Tina and Scott Honeychurch have been forced to clean up after thieves for the fourth time after a four-wheel-drive ploughed into their family's Legana business in the early hours of Monday morning.
Mrs Honeychurch said the thieves got away with a new motorcycle and caused major damage to others.
"We probably have three brand new motorcycles written-off," she said.
"The bikes were all smashed, laying on top of each other. It was all chaos."
The business was so badly damaged, a mammoth clean up effort was required in order for it to begin trading again.

"We spent all day and night cleaning up," Mrs Honeychurch said.
"We had to pay the staff for the day to clean up the premises."
In the 14 years her family have operated the business, Mrs Honeychurch said they'd been broken into four times.
"One they did two nights in a row," she said.
"They don't realise what they're doing to small business. It can just about break you."
She said while she was frustrated by the "scum" who targeted her business, support from the community helped soften the blow suffered.
"They [courts] need to come down on them [thieves], they all seem to get away with it," she said.
"We were just so overwhelmed with the support from customers and friends, we really appreciate it."
Tasmania Police confirmed an investigation into the incident had commenced.
"Police are investigating a burglary and damage incident at Scott's Motorcycles on West Tamar Highway at Legana around 3.50am yesterday morning," a spokesperson said on Tuesday.
"A white Nissan Patrol without registration plates reversed through the glass sliding doors of the business causing significant damage. A white FE 501 Husqvarna motorcycle was stolen."
