Ergal RK KZ Crown – High Resistance & Ultra Light (Axis 50mm)

The crown RK in Ergal for KZ is the outcome of the transmission research for competition karting. Subjected to phenomenal couples during crossovers, it was developed with a special manufacture to offer a record lightness (only 285g) without ever sacrificing the strength of the teeth.

Characteristics Performance techniques:

• Material: Ergal 7075 high density (aeronautical aluminum alloy).

• Plum weight: 285g (about 25% lighter than a standard crown), reducing the inertia of the rear shaft for fulgurating reels.

• Secure Design: Includes screw without integrated head (point) to block the keyboard and avoid any movement or slippage on the 50mm axis.

• Reporting range: Available from 20 to 30 teeth to adapt to all types of circuits (from the most sinuous to the fastest).

• Dimensions: Designed specifically for trees of diameter 50mm.

• Packaging: Delivered in compact box of 14.5 x 13.5 x 4.5 cm.

The Magickart Commitment: We know that transmission is the sensitive point in KZ. Magickart guarantees the lowest price in France and Italy on the entire range of RK Racing crowns!

The Council of Michel (Magickart): Crown RK Ergal KZ

"In KZ, the crown impacts every speed shift. My expert advice: Never neglect the clamping of the small headless screw provided. It ensures that your crown stays perfectly aligned with the motor sprocket, even under the constraints of the 125cc engine with gearbox.

A little pro secret: with such a light crown in Ergal, alignment is your best ally. If your chain is wrong, you're going to 'mill' aluminum prematurely. Use a Laser lineer and make sure your chain has a 10mm game. A well-adjusted RK crown is the guarantee of passing all the power to the ground without unnecessary friction. And remember, at Magickart, we are the cheapest in Europe so you can have all the teeth in stock in your toolbox!"
