#HARLEY GIRDER FRONT END SHOCK FREE#

Hey all, I'm really new to this whole custom bike building thing. I think they did 2 catalogs a year and inventory changed over time but you can no longer buy direct from them if they even exist at all anymore. But heres from the 1984 Edition of the Jammer catalog. ** I found the disc with the other pictures on it, I have other catalogs but TNC is your best bet on that one. (The oil inside overheats) However modern shocks are much better designs and quality so consider that before using any old crusty swap meet find. My experience with vintage shocks on front ends were that ridden hard, the shocks got overwhelmed and didnt perform well. The dealer then fitted the springs to the application IE: 250cc Triumph vs 500 vs 650 or 750 Triumph but most ran the same shock. For example on vintage British bikes most were fitted with one specific brand and the specs were the length and shrouded or unshrouded.

Shock absorbers themselves are just a shock and designed for certain applications but dont care if its on the back of a Bagger, Minibike, or a Girder, they have holes and fluid inside, the spring and free length as well as travel are specced to match the application. TNC seems good at ID'ing period front ends, on the springer 'How do they ride' post I inserted some period photos of the Jammer catalog as I have several old copies, but they ran a shock on Girders and IMHO was one of the best setups.Д«ut not all girders run a shock, some just a spring (Bouncy Bouncy) and springers & Girders with only springs tend to pogo. down to 5/8 inch, and a lightweight fork tapering from about 3/4 inch down to 1/2 inch.Post good pix and measurements of the part thats missing.

Norton, for example, built a heavyweight fork from tubes that tapered from about 7/8 inch O.D. Many manufacturers produced forks using different size tubing for different applications. And before fitting a set of used girder forks, make sure theyвЂ™re up to the job. The slender tubes used on Webb/Brampton forks are especially prone to rusting from the inside. Regularly inspect fork legs for cracks and signs of rust. Spindles are made of special steels, and only replacements designed for fork applications should be used. Bushings wear over time and may need to be replaced, especially if maintenance has been neglected. Whatever the style, all girder forks have pivot points and/or sliders that need to be kept well greased. He traded it for a 250cc BSA - but not before the Triumph had twice pitched him off! My father rode a 500cc Triumph so equipped in the early 1930s and declared it to be an evil handling bike. Though not fitting into either category, Triumph fitted some of their 1920s motorcycles with a girder fork that paired a hinged lower link and a slider at the top, meaning the fork would move backward and forward during compression, altering the steering geometry. The вЂњmodernвЂќ Harley Springer front end is essentially a development of the first leading-link design but with progressive compression and rebound springs. The British Castle fork fitted to the Brough Superior closely followed the Harley design, but added large rotary friction dampers. The leading-link fork fitted to Harley-Davidsons carried the front wheel axle ahead of the spring leg, which slid against a coil spring carried in the main fork. VincentвЂ™s own Girdraulic fork used forged alloy blades for extra strength instead of the welded tube construction of the Brampton, and added hydraulic damping.

The Brampton fork, later fitted to Vincents, was similar in concept to the Webb. Webb ever made any money from his invention is unlikely, as just about every British motorcycle manufacturer built its own fork following the basic Webb design. Advantages over the Druid included the option of a rotary friction damper and tapered coil springs for progressive compression. Most popular in terms of usage on pre-WWII British motorcycles was the Webb fork, which again used a parallelogram linkage to allow for suspension travel, usually controlled by a large central spring.
