Honda began making the monkey bike with its high bars and robust little 49cc engine in 1968 and they were all the rage at the time.
So the hip Beatle bought one to ride around his Tittenhurst Park Estate in Surrey in 1969.
Now, his Honda XUC 91H will be sold through H&H Classics at the National Motorbikes Museum on March 4 at an estimated £30,000 (about $A52,000, $US40,000).
Imagine owning the bike Lennon once rode! I think I’d be a very Jealous Guy and would wonder if it inspired the song “Everybody’s got something to hide except for me and my monkey”. (Sorry about the appalling puns!)
H&H spokesman Mark Bryan says they are “thrilled to be entrusted with the marketing and sale of this bike, given its extraordinary provenance”.
We bet they are! No doubt some Beatle fanatic will snap it up.
End of Monkey Bike era
Old monkey bikes are expected to become collector’s items after Honda last year ceased production due to emissions issues.
