This is a fine brochure dealing with common maintenance of one of the best motorcycle. One must realize it was written more than fifty years ago and it can not be compared with the modern Hayne's maintenance books with those coloured pictures, lots of tables and so many useful details.
Anyway, Vincent owner's handbook is good for everyone who admires and loves these splendid bikes.It is easy to read
Still, there is one remark I would like to mention : the quality of paper is poor. Such a bike deserves much better material.
