Spark Exhaust Konix Slip-On Titanium Euro 4 / Euro 5 Honda NC700 / NC750 S / X (2012-2022) GHO1103TOM

An approved titanium silencer for a motorcycle nobody makes exhausts for. Spark's Konix slip-on fits the whole NC700 and NC750 family and carries a certificate for Euro 4 and Euro 5.

Key Features

• Homologated slip-on for the Honda NC700 S and X and NC750 S and X.
• Konix silencer in titanium with a stainless steel connecting pipe.
• Lateral mounting, in the standard position.
• 2,1 kg against 3,4 kg standard.
• Approved for both Euro 4 and Euro 5.
• Made by Spark in Mantova, Italy.

Two Emission Classes, One Certificate

The NC platform ran long enough to span two emission standards, and Spark's approval covers both Euro 4 and Euro 5. On a model line that has been in production for over a decade that is the specification worth checking first, because a certificate written for one class is worthless on a bike registered under the other.

Send us the year and emission class from the registration document if you are not sure, and we will confirm it before anything ships.

The Konix Case

Konix is the angular one in Spark's range: flat flanks tapering to a squared outlet rather than a rolled tube. On an NC750X, which Honda drew with hard surfaces and a deep flank, it fits the motorcycle better than a round case would.

The case is titanium; the connecting pipe is stainless steel, which is the sensible split on a commuter machine that sees salt.

One Point Three Kilos

3,4 kg standard, 2,1 kg fitted. The NC is not a light motorcycle and this does not change that, but the standard silencer is a large steel item and replacing it is the one weight change available to an owner.

An Unusual Engine to Build For

The NC's 700 and 750 twin is a low-revving, long-stroke engine with a red line under 7.000 rpm — closer to a car engine than to a sports twin. An exhaust for it has to work at low engine speeds, which is a different problem from making a supersport louder at 10.000 rpm.

Standard Mounting

The silencer sits laterally, where Honda put the original, on a stainless connecting pipe. The manifold and the catalytic converter stay standard, which is what the certificate is written around and why the fitting is straightforward.

Made in Italy, and What That Buys

Spark builds in Mantova: the titanium case, the TIG welding and the finishing all happen in one factory. On a model line this long-lived, a manufacturer that still holds an article number and can supply a certificate for it years after launch is worth something on its own.

What Comes Off the Motorcycle

The silencer and its connecting pipe. Manifold, catalytic converter and sensors all stay as Honda built them, which is the basis of the approval and the reason the job is an hour with hand tools.

Fitment & Compatibility

Honda NC700S, NC700X, NC750S and NC750X, and the related models Spark lists on the same platform. Ask us with your exact model and year and we will confirm the certificate scope.

Road Approval

EC type-approved for Euro 4 and Euro 5. Spark supplies the homologation certificate with the part.
