FMF Rev Pipe 2-Stroke — Yamaha YZ125/YZ125X

The Factory Fatty Rev pipe shifts the Fatty's powerband toward the middle and upper RPMs — built for riders who feel they're running out of power up top, want more time between shifts, and spend time in deep berms or sand. Hand-cone, hand-rolled, and TIG-welded.

• Hand-cone, hand-rolled construction
• Power-band shifted to mid and upper RPM
• Tuned for sand, deep berms, and big-bore 2-stroke top end
• Hand-TIG-welded seams
• Made in Southern California

This is a 2-stroke exhaust. It is engineered for the 2-stroke engine architecture above and physically will not fit a 4-stroke bike. Verify your engine type before purchase.
