Avon - Speedmaster front
Avon - Safety Mileage rear.

The SM has rather a square profile and lasts for ages and believe me, it sticks on a corner just as well as a rounded profile tyre, even when ridden hard.  I thing it must deform as the bike leans.  Anyway, looking at it static one might think cornering is on a knife edge but in reality it is not.

Uf, looking at SM profile, I cannot believe it perform as good as rounded tyre. Would be afraid to ride hard on it

"Uf, looking at SM profile, I cannot believe it perform as good as rounded tyre. Would be afraid to ride hard on it" they give that impression from a cursory look don't they.

Anecdotally,  I know someone who lapped the isle of man TT circuit on a pair of those at an average speed of 90mph, they where "sticky" tires as concession to production (road bike with lights stripped off and no fairing) racing,  and all in 1952  ;D which at that time got fairly close to pure grand prix racers.

There's certainly more to them than first appearance, as florence's post.

Most of my personal SOHC bikes have them fitted and i surprised the hell out of a guy on a GSXR 1000 when  i passed  him on a 90 degree bend on the outside  ;D

Thanks for all the imput - food for thought. I have Conti's on the 750 K2 and Avon Roadrunners on the CR Rep.  Interesting that everyone is happy with a differing range of tyres! I think all the modern stuff must improve the older bikes - seems the 500 is quite good whatever tyres are fitted maybe.

Well the SM was a revelation for me, I didn't believe it but took one on recommendation of my tyre place, the owner rides bikes.  They are brilliant and I never now have that annoying only worn out in the middle thing.  I'm on my third one now and I just hope they keep making them.

If i was as penniless now as i was then probably, at least they were made in UK and had proper testing/inspection at factory

Back in the day when my 550F2 was my sole form of transport, I first tried TT100's (very 'tippy' into corners and the rear centre wore out quickly) and then a couple of sets of Avon Road Runners and they were always very good with a nice round profile.  The latest set were now dead on age, not wear, and I didn't want to run on old, hard and cracked tyres after putting the bike back on the road after a long layoff. My rims are standard sizes for the 550F2 (1.85 x 19 and 1.85 x18, as stamped into the chrome) and the Avon Road Runner tyres were Front: AM20, 100/90 H19 and Rear: AM21 110/90 H18.
So I began my research last month into the availability of suitably sized and specified tyres. I checked out the Avon Road Riders and although they had appropriate tyres, availability was a problem as I am told the Avon factory had largely shut down during the lockdown and had only recently restarted production. Then a chance conversation with my local dealer brought the Bridgestone Battlax BT46 to my attention. Billed as the modern tyre for the older motorcycle it was available on a 3 day order. So now I have 100/90-19 BT46F on the front and 110/90-18 BT46R on the back. Each one is specifically marked as either a Front or a Rear tyre.  First impressions, before rain stopped play and confined me to barracks, is that they are a good, rounded profile, sticky tyre that I am confident to push in the twisties. Time will tell on the rate of wear.

When I'll need to buy new set, I'll search for "inch" size (e.g. 3.25x19)rather than mm (e.g.100/90 r19 etc) size as first priority. On my K7 750 I have Bridgestones Battlax standard size but they are lower profile than inch size would be,as consequence gearing is affected and speedometer shows higher speed.. On CB550K1 I opted mentioned Avon's AM26 in inch size and they are simply perfect
