I had two red ones - a '94 and a '99. Have since had 1150s and 1200s but looking at yours makes me want another 1100. I liked only having five gears! And I swear my '94 was the most 'grunty' of all of them. Looks like yours is a '94 with the plastic tank.
A nice bike!
All it needs is a yellow seat, BMW grips and to lose those bars.
