Agreed on both points. In their defense of utilizing plastic, the 500 and 750cc LC models are aimed at entry level buyers and are made and priced accordingly. I wonder if the intended audience is India and the domestic market was an after thought. BTW, while these models are made in India, the domestic supply is purportedly assembled in KC Missouri.
Regarding the power output, all I can say is they have left themselves some room for growth in subsequent model years. I see they are only single overhead cam which is still a departure for HD. I'm not sure if they are 2 or 4 valve heads - I'm guessing 2? Being over square these engines likely have a very different power delivery compared to the traditional HD layout. Having said that they may have sacrificed high RPM power for midrange grunt.
