1992 Yamaha Seca II (XJ600)  
Most of the rides on Colorado Motorcycle Rides.com feature photographs of my XJ600.  I have received questions about it and often get people asking about it when I'm out riding.  I've created this page to provide some more information on this bike.
 
This is a 1992 Yamaha Seca II (XJ600S).  I purchased it used, in 2009, for $1300, as pictured below.

Unknown to me, at the time of purchase, the bike had been laid down hard on its right side.  I began stripping the paint down to repaint it and found 2" of body-filler in the tank.  When that was removed, I realized the handlebars had dented the tank badly enough to dent it through the inner skin.  The steering stops on the triple, made of cast iron, were also badly bent.  Since I had purchased the XJ600 to replace my XS400, I decided to convert it to a traditional naked-style bike. 
 
My first attempt, while good, was not fantastic.  I used a Trail tech Vapor speedometer and while it was a very nice unit, I could never get the accuracy of the tachometer where I wanted it.  The fabricated headlamp mounts also pointed the headlamp too high.  I did enjoy the comfort and handling of the bike, tremendously.

As a winter project for 2010, I decided to rebuild the headlamp mounts and lower the headlamp.  I also decided to change out the speedometer unit.  I fabricated a custom gauge set using FZ600 gauges and modified the headlamp mounts.  I modified the frame to accommodate the later style Seca II ('97/'98) rear tail plastics and then repainted the bikes tank and plastics to include a smaller decal and a center stripe.  I finished by repainting the wheels and adding rim tape.  This is the bike's current state:
