YZF-R9 Extension Support Kit (EXT-RSH)

Yamaha YZF-R9 — Extension Support Kit (EXT-RSH) Not a Bigger Tank Pad. A Different Kind of Support. The HARMONIZE EXT-R9 RSH is a one-piece 3D rider support and tank grip interface for the 2025–2026 Yamaha YZF-R9, built with an extended, raised support profile — the tallest structure in the EXT lineup. Conventional tank grips add friction to an existing flat surface. The EXT-RSH goes further, adding a raised, contoured support point with both extended coverage and additional height exactly where the rider's thigh meets the tank. Its three-dimensional TPU structure gives the lower body a pronounced 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. When the Standard Extended Profile Isn't Enough The EXT-RS gives you extended coverage. The EXT-RSH takes that same extended footprint and raises the profile height further — built for riders who want a more pronounced contact point to brace against, whether that's because of riding style, body position, or simply wanting more structure to press into under hard load. This is the most aggressive support profile in the EXT Series. Because both the coverage area and the height are increased beyond the standard EXT-RS, the EXT-RSH is built as a standalone support component and is not designed to sit alongside existing tank grip pads. If your R9 already has aftermarket grip material installed, plan on the EXT-RSH replacing that coverage area rather than layering on top of it. 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. A flat tank pad can help reduce sliding, but it doesn't change the shape, size, or height of the contact area itself. The EXT-RSH introduces a taller, extended physical contour at that point. Instead of relying entirely on friction across a shallow surface, you get a more substantial support structure to press your knee and thigh against — creating a firmer 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-RSH integrates support and grip into one compact component, without a modular mounting system or interchangeable hardware. One Structure. Two Functions. The raised, extended profile provides physical support with greater height and surface area than the standard EXT-RS. 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 RSH Different Raised Extended Support Profile The tallest, most pronounced profile in the EXT Series — more height and surface area than the standard EXT-RS, for riders who want a firmer contact structure to brace against. High-Grip Surface Texture An integrated grip pattern helps maintain knee and thigh contact under braking, cornering, and acceleration — street or track. One-Piece TPU Construction The structural profile and textured contact surface are manufactured as a single continuous component, for a clean, uncomplicated installation. Precision Fit for Yamaha Geometry Designed specifically for the R9's tank shape and riding posture — not a generic profile adapted after the fact. Maximum Lower-Body Engagement The added height gives your leg more structure to actively press against, shifting more load-bearing away from your arms and grip strength. Pre-Applied 3M™ VHB™ Adhesive Installs without drilling, brackets, a separate mounting base, or special tools. Why It Matters on the YZF-R9 Riders who've already tried a standard grip pad or the EXT-RS and want a more defined structure to load their body against are exactly who the EXT-RSH is built for. The added height gives you a firmer, more substantial contact point through trail braking, corner transitions, and hard acceleration — 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 — if you have existing tank grips installed, plan for removal 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.
