  • We have designed triple trees that can be used with 50-55 inverted forks from metric sport bikes like GSXR (not included). Zero degree rake and stock offset
  • Recommended length of the fork legs is 29” to achieve 31” effective fork length.
  •  – be it canyon carving, track days and racing.
  • Fork leg spacing is set to GSXR width center on center fork legs so wheels and brake rotors etc. can transfer over. Check compatible rotor sizes
  • Fork stop on frame neck and other components may need minor modifications.
  • Not compatible with headlights mounted on OEM top triple tree
  • Aluminum parts have been machined from 6061-T6. Hard anodized for smooth and best UV stability to prevent discoloration of exposed parts
  • The 1” neck stem has been machined from 4140 steel and plated for superior strength and corrosion protection; Hardware set is made of 304 stainless steel
  • Ample clamping area to provide maximum strength .
  • Our Triple-Tree Kit was designed in the USA. All our products undergo a secondary domestic quality control process before they are shipped.
