This is a standard seat that has had the foam cut down to form a low seat. Approximately 1.5 inches foam left. I used the seat for green laning and commuting to work and found it comfortable for that, you would not want to sit on this seat for hours at a time (although I did 1200miles on it in 10 days following the river Ebro). Lowers the seat height about 4 so enable a short ass to take a dab in the lanes. I had it professionally recovered. In good condition. Will fit any blue TTR 250. £40 plus p&p.
