When every gram and every detail counts, the LighTech swingarm axle nut for the BMW S1000RR K46 and K67 is the upgrade that quietly earns its place on both road and track. Machined from aerospace-grade Ergal 7075 aluminium and available in five anodised finishes, it delivers a factory-precise fit that inspires confidence mile after mile — and looks exceptional doing it.
Key Features
- Ergal 7075 aluminium construction — the same alloy trusted in aerospace for an outstanding strength-to-weight ratio
- CNC-precision machined to exact tolerances, ensuring a flush, rattle-free fit that stays secure under hard acceleration and braking
- Hard anodised surface finish provides reliable corrosion resistance and a durable, race-ready appearance
- Rated to a maximum tightening torque of 120 Nm, meeting the demands of sustained track use
- Available in black, blue, red, gold and silver to coordinate with your S1000RR's livery
- Direct replacement for both K46 (2009–2018) and K67 (2019–2026) chassis generations
Precision Engineering for the Long Haul
LighTech has built its reputation by applying motorsport manufacturing standards to every component it produces, and the D004 swingarm axle nut is no exception. The M18x1.5 thread is cut to micron-level precision so the nut seats evenly and torques down cleanly without any tendency to gall or seize — a detail that makes routine swingarm removal and reinstallation a far more pleasant experience across the lifetime of the bike. The 29 mm diameter and 14 mm height profile are dimensionally identical to the OEM specification, so there is no fettling, no shimming and no guesswork involved at installation.
Road and Track Performance
The appeal of the D004 goes beyond aesthetics. By replacing a steel factory nut with an Ergal 7075 unit, you strip a meaningful amount of unsprung rotational mass from the rear end — a change that subtly sharpens the S1000RR's already razor-edged handling response. The anodised finish is robust enough to survive the repeated heat cycles, road grime and chain lubricant exposure that any working sportsbike encounters, making this a lasting upgrade rather than a cosmetic one that needs babying.
