Available in chrome, black, and polished copper finishes, these Leaf Spring Fork Assemblies will make any custom bike stand out in a parking lot. Also included are the cap and crown nuts. with ears for Dog Bone risers, or without ears for Glide-style risers. Front wheels from 16" to 21" with 3/4"-diameter axles can be easily fitted, and can be set up with single or dual disc brakes. The forks measure 20"-long from the bottom of the stem to the front axle, and fit on most stock length Harley-type frame necks with 1" bearings. The rockers have been upgraded with Paughco’s special high-strength, self lubricating space-tech cast nylon bushings, for long and reliable service. Other fork designs are girder forks, suspended on sprung parallel links. The forward spring support legs are solid 3/4" mild steel bar. Straight reinforced girder: Front/rear suspension (mm) Front: 1480 rear: 3020: Departure angle: Front: 14 Rear: 12: suspension : Leaf spring /9/10: Leaf spring: Front: 9 Rear: 10 Axle : 7 tons of front Dongfeng axle and 10 tons of rear Dongfeng axle: Number of the axle: 3pcs: Wheelbase (mm) 4350+1350: Number of tires: 10pcs With 1 spare. The most common form of front suspension for a modern motorcycle is the telescopic fork. They are relatively easy to replace on your own after you raise the vehicle up with a floor jack. They’re made from special, swaged one-piece 1-1/4" heavy-wall (.187") tubing for the rear leg, along with 3/4" heavy-wall (.120") for the front leg. Leaf springs are an integral part of a vehicle's suspension system. The rub is that fork leg bottom rocker pin holes are always f'd up quite badly and have to be fixed first.Įxcept for only being able to process small bumps, when restored properly, the Indian leaf spring fork is heads and shoulders superior in handling to the girder and telescopic forks as designed.These fork assemblies were brought back to life by Kiwi-Indian motorcycles and are upgraded from the original forks built back in the 20’s and 30’s. I didn't explain it simply but the concept is dead simple. In short, all the pieces, together, need to be a nearly perfect inflexible rectangle, moving freely through all the perfectly parallel bushings and mating pins. Remove the stud and repeat test with front wheel at its "full bump" position and results have to be the same for complete freedom of the linkage to move and not impart any torsion or bending resistance to the action of the leaf spring pack doing its job. I think it's welded in but I'll probably be back at the garage working on it in the next day or two. MMW carries a wide variety of Front Ends. While there are some differences, those general thoughts also apply to other non-hydraulic front ends, like girder and leaf spring front ends (which are largely found in the aftermarket). There are other Indian front ends better suited for a bobber, namely the late-model Chief telescopics, or 741 military forks (which are 2 longer than Sport Scout forks). Looks like Jimmy Durantes nose sticking out the front of the bike. When it comes to Front Ends, Malibu Motorcycle Works does it with style no matter which style you choose from. Both leaf-spring and post-war girder front ends have their devotees, and their detractors. If everything is correct, the stud should easily shoulder up tight to the fork link rods without distorting ANYTHING. I don't even like original Indian leaf spring front ends. The basic fork assembly consists of a solid-mounted girder (called the fork front frame in the parts book), with rockers on either side at the bottom.
Leaf spring girder front end install#
With the wheel at its working rebound "droop" position, try to install and tighten the spring eye stud to both fork link rods. When you tighten the rocker pivot pin it's at a crazy angle to the fork spring eye stud, causing bind when stroked through the spring stroke arc.Įasiest way to determine bind is to tighten everything in the rocker assembly.Ĭomplete front wheel/axle assembly must be installed tight.įork link rods must be installed properly to the rockers. "The most common fault in leaf spring setup is found at the rocker pivot pin to fork leg not being dead-on center aligned with each other and/or the holes on lower fork legs are wallowed out or one or both "pads" surrounding the holes are very worn from the rocker pins left loose for years.
