WOW that CBR-250 looks ultra clean...if its in the same condition as in the pic and the engine is also 100% ...so keeping in mind that the bike is Custom Clear but Unregistered 1993 model it should be around 85,000 to 100,000....I would again say if its in the same condition as in the picture.
A 1996-97 Model CBR 600 would cost you about 225,000 to 300,000 depending on the condition.
