I've got about 300 miles on a new Avon Storm ST. Here's the "scoop..." (ST=Sport Touring)
The long-lasting, all-weather, high performance sports touring tyre.
* Incorporates the very latest bike tyre technology 'Reactive Footprint'. The tyres contact patch changes size and shape depending on lean angle - for the life of the tyre
* Unique construction means excellent performance combined with very long life
* 'Super-Rich Silica' rubber compound gives superb wet road grip
* Front tread pattern optimised for shorter stopping distances in the wet
* Excellent stability and handling whatever the lean angle

The Storm-ST replaces Avon's Azaro-ST and builds on its predecessor's talents. Employing what's called 'Reactive Footprint' (RF) technology, the Storm-ST produces a footprint that changes size and shape depending on the bike's lean angle, growing in size the further over the bike goes. It means you get high grip through the corners yet in a straight line have a footprint which increases the Storm-STs lifespan. Avon's RF Technology is a quantum leap in technology from the dual compound tread, and will provide unparalleled evenness in wear patterns.
The wet weather performance of the Storm-ST is outstanding, thanks in part to the tyre's Super-Rich Silica (SRS) compound. The extremely high silica content delivers optimum grip in the wet and dry. It also has the added benefit of warming up quickly.
On the front tyres, the Storm-ST benefits from Inverted Front Grooves (IFG) that resist stepped-wear and cupping, ensuring smooth handling for the life of the tyre and improving wet weather braking. The Enhanced Aqua Flow (EAF) pattern of the rear tyre also increases your safety and confidence in wet conditions.
With all this (together with many other unique-to-Avon technologies) it's no wonder the Storm-ST has gained numerous approvals from the tough German testing organisation, the TUV.
