BMW ad­mit fork fail­ures

BMW have is­sued a ma­jor re­call for all R1200GS and R1200GS Ad­ven­ture mod­els man­u­fac­tured be­tween Novem­ber 2013 and June 2017. BMW say that the fork stan­chion can suf­fer dam­age if sub­jected to “mo­men­tary high stress”, which can re­sult in the fork tube com­ing loose. In worst case sce­nar­ios this can re­sult in the fork be­com­ing com­pletely sep­a­rated from the yoke, re­sult­ing in an im­me­di­ate front-end fail­ure.

It’s im­por­tant to note that there are no known in­stances of this hap­pen­ing as a re­sult of nor­mal road use, but bikes which have been used ex­ten­sively off-road, or which have ex­pe­ri­enced high-im­pact shocks to the front fork, could have sus­tained dam­age.

All bikes cov­ered by the re­call pe­riod will be retro-fit­ted with an ad­di­tional fixed fork tube bush which slides over the ex­ist­ing fork tube to strengthen it – un­less there is ev­i­dence that the fork has al­ready sus­tained dam­age. If that is the case, the fixed fork tubes will be re­placed by mod­i­fied new parts.

BMW Mo­tor­rad say that “dur­ing on­go­ing field ob­ser­va­tions, the fixed fork tube of the spec­i­fied mod­els can suf­fer dam­age, due to un­usual in­ci­dents with mo­men­tary high stress, without the user notic­ing. Po­ten­tial pre­lim­i­nary dam­age to the fixed fork tube man­i­fests it­self through a gap be­tween the pipe and the pressed-in, top seal plugs.

“If the fit of the pressed-in seal plug has loos­ened, the gap may in­crease through longer, high-stress us­age. This may lead to oil leaks and noise. If these sig­nals are not per­ceived, or are ig­nored, and fur­ther high-stress in­ci­dents oc­cur, the plug may become com­pletely loose. Sub­se­quently, crit­i­cal driv­ing con­di­tions can­not be ruled out.” That crit­i­cal con­di­tion could be a fork de­tach­ment.

Own­ers of af­fected mod­els will be in­formed by BMW, and all re­me­dial work will be car­ried out for free by a lo­cal BMW Mo­tor­rad ser­vice cen­tre.

BMW have fur­ther con­firmed to MCN that: “All bikes built from June 2017 will have a mod­i­fied de­sign of fork fit­ted on the pro­duc­tion line. There have been no in­ci­dents of any cus­tomer bikes suf­fer­ing fork stan­chion fail­ures that have been re­ported to BMW Mo­tor­rad UK.”

How­ever, bikes used at the firm’s sup­ported off-road school have suf­fered is­sues, as BMW Mo­tor­rad UK con­cede: “The BMW Off Road Skills cen­tre in Wales has ex­pe­ri­enced fork stan­chion move­ment on some of their fleet of R1200GS mo­tor­cy­cles and, since the sit­u­a­tion first be­came known, all of the school’s bikes have been checked nightly. There have been no fork sep­a­ra­tion is­sues at the BMW Off Road Skills fa­cil­ity in Wales.”

MCN’S own in­ves­ti­ga­tions sup­port BMW’S claims, but have un­cov­ered re­ported fail­ures in other coun­tries, and sug­gest that pro­longed, or ag­gres­sive off-road use can cause the is­sue.

This is the sort of rid­ing that BMW say could in­sti­gate prob­lems with the GS fork
