The first 2012 World Superbike Championship race at Monza has been cancelled after concerns with the treaded tyres in wet conditions prompted organisers to play safe.

The race originally started in dry conditions but was halted after three laps when a brief shower brought down John Hopkins, David Salom and Sergio Gadea.

With intermittent showers at different parts of the circuit causing further havoc as the bikes lined up on the grid for a restart, an impromptu meeting on the home straight suggested the riders were not keen to head out onto an ever evolving track.

However, just as a handful of riders went onto a track inspection, the heavens opened properly and rain began falling heavily, a worst case scenario following the riders' pre-race declaration that they wouldn't be able to race on Pirelli's wet weather tyres.

Indeed, the riders have been vocal about the state of the rear wet weather tyres throughout the weekend, which have been quickly breaking up after just a handful of laps under the high-speed conditions.

With this in mind, organisers have taken the decision to cancel the race altogether, while the World Supersport race - which is scheduled to start at 12.30GMT - may also be canned.
