Spark Exhaust Konix Evo Racing Full System Yamaha R7 / MT-07 / XSR700 (2021-2026) GYA8895T

Read the two warnings before anything else: on an R7 this system is not compatible with the passenger footrests, and Spark specifies it is to be installed with racing fairings. Everything after that is about how good the exhaust is.

Key Features

• Racing full system for the Yamaha YZF R7, MT-07 and XSR700, 2021 to 2026.
• AISI 304 stainless steel headers with a Konix Evo titanium silencer.
• Conical titanium body with a sharply contoured carbon fibre end cap.
• 4,7 kg against 7,6 kg standard: 2,9 kg saved.
• dB killer G9999 available as an optional insert.
• On the R7: no passenger footrests, racing fairings required.

Two Conditions on an R7

Spark prints both in capitals on its own page. Fitted to a Yamaha R7 this system is not compatible with the passenger footrests, and it is to be installed with racing fairings. Neither is a suggestion.

What that means in practice is that the R7 this exhaust belongs on is a track bike, not a road-registered machine with a pillion seat. If your R7 still carries its standard bodywork and you want to keep it that way, this is not the system to order.

The Konix Evo Case

Spark describes it as an evolution of its own design with a deeply racing soul, and the shape backs that up: a conical titanium body ending in a carbon fibre cap with sharp contours rather than a rolled edge.

Against the R7's angular tail it reads as part of the motorcycle. On an MT-07 or an XSR700, where the silencer hangs in open air, it is simply the most visible thing on the bike.

Stainless Headers, Titanium Can

The headers are AISI 304 stainless — the material Spark uses where a part has to survive a season of track use and the occasional crash. The weight saving comes from the silencer, and 2,9 kg off a 689 cc twin is a real number rather than a rounding.

Spark's own claim about the fit is worth quoting: extremely precise joints and fittings, a professional plug and play experience. On a system that has to line up through two headers and a link section, that is not nothing.

The dB Killer Is Optional

Unlike Spark's older MT-07 system, this one does not include a noise insert. The silencer is prepared for the optional dB killer G9999, which you order separately if a circuit asks for a quieter figure.

Where It Came From

Spark says the two R7 systems were born from experience gained in the most prestigious championships, and they were engineered to improve power delivery rather than to chase a peak number. The company has been building for the CP2 platform since the MT-07 arrived.

Fitment & Compatibility

Yamaha YZF R7, MT-07 and XSR700, 2021 to 2026. The Force Evo alternative on the same headers is GYA8896T at 1.536 euro. Spark's older Grid-O system for the MT-07 platform is GYA8876T.

Road Approval

None. Spark lists this system as not approved; it is built for closed-circuit use and must not be fitted to a motorcycle ridden on public roads.
