    The seller went above and beyond. Called and asked if I had the proper passenger seat to match this seat or it would not fit on my bike. Explained I did have the proper passenger seat. They said great, it's going out today! Excellent quality. Arrived in pristine condition. This is one comfortable good-looking seat. Amazing value for the money. Very well packaged. Fast shipping!

  • YZ250 2012 no issues

    Product is as described. Ran the break-in process and had the bike out at the track. No issues. Like always be sure to check your ring gap. I had to file mine meet the clearance for myYZ250. Of course it really comes down to cylinder wear but either way good to check!
