Every bolt in the 34-piece set is CNC-turned to exact tolerances and finished with a durable anodised coating — the kind of detail that separates a properly prepared S1000RR from the rest of the pitlane.\u003c\/p\u003e\u003ch2\u003eKey Features\u003c\/h2\u003e\u003cul\u003e\n\u003cli\u003eErgal 7075 aluminium construction: up to 60% lighter than equivalent steel fasteners, reducing unsprung and overall mass where it counts.\u003c\/li\u003e\n\u003cli\u003eFull CNC precision machining ensures perfect fitment at every engine mounting point across the K46 chassis.\u003c\/li\u003e\n\u003cli\u003eHard anodised finish resists corrosion, heat cycles and fuel contamination while adding a clean racing aesthetic.\u003c\/li\u003e\n\u003cli\u003eComprehensive 34-piece set covers all relevant engine fastening positions in a single kit — no hunting for individual bolts.\u003c\/li\u003e\n\u003cli\u003eAvailable in five anodised colours — black, red, gold, silver and cobalt — to match or contrast your S1000RR's livery.\u003c\/li\u003e\n\u003cli\u003eDirect OEM replacement geometry; no modification required for fitment on 2015–2018 K46 models.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eAerospace Material, Track-Ready Execution\u003c\/h2\u003e\u003cp\u003eErgal 7075 is the same aluminium alloy used in aircraft structural components and high-end racing chassis parts. Its exceptional strength-to-weight ratio means LighTech can machine these bolts to the same clamping performance as steel while stripping meaningful grams from the engine area. The CNC process removes all variability: thread form, head geometry and shank diameter are held to tight tolerances on every single piece, so installation is clean and torque values behave predictably.\u003c\/p\u003e\u003cp\u003eThe anodised finish is not merely cosmetic. It forms a hard oxide layer directly within the aluminium surface, protecting against the thermal cycling, vibration and occasional oil or brake fluid contact that engine fasteners routinely experience. The result is a set of bolts that look as sharp after a full season of track days as they did on the day of fitting.\u003c\/p\u003e\u003ch2\u003ePart Numbers by Colour\u003c\/h2\u003e\u003cp\u003eEach colour variant carries its own LighTech part number for straightforward re-ordering:\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eBlack — 5B1MNER\u003c\/li\u003e\n\u003cli\u003eGold — 5B1MORO\u003c\/li\u003e\n\u003cli\u003eRed — 5B1MROS\u003c\/li\u003e\n\u003cli\u003eSilver — 5B1MSIL\u003c\/li\u003e\n\u003cli\u003eCobalt — 5B1MCOB\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch2\u003eFitment \u0026amp; Compatibility\u003c\/h2\u003e\u003cul\u003e\u003cli\u003eBMW S1000RR K46 (2015–2018)\u003c\/li\u003e\u003c\/ul\u003e\u003cp\u003eThe kit covers all relevant engine mounting positions for the K46 generation.
