Bill Smith Motors of Chester was broken into early on Sunday morning and police are appealing for information and footage from members of the public.
Shortly before 1am, 8 September, six people on three motorcycles rode up to the dealership on Tarvin Road in Boughton.
The offenders broke into the premises using a sledgehammer and stole two Yamaha Sport Touring motorbikes.
They towed away the stolen bikes – an MT-09 SP in black, silver and blue and an MT-10 in matt grey – in the direction of Vicars Cross.
The six offenders were all wearing dark clothing and motorbike helmets and appeared to be males.
DC Nicky Edgell, of Chester CID, said: “We are determined to identify the offenders and make them face the consequences of their actions.
“We are also doing everything we can to recover the stolen motorbikes and have them returned to the dealership.
“Enquiries are ongoing and we want to hear from anyone with information regarding the two stolen Yamahas. They did not have a battery or fuel in them so they may have been left nearby.”
Anyone who can assist should call Cheshire Constabulary on 101, quoting IML 507628, give the details via cheshire.police.uk/contact/general-enquiries or contact Crimestoppers anonymously on 0800 555 111.
