Breather plug Make sure to aerate the front fork at regular intervals: Put the motorcycle on a workstand so that the front wheel barely touches the ground. Loosen the breather plug to release excessive pressure in the front fork. Recommended Service Intervals Every 25 hours. Make your service and maintenance according to Öhlins Workshop manual. Disposal Discarded Öhlins products should be handed over to an authorized Öhlins workshop or distributor for proper disposa Compression damping adjuster The compression adjuster is located at the top of the fork leg. Adjust by turning the slotted screw with a screwdriver. Rebound damping adjuster The rebound adjuster is located at the bottom of the fork leg. Adjust by turning the slotted screw with a screwdriver. To Reset The adjusters have a normal right hand thread. Turn the damping adjusters gently clockwise to fully closed (pos. zero [0]). To open, turn counter clockwise, and count the clicks until you reach the recommended number. For recommended clicks see Set-up data. Static sag can only be changed with softer or harder spring rate.

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. Front shock installation. Note that the shock body is at the top with the shaft pointing down. ARS shown is in the unloaded position. Fig. 2. Rear shock mounting with ARS. Position the lever so that it will not come in contact with any vehicle parts around it. The cup can be rotated to reposition the lever if necessary.
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

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

1. Raise the motorcycle and support it to enable the rear suspension to hang free. 2. Remove the stock rear link & struts. 3. Remove the link bearings and sleeves from the stock link with the exception of the bearings and sleeve in the middle of the link. You will be using the bearing & sleeve listed above in the middle position of the new link. This is the same bearing and sleeve that is used at the front of the Link. 4. Press the bearings into the new link making sure that the bearings are centered in the link. 5. Lubricate the bearings with high-pressure synthetic grease. 6. Install the sleeves in the same position as removed using the one listed above in the middle position. 7. Reinstall the link using the new bolt supplied in the kit in the middle position. 8. Torque all the bolts to the factory specifications. Torque the special bolt supplied in the kit to 70Nm, 50Ft-Lb. Blue Locktite is recommended. 9. As a rule of thumb the spring rate should be increased 0.5 kg or 28 lbs. in relation to the spring rate that is currently being used. This is a good starting point. Note: This kit is designed for single rider racing applications. The spring rate and dampening must be tailored for the individual rider weight, style of riding, motorcycle weight and track conditions. An experienced race mechanic using only the appropriate tools for removal and replacement of bearings and other components should only install this kit.

The K 1300 S with 175 hp, the K 1300 R with 173 hp and the K 1300 GT with 160 hp. The new K bikes feature updated transmission and clutch assembly, plus smoother engine performance and new switchgear. Von Kuenheim continues: “By raising capacity to 1300 cc, our engineers have not only increased output but also torque on all three models. At the same time the driveline was intensively revised from air/fuel mixture formation right through to the exhaust system. In this way we have been able to optimize partial load behavior as well as throttle response. Now the clutch can be operated with even less effort and with greater refinement. Shifting has been improved tangibly due to constructional changes to the gearbox and drive.” BMW is introducing new options for the 2009 as well. The popular Electronic Suspension Adjustment that first appeared on the 2005 K 1200 S has now been updated with even more on-the-fly adjustability and it’s called ESA II. Also new is the quick-shifter option, racing-style gear shift assistant, borrowed from BMW’s race-ready HP2 Sport. Automatic Stability Control (ASC) is also offered as an option on the new K bikes. “Both the K 1300 S and also the R will also have the shift assistant – familiar from the HP2 Sport – available as an option for the first time,” von Kuenheim emphasized. “We have also advanced the chassis. The new lower longitudinal strut is now made of aluminum and is thus considerably lighter. This makes the front wheel guidance response even more sensitive. The result of this comprehensive development work is superior handling, improved rideability and lower fuel consumption. The electronically adjustable suspension – called ESA in short – was launched as a world first on the K 1200 S. Now we are presenting the new, well-proven ESA II as an option for the K Series. Apart from the suspension and damping this unique system also allows the spring rate to be adjusted at the press of a button. The K Series model revision also heralds a new and innovative generation of switches and controls.
