The Harley-Davidson has been making motorcycles since the start of motorcycle era, and keeping an authentic concept.
The bikes are comfortable but heavy and not well suited for extreme riding.
OEM suspensions are too soft, easily bottom out and swing the bike.
We install 14in adjustable rear shocks and pressurized fork cartridges by Legend manufacturer that specializes in Harley-Davidson motorcycles
Watch the test drive of these suspensions by pro rider and motorcycle instructor Alexander Andreev at our channel.
To replace parts, you will need a lift and a set of tools, including an inch ones
To remove the shocks, it is necessary to lift the swingarm with the rear wheel
We recommend to start the installation of the shocks from the right in order to have access to the lower mount,
otherwise, you will have to remove the exhaust system or put the motorcycle on wheels to compress the left shock absorber.
It is convenient to remove the old thread lock with a threading die
The shock is installed with the stop ring outward.
For bottom mount the bushing and washer from the kit are used
For upper mount the bushing and washer from the kit and thin OEM washer are used
The left shock absorber is installed in the same way, but the lower bolt is fixed with a nut
Legend uses a rigid joint instead of silentblock in the OEM shocks.
Installation of cartridges starts with removing the wheel and fork.
The front fender is mounted with an inch Allen bolts The brake calipers are fixed with 12-point bolts
To remove the wheel, unscrew the axle nut and loosen the clamp on the right fork leg
After loosening the upper triple clamp, loosen the fork cap while the fork leg is fixed in the lower triple clamp
Measure the fork leg protrusion to set it when assembling
Now the fork can be removed
Dissasembling of fork legs starts with damper rod bolt
The best way is to use impact wrench to prevent cranking of the damper rod with the bolt
Pump the fork leg to drain maximum quantity of oil
The same procedure with another fork leg
Unscrewing the cap, you should be prepared for a release of the spring
Dyna Fat Bob has two similar fork legs with primitive damper rods with spring inside
Instead of OEM inside parts, we install Legends pressurized cartridges.
This cartridge is an independent sealed two-chamber shock absorber with a valve The damper is already filled with oil under high pressure due to the chamber with compressed nitrogen.
External port allows to easily control nitrogen pressure
Fork oil is included
The two-chamber design provides comfort during normal use and stability during extreme riding
Pressurized nitrogen prevents the oil from boiling during intensive work
The cartridges have spring preload adjustment for the weight load, which consists of the weight of the rider with gear and the weight of the installed equipment
The adjustment table is indicated in the instructions.
In our case, it is necessary (we need) to make two turns of the nut and fix it with a stud in the flat cutout on the rod
Top out springs are used from the Legend kit
Next, the cartridge is installed in a well-cleaned fork leg and fixed with the damper bolt on the thread lock to 40 Nm
Next, fill the fork leg with 370mm milliliters of oil
Before tightening the fork cap, the fork leg needs to be pumped several times to make sure that the oil is in the lower chamber
The fork cap is tightened to 30 НМ.
The supplied spacer is not required, as it is intended for a fork from another Harley model, with a piston-damper in one leg instead of a damper rod.
The second fork leg is assembled in the same way.
Front end assembly is carried out in reverse order.
First, tighten the lower triple clamp to 45NM.
Next - tighten the upper triple clamp with the same torque
Axle nut is tightened to 100NM
To fix The right fork leg on the axle - first tighten the rear bolt to 20Nm, after front bolt with the same torque
Brake caliper bolts are tightened to 45nm
Finally, the preload of rear shocks must be adjusted symmetrically on both sides so that the sag is one inch under full load.
Recommended settings are indicated in the instructions
Rebound damping at point 6 also increases compression resistance.
With the new fork and shocks, FatBob is noticeably higher, allowing to tilt deeper while cornering and confidently pass obstacles
