Avon - Technically Speaking....

A-VBD (Advanced-Variable Belt Density)
Stands for Advanced-Variable Belt Density technology, specifically for rear tyres. This is a jointless belt of ultra-strong Aramid fibres running around the tyre’s circumference. At the centre of the tread, the strands of Aramid are very closely spaced for maximum stability, and high wear resistance. The closer you get to the edge of the tread, the further apart the strands are spaced - this broadens the tyre’s footprint when you’re getting you knees down.

   

ATAC-TA Tread Profile (Advanced Tread Arc Combination - Tri Arc)
ATAC varies the tread profile across the tyre for the ultimate in handling and stability however far over your bike is. Works in tandem with A-VBD.

   

EAF Pattern (Enhanced Aqua Flow)
Front and rear tread patterns are computer designed for maximum throughout of water within the tyre footprint. This propels water away from the contact part hence adding water dispersion and maximising wet grip.

   

ES Systems (Enhanced Stability System)
The carcass, sidewall and tread pattern are designed to work in harmony so that the stresses absorbed by the tyre are distributed evenly. This reduces localised flexing whithin the tyre’s structure. The result is an increase in grip and stability while at the same time reduces tread wear.

   
FFG (Force Following Grooves)
A new stylised tread design which balances the need for rapid water dispersal, tyre stability and
maximum resistance to wear. Deep cut grooves follow the forces being transmitted through the tread and carcass significantly reducing irregular wear.
   
Hybrid Belt
A world first. Ultra strong low extension steel wires of different tensions bound together to make a tape  component which is wound around the tyre at 0 degrees to form a unique belt system. This new belt produces exceptional high speed stability while the flexibility and natural spring properties of steel translates into exceptional mechanical grip. This is our most advanced belt system yet.
   

IFG (Inverted Front Grooves)
For the front tyre, a system pioneered by Avon in the late eighties and only now being adapted by the competition, resist ‘stepped-wear’ and cupping to deliver smooth handling throughout the tyre’s life. By significantly reducing uneven tread wear, a further advantage of the IFG configuration is improved wet braking and shorter stopping distance.

   
LPE (Lifetime Profile Engineering)
This works in conjunction with ATAC to produce a tyre profile and footprint which even when worn, gives consistent handling and stability for the full life of the tyre.
   

Race-C
Compounds optimized for track performance.

   

RF (Reactive Footprint)
Reactive Footprint technology marries Avon’s unique variable belt density A-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 long life when travelling in a straight line and more grip in corners. This technological breakthrough questions the need for dual compounds and solves the uneven wear problems associated with them.

   

S-Compound (Silica-Compound)

That’s ‘S’ for silica, an ingredient added to rubber for superior wet road grip.


   

SBC System
‘Spiral and Belted Carcass’. The Viper’s high level of grip puts high loads through the tyre’s carcass, the SBC System features ultra-tough belts underneath the Aramid fibres of A-VBD to cope with the extreme stresses. Rear tyre only.

   

SiO2-HD (Silica-High Dispersibility)

High dispersibility’ silica formulation. Silica-HD compounds have rapid ‘warm up’ times giving maximum grip in the wet and dry.

   

SRS-Compound (Super Rich Silica Compound)
Compounds formulated with large amounts of silica after enhanced grip in wet and cold conditions. This produces extra grip when the tyre is cold but also reduces excessive heat build up which can affect mileage.

   
TTE (Triple Tread Extrusion)
Three different rubber compounds are extruded into each tread.
Compound 1 - A durable medium compound in the centre of the tyre for improved mileage.
Compound 2 - A soft compound on the edge of the tyre for maximum grip at high lean angles.
Compound 3 - A very soft low hysteresis compound across the entire base of the tread to improve the bond between the other two compounds and the carcass.
