The rear end of Spark's 60 mm range for the ZX-6R, sold as a group: the Force Evo silencer in titanium, 400 millimetres of case, with the fittings that connect it to a 60 mm pipe. Order it to replace a damaged one, or to change the character of a system that is otherwise fine.
Key Features
- Force Evo silencer group for the Kawasaki ZX-6R, ZX-6R Ninja and Ninja ABS 636.
- Titanium, 400 mm case length.
- 60 mm inlet, matching Spark's stainless collector for this motorcycle.
- Supplied as a group, not as a bare case.
- Racing part, no homologation.
Four Hundred Millimetres
Length is the first thing that decides how a silencer behaves. At 400 mm this is a long case for a 600, which gives the packing enough volume to work on the mid-range rather than only trimming the top - and it gives the ZX-6R a proportion that reads more endurance than sprint.
It is also the length that fills the space under a standard tail without needing a different hanger, which is why Spark keeps it in the range rather than shortening everything.
Group, Not Just a Case
Spark's price list distinguishes carefully between a silencer and a silencer group. The group is what you can actually bolt to a motorcycle: the case plus the connecting hardware sized to the 60 mm interface. A bare case would leave you sourcing clamps and a bush and hoping the diameters agree.
For the ZX-6R the group is the sensible unit to buy, because it is exactly what comes off when a silencer is damaged.
Force Evo, in Short
The Force Evo case is the ribbed one - the ribs run back along the titanium body and converge towards the end cap, which both stiffens the sleeve and gives it the taper that identifies it at a glance. It is Spark's design for riders working to a noise limit rather than chasing the loudest option.
Fitment & Compatibility
Kawasaki ZX-6R, ZX-6R Ninja and Ninja ABS 636, 2009 to 2026, on Spark's 60 mm systems. The Konix Evo alternative at the same interface is GKA8822ST. The stainless collector is GKA8806, the link pipe SGKA8806*01 and the frame bracket SGATT236. Assembled systems: GKA8806T and GKA8822T.
