Improved and reinforced MALOSSI valves, allow a better service life over time on powerful and prepared engines, allow better filling of the engine, as well as better evacuation of exhaust gases on your TMAX 500.
After the great successes of the 560cc twin coupled to the Double Power Cam, the valves could not be missing!
These new valves have a larger diameter and are produced with materials of excellence, completely profiled again to obtain the greatest performance at all rpm.
They are perfectly interchangeable with the original ones but to have the best results it is necessary to make a small adaptation to the cylinder head and the pistons (explained in detail in the assembly instructions)
