Getting ready to do my first change of both the Gearbox oil and Final Drive oil on my recently acquired K1200lt. I bought it in May and have put 10000 trouble free miles on it. I figured this winter would be a good opportunity to change all of the fluids, including brake fluid. I have been looking at Red Line's Heavy shock proof gear oil, and was wondering if anyone had experience with this stuff. Is it safe for both the Gearbox and the final drive?
