Widely recognized as the ultimate slip-on upgrade for mini-motocross racers, the Shorty design features a shortened canister length that optimizes exhaust gas backpressure. This structural profile delivers instant, aggressive bottom-end throttle response and massive mid-range acceleration, helping young racers pull holeshots and clear obstacles straight out of tight corners.\u003c\/p\u003e\n\u003cp\u003eConstructed out of lightweight 6061-T6 aerospace aluminum with a clean, brushed exterior finish, this ultra-light canister significantly reduces rear chassis weight over stock mufflers. The internal core assembly utilizes exclusive E-glass pillow packing to control sound waves while maximizing internal exhaust velocity. Completed with high-strength stainless steel intake pipes, double-walled mounting brackets, and structural Allen-head screws, maintenance and repacking are exceptionally straightforward.\u003c\/p\u003e\n\u003ch3\u003eTop Features: Pro Circuit R-304 Shorty Silencer\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eShorty Canister Profile:\u003c\/strong\u003e Compressed body layout optimizes power delivery down low, perfect for immediate acceleration out of corners.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLightweight Materials:\u003c\/strong\u003e Premium 6061-T6 brushed aluminum canister combined with a rugged stainless steel inlet pipe and end cap for maximum durability.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eE-Glass Pillow Packing:\u003c\/strong\u003e Proprietary packing configuration maximizes structural longevity and guarantees superior dampening efficiency.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSimple Disassembly:\u003c\/strong\u003e High-grade steel Allen-head fasteners enable rapid packing replacement without drilling out structural rivets.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003cp\u003e\u003cem\u003ePlease review the detailed compatibility data below to ensure an exact fitment match for your motorcycle before finalizing your purchase.\u003c\/em\u003e\u003c\/p\u003e\n\u003ch2\u003eFitment List\u003c\/h2\u003e\n\u003ctable style=\"width: 100%; border-collapse: collapse; border: 1px solid #e0e0e0; margin-top: 15px; margin-bottom: 15px;\"\u003e\n\u003cthead\u003e\n\u003ctr style=\"background-color: #f7f7f7;\"\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eYear Range\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Brand\u003c\/th\u003e\n\u003cth style=\"border: 1px solid #e0e0e0; padding: 12px; text-align: left; font-weight: bold; color: #333333;\"\u003eVehicle Model \u0026amp; Sub-Model\u003c\/th\u003e\n\u003c\/tr\u003e\n\u003c\/thead\u003e\n\u003ctbody\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2022-2025\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKawasaki\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKX112\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2001-2025\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKawasaki\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKX85\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e1998-2009, 2011-2021\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKawasaki\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKX100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2010\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKawasaki\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKX100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2003-2005\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eSuzuki\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eRM100\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr style=\"background-color: #f9f9f9;\"\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e1998-2018\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKawasaki\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKX80\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: What is the sound performance profile of the R-304 Shorty compared to the standard 304 silencer?\u003c\/strong\u003e\u003cbr\u003eA: The R-304 Shorty features a shorter canister body, which results in a slightly louder, crisp exhaust note with a significant emphasis on immediate low-to-mid range power generation. The standard 304 silencer offers a marginally quieter footprint and spreads performance more evenly across the top end.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How often do I need to repack the internal E-glass pillow packing in this shorty model?\u003c\/strong\u003e\u003cbr\u003eA: For two-stroke track machinery running at sustained high RPMs, Pro Circuit recommends servicing the silencer packing every 10 to 15 operating hours. Swapping worn packing elements restores backpressure balance, preserves optimal engine performance, and shields the aluminum sleeve from high thermal wear.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When seating your fresh silencer to your expansion chamber pipe joint, avoid utilizing generic hardware store silicone. Grab high-temperature RTV silicone sealant to establish an air-tight, absolute seal around the piping sleeve interface. A leaking exhaust collar allows raw ambient oxygen to mix with hot exhaust waves, resulting in erratic jetting performance, messy oil splatter, and noticeable throttle response delays.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/kawasaki-kx85-kx100-kx112-performance-parts-accessories-moto-house-mx\"\u003eKawasaki KX85 \/ KX100 \/ KX112 Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/pro-circuit-2-stroke-exhaust-pipes-and-silencers-moto-house-mx\"\u003ePro Circuit 2-Stroke Exhaust Collection\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003eHigh-Temp Seals \u0026amp; Chemicals\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
