YT IZZO CORE 4 REVIEW - A SHORT TRAVEL TRAIL BIKE WITH A GRAVITY ATTITUDE - Mountain Bike Action Magazine

May 2023 · Ron Koch

This short-travel bike takes some cues from the long-travel models that YT is known for, but has an entirely new set of design parameters: being light and efficient enough to be fun anywhere on the mountain, uphill or down.

Review: YT Izzo Core 4

Jan 2023 · Robert Johnston

Likening the Izzo to a Katana was so unbelievably spot on. It’s agile, responsive and fast, but still packs enough strength in its reserves...

Highs
  • Excellent pedaling

  • Very smart spec

  • More capable than you’d expect

  • Serious fun

Lows
  • Not ultra sensitive

Highs
  • Fast and fun on the right tracks, the Izzo begs for another lap
