MULTI-RATE SPRINGS AND THE ARS SYSTEM Depending on the application dual–rate springs are fitted on the shocks. Dual-rate springs are just that– a spring set with two separate rates. This is done with a short spring stacked on a longer spring. As both springs collapse they produce a soft, or initial, rate. The spring set will maintain this initial rate until the short spring stops compressing. At that point, the spring rate “crosses over” to the stiffer, or final, rate. This multi-rate system allows a soft initial rate for comfort on small bumps, but has the capability of soaking up the big pot-holes and other off road hazards. ARS stands for Adjustable Rate Suspension. ARS is available on some dual-rate spring 4-wheel ATV shocks. ARS differs from spring preload. The ARS system allows the rider to increase or decrease the load-carrying capacity of the shocks by turning a lever. Depending on the application and spring set, the rider can increase the load capacity of the shocks up to 50 percent. The average preloader that makes a half-inch increase in preload will HONDA 450E/S MOUNTING & ARS ADJUSTMENT INSTRUCTIONS Continued on next page. #TRX450 – 5/28/99 #TRX450 – 5/28/99 Fig. 1.

increase the capacity of the shocks to only about 5 to 10 percent. ARS allows the shocks to be correct for solo riding, but still handle the increased weight of an added load. ARS can also be employed to stiffen the rates for aggressive riding. The ARS system consists of an indexing lever and a stepped cup that contains the short spring of the dual- rate. The position of the lever in relation to the steps in the cup determines how long the spring set remains on the soft, or initial, spring rate. On most ARS applications, four positions can be selected from full stiff to full soft. Indexing is done in a matter of seconds by rotating the lever or the cup by hand. Indexing the cup to the lever is usually preferable to avoid interference. Adjustment of the ARS system should only be made while the vehicle is unloaded to reduce the load on the springs. NOTE: It is important to make sure that a step in the cup is positioned directly over the tang on the lever. This will prevent damage to the cup and/or lever that can be caused by making partial contact between the tang and a step. In addition, make sure that the lever will not contact any vehicle parts around it, as the suspension moves up. TUNING TIPS—The “softest” setting on the ARS does not mean that the ride will be the most comfortable at that setting. It means that this is the softest spring setting which would be employed on smooth trails or without a load. Excessive suspension bottoming caused by rough conditions or by the addition of a large load will cause a harsh ride when the shock is adjusted to this setting. To eliminate this bottoming, adjust the ARS to the stiffer positions for a more comfortable ride. Hence, sometimes “stiffer is softer.” NITROGEN PRESSURES IN EMULSION SHOCKS

1. Remove fork springs according to instructions contained in your shop manual. For maximum performance we highly recommend that the forks be thoroughly cleaned, inspected and new fork oil installed. Note: If your motorcycle comes equipped with two fork springs in each leg (long & short), remove and discard both springs and the flat washer between the springs. If a stock spacer exits, remove it. If there is a short spring on the damper rod, do not remove it! 2. Use the recommended fork oil viscosity as noted in your owners manual with the following exceptions: GL1100 20 weight, GL1200/1500 15 weight required. See fine tuning for more in- formation. Fork oil level/volume should be checked according to the steps outlined in your authorized shop manual. Measurement of your fork oil by level is the preferred method. However, some manuals only specify a volume measurement. Due to the design of a progressive wound fork spring it will displace more oil thus requiring a maximum oil level of 5.5″ (140mm). Caution: This is not a recommendation, it is only a precautionary statement. If your manual specifies an oil level higher than 5.5″ (140mm) set the oil level at 5.5″ (140mm). (Oil level is the distance from the top of the fork tube to the top of the oil with the fork completely collapsed and the fork spring removed see figure 1.) This measurement can be made by using either one of the Progressive Suspension Fork Oil Level Adjusters (FOL-1 or FOL-2). 3. Install your new fork springs into the forks. Mechanically, it makes no difference which way the springs are installed. Some manuals will state; install the spring with the close wound end towards the bottom. This is done because sometimes there will be less spring noise. The springs will perform exactly the same regardless of which direction they are placed. Check the spacer length requirement for your motorcycle in the enclosed supplement. If not listed, you must calculate the pre-load. What is pre-load? Pre-load is the distance the spring compresses when the fork cap is installed. You may or may not utilize a spacer to achieve proper pre-load. The spacer in itself is not “pre-load”. It just helps to achieve it. Why is pre-load important? It determines the proper ride height which in turn affects how the bike handles.

SHOCK REMOVAL AND INSTALLATION– The shocks are fitted with special length spacers to maintain correct alignment between the frame and the swingarm. If the shocks are removed for service or repair, they must be installed in the correct position. Refer to the diagram on the next page for spacer positioning and layout. NOTE: Misalignment between the mounts on the frame and the mounts on the swingarm can cause binding between the shock shaft and shaft bushing. Misalignment of more than 1/4 inch can cause the shocks to bind up and not function properly. If this binding occurs, the shocks will feel overly stiff and harsh. Follow the procedures below to check for misalignment when installing the shocks. NOTE: The shock bushings are designed to have a certain side-to-side “float” to keep them from binding. As a result, do not grind or file the inner or outer edges of the bushings to make them narrower. The amount of “float” in the bushing set is necessary to ensure smooth operation of the damper assembly. If the shock eyes are tightened metal-to-metal (the outer faces of the eyes to the flanges or washers), this will lead to a harsh, stiff or choppy ride and premature seal leakage or damage to the shafts. MULTI-RATE SPRINGS Depending on each application, single or dual-rate springs are available. Dual-rate springs are just that– a spring set with two separate rates. This is done with a short spring stacked on a longer spring. As both springs compress they produce a soft, or initial, rate. The spring set will maintain this initial rate until the short spring stops compressing. At that point, the spring rate “crosses over” to the stiffer, or final, rate. This multi-rate system allows a soft initial rate for comfort on small bumps, but has the capability of soaking up the big pot-holes and other road hazards. PRELOAD ADJUSTMENT— On Works shocks, threaded preload is standard. (See Fig. 2.) This allows the adjustment of the ride height of the motorcycle. The preload is changed by turning a threaded nut down towards the spring (higher ride height) or up away from the spring (lower ride height). The nut is a right-hand thread. It is used primarily to set the ride height for solo riding, but can also be used when
