Prós e contras em comparação
Yamaha R7 2021
Apesar da combinação bastante idiossincrática da sensata unidade de potência de gama média de 73,4 cv e do visual extremamente agressivo e desportivo, a R7 não é de forma alguma uma ovelha em pele de lobo. O desempenho, que se situa algures entre a R3 e a R6, revelou-se muito mais forte na prática do que os valores puros no papel poderiam sugerir e, em termos de geometria, chassis, travões e pneus, os engenheiros da Yamaha fizeram realmente o seu trabalho de casa. Para além disso, a Yamaha R7 tem todas as qualidades para se divertir imenso numa pista de corrida compacta como Pannoniaring, por exemplo, mesmo sem um grande investimento. Mas é claro que ela se sente melhor na estrada rural, e é aí que ela pertence em primeiro lugar, em nossa opinião. Tendo em conta o pacote global, o preço de compra é mais do que justo - por isso não é um problema o facto de a alavanca de velocidades não estar incluída e ter de ser adquirida como opção.
Kawasaki Ninja 650 2017
A Ninja 650 é um selo firme da sua antecessora (Er-6f). O motor dominou bem a barreira do Euro 4 e oferece 68 cv muito úteis, o chassis é simplesmente fantástico para esta classe e a redução de peso de 18(!) quilos em comparação com a ER-6f justifica acenos de cabeça reverentes.
