These billet Tolle triple trees are available in 3° and 7° raked versions. To ensure a comfortable ride and easy handling of your motorcycle make sure you choose the correct rake and fork tube length combination for the correct trail, if in doubt check with your Zodiac dealer. Correct trail is 5 cm to 10 cm (2" to 4") for rigid frames and 8 cm to 15 cm (3 1/4" to 6") for swing arm frames. The upper tree of the Fat Bob Custom Style trees has open slots, which increases the pressure on the tubes instead of the tube cups. This significantly increases the stability, particularly with long forks. The lower trees have open slots in the rear, to properly secure the tubes. OEM or other triple trees do not have this feature. The triple trees have a width of 250mm and will accept 1 5/8" (41.27mm) fork tubes, but will also take 35mm and 39mm fork tubes when proper adaptor bushings and top fork tube plugs are used. Steering stops, adaptor bushings, as well as other triple tree related parts are available separately. Note: Tolle does not recommend use of these Triple Trees for forks longer than 12" over stock FL (40" or 1015mm measured from the underside of the upper tree to the center of the wheel axle) and a trail not exceeding 5 1/8" (130mm).
