The K-Tech adjustable fork spring perches are a pair of internal spring seats for Showa 49 mm forks fitted with 475 mm springs. They replace the original perches and allow spring preload to be adjusted for motocross (MX) and supercross (SX) suspension set-ups.


Features



  • Allows preload to be reduced below the original fork’s fixed setting.

  • Oil-flow design is intended to improve bottoming resistance in MX and SX use.

  • Replaces the original plastic perches with aluminium components.

  • Coated guide bushes provide smoother action.


Specifications



  • Fork diameter: 49 mm

  • Required spring length: 475 mm

  • Original fork preload at full extension: 5 mm; not reducible with the original perches

  • Perch material: aluminium

  • Guide bush coating: PTFE (Teflon)

  • Quantity: one pair

Vehicle Fitments


Compatibility depends on the motorcycle having Showa 49 mm forks with 475 mm springs. Check the installed fork internals and spring length before ordering, particularly if the springs or cartridges have been changed. The separate K-Tech 111-300-505 perches are specified for 500 mm springs and should not be substituted without checking spring length.
