DescriptionThe whole story▼

The same silencer as GHO1702TOM, under a matte black ceramic coat. Spark charges a premium for the treatment, and it is the whole of the difference between the two articles.

Key Features

  • Euro5+ homologated slip-on for the Honda CRF1100L Africa Twin and Adventure Sports.
  • Fighter Evo silencer, titanium with matte black ceramic treatment.
  • Carbon fibre heat shield with aerodynamic vents included.
  • 2,4 kg against 5,5 kg for the standard part.
  • Removes the exhaust valve on model years up to 2023 without an ECU error.
  • Not compatible with the original side bags.

Ceramic, Not Paint

A matte black ceramic treatment is applied to the finished titanium and cured onto it. It does not sit on the surface the way a lacquer does, it does not lift at the seams, and it holds its finish through the heat cycles an exhaust on a big single-sided twin puts through it.

What it looks like is flat and light-absorbing rather than glossy. Against the carbon heat shield that comes with the slip-on, the two dark surfaces read as one piece.

Why Anyone Pays the Difference

Nothing measurable changes. Same 2,4 kg, same Euro5+ approval, same construction underneath, same valve device, same heat shield. The coating adds no weight worth listing and takes none away.

What it does is stop the silencer from being the brightest thing on a mostly dark motorcycle. On a black or grey Africa Twin the titanium version announces itself from the far end of a car park; this one does not.

After a Season

Natural titanium changes as it is used. The area around the outlet takes on a gold-bronze tint after the first few hundred kilometres of heat, and where a boot or a pannier rail touches it, the grey goes lighter. Owners are divided on whether that is patina or wear.

A ceramic-treated silencer does not do this. It stays the colour it left the factory, and if it is going on a motorcycle that will be kept clean and sold on in five years, that is worth something beyond the way it looks on day one.

The Valve Device Is Included Here Too

Africa Twins up to model year 2023 have an exhaust valve inside the standard silencer, and the ECU looks for its servo motor. Spark's mechanical solution keeps that circuit satisfied when the valve goes, so the bike runs without a fault light and without a remap.

What Does Not Fit

The original Honda side bags. Spark says so for the whole slip-on range on this motorcycle, and it applies to this article exactly as it does to the titanium one.

Fitment & Compatibility

Honda CRF1100L Africa Twin and Africa Twin Adventure Sports, 2020 to 2026. The natural titanium version is GHO1702TOM. The Dakar slip-ons are GHO1703TOM and GHO1703DOM. The AISI 304 racing collector GHO8501 fits the Adventure Sports only.
