I won't ride anything else! Been riding them for many years, tried others in between, always go back to them, smiling!
How many miles do you typically get out of a set?
The last ones went well past 30k miles before I had cancer and parked them for almost 5 years. They got a little dry-cracked from the long sit, and when I got better we got new feet under both of us (me and my trusty 750!). I started then in 2005 with their "vintage" version Roadrunners, ribbed front and zigzag pattern rear, but it was a little too square for my riding style, and I was mighty hard on the narrow 'corner' of the rear one in 8k miles, so I upgraded to the AM26 series Roadriders in inch size in 2006. Absolutely loved them. They still look brand new, but I just bought a set of the metric version for next year, to experiment with some chassis geometry stuff (different profiles). These I have now are going onto the next resto 750K2 I am working on for next year, still have about 20k-30k miles in them, I would estimate.
Wait are you telling me you have 20k-30k on the am26 Avon roadriders? How the hell is that possible?
I don't have that many on this set: the Roadrunners I used from 1996 to 2001 had about 34k on them when I got 'parked' for a while. When I came back for another set, the same tread pattern was gone in the Roadrunners, but I tried the new ones in 4.00x18 rear and 3.25x19 front. The front ribbed one is great, but the rear one is designed for Brit twins and has a limited lean angle, which I overcame daily. I wore out the corners of the rear on short order, while the center was fine. So I switched up to the AM26 series in 2005, size 4.00x18 rear and 3.25x19 front. The new ones I am going to install next season are the 100/90x19 front and 120/90x18 rear, with shorter rear shocks and new air fork fitting up front. Switching things up for a 3.50" front trail this time around...
I'm looking at the 100/90-19 for the front. For the back I've heard going with the 120's they'll square off in a short while, thoughts on that?
I haven't experienced that at all with the Avons. Be sure, though, to run them at higher air pressure: the labels on the bike were for the old bias-ply wrapped Bridgestones. I use 35-38 PSI front (Windjammer fairing attached) and 38-44 PSI rear.
If you haven't read it in my book: the magic number for YOUR OWN tire pressures can be arrived at over a short testing period. First, you record your air pressures, then go for a ride of at least 10 miles (20 is better) and measure them again, to see how much they increased when the tire warmed up. If it is more than 2 PSI, then add 2 PSI to the beginning number and repeat the test the next day, from a cold start. If it is LESS than 2 PSI increase, then drop it 2 PSI and test again, from cold. The 2 PSI number was created by Continental tire engineers on 850cc Beemers in the late 1970s when the now-famous Continental Twins were being developed (now gone, sadly), but the method is perfect for these bikes.
