Akso what is the connection betwwen Collari. Picco & Sirio? I know Collari are based on Picco, is it the same for Sirio or are they nova based?

The latest model from Sirio, the S12TRP "Evo2" is comparable in performance to the latest Nova based engines, it has a killer top end and is very easy to tune, very stable, and withstands high temps easily. I have one, and I'm very satisfied with it. It delivers its power at a higher powerband than the nova based engines, but when properly geared and with appropiate pipe IT IS A BOMB.
The L.Collari (Innotech)company started with modified Piccos, but now they work over Rossi engines.
The M.Collari company works over Sirio engines. Check this site:
