The Ninja ZX-4R/ZX-25R HEPTA FORCE TSS Racing Cyclone is a full exhaust muffler developed to achieve high performance on the circuit.


The engine is laid out in a 4-2-1 configuration, which provides easy handling at mid-range speeds while providing sharp acceleration at high speeds.


This silencer is stylish and compact, with a heptagonal cross section combined with a carbon end and tapered shape. By attaching and detaching the included sound diffuser, you can select the volume according to the riding situation.


The weight reduction achieved by the titanium pipe contributes to further performance improvement. The weight is approximately 60% lighter than the standard muffler.


The silencer cover, glass wool, and carbon ends can be remade to support the user's motorcycle life.
