TonyKart / OTK Castors

The Senzo castor kits for TonyKart / OTK karts including the Komsic, Alonso (FA) and Exprit. 

Not only does the kit give you the ability to add castor, it gives added advantage to remove front end chassis castor, thereby reducing front end corner entry grip!

You'll be prepared for any condition with this kit from a lovely summers day to torrential rain.


  • DOT 1
    • This gives you the least possible amount of castor for the TonyKart / OTK chassis. The higher the number goes the MORE castor you gain.
  • DOT 2
    • For more castor than the DOT 1 castor pill where you require more castor and improved turn in and mid corner front end grip
  • Blank Castors
    • The gives you half castor in between the standard zeo / full castor. Very good in both cold and warm conditions. For when you require more inside rear wheel life and more release from corner grip.
  • DOT 4
    • For more castor than the standard OTK full castor kit. Great In wet conditions where you may require more front mid corner grip.
  • DOT 5
    • For even more castor then the blank and DOT 4 castors. Great for really wet conditions where you require the most turn in and mid corner front end grip possible.
  • Castor/rear bumper wrench
    • Tool for adjusting both the Senzo castors on a TonyKart / OTK chassis and also to tighten the bush on a rear bumper bolt kit.
  • Magnetic covers
    • The most attractive magnetic castor covers on the market. Use these to cover the top castor adjuster from prying eyes, two are included as part of a set. The extra strong magnets ensure it doesn't come off during racing.
