MOOSE OFFROAD 212-1112 1.1 Bar Radiator Cap — Stock Replacement for Japanese Motorcycles

MOOSE OFFROAD — Universal Japanese Fitment, Corrosion-Resistant Silicone, and Essential Cooling Troubleshooting

Troubleshoot your cooling issues the smart way with the MOOSE OFFROAD 212-1112 Stock Replacement Radiator Cap. Often overlooked, a faulty radiator cap is a primary cause of mysterious coolant loss and engine overheating. This 1.1 Bar cap is designed as a direct, economical replacement for the original equipment on a wide range of Japanese-manufactured motorcycles, ATVs, and UTVs. By maintaining the correct system pressure, it ensures your coolant stays in the radiator where it belongs, rather than being prematurely dumped out of the overflow hose.

Built for the rigors of off-road and street use, this cap features high-temperature, corrosion-resistant silicone seals. Unlike standard rubber seals that can harden and crack over time due to thermal cycling, these silicone seals maintain their elasticity to provide a consistent, leak-proof barrier. Whether you are prepping your machine for a cross-country adventure or performing routine maintenance on your motocross bike, this "Stock Style" cap is the easiest and most cost-effective way to ensure your cooling system is operating at its factory-intended pressure.

• 1.1 Bar Pressure Rating: Matches the standard OEM pressure requirements for most Japanese liquid-cooled engines.
• Universal Japanese Fit: Designed to fit the radiator necks of most Honda, Yamaha, Kawasaki, and Suzuki models.
• Premium Silicone Seals: High-temperature and corrosion-resistant material prevents seal fatigue and water leakage.
• Essential Troubleshooting: The fastest way to solve issues with steam or fluid escaping through the overflow hose.
• Durable Construction: Black finish designed to withstand extreme vibrations and harsh off-road environments.

Moto-House MX Pro Tip:

If your bike is "puking" coolant after only a few minutes of riding, don't assume the worst. A weak spring or a degraded seal on your radiator cap is often the culprit. The MOOSE OFFROAD 212-1112 is a "tool box essential"—keep one as a spare to quickly rule out cap failure during a race or trail ride. Safety Reminder: Never attempt to remove or replace a radiator cap while the engine is hot. Always wait for the system to be cool to the touch to avoid serious steam burns.

FAQ Questions

Q) Will this fit my KTM or Husqvarna?
A) No, European models (KTM/Husqvarna/Gas Gas) typically use a different radiator neck size and higher pressure ratings (1.8 - 2.0 Bar). This cap is designed for Japanese models (Honda/Yamaha/Kawasaki/Suzuki).

Q) How do I know if my current cap is bad?
A) Look for white crusty residue around the cap, a flattened/cracked rubber seal, or fluid consistently leaking from your overflow hose before the bike is actually overheating.
