some old G103 maintenance manual on the webhttp://tinyurl.com/G103MM
doesn't mention anything about changing brake fluid every two years as is
common in most cars, however the DG505 needs it done every 4 years.http://tinyurl.com/5zy2wj

I wouldn't let it go that long myself. I change the brake fluids (all
fluids really) in my bike every year. It's the water accumulated in
the automotive brake fluid that causes the corrosion that kills the
cylinders.
