Reminiscent of the iconic cone pipes once used exclusively by factory racing teams, the Factory Fatty embodies top-tier craftsmanship and material quality. It is specifically designed to broaden and smooth out your engine's power curve while delivering robust performance gains across the entire RPM range—giving your machine more low-end grunt, a stronger mid-range pull, and significantly increased over-rev capability.\u003c\/p\u003e\n\u003cp\u003eEngineered for maximum weight savings and optimized flow, FMF constructs the main body of this expansion chamber using a lighter 20-gauge steel, while employing a more rugged 19-gauge steel at the header portion to withstand roost and impact damage. Every seam is meticulously hand-pounded to guarantee ultra-smooth internal flow transitions. No matter what style of off-road riding or track racing your young rider tackles, the Factory Fatty provides the raw power and throttle tractability needed to lead the pack.\u003c\/p\u003e\n\u003ch3\u003eTop Features: FMF Factory Fatty Pipe\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eComprehensive Power Gains:\u003c\/strong\u003e Maximizes performance throughout the entire powerband, bolstering low-end torque, mid-range punch, and top-end over-rev.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eHand-Pounded Flow Seams:\u003c\/strong\u003e Welded and finished by hand to eliminate internal lips and step-offs, ensuring uninhibited exhaust gas scavenging.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDual-Gauge Steel Construction:\u003c\/strong\u003e Lighter 20-gauge steel body optimizes resonance and sheds weight, while a heavy-duty 19-gauge header resists rock and track debris.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWorks-Pipe Aesthetics:\u003c\/strong\u003e Features a raw, unplated finish with visible weld tracks that delivers a true factory racing look right out of the box.\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;\"\u003e2006-2016\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e85 SX\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;\"\u003e2017\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e85 SX (17\/14)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2008-2009\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e85 XC\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;\"\u003e2007-2012\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e105 SX\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2007-2012\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003eKTM\u003c\/td\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e105 XC\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: Does the Factory Fatty pipe require a specific type of maintenance due to its bare metal finish?\u003c\/strong\u003e\u003cbr\u003eA: Yes, because it has a raw, unplated finish to maximize tuning resonance, it will rust if left wet or dirty. After washing your bike, spray the pipe down with a light penetrating oil or anti-corrosion spray (like WD-40 or Maxima MPPL) and wipe off any excess to keep it looking factory fresh.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Can I use my stock OEM KTM silencer with this FMF expansion chamber pipe?\u003c\/strong\u003e\u003cbr\u003eA: Yes, the 025090 Factory Fatty is engineered to swap directly with your stock exhaust components. It will mount up to either your OEM silencer or any FMF slip-on silencer engineered for these exact machine models.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing a raw raw-finish race pipe, avoid handling the expansion chamber with your bare, oily hands right before starting the bike for the first time. The oil from your skin can bake permanently into the raw steel when it gets hot, causing uneven dark spots. Wipe the entire pipe down with contact cleaner or rubbing alcohol using a clean microfiber cloth after it is mounted and before you kick it over.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eRecommended Pairings:\u003c\/strong\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/new-ktm-85-sx-performance-upgrades-engine-mods-accessories-moto-house-mx\"\u003eKTM 85 SX Performance Parts \u0026amp; Upgrades\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/ktm-2-stroke-dirt-bikes-performance-parts-accessories-moto-house-mx\"\u003eKTM 2-Stroke Performance Parts\u003c\/a\u003e\u003cbr\u003eo \u003ca href=\"https:\/\/motohousemx.com\/collections\/premium-motorcycle-chemicals-brake-fluid-bike-wash-coolant-chain-lubes\"\u003eMotorcycle Chemicals\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
