The 25th annual Vincent County Rally, run by the Biker Rights of New Zealand Otago branch, attracted about 1600 people to the Manuherikia River site at Galloway.
Branch president Ron McKay said this was despite there being almost no advertising or promotion of the rally.
‘‘Every year we just send entry forms to people who came to the previous year's rally and that's all we have to do,'' he said.
About 800 people camped on site on Friday night and double that number the following evening.
Nothing special had been planned for the 25th ‘‘birthday''.
All types of motorcycles, including choppers, trikes, road and trail bikes were on display.
Mr McKay said the organising committee believed in ‘‘buying local'' so service clubs and community groups were invited to provide the catering at the rally and local products were sourced.
Some of the proceeds from the event went back to keep the club afloat. The rest was donated to the Muscular Dystrophy Association.
Last year's donation was about $6000. Petrol stations, cafes and restaurants all received an economic boost from the event.
