DescriptionThe whole story▼

Two point three kilograms off a 190 kg motorcycle with 43 horsepower. In percentage terms this is one of the biggest weight savings Akrapovic publishes — 54.8 per cent — and on a bike this size it is the kind of change a rider can actually feel when flicking it into a corner.

Key Features

  • 1.9 kg against the standard 4.2 kg: 2.3 kg and 54.8 per cent less
  • Carbon fibre construction
  • 0.6 PS more at 7,600 rpm and 0.8 Nm at 5,200 rpm
  • Removable noise insert included
  • One part for the roadster, the adventure bike and the sportsbike
  • EC type approval — read the approval note before ordering

Three Motorcycles, One Exhaust

Honda's 471 cc parallel twin platform gave three very different machines the same rear end: the naked CB500F, the tall CB500X and the faired CBR500R. Japan and some other markets got 400 cc versions of all three. This silencer fits all of them.

These are A2 licence motorcycles, bought new by riders early in their motorcycling and kept for years. A carbon silencer is often the first thing that goes on one.

Why the Percentage Is So High

Honda's standard silencer for this platform is a 4.2 kg steel box — heavy for a 47 PS twin, because it has to do all the emissions and noise work in one unit at the lowest possible cost. Carbon and a proper internal design take more than half of that away.

An Insert Is Included

The exhaust ships with a removable noise insert. Fitted, it keeps the exhaust within its approved noise figure; removed, it opens the sound up. Removing it means the exhaust no longer matches the condition it was approved in, so it belongs on a closed circuit and not on the road.

Road Approval

Akrapovic records an EC type approval for this exhaust. No separate ECE approval is listed. For registration in Germany an EC type approval is normally sufficient, but if you need proof of ECE conformity for a particular authority, please contact us before ordering and we will check the current certificate with Akrapovic.

Living With Carbon

A carbon silencer wants slightly different care than steel. Wash it rather than let road salt sit on it over winter, and keep chain lube off the sleeve — the weave is lacquered, and thrown lube marks it in a way that does not polish out.

Handled reasonably it will outlast the motorcycle. Carbon does not corrode, which on a bike that spends years commuting is the more relevant property.

Fitment and Compatibility

S-H5SO2-HRC covers the Honda CB500F and CB400F from 2013 to 2015, and the CB500X, CB400X, CBR500R and CBR400R from 2013 to 2016. It does not fit the 2024 CBR500R with the E-Clutch.
