With its unique snakeskin sidewalls, aggressive tread pattern and low noise emissions, Cobra silently defeats all roads that stand in its path. Construction: Advanced manufacturing techniques used in Avon's successful sporty Viper range have been adapted and applied to Cobra: WCTA - Wide Custom Tread Arc - is Avon's new tyre profile that gives Cobra a nimble characteristic once reserved only for agile race-bred bikes, all without disrupting all-important stability. A-VBD - Advanced-Variable Density Belt - improves handling in the much wider Cobra sizes. This construction technology utilises a jointless belt of ultra-strong material. Above the carcass, these strands are wound closely together at the tyre's centre for increased stability and wear resistance. Towards the tyre's edges the fibres are then progressively spaced out to allow the tyre to take on a multi-compound effect as the tyre leans. Tread Pattern: An aggressive tread pattern features FFG - Force Following Grooves - to follow the exact direction of forces that are transferred through the tyre. These channels in the tyre's surface significantly reduce irregular and advanced wear on bikes that carry heavy loads. Each Cobra rear tyre also features the distinctive snake's head logo on the sidewall.
