En moto GP son 4T, en 125 son monocilíndricas de 2T y en 250 son bicilindricas de 2T. Cuando se cambio la categoría de 500 a MotoGP, en el año de transición corrian motos de 4T de 900cc contra motos de 2T de 500cc. He oido comentar que una 900 de 2T sería imposible de conducir por la potencia que desplegaría.

Para trucar una moto de dos tiempos lo único que tienes que hacer es limarle los canales de admisión y escape y retocar el tubo de escape que traen de serie (ésto puede hacerse taladrando la cámara de expansión que traen) el incremento de potencia es sustancial, a cambio te arriesgas a una gloriosa agarrada de pistón. A un compañero de colegio (años ha) le vi un gripage de una 2T (una Puch) y el pistón le dobló el chasis.

En general, la equivalencia de cilindrada sería de 3:5 es decir una 75 de 2T sería equivalente a nuestras 125 y una 250 de 2T sería superior a una 400 de 4T, siempre que se trate de monocilíndricas. Si metes más "cacerolas" la cosa se equilibra.[/quote].


Vamos a ver yo no he discutido las diferencias de rendimiento entre 2t y 4t, ni tampoco los costes de mantenimiento, durabilidad, etc,podria abrirse un debate de esto, lo que planteo es que hay una equivocada cultura sobre los trucajes/potenciaciones en motores de 4t, que entiendo que se deben entre otras a la relación oferta/demanda lo que se traduce en encarecimiento y falta de rentabilidad ( también se podría hablar largo y tendido, porque parece que en 2t siempre es rentable y en 4t no), Finalmente y contestando a tu comparación de potencia hay que entender una cosa muy claramente y son las " vueltas de cigüeñal por cada explosión" en las que lógicamente sale perdiendo el 4t de ahí esas diferencias de resultado que comentas, pero eso no quiere decir que se pueda potenciar una 4t, desde luego con resultados " menos explosivos" pero también con más posibilidades de durabilidad de la operación, y ahí entraría también la " rentabilidad" de la operación, o no?
