Beginning with a James ending with a Honda

Finishing up the paperwork…
Mechanic:

 All set. Are you ready for the downsize from the CB 1300?
Old Timer: Smaller, but familiar. Learned to ride on a 125cc James two-stroke.
Mechanic: James? Heard of them. 
Old Timer: Vintage, with the gear shift on the tank.
Mechanic: Why the bright yellow on this one? Bold choice.
Old Timer: Visibility. Safety. This is probably my last bike. 
Mechanic: This one's joining your legacy?
Old Timer: The final chapter.

Winston Churchill’s last bike was a James. Maybe he was visible enough on it not to need yellow.
