I have 72,000 miles on my bike now, and the front and rear shocks are OEM. Bike doesn't feel as secure on the road now as when it was newer and I'm thinking about replacing them. I ride 2-up frequently, mostly highway, loaded bags.
Any suggestions for a cost-effective upgrade? Do I have to replace both front and rear? I'm planning on keeping the bike for another 50,000 miles or so.
