+1 on Egan...hard to go wrong there.
I occasionally pick up a copy of Motorcycle Classics, used to have a subscription but let it lapse (may have to reconsider that).
It is very well written/shot. I also like how they delve into not-so-old bikes on occasion.
2007 Bonneville T100 - Ricor Intiminators, Ohlins 36E's, TOR's, Burton DS003 and other geegaws.
