Max Power XXL9 14.5 .21 engine

Max Power have introduced their new XXL9 14.5 engine. A completely new 3,5cc on road engine featuring a 14.5mm diameter shaft. Fearing all the improvements of the XL9 TQR which we covered last week, such as the reinforced crankcase, new piston & liner set with revised wrist pin height, and new wider/lower/lighter cooling head, the big performance difference between the two engines is that the 14.5 will have higher top speed. Together with XL9 TQR, this will be the engine the Max Power team will in Miami for the World championships in April.
