Stop valve stem ripping out


Racerex

Ripping your valve stem out is a terrible way to end your ride. Try this next tire change: when tightening the rim lock, (especially on a fresh new tire) make sure to re-tighten it after a bit of riding. The rim lock will "bite" into the tire slightly after a few stops and starts. Tightening about 80-90% followed by re-tightening will increase the "bite", more than one extreme torque job. Rims can be deformed quite badly from over tightening rim locks.

If very low psi/run-flat ability is desired, using two rim locks spaced 180 degrees (opposite each other) on the rim is the best option.

For extreme cases like competition hill climbs and sand drags, some racers will drill six or more holes through the rim flange and screw the tire bead to the flange with sheet metal screws. Usually this is only required with lots of HP and traction. Roost with confidence! :thumbsup:

      Rad Manufacturing is now one of our premier manufacturers and we thing you will be impressed especially when purchasing something as important as wheels for your best friend the KTM 950/990 Adventure or 950 Super Enduro.
      We aren't talking about just any bike we are talking about the bike that will go to the end of the world with you if you ask that from it.
      We want to help you make the legs on your adventure the strongest and most farkled set of legs you can get. RAD will help us with that.
      From mild to wild they have it all. Start off with their Billet Cush Drive hub and grace that with heavy duty stainless steel spokes.
      If you are up to it and we think you are you may want to oversize those spokes and add a +1 to the gauge which will save you from the wobbles.
      Finish that off with either a strong CACR Rim or our favorite rim of choice Sun Rim.
      Now that we have racked your brain with all of these choices we have added anodizing and powder-coating options to personalize it even further.
      From stock sized 4.25x18 rims to track ready 5.00x17 you have everything you need to build that custom rear wheel.
