LighTech Aluminium Engine Bolt Kit for Kawasaki ZX-10R/RR (2021–2026) – ENGKA001

Every gram matters on a ZX-10R/RR, and the LighTech ENGKA001 aluminium engine bolt kit is one of the most satisfying upgrades you can fit in an afternoon. Twenty-three CNC-machined Ergal 7075 bolts replace the heavy OEM steel hardware across all key engine mounting points, shaving meaningful unsprung and chassis weight while giving the motor bay a clean, purposeful racing aesthetic that lasts ride after ride.

Key Features

• Ergal 7075 aluminium construction — up to 60% lighter than equivalent steel bolts without sacrificing structural integrity under sustained high-rpm load
• CNC-machined to exacting tolerances for perfect thread engagement and a flush, professional fit at every fastener point
• Hard anodised finish provides genuine corrosion resistance and locks in your chosen racing colour for the long term
• Complete 23-piece set covers all relevant engine fastener positions on the ZX-10R and ZX-10RR — no hunting for individual bolts
• Available in five anodised colours — black, red, gold, silver and cobalt — so the kit can complement your bike's livery exactly
• Suits both the standard ZX-10R and the homologation-special ZX-10RR across the full 2021–2026 production run

Build Quality and Finish

LighTech machines this kit from Ergal 7075, the same high-tensile aluminium alloy used across aerospace and top-level motorsport applications. The alloy's exceptional strength-to-weight ratio means the bolts handle the thermal cycling and vibration inherent to a superbike engine without creeping or fatiguing. The anodising is applied after machining, sealing the surface against moisture and track chemicals while adding a depth of colour that bare or painted aluminium simply cannot match. The result is a set of bolts that looks as considered as the rest of a well-built ZX-10R.

Track and Road Use

Whether you are chasing lap times at a club day or simply want your ZX-10R to reflect the care you put into its preparation, the ENGKA001 kit delivers on both fronts. The weight reduction is real and repeatable — 23 bolts replaced across the engine means the saving accumulates quickly. On track, less rotating and reciprocating mass contributes to sharper throttle response and marginally reduced inertia. On the road, the visual upgrade is the headline: a set of matched anodised bolts transforms the engine bay from a utilitarian collection of black fasteners into a cohesive, colour-coded detail that rewards a close look.
