DescriptionThe whole story▼

The Moto2 silencer, carried high beside the tail. Spark's laterally mounted Euro5+ system pairs the Grid-O — the case that won the 2020 world championship — with a catalysed 3-in-1 pipe that keeps the Street Triple road legal.

Key Features

  • Euro5+ homologated full system for the Triumph Street Triple 765 R, RS and S, 2023 to 2026.
  • Grid-O silencer, laterally mounted: full titanium, visible TIG welding, titanium grid.
  • 6.1 kg against 9.6 kg standard — 3.5 kg saved.
  • AISI 304 collectors, CNC-machined connections, compensators.
  • Special catalytic converter with racing cells inside the 3-in-1 pipe.
  • Dual lambda sensor setup with a plug for single-sensor bikes.

A Racing Silencer With Papers

The Grid-O in this system is not a road-going interpretation of a race part. Spark states it is the same silencer that won the 2020 Moto2 world title: entirely titanium, TIG welds left visible, with a titanium grid that Spark says emphasises both the sound and the look of the Street Triple.

What makes it road legal here is everything in front of it. The catalyst and the pre-silencer box do the compliance work, which frees the silencer itself to stay exactly as the racing department drew it. That is an unusual arrangement and the reason this system reads as more serious than most homologated exhausts.

Lateral, and Why It Costs More

Spark offers this system in a low mount and in this lateral one. The lateral version costs noticeably more than the low mount and weighs two hundred grams more.

What that buys is position. On a naked motorcycle the exhaust is not hidden behind bodywork, and a silencer carried out beside the seat unit changes the profile of the bike from behind in a way tucking it under the tail does not. It also lifts the case clear of the swingarm and away from the rear wheel's spray. Neither version alters the homologation.

Performance Without a Remap

Spark's stated goal for the homologated range was to allow normal road use and raise performance at the same time, without any ECU modification. The catalyst is how that is done: racing cell count and a rich noble-metal impregnation, so it cleans the gas without behaving like a restriction.

For an owner that means no dyno time, no flashed map, and no conversation with the dealer about what has been changed.
