Wilbers Zero Friction Progressive Fork Springs (-30mm low) / F750GS '18-On
Please see our lowering shocks, either ESA or Non-ESA, which are required when installing lowering fork springs on a standard height bike.
Please note:
5wt oil is recommended for general purpose and for more dirt road riding.
7wt oil is recommended for sport-oriented street riding.
Air chamber is 160mm with springs removed and forks completely compressed.
Instructions for setting air chamber:
1) Remove fork spring and drain old oil.
2) Compress fork fully with spring removed.
3) Add oil until oil level is the prescribed distance from the top of the tube - this is your air chamber.
Piston rods should be pumped several times to dispel any remaining air before final measurement is made.
