Initial Impression is "confidence inspiring" - These tires are wonderful and make the bike feel sportier than it is. The bike is much quicker to turn in and the lean angle is greater than what I could confidently achieve with the Metzeler's (even when new). The old tires had a tendency to kick out in the rear under hard corning. Not so with the Avon's. They turn in quickly and hold the line. There is reduced tracking across grated bridge surfaces or squirming on road-snakes as well. The ride comfort is equal to the Metzeler's but that was never my complaint. The Avon's are far more compliant across all riding scenarios. I no longer have to think about tire performance related to riding style or the architecture of the road. The Avon's (even while brand new) have superior grip.
The tread pattern on the Metzler's favored tracking and squirming and the rear seemed to be quite square compared to the Avon rear tire profile. The Avon's are more of what we understand to be a typical mid-range sport tire but seem to suit the R60/2 rather nicely. As others have pointed out, they do not look "period correct". Not a concern of mine.
If you want to sacrifice handling for looks then these are not your tires. However if you're all about ride-ability and corning, the Avon's seem to be quite good. I feel as though I have a new bike.

I talked to Vech about this and he said since we're not talking much horsepower here, and if the 90/90 front tire was mounted backwards, there shouldn't be a problem.
Comments are welcome from members who have experience with these tires on their singles and know which combination works and which doesn't. Thanks, Joe
