LighTech Aluminium Engine Bolt Kit for Yamaha YZF-R6 RJ27 (2017–2026) – 29-Piece Ergal 7075 Set 6Y7M

Few details reveal a rider's eye for quality like an anodised aluminium engine bolt kit — and LighTech's 29-piece set for the Yamaha YZF-R6 RJ27 is where aerospace-grade engineering meets unmistakable racing aesthetics. Machined from Ergal 7075 aluminium, the same alloy trusted by the aviation industry, this kit delivers a meaningful reduction in unsprung mass alongside a finish that transforms the appearance of the engine bay.

Key Features

• Ergal 7075 aluminium construction: an aerospace-specification alloy that combines exceptional tensile strength with genuine weight savings over OEM steel fasteners
• CNC-machined to exacting tolerances, guaranteeing a precise, rattle-free fit at every engine mounting point on the RJ27
• Anodised surface treatment offers durable corrosion resistance and a consistent, competition-grade finish in five colour options
• Complete 29-piece set covering all principal engine fastener positions — no supplementary hardware required
• Equally at home on a track-day weapon or a street-legal R6 where visual detail matters as much as performance

Heritage, Design and Finish

LighTech has spent decades supplying aftermarket fastener systems to race teams and demanding road riders across Europe. That heritage is embedded in the 6Y7M kit: every bolt is individually CNC-turned from billet Ergal 7075 and then hard-anodised, producing a surface that resists both the thermal cycling of a high-revving inline-four and the aesthetic scrutiny of the paddock. The five available colours — black, red, gold, silver and cobalt — are not afterthoughts. Each anodised shade is consistent across the full set, so the engine bay presents a cohesive, intentional look rather than a patchwork of mismatched hardware.

Precision Engineering for the Track and Road

Ergal 7075 is not ordinary aluminium. Its silicon, magnesium and zinc content produce a material with a strength-to-weight ratio that rivals titanium at a more accessible price point. LighTech exploits this by machining the bolts to the same thread specifications as the factory fasteners, so installation requires no modification and no specialist tooling beyond what a competent home mechanic already owns. The result is a direct, confidence-inspiring swap that saves weight and elevates the visual standard of the motorcycle in a single session.
