Just thought I'd throw this out there. I need new tires for my 77 750 supersport. I have a metzeler tire on the back, and a chin shin, with ribs vertical on the front. This is how it was when I recently bought the bike. I noticed on less than smooth roads, and when crossing painted lines on the road I have a little shaking. Kind of scary. I previously had a 75 CB 360T that I had put Avon Roadrider AM26 tires on, and it made a huge difference. I read on this site that Honda Man advises to use ribbed tires because of head shake on deceleration. So, what are you guys running, what's the preference.
