Product Description

The Pro Circuit 0721665 Works Pipe delivers exceptional horsepower and throttle response across the entire RPM range for your machine, engineered specifically to maximize performance for 2-stroke youth motocross applications. Precision-built to conform to the natural contours of your chassis, this high-performance expansion chamber provides optimal exhaust scavenging and power delivery.

Constructed from stamped AKDQ high-quality carbon steel with hand-welded and pounded seams, this pipe features an unplated, raw metal finish that gives your motorcycle an authentic factory race team appearance.

Frequently Asked Questions

Q: How do I maintain the raw unplated metal finish on this expansion chamber?
A: Because the pipe features a bare metal finish, apply a light coat of rust preventative oil (such as WD-40 or Maxima MPPL) after washing your motorcycle to protect the carbon steel from surface oxidation.

Q: Does this pipe include mounting hardware or seals?
A: This product includes the expansion chamber pipe itself (sold individually). You will reuse your factory mounting hardware, springs, and O-rings or replace them with fresh OEM-quality components during installation.

Expert Pro-Tip: When installing a new 2-stroke expansion chamber, leave all frame mounting bolts and manifold springs loose until every attachment point is aligned. Start by securing the CNC-machined flange at the cylinder port first, then work your way back to the frame rubber mounts and silencer junction to eliminate pre-load stress that can lead to premature pipe cracking.
