Moto-House MX Power-Up Kit Pro Circuit VFORCE4R Twin Air 2025-2026 KTM 85 SX TC85 MC85

Engineering a Podium Contender From the Ground Up

The 2025-2026 KTM 85 SX, Husqvarna TC 85, and GasGas MC 85 are already weapons in the 85cc class, but even a proven winner has room to grow. 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.

Engineering 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.

Frequently Asked Questions

Q: Is this kit a better value than buying parts individually?
A: 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.
