As long as there is nothing wrong with your front end like the bearings and tire pressure, it might have just felt hard. First time in hard turns at this speed? If you was nervous it could have just seemed like a problem.
My first hard turn I was not expecting, and although I was going 5 MH below seed limit into the curve, I felt like I had to keep the bike with me, and held my breath LOL. The next time I was ready for it and still felt funny but not like before. I hit it two more times that day for practice and now it seems like any other curve.
Do your PM checks likes nut/bolts, tire pressure, etc... to elimanate any possible problems.
