The Zephyr Zone

well im really looking for a classic kawa 4. the zephyrs seem pretty cheap and the aftermarket looks good and the offerings from doremi to make it look like a Z2 appeals to me. Im mainly worried about corrosion, what makes these so prone to rust? did they just use a cheap metal or something? Can one...

im considering one of these along with a z900RS or zrx1200R for my next bike.

Do the frames really rust as bad as some people claim? I know the tanks seem to but i'll be replacing that with a doremi Z2 tank.

any other problems with these?

wondering as well
