can't see as class A can be any more exspensive than it was when people were gearing up for the 2005 season.
Those buying a 620 at the end of 04 or begining of 05 were buying bikes that were 2 years old or less, some even buying new.

I'm sure I could now go and buy a 620 plus a slipper clutch for less than most paid for their 620s back then.

On the other hand Class B was introduced in 2006 as a cheaper alternative to attract newwbies to racing
