LighTech Chain Tensioner BMW S1000RR K46 (2009-2018) TEBM002

Machined from solid Ergal 7075 billet aluminium, the LighTech TEBM002 chain tensioner is a direct upgrade over the factory unit for the BMW S1000RR K46 — delivering a level of precision, rigidity and material quality that the OEM part simply cannot match. Whether you are chasing lap times on track or running a tight, efficient drivetrain on demanding roads, this is the component your swingarm deserves.

Key Features

• CNC-machined from solid Ergal 7075 high-strength aluminium alloy — exceptionally light yet far more rigid and durable than stock steel or cast components.
• External screw adjustment allows rapid, millimetre-accurate chain tensioning without removing the wheel — an invaluable advantage during race weekends or tyre changes.
• Laser-engraved graduated scale on each adjuster ensures both sides can be set to an identical position, preventing axle misalignment and uneven chain wear.
• Engineered to withstand the dynamic loading of high-performance track use, maintaining consistent gearing settings under the demands of repeated acceleration and braking.
• Supplied as a complete left and right pair, ready to fit without additional hardware.
• Compatible optional fork receiver kit FTEBM002 available separately for a full precision fitment solution.

Build Quality and Premium Materials

LighTech's decision to spec Ergal 7075 — the same aluminium alloy used in aerospace and motorsport structural components — sets the TEBM002 apart from budget aftermarket alternatives. The alloy offers a tensile strength significantly greater than the more common 6061 grade, which translates to chain adjusters that hold their set position reliably under load rather than creeping under the vibration and stress of a high-revving inline-four. The precision CNC milling process guarantees exact geometry on every unit, while the anodised finish adds corrosion resistance and a purposeful appearance in your choice of colour.

Performance on Road and Track

Accurate chain tension is one of the most overlooked factors in drivetrain efficiency and rear suspension behaviour. Too loose, and power is lost to chain slap and inconsistent drive; too tight, and you add unnecessary load to the swingarm bearings and output shaft. The TEBM002's laser-engraved scale makes it straightforward to set both sides symmetrically in moments — a task that can otherwise eat into valuable preparation time at a trackday. For road riders who adjust their chain regularly, the external screw mechanism removes the guesswork entirely.

Fitment and Compatibility

This chain tensioner is designed and manufactured specifically for the BMW S1000RR K46, covering all model years from 2009 through to 2018. It is not a universal part — the precision fit to this chassis is central to its performance advantage. If you are unsure whether your specific build year falls within this range, please contact the Inter-Pace team before ordering.
