I have had a 1300, a 2000 (carb), and a Volumex, but I agree that the 1600 is great fun. Lots of pep and buzz. Try it with digital engine management for even more fun. I have not tried the other Beta engine sizes or an injected 2000. I have a 1756cc Lampredi in a Fiat (badged 1800), and that is great.
It's definitely summer because in my garden you can put your foot on seven daisies.
Also, recreational driving is not banned, so vroom, vroom. Today I am having a huge faff trying to get my old Italian motorbike on the road. I may give up and go off in my Beta.
