So at 40+k miles it's time to start planning on bearing replacement.
I have a 2003 BMW R1150RT with 144k miles on the original bearings so I'm a bit disappointed.
 
I did some research on bearings that I posted in the Zero 2013+ section that I've included below.....

Here's some bearing info...

Keep in mind that these are 6204-RS which are
(6) Single-Row Deep Groove Ball Bearing,
(2) Light Duty,
(04) 20mm (x 47mm x 14mm),
(RS) Single Sided Sealed,
(& I'm sure C3 & ABEC1).

Unfortunately the 47mm I.D. on the wheel bore limits this size bearing to (2) Light Duty design/constructed.

I'm going to procure new dust seals from the dealer however it looks like there are only 3 (2 for front & 1 for rear).
I assume that the wheel speed sensor contains an O-ring that acts as a seal?
If so, does anyone know it's dimensions?

To remove the bearings will this https://www.amazon.com/gp/product/B00NIPRNA4/ref=ox_sc_act_title_2?smid=ATVPDKIKX0DER&psc=1 work sufficiently?

If not I'll pick up a puller from Harbor Freight as it's reasonable priced with good reviews.

I would rather go with the first as it's less expensive & wont take up much space.


What bearing manufactures have you used?
I'll be looking at procurement from reputable sources from reputable manufacturers.
Planing on keeping the bike for awhile & hoping to get higher mileage from the next set so I'm not looking for bargains. 

I don't think ceramic is the way to go as the manufacturer (Zero) has limited selection to light duty and I'm not convinced they will last

I used one like that on my 14SR, it worked great, and also when I traded up to 2016 front wheel on it.
