SC-Project SC1-S Slip-On Silencer BMW S1000RR K67 (2020-2022) B33B-124 – Euro 5 Approved

The SC1-S is the latest evolution in SC-Project's SC1 family — a slip-on silencer engineered from the ground up for high-performance superbikes. Constructed in either aerospace-grade titanium or hand-laid carbon fibre, it brings genuine racing-department material quality to road and track use on the BMW S1000RR K67, while carrying full Euro 5 road homologation.

Key Features

• Available in two premium finishes: titanium alloy body (B33B-124T) or carbon fibre body (B33B-124C) — both chosen for extreme heat resistance and minimal mass.
• Minimalist, race-derived silhouette with a modern aesthetic that complements the S1000RR's aggressive bodywork without compromise.
• Includes a dB killer and block system for a perfectly tuned exhaust note — compliant for road use, removable for track days.
• Plug-and-play fitment engineered specifically for the BMW S1000RR K67, requiring no modifications to the stock header or mounting points.
• Euro 5 road approved with EC and TÜV certification, making this a fully legal performance upgrade for street use.
• Weight saving of 0.6 kg over the standard silencer, directly improving the bike's agility and handling response.

Build Quality and Materials

SC-Project's choice of materials for the SC1-S reflects the same philosophy found in their MotoGP and WorldSBK programmes. The titanium variant delivers an exceptional strength-to-weight ratio with natural heat colouration that deepens over use — a living finish that marks every ride. The carbon fibre variant uses high-quality woven carbon with a clear lacquer finish, combining visual drama with outstanding thermal management. Both are finished with a carbon fibre heat shield, protecting the bodywork and rider while reinforcing the premium character of the unit. Every SC1-S is assembled with precision-fit springs and bolts for secure, rattle-free installation.

Performance on Road and Track

The SC1-S is a genuine dual-purpose exhaust upgrade. On the road, the dB killer keeps the exhaust note within legal limits while delivering a noticeably richer, more characterful tone than the stock system. Remove the dB killer for circuit sessions and the SC1-S opens up to the sharp, focused sound that SC-Project is renowned for in world-level motorsport. The 0.6 kg weight reduction is felt immediately — less rotating and unsprung mass contributes to sharper turn-in and more responsive handling, particularly in fast direction changes where the S1000RR is already exceptional.
