    I'm looking to get a pirelli scorpion front tire on my bike. I do a short commute on road and most of my riding is over loose rocks and dirt. Should I go for a soft or hard tire?

    I think Allballs Racing IS the Chinese junk he is talking about. There is a discussion over on Thumpertalk about them and some of the companies that use them under their brand name like MOOSE RAC,MSR, PARTS UNLIMITED:eek1.

    The SKF is 17x40mm bearing with double rubber seal. SKF explorer 6203 2RSJEM is what I have in hand. The explorers are okay - lasted two years on my BMW with stock grease. (it sees water, mud, etc). These ones, I'll take apart, wash all the grease out with solvent, and repack them with Maxima waterproof. Lets see how long they last.

    Maybe. Unfortunately, being in a pinch and unable to find quality bearing in the right size (I live near Timken, and they don't have one), I had to get Moose Racing set until I find a better one. Not paying Yami $60 for the Koyo that is shut at 5k miles.
    I found that SKF makes one, but special order in my area. I keep looking and will update once I find a good, EU or USA made product.

    With the SKF explorers, the same part number can be made in Germany or Argentina or...

    Are you replacing the axle seals as well? If so, where are you getting them? I always wonder when people talk about buying bearings at auto parts stores or bearing houses where they're getting the replacement seals from, or if they are even replacing them.

    That SKF is available from Amazon.

    Are saying you want to avoid the SKF? I understand about wanting to avoid the no-name chinese bearings but a brand like SKF or Timken, etc... I think the country of origin means a little less in terms of quality.

    If they are good, I keep the seals. If not, most autoparts stores sell seals as well.

    I am saying SKF over anything else if available. Just my personal experience.

    Timken is even better, IMHO but hard to find for our applications.

    Update: I spent an interesting 30 minutes on the phone with a SKF tech guy who spoke in terms I did not understand (regarding forces, et cetera). The 62/22 (22x50x14mm) is available, but not in Explorer quality. part numbers are 6222-2rs1 or 62222rsj (rs1 is an unknown seal, rsj is a rubber seal pressed in steel cage). Those are industrial bearings, and he ran some numbers. At 200RPM of wheel spin and radial force of 450 lbs, with some axial force, that bearing is rated at 17000 hrs of use before the bearing grooves the cage, with stock lube rated at 40000 hrs. I have not tried or tested this bearing myself.
    The 60/22 (22x44x12mm) is available by special order only and the part number is BB1-4724 . Minimum order and lead times will apply. So I was told.

    I never thought to use my WR as a boat either, but apparently according to this video it can be done

    I found these
    http://pivotworks.com/ProductInfo.aspx?item_id=1558 Seem inexpensive I sent an email to see where they get their bearings, but no reply yet. They do say they are ABEC3 and come with a lifetime replacement guarantee.

    I have the Richochet and my friend is running the Flatland one.

    When I look at the two side by side the Flatland has better protection especially around the water pump. I have made the decision to replace my Richochet with either the Flatland or Moose Racing plastic skid plate.

    Just beware that when you bolt on one of the Al skid plates you are going to wonder what is wrong with your motor the first time you start it up. The Al resonates pretty well. Some of the guys will coat the bottom of the skid plate with spray on bed liner from a can. Based on my experience with my KTM that seems to work pretty well.
