A replacement cap is the least expensive and easiest way to solve or troubleshoot your liquid-cooled bike/ATV radiator problems. Upgrading to a high pressure 1.6 bar, 1.8 bar or 2. 1 bar from the stock radiator cap is the simplest and least expensive way to avoid over-boiling your engine. Raising your cooling system’s maximum operating pressure increases your coolant’s boiling point, allowing you to ride harder and longer. Old and faulty radiator caps can cause steam and fluid to be pumped out of the radiator overflow hose. High-temperature corrosion-resistant silicone seals. Universal fit for most Japanese models. Black finish PRESSURE OPTIONS- 1.1 Bar is the typical stock replacement for a Japanese model. 1.6 Bar is a small pressure upgrade to help prevent boiling over in standard to moderate conditions. Upgrade hose clamps and check regularly, Spring clamp style NOT acceptable. This is also our recommended cap when using Evans Coolant. 1.8 Bar is a moderate pressure upgrade. It can help prevent boil over in moderate to harsh conditions. Upgrade hose clamps and check regularly, Spring clamp style NOT acceptable. 2.1 Bar is a major pressure upgrade, almost double the standard cap. It can help prevent boil over under severe conditions. Upgrade hose clamps and check regularly, Spring clamp style NOT acceptable. Show more
