The 1st Guzzi we got was an `81 CX100 (LM2).  It's still my favorite bike !   With the Corbin seat & it's built-in dash clock, it really can be a 1 or 2 up bike.  It has a 5 gal. tank & we can go @ least 200 miles between fillups.  We get 50-60 mpg with it.  Two times I've had to put 89 octane in it & it runs just fine, though mileage drops to 40.  One the the bonus features of this bike is that you can mount normal handlebars vs. it's clipons.  I added euro. touring bars.  For when needed, I've already bought nigasil/piston/barrels for the motor so this bike should be running the rest of my life !!   

     A couple years ago I got an `87 LM4.  This bike is definitely made for 1 person only.  It's my fastest bike & needed little to make it better.  Just a Corbin seat, rear rack, & REAL crash bars.  If I have to haul ass, it's my best bike.  It'll cruise @ 80-90 all day without really working.  It has a 5.8 gal. tank & I get 40-45 mpg with it which means I can go @ least 220 miles on a tank.  Because of it's added power, it does need rear tires more often, but runs on 120/ or 130/  tires which aren't as expensive as the fatter tires.
