Specifically engineered for the 85 SX and 105 SX platforms, the V-Force 3 is designed to dramatically improve throttle response and widen the powerband. By optimizing the airflow velocity entering the crankcase, this \u003cstrong\u003ereed valve set\u003c\/strong\u003e ensures that your engine achieves maximum efficiency throughout the entire RPM range, giving you the competitive edge on the track.\u003c\/p\u003e\n\u003cp\u003eThe V-Force 3 features a unique, screwless snap-together cage, which eliminates the risk of hardware coming loose and damaging your engine—a common concern with older reed valve designs. The symmetrical carbon fiber reed petals are identical for both sides of the cage, significantly simplifying maintenance and reducing long-term costs. The shaped reed tips work to accelerate the air-fuel mixture, providing the sharp, instant power delivery required for modern motocross.\u003c\/p\u003e\n\u003ch3\u003eTop Features: Moto Tassinari V-Force 3 Reed Valve\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSnap-Together Design:\u003c\/strong\u003e Innovative, screwless construction ensures maximum reliability and engine safety.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSymmetrical Reed Petals:\u003c\/strong\u003e Simplified maintenance using identical replacement petals for all sides of the cage.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eOptimized Airflow Velocity:\u003c\/strong\u003e Specifically shaped reed tips accelerate the air-fuel mixture for improved torque and throttle response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eCarbon Fiber\/Rubber Construction:\u003c\/strong\u003e Durable, lightweight materials designed to withstand the high-frequency vibrations of high-performance 2-stroke engines.\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;\"\u003e2003-2007\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;\"\u003e2003-2007\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;\"\u003e2005-2007\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 (19\/16)\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;\"\u003e2003-2004\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 BW (19\/16)\u003c\/td\u003e\n\u003c\/tr\u003e\n\u003ctr\u003e\n\u003ctd style=\"border: 1px solid #e0e0e0; padding: 10px; color: #555555;\"\u003e2003-2007\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\u003c\/tbody\u003e\n\u003c\/table\u003e\n\u003ch2\u003eFrequently Asked Questions\u003c\/h2\u003e\n\u003cp\u003e\u003cstrong\u003eQ: Will I need to re-jet my KTM after installing this?\u003c\/strong\u003e\u003cbr\u003eA: Yes. Because the V-Force 3 allows significantly more airflow than the stock cage, your bike will likely run lean if you don't adjust your jetting. We recommend testing with a slightly richer main jet and pilot circuit setting to achieve the correct air\/fuel ratio.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eQ: How can I tell when it is time to replace my reed petals?\u003c\/strong\u003e\u003cbr\u003eA: Inspect the petals every 15-20 hours. If you see light passing through the tips when held up to a light source, or if you notice any fraying or chipping on the edges of the petals, they should be replaced immediately to prevent power loss and potential engine damage.\u003c\/p\u003e\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e When installing the reed valve assembly, ensure your intake manifold is completely free of old gasket residue. Using a small amount of fuel-resistant gasket sealer (like Yamabond or ThreeBond) on the manifold flange ensures a perfect seal, preventing unwanted air leaks that can lead to high engine temperatures and poor idle stability.\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\"\u003ePremium Motorcycle Maintenance Supplies\u003c\/a\u003e\u003c\/p\u003e\n\u003cp\u003eAt Moto-House MX, we carry the best brands in motocross and off-road performance.
