Product Details

The Factory Fatty is our top-tier 2-stroke expansion chamber, built with hand-cone construction in our Southern California factory. The Factory designation means each pipe is hand-rolled and TIG-welded for a true factory-replica race pipe. Broadens the powerband across the entire RPM range with improved throttle response.

  • Hand-cone, hand-rolled construction — built in California
  • Tru-Flo stamping process for exact fit
  • Broad powerband with strong over-rev
  • Hand-TIG-welded seams
  • Includes O-rings

Fitment: 2-stroke bike specific — fits the following models:

  • Beta 250RR (2020-2026)
  • Beta 300RR (2020-2026)
  • Beta 300RX (2021-2024)

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.
