Dad's response to any enquiry about owning a motorcycle was "I'll not be buying you one, or having anything to do with it!" And "Don't forget that there is the road tax and insurance to pay, as well!"
Riding a BSA M20 through Indian bush as part of his 'training' in the Signals, prior to the planned push into Japan had confirmed his jaundiced view of motorcycles. His Aunt having a James, Villiers engined 2 stroke in the '30's that required lots of "maintanence" started the loathing!
Having ignored all these protestations, I acquired an ex GPO D1 Bantam in a tea chest at the tender age of 13 and unbeknown to either my Mum or Dad, then assembled it and rode it all over the 'Common', being chased by the National Trust Forester!
Having survived all manner of small capacity Japanese, BSA and AMC bikes for 7 years, I acquired an AJS 18S in 1974 and Mum would happily sit on the pillion to go shopping! However, Dad stayed true to his word and never paid a penny towards, assisted or rode any of my bikes till the day he died. Once he realised he wasn't going to disuade me, he never harped on about it, but would comment occaisionaly about my sanity!

That's still open to debate now!

My regards, Bill
