Dennis Kirk has the Moose bearings. I just installed some in my 250. It was very easy. https://www.denniskirk.com/moose/ste...prd/505750.sku
Here's a better video. http://advrider.com/forums/showthread.php?t=363572
In the video, the guys reuse the old race to seat the new lower bearing. Instead, I used a large nut with a 1 1/4 inside diameter that slide over the stem to seat the new lower bearing. It was my first time doing a set of steering bearings and it was a piece of cake.
