My Yamalink lowering link came today so after work I installed it, lowered the fork tubes about 9/16" or 14mm, then I went for a ride, about 5 miles of trails. What a difference the ride was much better, the bike handled better and it was only lowered about 1" or 25mm.
I would recommend this, it took less than an hour to do including the fork adjustment. The cost off ebay was $150 no shipping cost (in U.S.).
