The shock absorbers seat lift spare part to the original for scooter Yamaha XP T-Max 500/530/560 allows to restore the correct opening and closing of the saddle mechanism. The continuous use of the saddle opening leads in the long run to the wear of the mechanisms which may not guarantee correct opening and closing. Among these mechanisms, if not more efficient, it is advisable to replace the piston (gas spring) seat post.
NOTE: use the original pawl/uniball, order 2 pieces to make a complete left and right kit
