DescriptionThe whole story

Two BMW part numbers you will need if you have a Scrambler. Akrapovic names them: the aluminium muffler holder 77 11 8 564 071 is required, and the covers 77 25 8 536 857 are recommended to hide the exposed threaded fasteners on the main frame once the pillion frame comes off.

Key Features

  • 2.28 kg against the standard 4.36 kg: 2.08 kg and 47.7 per cent less
  • EC and ECE type approved, plus EPA
  • Titanium construction
  • 1.2 Nm more at 2,650 rpm — just above idle on a boxer
  • For the low-mounted silencer position
  • Twenty minutes to fit — the quickest link pipe in this catalogue
  • Covers the Euro 5 R nineT family from 2021 to 2023

The Euro 5 Machines

BMW revised the R nineT for 2021 to meet Euro 5, and the standard mid-section came down from 8 kg to 4.36 in the process. That is why this pipe saves 2.08 kg where the earlier one saved 5.5 — BMW had already done half the work.

It also explains the smaller power figures. There is less restriction left to remove.

What You Need for a Scrambler

The low-mounted slip-on with this link pipe fits the R nineT Scrambler only if the pillion passenger frame is removed. Then BMW's aluminium muffler holder must be fitted, and BMW's fastener covers are recommended so the exposed threads on the main frame do not show.

Three parts and a permanent change to the bike's two-up capability. Worth deciding before you order, not during the fitting.

Twenty Minutes

The shortest fitting time of any link pipe in this catalogue. A boxer puts the mid-section in the open, and on a machine on its centre stand there is nothing to remove first.

Low or High on the Euro 5 Machines

Akrapovic builds two pipes for the 2021 to 2023 R nineT, and the difference is sharper than on the earlier bikes. This low one saves 2.08 kg; the high one saves 1.56. The power figures are identical.

So on the Euro 5 machines the low pipe is lighter, cheaper and keeps the passenger footpegs. The high one is bought for the look, and this page will say so.

Titanium on a Short Pipe

A mid-section is short, so the material cost of titanium is small and the weight saving is proportionally large. That is why Akrapovic uses it here and steel on longer, more exposed pipes elsewhere in the range.

Which Silencer Position

BMW's R nineT platform accepts the silencer high or low, and the link pipe is what decides it. This is the low one. If your bike already runs an Akrapovic slip-on in the low position, this is the pipe that completes the system.

Road Approval

EC and ECE type approval are both in place, with EPA for the United States. No entry in the vehicle documents is needed.
