“Great advantages are derived from small measures". It seems a philosophy maxim, but in reality it is simple common sense to those involved in karting. Those who know that drilling a hole in the chain guard can help disperse heat, or that mounting CNC machined hubs helps gain weight and efficiency. And for those who still do not know ... just continue reading this article

CHAIN GUARD WITH A HOLE

For safety reasons, all the chains used today, above all in the single-speed classes, fully cover the transmission. This is why the market has chain guards with side openings, which allow the passage of air, useful to dissipate the heat, especially in the summer. If, however, completely closed chain guards are used, a small trick may be to drill holes in the front area, allowing fresh air to enter the sprocket unit, chain and gear wheel.

CNC MACHINED HUB

Strolling around the tents of the teams involved in the most important international competitions, you may discover unexpected new accessories. It happened, for example, on the European OK and OKJ stage on the Naples International Circuit, where, under the Kart Republic tent, you could come across special hubs, completely machined from solid pieces and machined by CNC machines. The aluminium hub has the advantage of being lightened by being emptied. Furthermore, it dissipates more heat than a standard hub.
