Banner
ATHENA high performance kit with exhaust valve! This guillotine valve, as on certain YAMAHA, ROTAX and other engines, allows the exhaust diagram to be lowered at low speeds to have maximum torque, and to gradually increase it at high speed for maximum power! Otherwise, the parameters speak for themselves, large compression ratio, fine mono-segment piston, cylinder head ... We are on a very powerful 50cc kit! Ideal on a cross or enduro machine which must respect the displacement of 50cc!
As an option we offer a stage 1 preparation, this preparation is a modification of the channels and the exhaust port by increasing the diagrams and improving the duct, it increases the performance of the cylinder. An improvement to the piston and the bottom of the skirt is also included in this modification. Allow a little extra time for this preparation!
