Yamaha YZF-R9 — Extension Support Kit (EXT-RS) Not a Bigger Tank Pad. A Different Kind of Support. The HARMONIZE EXT-R9 RS is a one-piece 3D rider support and tank grip interface for the 2025–2026 Yamaha YZF-R9, built with an extended curved support profile. Conventional tank grips add friction to an existing flat surface. The EXT-RS goes further, adding a raised, contoured support point with extended coverage exactly where the rider's thigh meets the tank. Its three-dimensional TPU structure gives the lower body a defined surface to brace against, while a high-grip surface texture helps maintain consistent contact through that surface. The result isn't just more grip — it's a more functional connection between rider and motorcycle. An Extended Profile for Riders Who Need More Coverage The EXT-RS uses a larger, curved-extension footprint compared to the standard EXT profile — more surface area for the knee and thigh to brace against, shaped to follow the contour of the tank through a wider range of leg position. Because this profile extends further across the tank than a standard flat or curved pad, it's built as a standalone support component rather than a layer designed to sit alongside other tank grips. If your R9 already has aftermarket tank pads installed, check the coverage area before adding the EXT-RS, since the extended shape is designed to be the primary contact surface rather than an add-on to existing grip material. Built Around the Rider Contact Point Heavy trail braking into a corner, hard lean angle, and aggressive throttle on exit all place real load through a rider's lower body — and on a platform built from R-series sportbike DNA, that load happens often. A flat tank pad can help reduce sliding, but it doesn't change the shape or size of the contact area itself. The EXT-RS introduces an extended physical contour at that point. Instead of relying entirely on friction across a small surface, you get a wider support area to press your knee and thigh against — creating a more stable lower-body reference point and reducing how much you need to brace through your arms and the handlebars. Developed around the R9's tank geometry and riding posture, the EXT-RS integrates support and grip into one compact component, without a modular mounting system or interchangeable hardware. One Structure. Two Functions. The extended curved profile provides physical support across a wider contact zone. The integrated high-grip texture helps you maintain contact with that profile. Both functions are built into one continuous TPU component — no separate grip layer, no interchangeable extension, no additional mounting base to assemble. Dry-fit the component, confirm its position, and install it as one complete unit. What Makes the EXT-R9 RS Different Extended Curved Support ProfileA larger contact footprint than a standard flat or curved pad, giving your thigh more surface to brace against through a wider range of leg position. High-Grip Surface TextureAn integrated grip pattern helps maintain knee and thigh contact under braking, cornering, and acceleration — street or track. One-Piece TPU ConstructionThe structural profile and textured contact surface are manufactured as a single continuous component, for a clean, uncomplicated installation. Precision Fit for Yamaha GeometryDesigned specifically for the R9's tank shape and riding posture — not a generic profile adapted after the fact. Defined Lower-Body SupportGives you a wider, consistent surface to brace against, helping your legs contribute more to body positioning and stability. Pre-Applied 3M™ VHB™ AdhesiveInstalls without drilling, brackets, a separate mounting base, or special tools. Why It Matters on the YZF-R9 The R9 places real demands on rider positioning through trail braking, corner transitions, and hard acceleration. The EXT-RS creates a wider, more defined interface between your lower body and the tank than a standard-profile pad — the extended contour provides more support surface, and the high-grip texture helps you maintain contact with it. Together, these give you a more usable support point than a flat grip pad alone, without changing the performance-focused character of the bike.

The surface must be completely dry and free of water, dust, oil, wax, and residue. If necessary, carefully warm the tank surface to approximately 25–30°C (77–86°F) using a hair dryer or heat gun on a low setting. Do not overheat the painted surface. Clean and dry your hands before handling the component or adhesive. Dry-fit the component and confirm its position before removing the adhesive liner — check clearance against any existing tank grips first. Gradually peel away the liner while pressing the component into position. Apply firm, even pressure across the complete mounting surface to ensure full contact. Allow the adhesive to set for at least 12 hours. Avoid riding the motorcycle or exposing the installation area to water or moisture during this period.
