OLD BIKES
JAWA, A world famous Czechoslovakian bike (all CTB bikes were JAWA 250 and 350 in seventies.) Later around late eighties Sathosa Motors got the dealership, but nobody bought this "STEEL BUFFALO" shaped bike.
ROYAL ENFIELD, The name itself tells you where it's made.
HARLEY DAVIDSON, An Amarican product since 1909 (not sure ), and to my knowledge they owns the patent rights for the distinctive ""noise"" that bikes make. That means, that sound cant be same as Harley in any other bike.
RAJDOOT, Again the name says it all.
