Having owned Guzzis, Benellis, Ducatis and Laverdas - Certainly amongst those I had, the Laverdas were without doubt the best made. Their castings were top notch. Unlike pretty much all the other Italian marques then they used Bosch and Nippon Denso electrics. And the bits inside were well made - But they had to be maintained.
And that last bit was the cruncher back when I used 2 wheels for ALL movement. I was younger, less patient and reluctant to pay/trust others. And my then mentor was a native of Mandello del Lario and knew where and how the get and do everything to Guzzis.
But I could not fit onto the big Laverdas. They were simply too big. And it's a shame or I would have bought a 120° crank RGS. I wanted to so much.
There were only about 250 ever made of the models I had. The Montjuic.
Basically a 100% track bike 500cc twin and 60bhp - which in 1981 was no mean feat. But 18,000€ is plain silly for a used one.
The only bike I ever rode that was comparable was a Gilera Saturno Bialbero.
tbh I hanker for something along the same lines - but NOT a retro styled thing. But we cannot have everything we wish for.
I am torn right now. Part of me says "Buy something (new) that will be allowed into Madrid on SMOG alert days". Another part says "F*ck Madrid - Build a nasty antisocial little 500/600 and .................". The last part says " Get a dog, buy slippers and learn to smoke a pipe - build a steam engine".
