The Storm 3D X-M 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 3D X-M's 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 X-M version will deliver 15%-20% extra mileage compared to the current Storm range. The wet weather performance of the Storm 3D X-M is outstanding, thanks in part to the tire's Super-Rich Silica (SRS) compound. The extremely high silica content delivers optimum grip in both the wet and the dry. It also has the added benefit of warming up quickly. The Enhanced Aqua Flow (EAF) pattern of the rear tire also increases your safety and confidence in wet conditions. With all this and together with many other unique-to-Avon technologies it is no wonder the Storm 3D X-M has gained numerous approvals from a tough German testing organization.
