The circuit has pulled the plug on 19 of 23 bike track days set for 2009 following an order to cut noisy events from 140 a year to just 40.
Circuit Manager Tracey Morley told said : “There has been an adjustment to our calendar and sadly events have had to be cancelled.”
She said race meetings had also been cancelled and that more details would be released next week.
The axed dates had been organised by track day firms No Limits and Hottrax. Both said customers had been offered alternative dates.
Hottrax’s said: “We had 11 dates at Croft and we’re now down to two. It’s our favourite circuit to work at so not good news for us.”
Croft lost an appeal in January against an order to pay three local residents up to £150,000 compensation over noise.
Richard Jones QC, representing Croft Promosport Ltd, told the Appeal Court the ruling exposed the company to an "uncertain number" of claims from other neighbours and had serious implications for its future.
