I've submitted a rating for Avon 3D Ultrasports before, but in addition to being a great all around sport tire, I must say I was impressed with Avon's road hazard warranty. Shortly after mounting I ran through some debris at a construction site and a shard went into the rear tire. I purchased a replacement and sent the damaged one back through Motorcycle Superstore. They subsequently credited back the full amount of the replacement. No issues with them. Highly recommend them. I'll never buy another brand of tire.
I ride very hard and very fast on my gsxr 600. Ive had this tire a little over a month now and it's already bald in the down the middle. Good traction and does heat up fast. A good tire just to get u by but for anyone looking for a tire to last longer then a couple weeks, spend the extra money and get a better tire.
Installed a set on my 02 BMW1150RS. Best set by far. I've had seveval other popular brands on before none match the grip and feel of these. You should not be able to lean as far as these do on the street they work that well. They seem to warm up quickly, dry traction is superb. Have only ridden on damp and wnt roads, no heavy rain and they work well. Wish i found these a while ago as my bike is now for sale, so i won't get to enjoy them. They will definitely go on my new bike and well before the OEM tires wear out!
I started with a 2008 Road Glide, installed a 120R motor, raked the front end 11 degrees, and shod the 23" front wheel and the 18" rear with the Avon Cobra tire. (120/60/23 fr., 150/70/18rr.) I broke the bike in properly, borrowed my friend's V-Box, and per it, ran a 10:58 second quarter at 125. I geared it a little tall, so it lost traction at the top of first and second. On my normal rides through the Sierra foothills in warm weather, the tire is great, slipping occasionally when over-powered. But in the cold, it is easily over-powered, and scrubs in the corners. (Temperature lower than 60F) I was in second gear at 2500RPMs, and gave it full throttle, and the rear spun for 2-300 feet. It did not get sticky at all. So, be careful when riding in the cold.
