Ben Walker, international director for Bonhams collectors' motorcycle department, said: “When choosing which motorcycles to feature we’ve tried to select machines from across the collecting spectrum - from the early Pioneer period with the 1908 Triumph 3½hp Combination through the post-classic 1990 Honda VFR750R Type RC30.
"These are machines that will appeal to all areas of enthusiasm – not just because of their value but also because of the nostalgia that they evoke.
“It's fascinating to see how the values have increased since the machines were new.
"Knowing what we know now – the percentage increase in value and how difficult it is to acquire these machines - it would be great to step back in time and buy them when new.”
