The book that Ty is reading when Jack comes to see him in Caleb's trailer is "Prairie Dust, Motorcycles and a Typewriter" by Greg Williams. This is a biography of a man named Bernie Nicholson who grew up on a farm in Saskatchewan during the first half of the 20th century and taught himself how to repair motorcycles. Nicholson wrote a manual called "Modern Motorcycle Mechnics" which sold more than 100,000 copies, went through seven editions from 1942 to 1974 and is still used by vintage motorcycle enthusiasts.
Jack's motorcycle is a red 1983 Yamaha XJ 1100 Maxim. It was not manufactured in Canada after 1984.
