480miles on my 2nd brute and the rear output seal is already leaking oil. I had to replace several of them on my 650i. Brutes are solid and reliable but these seals are a weak point, very frustrating to keep dealing with, even if they are cheap. I've heard through a shop it was a general problem that kawie uses crappy seals, anyone else?

 

Anyone else???
Answer is yes.

What you need to do to stop keep replacing is to update your seal to 2012 spec, and be done with it permanently.
