Aluminium pipes and fittings

• Dedicated mounting flanges

• Protective radiator guards

• Racing radiator caps

• Specific brackets and installation kits

The exact configuration and components supplied vary according to the motorcycle model and cooling system.

H2O Performance Radiators for Ducati, BMW, Aprilia, Honda, Yamaha and More

The H2O Performance Radiators range includes applications for many of the world's leading motorcycle manufacturers, including:

Aprilia, BMW, Ducati, Honda, Kawasaki, KTM, MV Agusta, Piaggio, Suzuki, Triumph and Yamaha.

Solutions are available for many popular sport and racing motorcycles, with model-specific configurations that can include oversized water radiators, oil coolers, combined water/oil systems and additional racing radiators.

Compatibility should always be checked according to the motorcycle manufacturer, model, version and production year before purchasing.

H2O Performance: Racing Experience Applied to Motorcycle Cooling

The H2O philosophy comes directly from motorcycle racing. Galletto Radiatori has developed cooling solutions for teams and motorcycles competing in national and international championships, transferring experience gained on the racetrack to the H2O Performance products available to professional teams, racers, tuners and track-day enthusiasts.

This racing experience allows H2O to develop high-performance motorcycle cooling systems for applications where thermal efficiency, durability and reliability are essential.
