I need some advice. I own a 15 Cross Country Tour. I have 5700 miles on it with Metzler 888 front and rear. I run my tires +3 recommend psi. The air shock at 32 psi. Also i installed a Klockwerxs windscreen. At 70 mph the bike is fine. Getting over 100 the front and rear feel unstable. I dont how to describe it but as wicked loose. This has been happening since I purchased the bike new. Hopefully someone can give me some advice.
