You have to wait so long because a lt of the parts have not be yet made for the R1200GS!
Mind you BMW still to date have not made the mounting plates for the excellent Alu 'Explorer' cases made for the 1150 ...
How long has the R1200GS been out?.......
Call Touratech Germany as the bits come from there! if you can get any sense from them...great engineers, great kit but on communications....null points!!
I take it all back! after a visit to Touratech In Germany, I met a chap there called Barry who speaks excellent English and was most helpful- He drove me to get a pizza for lunch whilst the mechanics got busy!
Well woth the visit... but if you can't resist temptation...... ,
