The Throttle Tube by Factory Image Racing (FIR) is an OEM replacement part specifically designed for Honda CR80R, CR80RB Expert, CR85R, and CR85RB Expert models. This throttle tube is crafted from a nylon composite material, which offers several advantages over aluminum tubes, including: Durability: The nylon composite material ensures that the tube will not scar the handlebars, unlike aluminum alternatives. Versatility: The pop-out end caps are ideal for off-road applications, making it easy to use with bar-end-type handguards. Grip Security: Molded ridges on the tube help to secure the grips firmly in place. Ease of Installation: The one-piece tube and reel design fits directly into the stock throttle housing without the grip.
