Complaint: On R 1100 RS models (above serial numbers only) with luggage racks, a crack may develop in the rear section of the frame (see drawing) if a load exceeding the permitted 11 lb. is applied to the luggage rack, or if a top case is used. Remedy: Please check all R 1100 RS models (in serial number range above) which pass through your workshops for cracks on the rear section of the frame. Cracked frames should be exchanged with the new part listed below. The new rear frame has been reinforced to use with larger loads. New Part: 46 51 2 320 698 (reinforced rear frame) Caution: Since the introduction of the rear luggage grid to accommodate the 33 liter removable top box, it is vital that this luggage grid and 33 liter top box not be installed on any of the above unless the reinforced rear frame is fitted, or a frame reinforcement kit is installed (a kit will be made available in the future to reinforce the rear frame of the above models, in order to install the 33 liter top box). The new reinforced rear frame (46 51 2 320 698) has been fitted since May 1995 production. Use of the new rear section of frame on an earlier production bike requires a new rear section of the dual seat as follows: Parts 52 53 2 325 121 Flash Green 52 53 2 325 122 Red Needed: 52 53 2 325 123 Black 52 53 2 325 120 Light Gray 52 53 2 325 211 Anthracite Warranty: Please explain to your customers that the top case can only be installed on bikes with reinforced rear frames. Claims for frame cracks which result from operation with large loads beyond specification will not be honored under the terms of the Limited Motorcycle Warranty.

Install an oil relief valve PN 11 51 1 342 248 into the oil system (item #11 below). This valve was installed in production since black engine number 41956271, and silver engine number 41959303. This valve allows the oil in the cooling circuit to return to the crankcase when the engine is shut off. This will make it easier to determine the ngine oil level, and reduce the possibility of engine oil over-fill. Install new FR 6 DDC spark plugs, part number 12 12 1 342 125. Follow the procedures in the riders manual during start-up and running-in. Do not start the engine until you are ready to go for the road test. Don’t warm up the engine by letting it idle. Please advise the customer to review the starting, and running-in procedures in the Rider’s Manual. Please advise the customer of the 10w30 or 10w40 mineral based oil for the running-in. Also advise him/her not to top up the oil until it reached the minimum oil level as shown in the Rider’s Manual. Topping off prior to the minimum mark can create the illusion of additional oil consumption. This will be covered under the terms of the BMW Motorcycle Limited Warranty (one time only). Authorization is Required. File a warranty claim. Use the following:
