The cooling holes under the exhaust, 3 weight inserts and even a groove in the upper lip of the sleeve. I would say Novarossi is copied very well.....

Roelof, I guess now that the old Nova is no more, and as such I am not sure who now has the rights to patent / design / copyright etc. I am sure they will try more of the Novarossi "black magic" lol
