If you're serious about finding the podium, you know that stock exhaust and intake systems are designed for the masses, not the racers. Moto-House MX understands that real performance starts with a strong base and improves the bike step by step. This Power-Up Performance Package provides the Racing Performance necessary to pull the holeshot and maintain a lead through the checkered flag. We can always add more parts later, but we have to start with a solid base package that we can expand on.\u003c\/p\u003e\n\n\u003cp\u003eEngineering for an 85cc machine requires a delicate balance of weight savings and precision engineering to optimize power delivery. By combining the hand-welded, stamped carbon steel Pro Circuit Works Pipe with the advanced VFORCE4R Reed Valve system, we've increased the combined reed tip area by 10.5% for superior airflow. Paired with a Twin Air dual-stage filter, this kit allows the engine to breathe with maximum efficiency. Utilizing TIG and MIG welding for durability and a specialized carbon fiber lay-up in the reeds, this setup turns high-revving 85s into surgical racing tools with a rugged, authoritative exhaust note.\u003c\/p\u003e\n\n\u003ch3\u003eTop Features: Moto-House MX Power-Up Performance Kit\u003c\/h3\u003e\n\n\u003cul\u003e\n\t\u003cli\u003e\n\u003cstrong\u003ePro Circuit Works Pipe:\u003c\/strong\u003e Hand-welded, stamped carbon steel construction that increases horsepower and torque across the entire RPM range.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003ePro Circuit R-304 Silencer:\u003c\/strong\u003e Features a 6061 T6 brushed aluminum body and 304 stainless steel intake tube for a lightweight, factory-spec finish.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eVFORCE4R Reed System:\u003c\/strong\u003e Features an airfoil cage shape and pre-curved carbon fiber petals for a better seal and increased air velocity.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eTwin Air Standard Filter:\u003c\/strong\u003e The industry standard in filtration, featuring a dual-foam design to maximize airflow while stopping all debris.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eIncreased Airflow:\u003c\/strong\u003e 10.5% increase in reed tip area combined with an aerodynamic central wing for instant throttle response.\u003c\/li\u003e\n\t\u003cli\u003e\n\u003cstrong\u003eMade in the USA:\u003c\/strong\u003e Every major component in this performance stage—Pro Circuit and VFORCE—is proudly manufactured in the United States.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003cp\u003e\u003cstrong\u003eExpert Pro-Tip:\u003c\/strong\u003e To keep your Power-Up kit performing at its peak, clean your Twin Air filter after every ride and check the R-304 silencer packing every 15 hours of hard racing.\u003c\/p\u003e\n\n\u003ch3\u003eFitment List\u003c\/h3\u003e\n\n\u003ctable border=\"1\" cellpadding=\"8\" cellspacing=\"0\" style=\"border-collapse:collapse; width:100%\"\u003e\n\t\u003cthead\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003cth\u003eYear Range\u003c\/th\u003e\n\t\t\t\u003cth\u003eVehicle Brand\u003c\/th\u003e\n\t\t\t\u003cth\u003eVehicle Model \u0026amp; Size\u003c\/th\u003e\n\t\t\u003c\/tr\u003e\n\t\u003c\/thead\u003e\n\t\u003ctbody\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003e2025 - 2026\u003c\/td\u003e\n\t\t\t\u003ctd\u003eKTM\u003c\/td\u003e\n\t\t\t\u003ctd\u003e85 SX (17\/14 \u0026amp; 19\/16)\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003e2025 - 2026\u003c\/td\u003e\n\t\t\t\u003ctd\u003eHusqvarna\u003c\/td\u003e\n\t\t\t\u003ctd\u003eTC 85 (17\/14 \u0026amp; 19\/16)\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\t\u003ctr\u003e\n\t\t\t\u003ctd\u003e2025 - 2026\u003c\/td\u003e\n\t\t\t\u003ctd\u003eGas Gas\u003c\/td\u003e\n\t\t\t\u003ctd\u003eMC 85 (17\/14 \u0026amp; 19\/16)\u003c\/td\u003e\n\t\t\u003c\/tr\u003e\n\t\u003c\/tbody\u003e\n\u003c\/table\u003e\n\n\u003ch3\u003eFrequently Asked Questions\u003c\/h3\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Is this kit a better value than buying parts individually?\u003c\/strong\u003e\u003cbr\u003e\nA: Yes, the Moto-House MX Power-Up Package is curated to ensure all components work in harmony, providing a better power curve than mismatched aftermarket parts.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: Do I need to modify the airbox to fit the Twin Air filter?\u003c\/strong\u003e\u003cbr\u003e\nA: No, this is a Standard Air Filter that fits your 2025-2026 OEM filter cage perfectly while offering superior protection.\u003c\/p\u003e\n\n\u003cp\u003e\u003cstrong\u003eQ: How do the VFORCE4R reeds improve durability?\u003c\/strong\u003e\u003cbr\u003e\nA: The V4R85A uses long reed stops to progressively slow petal tip velocity, which significantly extends the life of the carbon fiber petals under racing conditions.\u003c\/p\u003e\n\n\u003cp\u003eThis is your first step in improving the power delivery of your machine.
