Can I get some tired advice?

It could also be the way the Avons on it are worn. If worn kind of flat instead of even it'll surely make it feel awkward and non linear. I'd suggest stick with Avons front and rear solely for one reason, Avons are cheaper and very very soft so grip well, while learning the bike there is no such thing as too much grip
 


Like Clav said, go with bridgy Excedra Max on rear. It's a 55 instead of 50 so the slightly tall rear combined with shorter front makes for a great rake angle to improve your handling immensely
 
Thanks Clav and Tex! I like sticky and would choose that over other characteristics. I had a Shinko rear on the Max that had a death grip on the pavement. It was a one season tire but worth the trouble of replacing more often. I think the Avon will last even longer. Thanks for your input on this subject.
 
I've had great performance out of the Bridstone Extrada, only in the front as I'm a darksider for the rear
 
I run a excedra max 170 rear tire up front and a Yokohama Envigor 205/60r16 on the rear of my r3t and I love the set up.
 
When I had the Avons on the Rocket I only got about 8,000 on the rear and the front tire did not wear correctly, not cupped but uneven wear. (flat)
