Just like any other brake fluid, RF650 will eventually degrade over time through heat and pressure cycling. We're not trying to pull the wool over your eyes with a yarn that promises otherwise. In reality, this is no different to engine or gearbox oil which needs replacing after a hard weekends racing. Other fluids deteriorate sooner and require more maintenance. This can be seen when you bleed brakes and the fluid coming out is a "burnt" looking orange or black colour. This will happen through normal racing use, even when you're not at the limit or temperature threshold of the brake fluid.
Trust in your brakes
What we can promise you though is that ENDLESS RF650 remains stable and consistent through extreme conditions with very little change to performance over its lifetime. This increases it's service life and reduces the overall maintenance cost, resulting in a better value for money product.
