FMF 021051 Fatty Pipe Exhaust for CR125 2005-2007

The FMF Racing Factory Fatty Pipe is a premium two-stroke expansion chamber designed to deliver increased power and performance for Honda CR125 motorcycles. Engineered with the same cone geometry as FMF's legendary Fatty pipe, this exhaust system optimizes exhaust resonance for improved throttle response and broad powerband gains.

Advanced Dual-Gauge Construction:

• Header section constructed from heavy-duty 19-gauge US steel for maximum strength and durability in high-stress areas
• Body and rear cone sections use lighter 20-gauge steel to reduce overall weight without sacrificing performance
• Thinner body material provides a slight power increase through more efficient heat resonance characteristics
• Seams are hand-pounded after stamping for superior fitment and longevity

Features:

• Raw, unplated, oiled finish reduces manufacturing costs while maintaining excellent corrosion resistance
• Proven cone-shaped expansion chamber design maximizes two-stroke exhaust scavenging
• Direct bolt-on replacement for stock exhaust system
• Made in the USA with premium American steel

This Factory Fatty pipe delivers the performance advantage that has made FMF Racing the choice of professional motocross and off-road racers worldwide. The strategic use of dual-gauge steel construction provides the ideal balance of strength, weight savings, and power output.
