I had an 03 Scorpa SY250, that was absolutly wonderfull!
They dont have linkage suspension so they are great for climbing hills, nice smooth power, we never had any problems with them, only ever had to clean the air filter after every 3 or so rides!
Such a nice set up bike too, the way everything is felt just spot on! Very narrow bike too.
In saying that, I also had a Montessa Cota 315, a '96 I think, that was awsome too, real small turning circle!
