LighTech Aluminium Engine Bolt Kit BMW S1000RR K46 (2015-2018) 5B1M

Precision-machined from Ergal 7075 aerospace-grade aluminium, the LighTech engine bolt kit for the BMW S1000RR K46 (2015–2018) delivers a level of build quality that stock fasteners simply cannot match. 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.

Key Features

• Ergal 7075 aluminium construction: up to 60% lighter than equivalent steel fasteners, reducing unsprung and overall mass where it counts.
• Full CNC precision machining ensures perfect fitment at every engine mounting point across the K46 chassis.
• Hard anodised finish resists corrosion, heat cycles and fuel contamination while adding a clean racing aesthetic.
• Comprehensive 34-piece set covers all relevant engine fastening positions in a single kit — no hunting for individual bolts.
• Available in five anodised colours — black, red, gold, silver and cobalt — to match or contrast your S1000RR's livery.
• Direct OEM replacement geometry; no modification required for fitment on 2015–2018 K46 models.

Aerospace Material, Track-Ready Execution

Ergal 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.

The 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.

Part Numbers by Colour

Each colour variant carries its own LighTech part number for straightforward re-ordering:

• Black — 5B1MNER
• Gold — 5B1MORO
• Red — 5B1MROS
• Silver — 5B1MSIL
• Cobalt — 5B1MCOB

Fitment & Compatibility

• BMW S1000RR K46 (2015–2018)

The kit covers all relevant engine mounting positions for the K46 generation. No additional hardware or modifications are required. Always torque fasteners to manufacturer specification using a calibrated torque wrench.
