Only italian part on it will be the Veglia rev counter. There are quite a few of them in the USA and Canada and I know of 7 in the UK that were registered in 1980 and 1981, just before our law changed to outlaw Right hand sidecars fitted to bikes registered after July 81. I have one.
Nevals shipped most of their stock to Canada and some made it over the border. Based on the MT10-36 with an MB650 drive and sidecar chassis. The tub is a civvy one.
Neval bikes are usually easy to recognise due to the marked MPH speedometer with a prominent 55MPH position marked in red . Some have the Italian tachometers, some do not.
Easy to get parts for. MT16 for the sidecar and drive , MT10-36 for the bike but note that as the drive was military based, it does not support a sidecar brake.
Neval BMW/MT11 800cc hybrid, Neval 2wd MT10-36, Neval MT16, another MT11, BMW/MB650 hybrid and a K750m
