Factory chain guides rely on thin aluminum outer cages with soft plastic inserts. In rocky terrain, ruts, or log crossings, an impact will bend the OEM aluminum plate inward, jamming the drive chain into the rear sprocket or ripping the welded mounting tabs clean off the swingarm.\u003c\/p\u003e\n\u003cp data-path-to-node=\"2\"\u003eEngineered from TM Designworks' proprietary Return Memory System (RMS) polymer formula, this chain guide absorbs heavy direct rock strikes and flexes without bending, instantly snapping back to its original shape. The low-friction composite material is oil-impregnated to reduce chain surface drag, wear, and horsepower loss. Designed with an extended leading edge to guide the chain cleanly into the teeth of the rear sprocket, it features a replaceable lower wear pad to make long-term maintenance simple without replacing the entire guide body.\u003c\/p\u003e\n\u003ch4 data-path-to-node=\"3\"\u003eFeatures:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"4\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,0,0\"\u003e\u003cb data-path-to-node=\"4,0,0\" data-index-in-node=\"0\"\u003eReturn Memory Plastic:\u003c\/b\u003e Proprietary plastic formula flexes upon impact with rocks, stumps, and ruts, returning to shape without permanent deformation or bending.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,1,0\"\u003e\u003cb data-path-to-node=\"4,1,0\" data-index-in-node=\"0\"\u003eProtects Swingarm Tabs:\u003c\/b\u003e Absorbs and dissipates blunt impact energy, preventing bent or broken welded chain guide mounts on the swingarm.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,2,0\"\u003e\u003cb data-path-to-node=\"4,2,0\" data-index-in-node=\"0\"\u003eLow-Friction Additives:\u003c\/b\u003e Oil-impregnated polymer formula reduces chain friction, tooth drag, and drive-related horsepower loss.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,3,0\"\u003e\u003cb data-path-to-node=\"4,3,0\" data-index-in-node=\"0\"\u003eReplaceable Wear Pad:\u003c\/b\u003e Features an easily serviceable lower rubbing block so you can refresh the wear surface without purchasing an entirely new housing.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"4,4,0\"\u003e\u003cb data-path-to-node=\"4,4,0\" data-index-in-node=\"0\"\u003eExtended Protection Profile:\u003c\/b\u003e Longer leading edge guides the chain onto the rear sprocket during aggressive suspension compression and high-angle cornering.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"5\"\u003eWhat's in the Box:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"6\"\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,0,0\"\u003e1x TM Designworks Factory Edition Rear Chain Guide Body (Black)\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,1,0\"\u003e1x Pre-Installed Replaceable Wear Pad\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,2,0\"\u003eMounting Hardware \u0026amp; Bushings Kit\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"6,3,0\"\u003eInstallation Instructions\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4\u003eFitment:\u003c\/h4\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003ch4\u003e2025–2027 – Suzuki DR-Z4S\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e2025–2027 – Suzuki DR-Z4SM\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003ch4\u003e2000–2024 – Suzuki DR-Z400\u003c\/h4\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch4 data-path-to-node=\"7\"\u003eFitment Notes:\u003c\/h4\u003e\n\u003cul data-path-to-node=\"8\"\u003e\n\u003cli\u003e\n\u003cb data-path-to-node=\"8,2,0\" data-index-in-node=\"0\"\u003eSprocket Sizing:\u003c\/b\u003e Accommodates stock and oversized rear sprockets up to 47 teeth (larger sprockets may require minor clearance checks depending on chain length).\u003c\/li\u003e\n\u003cli\u003e\n\u003cmeta charset=\"utf-8\"\u003e\n\u003cp data-path-to-node=\"12\"\u003e\u003cb data-path-to-node=\"12\" data-index-in-node=\"0\"\u003eSwingarm Mount Insurance:\u003c\/b\u003e On the DR-Z400, the lower swingarm mounting tabs are relatively thin aluminum extrusions. When the stock metal chain guide hits a rock, it transfers 100% of the shear force straight into the front swingarm tab, often snapping the tab off at the weld. Repairing this requires skilled aluminum TIG welding. The TM Designworks polymer body acts as a shock buffer—it yields and deflects under rock impacts, isolating the swingarm mounts from destructive peak shear forces.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003cli\u003e\n\u003cp data-path-to-node=\"13\"\u003e\u003cb data-path-to-node=\"13\" data-index-in-node=\"0\"\u003eHardware Installation Tip:\u003c\/b\u003e When mounting the RCG-SY2-BK, use the included aluminum collar bushings in the mounting bolt recesses. Apply medium-strength blue threadlocker to each bolt and torque to Suzuki factory specification (typically 9 Nm \/ 80 in-lbs). Avoid over-torquing, which can crush the internal composite bushings. Check chain alignment by spinning the rear wheel on a stand to verify the chain runs centered down the internal channel.\u003c\/p\u003e\n\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/files\/Made_In_The_USA_24865b83-5069-42c1-b4bc-9e28ee4fe2cb.jpg?v=1719961954\" alt=\"\"\u003e\u003c\/p\u003e\n\u003cp\u003e \u003c\/p\u003e\n\u003cp\u003ePart Number: RCG-SY2-BK\u003cbr\u003e\u003cbr\u003e\u003c\/p\u003e","brand":"TM Designworks","offers":[{"title":"Default Title","offer_id":50699906482341,"sku":"TMDES-CHN-GUD-DRZ4- BLK","price":104.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0622\/5720\/1317\/files\/TM_Designworks_Chain_Guide_Suzuki_DR-Z_RCG-SY2-BK.png?v=1792976331","url":"https:\/\/www.tmbrmoto.com\/products\/tm-designworks-rear-chain-guide-suzuki-drz400-drz4s-rcg-sy2-bk","provider":"TMBR MOTO","version":"1.0","type":"link"}
