Between Thursday May 17 and Monday May 21 a garage at a house in School Hill, Findon, was burgled.
Two motor cycles were stolen, one a Harley Davidson Night Rod Special, registration HX57CGG and a Yamaha RD350, registration VMX135Y.
They are valued at some £6,000 to £7,000 each.
Detective Constable Andy Hobden said; “We believe it is highly likely that a transporting vehicle of some kind would have been used to out the motor bikes on, possibly some kind of load loader or a flat bed.
“The offenders would have had to go past neighbouring houses to get away and therefore probably would not have risked starting up a motor bike, especially a Harley Davidson, due to the noise. it is more likely that they have wheeled the motorbikes to an another vehicle”
“If anyone saw two motorcycles on the back of such a vehicle around the Findon or A24 area between these dates or any other suspicious activity, please contact us on 101 quoting serial 1236 of 21/5”
