"The choice of hub length is your first adjustment lever. My expert advice: The 92 mm hub is the standard mount at Tony Kart. It offers the 'grip' needed for European tracks. If you feel that your kart 'saute' too much in turn, it is often the sign that you have to pass on this model of magnesium rather than aluminum.
The indispensables with your hub OTK :
Magnesium MXC or MXJ wheels: For a perfect combo in terms of tyre temperature management.
Shaft clavets 8 mm: Check the condition of your locks to avoid any mechanical play.
Copper fat: Apply a thin layer to the 50 mm shaft before mounting to facilitate future rear-track settings.
A little pro secret: Magnesium is a noble material but sensitive to oxidation. Always clean them after a race in the rain to keep this golden 'Factory' look. At Magickart, we swear only by the origin OTK for the accuracy of the rear gear!"
Cleaning: The 50 mm shaft shall be free from rust and burrs.
Positioning: Drag the hub and align the keyboard.
Lock: Use a dynamometer key if possible. Magnesium must not be tightened 'to death' to avoid cracking the collar.
Setting: Remember, the more you get the hub back to the chassis, the more you increase the rear grip. The more you spread it, the more you free the train.

Validated Performance: This is the hub used by the largest international teams.
Fast Delivery: A twisted room in a fight? We ship immediately to get you back on track.
