Roads will be closed in Aylesbury town centre this weekend - to make way for a gathering of bikers.
From 6am til 9pm on Sunday 11 May part of Exchange Street car park will not be open to the public.
Aylesbury Bus Station will also be closed from 7pm on Saturday until first thing on Monday morning.
All departures will use the stops on Great Western Street.
The road closures are to make way for Wycombe Motorcycle Action Group who are raising money for charity.
The club will gather at the Crown Public House, in Chinnor, riding in to arrive at Exchange Street car park at around 11am.
Numbers on the ride are variable and depend on the weather condition - but it is thought up to 200 riders may attend.
There will also be entertainment and refreshments in the Market Square from 11.30am until 8pm.
Revellers can enjoy live music from midday until 8pm on a stage opposite the court building.
