The Storm ST has already been tested and
approved for fitment to all major motorcycles in conjunction with the
well-respected German TUV agency.
The Storm ST has been launched (Fall 2006) and it's available in 15 sizes:
Front Tire AV55: 110/70ZR17, 110/80ZR18, 120/60ZR17, 120/70ZR17, 120/70ZR18,
Rear Tire AV56: 150/70ZR17, 150/70ZR18, 160/60ZR17, 160/70ZR17, 160/60ZR18,
170/60ZR17, 180/55ZR17, 190/50ZR17, 200/50ZR17.
Storm ST is the first tire to include Avon’s new "Reactive Footprint"
technology. This technology marries Avon’s unique variable belt
density carcass with Lifetime Profile Engineering to produce a footprint which
changes size and shape, depending on the bike’s lean angle, for the full
life of the tire.
The result is a contact patch that grows as the bike leans, giving more grip
in corners while minimizing wear rates when traveling 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
Pete McNally, Avon’s Motorcycle Product Manager explained, “These new
technologies combine to make a tire 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 center and softer at the edges, it’s
the whole tire. We believe we are the first manufacturer to produce a
reactive footprint tire for motorcycles.”
In addition to Reactive Footprint technology and Lifetime Profile
Engineering, the Storm ST is bristling with an impressive array of advanced
features, including a new Super-Rich Silica compound delivers sure-footed grip in both wet
and dry conditions and allows the tire to quickly warm up to reach optimum
"Inverted Front Grooves" on the front tire, 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 life of
the tire. A further advantage of the Inverted Front Groove configuration is improved wet
braking and shorter stopping distances.
The Storm ST rear benefits from Avon’s Enhanced Aqua Flow pattern, first
used in sportbike tires, which rapidly clears away surface water to
further increase confidence in the wet.
Also developed for sportbike tires and now built into Storm ST is Avon’s
Advanced Tread Arc Combination 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 heavy braking
Finally, all components are fine-tuned by Avon’s Enhanced Stability System to deliver a tire in which the carcass, sidewalls and tread
pattern work together to reduce localized flexing within the tire structure
to optimize grip, durability and warm-up capabilities.
