Bought a 2011 RT in March. I just turned 10,500 miles on Saturday after a 1000 mile interstate cruise. Sunday found a puddle of oil under the bike. Looks like its coming from the rear of the motor. Took it to the dealer for an in warranty repair. The mechanic at Bob's BMW here in MD tells me it looks like the rear main seal or the balancing shaft seal. Won't be certain of the source 'til the trans is removed. I noticed a vibration on Saturday during my ride but frankly thought it was the speed/RPM's I was running. I typically don't cruise at 75-8o mph. But it was WV highway with 70mph speed limits mostly. ANYONE EVER HEAR OF THIS OIL LEAK ON A LATE MODEL RT? I am concerned it's a symptom of a greater problem.
