  • Completely WATERPROOF

  • CNC Precision Machined

  • Choose Black Anodized or Chrome

  • 2 numbered keys included

  • MOST ARE READY TO USE OUT OF THE BOX - only 2 models require using your existing oil stick - the ONLY tool you need to install is needle-nosed pliers

  • Low cost and cost effective


  • Protect your bike engine and your investment

  • Eliminate the threat of someone messing with you by sabotaging your oil

  • What is the cost to rebuild an engine damaged by foreign objects entering through an unprotected oil cap? Stock engine or after-market parts? $6,000. and up is the figure we have, but it depends upon how much damage.
