Does anyone know where I can find out the value of these bikes. My husband has the same model and he is thinking about selling it. Thanks

Re: 1990 Kastan KEX Pro-S
The value of that bike is very hard to determine. They are quite rare, and I think that bike really falls in to the " whatever someone is willing to pay for it" I would however say..... It is worth A LOT
Good luck
