We had a Fell pony who absolutely hated motor bikes . She was totally bombproof in every other way and with all other vehicles from bicycles to roaring , back firing sportscars to combine harvesters passing within a hairs breadth , but she couldn't stand motorbikes . Fortunately my OH was the proud owner of an enormous Harley Davidson V Rod so one summer we took it upon ourselves to desensitise her once and for all . It took hours and hours of work over many months before I could finally ride her around the field whilst Mr Farside rode alongside on Pearl ( his motor bike - another long story ) . He could weave around her , revving the engine , and we even had a pillion passenger feeding her treats .
Success ? No . What I discovered on my return to the roads was that she still went bonkers at the sound of an approaching motor bike - unless it was a V Rod , in which case she would pull my arms out in her desperation to follow it .
