Avon Tyres has announced the new Viper range of motorcycle
tires, designed for sport and super-sport motorcycles. The tires are
now available in North America for 2005.
The Avon Viper builds upon the success of previous Avon
ranges and offers a wider choice of sizes and a host of improved
The Viper Sport is available in 11 sizes:
AV59 Front: 110/70R17, 120/60R17, 120/65R17, 120/70R17, &
AV60 Rear: 150/60R17, 160/60R17, 170/60R17, 180/55R17,
Drawing on Avon’s years of experience the new Viper Sport
pattern has been designed to reduce localized flex points in the tread,
improving high speed stability. The Enhanced Aqua Flow (EAF) pattern rapidly
clears away surface water to increase confidence in the wet.
Viper Sport also boasts a brand new Advanced Tread Arc
Combination (ATAC) profile, which varies the tread profile across the tire
for the ultimate in handling and stability, whatever the lean angle. The ATAC profile results in neutral contours, ensuring smoother transition on
lean angle changes, and noticeably increases stability, especially under
The tread compound features a new ‘high dispersibility’
silica formulation (SIO2-HD) ensuring rapid warm-up times and maximum grip
in wet or dry.
In addition, Viper benefits from Avon’s unique Advanced
Variable Belt Density (A-VBD) technology, specifically for rear tires. This
is a jointless belt of ultra-strong Aramid fibers running round the tire’s
circumference. At the centre of the tread, the fibers are closely wound for
maximum stability and wear resistance. The closer to the edge of the tread,
the further apart the fibers are positioned, broadening the tire’s footprint
under cornering loads.
Finally, all components are fine-tuned by Avon’s Enhanced
Stability System (ES-System) to deliver a tire in which the carcass,
sidewalls and tread pattern work together to reduce localized flexing within
the contact patch to optimize grip, durability and warm-up capabilities.
Sharing the same pattern and core technologies, but with the
addition of a softer compound (Race-C) is Viper Supersport, available in
AV59 Front:120/60R17 & 120/70R17
AV60 Rear: 160/60R17, 180/55R17 & 190/50R17
Avon’s Race-C compound has been developed by test riders on
numerous roads and circuits around the world, and then refined to deliver
the optimum tire for fast road use and the occasional track day.
Both Viper Sport and Supersport feature an aggressive
snake’s head logo on the tread and sidewall of the tire.
