Wilbers Zero Friction Progressive Fork Springs / Tenere 700
The stock fork springs are 6.0 kg/mm which is about 5.8 N/mm. These Wilbers fork springs have a starting rate of 6.0 N/mm for comfort and traction over the smaller bumps, but then ramp up 25% to a max rate of 7.5 N/mm for riding street and off road where excessive nosedive, bottoming and blowing through the stroke too quickly is a concern. For a more aggressive ramp up see our Yacugar fork springs on this page.
Please note:
5wt oil is recommended for general purpose and for more dirt road riding.
10wt oil is recommended for sport-oriented street riding.
Air chamber is 120mm 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.
