Spark Exhaust Konix Evo WSSP600 Replica 3/4 Kit Triumph Street Triple 765 (2020-2026) GTR0509T

The World Championship silencer, on a link pipe you can fit to a standard motorcycle. Spark's WSSP600 replica kit uses the same Konix Evo case that runs in the SuperSport 600 World Championship, on an AISI 304 pipe with a carbon heat shield — 2.5 kg in total.

Key Features

• 3/4 racing kit for the Triumph Street Triple 765, 2020 to 2026.
• Konix Evo silencer: the same case used in the SuperSport 600 World Championship.
• AISI 304 stainless link pipe with carbon fibre heat shield.
• 2.5 kg complete.
• 106 dB at 5,000 rpm without the dB killer, 99 dB with it.
• Not compatible with the passenger footrests. dB killer not included.

Three Published Readings

Spark measured this kit against the standard exhaust and printed all three numbers: the original at 97 dB at 5,415 rpm, this kit at 106 dB at 5,000 rpm with nothing fitted, and 99 dB at the same speed with the G9999 dB killer in place.

Nine decibels over standard is a great deal of noise, and seven of them come back with a plug that costs very little. Those figures are the honest basis for deciding whether this kit belongs on a road bike, a circuit bike, or a circuit bike that occasionally has to pass a sound check. Spark does not supply the dB killer with the kit, so order it if you need the lower number.

A Replica That Fits the Standard Bike

Spark's actual WSSP600 system requires a racing oil pan. This kit exists because most Street Triples do not have one: Spark redesigned the manifold routing specifically so the World Championship silencer can be fitted to an unmodified motorcycle.

What carries over is the part that matters. The Konix Evo here has the same titanium body and carbon fibre end cap as the championship silencer, not a road-going interpretation of it.

What It Mounts To

The answer depends on the model year, and Spark is explicit. On bikes up to MY2022 this kit fits either the original manifold or Spark's GTR8502 racing manifold. From MY2023 it must be combined with the GTR8502 racing manifold and the SKIT112 mounting parts.

Check that before ordering, because on a 2023-and-later bike the kit alone is not a complete purchase. The passenger footrests cannot be retained in any case.

Fitment & Compatibility

Triumph Street Triple 765 R, RS and S, 2020 through 2026. The Force Evo alternatives on the same link pipe are GTR0510T at 350 mm and GTR0511T at 400 mm. The dB killer is G9999. For MY2023 onwards, GTR8502 and SKIT112 are required.

Road Approval

None. The kit carries no EC certificate, and at 106 dB without the dB killer it is well above the level Spark's homologated systems for this bike produce.
