Product Details

The PowerCore 4 HEX is the hexagonal-canister version of FMF's proven 4-stroke slip-on. The hex shape adds rigidity and a modern look while keeping the same straight-through, mid-range-focused tuning the PowerCore 4 is known for.

  • Hexagonal aluminum canister — added rigidity and modern look
  • Direct 4-stroke slip-on
  • Stainless endcaps and stinger
  • Tuned for mid-range gain over stock
  • Repackable

Fitment: 4-stroke bike specific — fits the following models:

  • Beta 350RR (2020-2026)
  • Beta 390RR (2020-2026)
  • Beta 430RR (2020-2026)
  • Beta 480RR (2020-2026)

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