EFFICIENCY AND BEAUTY COMBINE TOGETHER IN THE NEW 2011 SHERCO
In 2010 Sherco conducted a thorough renovation of their new trials models, introducing a bike with new concepts and ideas that was the beginning of an entirely new way forward in trials design. The new 2011 Sherco trials models are a clear example of this but they have now moved the concept forward, having built on the experience achieved after a year in the most demanding competitions with their top riders.
The big news with the 2011 Sherco is that it will have a new engine. This engine has completely re-designed housings in which there is an integrated cooling system ‘water intake,’ thereby eliminating the outer tubes to gain in reliability, whilst reducing maintenance – always a big consideration with all Sherco models.
The new crankcases are die -cast and machined aluminium in a single cycle, following Japanese technology, for superior quality. This ensures maximum accuracy of location points and tolerances. The new engine design allows a major change in the reed valve with a new position and a reduction in the external size of these parts. The clutch system has a new master cylinder, hose and slay cylinder, making it altogether smaller in size.
The fuel tank has been re-designed and manufactured in a thicker ergal alunimium (1.5-2.0 mm) and is welded not fused with an internal brace. The fuel cap is now in a more secure place centred in the middle of the rear fender which also provides ease for re-fuelling. Introduced in 2010 the supply of fuel to the carburettor is by a double internal circulation flow fuel pump, ensuring constant flow in all circumstances. The 290 model will be equipped with the Dellorto VHST flat slide carburettor as used by all team riders in 2010.
The air filter box has been revised with a new intake pipe and a new cover with a fastening clip system that improves the closure and sealing of the air filter box cover. The changes have not affected the air filter access and maintenance but have improved the air flow, allowing more cooler air to enter. This in turn allows the engine to rev much harder at the top end. The inlet nozzle has had minor changes to improve the airflow to the carburettor.
The tubular frame has the same dimensions but minor changes to the front of the frame have been made to relocate new panels. Along with this the steering also incorporates a hard plastic steering stop. The chassis is now in a striking white, which entirely compliments the new design plastics. The new 2011 models have a beautiful new aesthetic finish, based on the brands corporate colours of blue, yellow and white. The gold rimmed wheels finish off what is a very exciting, new model from Sherco for 2011.
The new model is expected to arrive in the UK by the middle of September and we will bring you the prices just as soon as they are available.
