The early 1990's are when Klein really went wild with the paint.  They used quite a few vibrant colors and lost of fades.  Many of the neon colors have lost their "pop" since the pigment isn't as durable (the neon colors are kinda hard to photograph and are much more vibrant in person).  This one appears to have held up nicely and uses the Klein specific bottom bracket, headset and bar/stem combo.
