DescriptionThe whole story▼
Italian craftsmanship meets precision engineering in the Bonamici Racing CHAD09 chain tensioner, designed exclusively for the BMW S1000RR K67 from 2019 to 2026. CNC-machined from solid aluminium and finished in your choice of anodised colours, this is a component that earns its place on both track-day machines and road-going superbikes that demand the best.
Key Features
- CNC-machined aluminium construction delivers the strength and corrosion resistance expected of a genuine racing component.
- Micrometric adjustment positions allow precise, repeatable chain slack settings — critical for consistent drive and handling on the BMW S1000RR platform.
- Rigid swingarm mounting eliminates movement under load, keeping your chain adjustment exactly where you set it.
- Beautifully anodised finish available in five colours — red, blue, gold, black, and silver — so the tensioner complements any S1000RR livery.
- Supplied as a matched left and right pair for a complete, balanced installation requiring no modifications.
- 100% Made in Italy by Bonamici Racing, a marque synonymous with uncompromising quality in the racing accessories world.
Design, Finish and Heritage
Bonamici Racing has built its reputation on producing components that look as purposeful as they perform. The CHAD09 exemplifies this philosophy: the deep, even anodising on each colour variant is applied to an already-refined CNC profile, giving the tensioner an appearance that would not look out of place on a WorldSBK pit-lane bike. This is not an afterthought accessory — it is a considered upgrade that reflects the Italian brand's decades of motorsport involvement.
Performance and Precision
Chain tension is one of the most frequently overlooked variables in motorcycle setup, yet it has a direct effect on rear-wheel traction, drivetrain smoothness, and swingarm bearing life. The CHAD09's micrometric adjustment system makes it straightforward to dial in the exact slack recommended by BMW, and to verify and repeat that setting at every service interval. The rigid swingarm mount means there is no flex or creep between adjustments — the number you set is the number you get, lap after lap.
Fitment and Compatibility
The Bonamici Racing CHAD09 is engineered specifically for the BMW S1000RR K67 covering model years 2019 through 2026. The kit replaces both the left and right factory chain tensioner blocks as a direct fit, requiring no drilling, welding, or other modification to the swingarm.
