Pro Circuit Works Pipe Exhaust 0761985 - KTM 85 SX 2018-2024

Product Description

The Pro Circuit Works Pipe delivers unmatched horsepower and torque gains across the entire rpm range for junior racers competing on the KTM 85 SX. Designed specifically for two-stroke mini competition, this expansion chamber provides immediate, crisp throttle response from the bottom-end pull up through peak over-rev.

Engineered from stamped AKDQ carbon steel, this pipe features hand-welded and pounded seams that follow the natural lines of the motorcycle frame. Reinforced mounting brackets and stinger sections eliminate stress cracking during hard racing, while the CNC-machined manifold flange provides a precise, leak-free exhaust port seal.

Frequently Asked Questions

Q: Does this Works Pipe fit both small wheel and big wheel models?
A: Yes, it is engineered to fit both the standard 17/14 wheel setup and the 19/16 Big Wheel version of the 2018-2024 KTM 85 SX.

Q: How do I care for the bare metal finish?
A: Because the metal is unplated, dry the pipe completely after washing the bike and apply a light coating of anti-corrosion spray or protective oil to the bare steel to prevent surface rust.

Expert Pro-Tip: Always install fresh copper exhaust O-rings and inspect the rubber manifold coupler before mounting your new expansion chamber. When tightening mounting tabs, leave all hardware hand-tight until the manifold flange and silencer joint are perfectly seated, then torque the fasteners to prevent unneeded stress on the mounting brackets.
