Hi all,
Today I had a talk with a friend about the corsa engine in the RGS Corsa/SFC1000 bikes..
My claim is, that Laverda installed forged pistons in these engines. Something not used before that point. As far as I know the high comp pistons in earlier models, like the Jota120 are cast items.
Is that correct?
And I also claim that forged pistons are used in high comp/turbo applications, as they can withstand more heat and higher stress, where as a cast item may for example shred it's Crown off. Also I am under the impression, than once warm, a forged piston wil be more precise because of less expansion (note: after Warming up) and have a harder and stronger denser surface, hence the ability to move rings a bit more upwards as the ring land (or whatever it's called) are less susectible to melting/welding with the rings, giving the posibility to make shorter skirts and less weight?
Am I correct?
Okay, now it's up to you Guys to throw your take on this in here!
Kind regards,
Jacques
