ATTENTION!! Due to the situation in the Ukraine, we're having problems maintaining tyre stocks, and we're faced with rapidly increasing prices—which we're not happy about passing on. So no more orders until further notice. Sorry, but we have to face certain realities.
Avon AM9 (Roadrunner)
● Free delivery!!
● New tyre construction
● Enhanced sidewall design
Classic bike tyres | Avon | Continental | Dunlop | Metzeler | Michelin
Officially, this tyre is listed as an AM9. But plenty of people, both classic bikers and mainstream bikers, simply think of it as the latest incarnation of the Avon Roadrunner. And that's pretty much how we see it.
The grip is good in the wet or the dry. It's a fairly hard compound, so it wears slowly when compared to some rivals. And we haven't experienced any significant squaring off.
But there's only one size available (at the time of writing), which is the listing you see on the right. We're currently running two Triumph T140s with this rubber, and we're very happy with what we've got. If you're looking for a suitable rear, you might want to check out the other Avons that we're offering (see further down this page). Or try a 4.25/85 - 1864H K81 Dunlop K81 TT100. And when you do find what you like, order immediately and we'll send you what you want to help keep you on a roll.

WARNING!!!
Top advice before buying motorcycle tyres
How do you know that the tyres you're buying are safe to use? That's a tricky one because tyres have to not only be correctly manufactured, but they also have to be properly stored prior to sale and use. And not all stored tyres are fit for purpose.
We're not just talking about the usual knock-off rubber coming in from the Far East and flogged on the 'net. We're talking about tyres that have, perhaps, been legitimately bought from wholesalers, but then badly stored.
That can mean exposure to too much sunlight. Incorrect racking. Over-long storage. Incorrect temperature control in storage. Chemical damage when in storage. And there are many other potential hazards including delamination, cracking and general decay. Therefore you need to feel confident in the people you're buying from—and that means staying clear of the dodgy dealers and suchlike on the internet.
If you buy cheap—or too cheap—you could be buying a lot of trouble. At Sump, we deal only with a reputable wholesaler. We set a fair price and we stay competitive—with everyone but the dodgy dealers. So either trust us with your business, or don't.
We're constantly looking out for tyre trouble so that you don't have to ride straight into it. And if you've got any doubts or qualms, we want to hear about it asap.
Okay?

The first time you have to use this kit, it will convert you to Christianity—or maybe some other religion. Either way, you'll be grateful to someone. Or something. Of course, this won't suit classic bikes with inner tubes. It's purely a tubeless kit—and pretty much everyone with tubeless tyres should have one. What's that? You've already signed up to a breakdown service? Well great. The last time we waited for a recovery van to show up, it took three hours.
Click on the image above, or fish around for a link, and you'll get a bite from our Puncture Repair Kit Buying Page. We wouldn't leave home without one. You shouldn't either.

WAITING FOR YOUR SUMP ORDER?
If you've recently bought a Sump T-shirt, a book, a motorcycle lock, a framed print, a tin wall sign or whatever, and if your order hasn't arrived, you might want to check your email spam box. We regularly find that customers have failed to give the information we need to process the order (size, full address, style, colour, etc).
If there's a query, we make three attempts to contact buyers, and if we get no reply, we cancel the order and return any payment. But that can lead to disappointment, especially if the item 
is a gift for someone. So if you haven't heard from us within 24 hours of placing your order, please check your spam box, or contact us again.
