Secondary travel and tour channel Rotas e Such: / @rotasetal It's not news that engines are losing power, recently, the Honda bros 160 and cg 160 came to prove this. Emissions standards are increasingly in place, requiring an increasingly poor air-fuel mixture, which brings less power and greater heat to the engine. All this, added to the low compression ratio in air-cooled engines, will cause manufacturers are forced to abandon this type of cooling, adopting, as we see on imported motorcycles, liquid cooling, which brings greater durability and performance.
