BETA 2011 EVO 125 details.

30th Sep, 2010 | David Ryan

The bike that won the Australian Junior boys and girls Titles in 2010 with Sam King and Adina Reed has had a major engine update.

The 125 engine has been completely revised.  A new piston profile, new crankshaft with lighter con rod increase power and reduce vibration.  A new combustion chamber shape combined with a new ignition advance curve enhances the increased power output.  The flywheel is lighter to reduce weight and inertia.  This provides easier handling and a more race ready bike.  A new silencer with revised internal components gives greater torque and power output. 


Beta 125 Australian Junior Boys champion in 2007, 2009 and 2010.  The winning machine has just got better.
