Avon Roadrunners?

[xwhatsit]

Anybody know where a stash of them is hidden away? The 18" 100/90 on the rear must have been designed for the 250RS. Narrower than OEM specced, but a BT45 has nothing on it in terms of peg-scraping stability (although works well on the front) and all-round feels-good-man©.

Roadrunner. Great tyre or greatest tyre?

Surely somebody's got some stacked up in the basement of his shop. Nobody buys 18" tyres these days anyway.

I think they're still listed. Try the Avon agents. Very good tyre, I always trusted Avons.

Loved them on my ZXR250. Good for the edges of the tyre no problems. No idea who still stocks them tho.

While my current Avons (Storms) are great (in fact, the best tyres I've ever had on any bike), I've had some that weren't so good.
Had an Avon on the back of my VF500 that was so hard I could spin it up in the dry going around corners. It was still on the bike when I sold it after nearly 5 year's use.
The first set of Avons I had on my VFR750 weren't the best either - didn't wear that well.

oddly the cruisers appear to be getting into this size of late. lots of the show bikes have big 18's and the latest HD Sporty sport thing is wearing 18's

care to cram a 180 onto the rear

Is that right? I'll check it out. The normal tyre places I talked to said they've been discontinued and they make the Roadrider instead now, which looks like a very different tyre with a different profile -- and it's exceedingly expensive, so I can't try it anyway.

I see on Avon UK's site they have a Roadrunner Universal, which is a `classic' tyre with one of those old-fashioned wavy-bar patterns. Probably overpriced as well just because of the aesthetics. Plus, it looks like they only have it in a couple of weird sizes.

The first Roadrunner,which is what they now list as the Roadrunner Universal was a bloody good tyre....I never really liked the newer version.The old Roadrunner was comparable,or maybe even slightly better than the Dunlop TT100.

I've got some good 19in tyres getting good and hard in my storage rack - a Pirelli MT53,a Roadrunner,and a Kenda speedway tyre.I would of been happy if the R65 came with a 19in front.What you need are Dunlop K70's - I am really impressed,and they have yet to hint that they aren't up to what I'm dishing out.

[xwhatsit]

Well if I could get either the Universal or the K70 in a 100/90 18" for reasonable money I'd be tempted to try it. It's not like I need the latest sticky rubber and dual-compounds to get my knee down and make the tyre last more than 3,000kms; the bike is light and sharp and clings to the road like anything, even ancient Chinese vinyl. Tyre wear is minimal. It's more about the profile and `feel' of the tyre.

Looks like the K70s only come in 19" front and 18" rear. 18" rear is 4.00, which is too tall and a touch wide as well.

4.00 x 18 is standard fitment to the might RS

I think 4.10 -- I remember you saying 4.00 is a tall-profile 4.10, the 4.00 BT45 that's on at the moment feels wrong. 4.10 is what's written on the rearsets.

[Motu]

The K70's will feel just right - but you will need to change your bars.Dunlop TT100's come in 4.10....and you can get race compound too.

[xwhatsit]

4.10 is a little bigger than 100/90 though, isn't it?

Bwahaha. I'm not doing a CB250RS street tracker, I haven't finished the café racer version yet A standard 250RS would do a pretty good job though -- low seat height, relatively standard geometry, wide bars (at least by today's standards). Engine probably a bit revvy though.

I might have to find some TT100s then. Shame they don't do something suitable for the front (90/90, 3.00). Seems they used to, I've seen photos of skinny-tyred 125s in the 70s wearing them.

[Ixion]

3.00 is actually a 75/75. Near impossible to find slim enough tyres nowadays, everything is huge and designed for trucks.

Odd, I'm so far away from standard, a much wider front tyre and a much narrower rear tyre than what Honda wrote is what feels best. Perhaps Motu's onto it when he says front & rear same size. Then again I've never tried an actual 3.00.

TT100/K70 are `vintage' tyres for things like A65s and T120s, right? Surely they didn't have 4.10 fronts. Is 3.00 particularly uncommon? What do the Goldies/Velo Thruxtons run at the classic racing if not slicks?

I mean it shouldn't be that hard, BT45s `sort of' fit, but `sort of'... well...

[Ixion]

3.50 front, 4.00 rear was the norm back in the day. 4.5 for high powered machines.

3.00/3.50 for 350s , some 500s. Little bikes went down to 2.5/300, even 2.00/2.5.

Same size front and back wasn't that uncommon, often a 3.50

The fractional sizes weren't around much then , if at all. I never encountered them.

I always ran Avon Speedmasters back in the day, if I had a choice , I never like Dunlops.

I have this same problem with thew arzhole, I just can't get small enough tyres.
