DescriptionThe whole story▼
The Akrapovic Racing Line S-B10R1-RC is a purpose-built full exhaust system for the BMW S1000RR K46, crafted from high-grade V4A stainless steel and finished with a hexagonal carbon-shelled silencer and carbon end cap that speak directly to Akrapovic's racing heritage. Every detail of this system — from the sculptural 4-into-2-into-1 header configuration to the all-titanium silencer internals — is engineered for riders who refuse to compromise on design or performance.
Key Features
- Dramatic weight saving of 6.3 kg versus the standard system (stock: 11.8 kg, Akrapovic: 5.5 kg), transforming the feel of the S1000RR at every corner exit
- Power gain of 5.8 hp at 13,400 RPM (stock: 185.5 hp, Akrapovic: 191.3 hp) alongside a torque increase of 8.9 Nm at 8,200 RPM
- 4-into-2-into-1 V4A stainless steel construction with lambda connection for clean, optimised gas flow
- Hexagonal silencer body with carbon fibre outer sleeve and carbon fibre end cap — a signature Akrapovic race-track aesthetic
- All metallic silencer components including internals constructed from titanium for maximum heat resistance and minimal mass
- Supplied with a dB-Eater (V-TUV108/1) for controlled noise output at track days
- Optional exhaust bracket available when passenger footpegs are removed, keeping the installation clean and purposeful
Design, Finish and Heritage
Akrapovic has defined the sound and look of superbike racing for decades, and the Racing Line system for the S1000RR K46 distils that legacy into a package optimised for the 2010–2014 generation of BMW's flagship. The contrast between the brushed stainless steel headers and the deep weave of the carbon silencer sleeve is unmistakably purposeful — this is not styling for its own sake but a visual expression of the materials science underneath. The titanium internals reinforce that message: every gram saved has been earned through considered engineering rather than superficial trimming.
Performance on Track
With nearly six additional horsepower cresting at 13,400 RPM and close to nine extra newton metres of torque available from 8,200 RPM, the Racing Line transforms the already formidable S1000RR power delivery into something sharper and more responsive throughout the mid-range. The weight reduction of 6.3 kg is equally significant — removing mass from the exhaust system lowers the centre of gravity and reduces unsprung and rotating mass, making the motorcycle more agile under braking and more precise on turn-in. This system is designed exclusively for closed-circuit competition use and carries no road homologation.
Fitment and Compatibility
This system is designed to fit the following motorcycle:
- BMW S1000RR K46 — model years 2010, 2011, 2012, 2013 and 2014
The lambda connection preserves compatibility with the stock ECU sensing arrangement. When removing the passenger footpegs, an optional mounting bracket is available to ensure a secure, rattle-free exhaust installation.
