For future reference my brother got a puncture 1 mile from the ferry in Portsmouth
The other end there is a Guzzi Aprillia dealer we phoned ahead from the boat to book it in
Managed to inflate it enough to get from the ferry to the dealer 1/4 mile on the road out of town by the station
All sorted in about 3 hours and back on the road
Thank you- let's hope I never need it!!
