British-based Avon Tyres has extended its Cobra motorcycle tyre range, introducing four new sizes to suit the latest Harley-Davidson Big Twin model updates.
There are two new front fitments, 130/60 B19 AV71 and 130/60 B21 AV71, suitable for the Street Glide and CVO Breakout models, among others. On the rear, riders can now choose the Cobra in 160/70 B17 AV72 and 180/55 B18 AV72 sizes. Avon has a long history of producing motorcycle tyres in custom and cruiser fitments. Its Cobra range combines the super-tough construction necessary for heavy-duty custom loads, with sports tyre technology for improved handling and performance. Avon’s Cobra tyre is renowned for its outstanding mileage and long life.
Featuring the distinctive Cobra tread pattern, the new fitments also sport the unique Cobra 'snakeskin' effect sidewall logo. Products from the Avon motorcycle range will be on display at the Motorcycle Trade Expo (14-16 January), taking place at Stoneleigh Park Exhibition Centre, Warwickshire.
The recent replacement of the long-running Avon Storm sport-touring tyre range with the new Spirit ST hasn’t marked the end of the line for the Storm. Avon Tyres reports it has developed a new Storm Endurance motorcycle race tyre, and this has already gained its first competitive victory courtesy of Neate Racing’s win at the Spa Classic 4 Hour race in late June.
When it comes to testing tyres, the motorcycle industry has for a long time recognised that Motorrad Magazine are the leaders in their field.
Their expert independent test riders score all tyres in a number of areas, covering performance in both wet and dry conditions. Recently it was the turn of classic tyres to come under scrutiny, and we’re pleased to report that Continental were the runaway winners of the test with the ContiRoadAttack 2 CR and ContiClassicAttack radials – a remarkable 20 points ahead of their nearest rivals!
Avon Tyres has introduced the all-new StreetRunner range of smaller-sized motorcycle tyres for the learner and commuter market. The tyre maker says the StreetRunner is specifically engineered for entry-level bikes that offer less power, but require great tyres with excellent grip, good mileage, nimble handling and strong stability.
Specially designed for 125cc-class machines, the new Avon StreetRunner comes in a range of sizes, including OEM size options for the Honda CBF125 and CBR125, and Yamaha’s YBR125 and YZF125. Avon reports that the StreetRunner’s grippy compound is optimised for wet weather and urban performance, while an all-new tread pattern clears water effectively and helps tyres warm-up fast.
Avons new StreetRunner will be produced August 2015
Urban motorcycle tyre for small 125ccm city bikes like Honda-Modell CBF 125 and CBR 125 or the Yamaha YBR and YZF 125

EIGHT BRANDS, 11 MODELS, TWO CATEGORIES - This time eight tire manufactures stepped up to the plate, including Avon, Bridgestone, Continental, Dunlop, Michelin, Metzeler, Pirelli and Shinko. We asked each to submit one or more samples of its current sport rubber designed for highperformance street riding (not racing) in 120/70-17 front and 190/55-17 rear fitment for a 2014 Suzuki GSX-R1000. We then divided the models into two categories: ‘A’ and ‘B’. The A group are the premium, top-of-the-line tires in each manufacturer’s respective line-up, while the B group represent a more affordable, but still capable sport tire solution.
PIRELLI DIABLO SUPERCORSA SP "This is the tire. The first thing I noticed is how tall the rear tire was. It really modifies the dynamic of the motorcycle. It puts more weight on the front and helps its steering response. What more can you ask for? Immediate warm-up time, incredible Velcro-like grip through all parts of the turn with loads of that precious feel that makes you want to push the bike harder. My favorite tire of the bunch and the one that I’d mount on my bike for performance riding."
120/70 ZR17 (58W) DIABLO SUPERCORSA SP V2
190/55 R17 (75W) DIABLO SUPERCORSA SP V2

Avon Tyres has launched a new, user-friendly website with an educational, practical and enjoyable, remit aimed squarely at us bikers. The re-vamped site should help motorcyclists find the right tyre for their motorcycle via the product finder.

Avon Tyres, a top quality brand of Cooper Tire & Rubber Company, introduces its exciting new range of sports motorcycle tyres, the VP2.
With Avon’s enhanced construction methods and its debut use of multi-compound rubber construction, VP2 looks certain to continue the successes of the acclaimed Viper range.
To cater to the demands of today’s multi-discipline riders and the vast array of performance machines available, both new and used, VP2 is offered in three different types; Sport, Supersport and Xtreme, all in a variety of popular fitments.
Though individually characterised by their own performance criteria and capabilities, the VP2 family shares the same key underlying aims; to allow riders to get exactly what they want from their machines.
With a rapidly evolving performance cruiser market, Avon Tyres, a Cooper Tire & Rubber Company brand recognized for its heritage and top quality tyres, have listened long and hard to what their cruiser, custom and touring customers demand from a tyre. Handling, durability and aesthetics were high on the list. So when it came to replacing the extremely popular Venom-R, Avon has more than met these requirements with an exciting new tyre range called Cobra.
With its unique snakeskin sidewalls, aggressive tread pattern and low noise emissions, Cobra silently defeats all roads that stand in its path. While performance figures and the weight of custom cruiser and touring bikes continue to escalate, Cobra is a tyre that coils around these opposing attributes to allow the rider to exploit them like never before.
Avon is to launch a new sport-touring tyre range named Storm-ST, replacing its highly popular Azaro-ST product. Storm-ST has already been tested and approved for fitment to all major motorcycles in conjunction with the well-respected German TUV agency.
Available from Autumn 2006, Storm-ST is available in 15 sizes:
Fronts AV55 - 110/70ZR17, 110/80ZR18, 120/60ZR17, 120/70ZR17, 120/70ZR18, 130/70ZR17
Rears - AV56 150/70ZR17, 150/70ZR18, 160/60ZR17, 160/70ZR17, 160/60ZR18, 170/60ZR17, 180/55ZR17, 190/50ZR17, 200/50ZR17.
Storm-ST is the first tyre to include Avon’s new ‘Reactive Footprint’ [RF] technology.
Reactive Footprint technology marries Avon’s unique variable belt density [VBD] carcass with Lifetime Profile Engineering [LPE] to produce a footprint which changes size and shape, depending on the bike’s lean angle, for the full life of the tyre.
The result is a contact patch that grows as the bike leans, giving more grip in corners whilst minimising wear rates when travelling in a straight line.
This technological breakthrough could eliminate the need to use dual compounds and would help solve the uneven wear problems associated with them.
Pete McNally, Avon’s Motorcycle Product Manager explained, “These new technologies combine to make a tyre that doesn’t just handle well when new but also in the last 25% of its life.” He continued, “With Storm-ST it’s not just the compound that’s harder in the centre and softer at the edges, it’s the whole tyre. We believe we are the first manufacturer to produce a reactive footprint tyre for motorcycles.”
In addition to Reactive Footprint technology and Lifetime Profile Engineering, Storm-ST is bristling with an impressive array of advanced features:
A new Super-Rich Silica compound [SRS] delivers sure-footed grip in both wet and dry conditions and allows the tyre to quickly warm up to reach optimum working temperatures.
‘Inverted Front Grooves’ (IFG) on the front tyre, a system pioneered by Avon in the late eighties and only now being adopted by the competition, resists ‘stepped-wear’ and ‘cupping’ to deliver smooth handling throughout the tyre’s life. A further advantage of the IFG configuration is improved wet braking and shorter stopping distances.
