Repairs and Information


Important Information: On 11/13/98 BMW NA issued service bulletin #2851 regarding "Tampering/Non BMW Approved Modifications". This service bulletin states that a warrantee claim for repairs on your motorcycle could be denied if a "causal" relationship can be shown between a modification or use of non-approved parts and the mechanical failure.  For more information please contact your dealer. And please take the time to read Rob Lentini's thoughts on this issue. Following soon after Service Bulletin #2851, BMW NA issued Service Bulletin #2852 with even tighter restrictions that could void your warranty.
