Match on DVLA site, therefore the bike is on the DVLA database and therefore may well still exist. Appears it was last taxed in 1993. May have been exported ?
Logbook shows body type as Canterbury so looks like it had a chair on it at some point.https://www.ebay.co.uk/itm/ARIEL-SQUARE ... ctupt=true
