I have done a bunch of research on these tires and have recieved feedback for them on everything from R6, 600 GSXR, and Ninja's to ZX10's, ZX14's, R1's and Busa's and I have not found or recieved a bad report on them yet. Here is a couple of reviews from Motorsport.com
"I have used the Continental Motion Tires for a year now. They are high mileage usage tires and when you need them for performance they produce better than indicated. 7500 miles and more on the rear tire of my ZX14 is outstanding. The grip in corners and when I am doing canyon riding is even better. I have used Pilots and Qualifiers but these tires give the same performance."
"I purchased the Continental Motion tire combo for my 2006 ZX-10R. I have been riding for over 25 years and have always rode on Dunlops. I did my research on the tires and also read countless reviews before actually placing my order. I wish I wouldn't have waited so long! The tires have amazing grip ( first ride with them it was 41 degrees). Even at the cold temperature, the felt like slicks at 90 degrees. They absorbed the rode imperfections gracefully with very little transfer to the grips. The reviews were a big factor in buying them, so I hope this helps someone else make a change that they won't regret. I am impressed and pleased with them thoroughly."
These are just a couple of the posititve reviews I have found on these tires. Like I said I have not found a bad review on them yet. I also talked the local motorcycle dealerships in my area of the state (SE, Wisconsin - West Bend, Cedarburg, Grafton areas) and they all say the Conti Motion's are excellent tires and hard to beat for the money.
I will be putting a set on my 07 FZ1 this spring and will give a review of these tires on this thread.
