I wanted to give a follow up on the performance of my new Brigestone 401f front tire. I will post a link for referance. Order one from thumpertalk. I believe they have access to them. http://www.rockymountainatv.com/Product_Details.atv?pid=00105410 I have 10 hours on the tire as I write. I have been is some terrible conditions with it. Sand was day one, the other day was in an old mining area. Lots of hardpack and small rocks. This tire is special due to its size. It is slightly taller and wider than normal. It is noticable once its mounted on the bike. This is the best front tire I have ever used.Nothing else comes close. It grips like crazy and shows no wear. I prefer it to the 756rr. Thats how good it is. I would continue, but there is not much else to add. I believe Brigestone could offer a money back guarantee on this tire and not get one returned.
