DescriptionThe whole story▼
Achieving a precise chain slack setting on your BMW S1000RR K46 has never been this straightforward. The Bonamici Racing chain tensioner CHAD01 is CNC-machined from solid aluminium and mounts directly into the swingarm, giving you micrometric adjustment that makes chain maintenance a quick, repeatable job rather than a frustrating guess.
Key Features
- CNC-milled aluminium construction for lasting durability and resistance to the harshest track and road conditions
- Micrometric adjustment positions allow exact chain slack setting, improving drivetrain stability and overall performance
- Rigid swingarm mount guarantees the adjuster stays precisely where you set it — no creeping or slipping under load
- Direct-fit design for the BMW S1000RR K46 (2009-2018) requires zero modifications to the chassis
- Supplied as a matched left and right pair for a complete, balanced installation in a single session
- Available in red, blue, gold, black, and silver to complement your S1000RR's colour scheme
Built for Precision, Designed to Last
Bonamici Racing produce every component at their facility in Italy, and the CHAD01 chain tensioner is a clear expression of that philosophy. The solid aluminium billet is machined to tight tolerances, resulting in a part that slots into the K46 swingarm with no play and no compromise. Where standard adjusters rely on coarse increments, the micrometric scale built into the CHAD01 lets you dial in chain slack to the millimetre — critical on a bike with the S1000RR's power delivery and corner-exit aggression.
Simple Installation, Long-Term Reliability
The CHAD01 is engineered to replace the OEM chain tensioner without any drilling, tapping, or modification. Both the left and the right adjuster install using existing mounting points, so the job is well within reach for any competent home mechanic. Once fitted, the anodised finish resists corrosion from chain lube, road grime, and weather, keeping the part looking sharp across many seasons of use.
Fitment and Compatibility
The Bonamici Racing CHAD01 is designed exclusively for the BMW S1000RR K46 covering model years 2009 through 2018. It is not compatible with the later K67 generation (2019-onwards). Always confirm your frame code before ordering.
