LighTech Aluminium Engine Bolt Kit for Yamaha YZF-R1/M RN32, RN49, RN65 (2015-2026) 5Y1M

Few finishing touches define a race-prepared R1 quite like LighTech's Ergal 7075 engine bolt kit. Conceived in Italy with the same obsessive attention to detail that shapes top-level paddock culture, this 28-piece set replaces every major engine fastener on the Yamaha YZF-R1 and YZF-R1M (RN32, RN49, RN65, 2015–2026) with precision-machined, anodised aluminium hardware that is as visually arresting as it is functionally sound.

Key Features

• Ergal 7075 aerospace-grade aluminium — up to 60% lighter than steel with exceptional tensile strength for high-stress engine mounting points.
• CNC-machined to exacting tolerances for a perfect fit at every engine fixing location on the RN32, RN49 and RN65 chassis.
• Hard anodised finish delivers lasting corrosion resistance and a vivid, consistent colour that holds its depth through heat cycles and washing.
• Complete 28-piece set — every relevant engine bolt included, so there are no additional purchases needed and no mismatched hardware.
• Available in five distinct anodised colours to co-ordinate with your R1's livery or personal style.

Heritage, Finish and Design

LighTech built its reputation on the Italian racing scene before expanding into MotoGP and World Superbike paddocks. Every bolt in this kit reflects that lineage: the profiles are drawn directly from the OEM fixing geometry of the Yamaha YZF-R1 and R1M, then re-interpreted in Ergal 7075 — the same alloy specification used in aeronautical structures where the strength-to-weight ratio is non-negotiable. The hard anodising process penetrates the surface rather than sitting on top of it, meaning the colour is part of the material itself. Whether you select the understated drama of black (5Y1MNER), the warmth of gold (5Y1MORO), the aggression of red (5Y1MROS), the clean look of silver (5Y1MSIL) or the deep tone of cobalt (5Y1MCOB), the result is hardware that genuinely elevates the visual quality of the engine bay.

On the Road and on Track

The weight reduction offered by switching from standard steel fasteners to Ergal 7075 aluminium is modest in absolute terms but meaningful when combined with other lightweight components — and entirely free of compromise on a motorcycle used for both road and track days. The anodised surface resists the oil, heat and cleaning products that degrade painted or plated hardware over a full season, keeping the engine bay looking purposeful long after installation.
