Frequently asked questions
Which Zelos variant suits which class?
The Zelos K for Junior and Senior in the gearless classes (OK, Rotax MAX, X30, ROK and more), the Zelos D exclusively for the Rotax DD2, the Zelos Z for gearbox engines and the Zelos G for endurance races with Honda 4-stroke engines (GX200, GX270, GX390 and sport versions), for example in the GTC.
How can the chassis of the Zelos be adjusted?
The steering is a Vario steering with Sniper Adjusters, plus a front stabiliser (Stabi 1+) and HRP VARIO NG pedals with footrest. You adjust camber and caster via the Sniper Adjusters.
Which engines and tyres are used in the Zelos?
Both depend on the regulations of the respective series. For engines we work with external tuners. You can buy the range of Rotax engines from us, as we are an official Rotax service partner.
What is the difference between the Zelos and the earlier FIA5?
The Zelos is the further development of the FIA5.
Do I have to bleed the brake of the Zelos before the first use?
No. The chassis is delivered pre-assembled and the brake is already bled.
Which seat do I get if I do not specify one when ordering?
For Zelos K, Z and D the Jecko White Soft C7 is included then. Available are Jecko Silver, White Soft, K-Model White Soft and K-Model Silver in various sizes. You state your choice in the comment field when ordering in the shop.
Where can I buy a Zelos?
We usually sell the karts through dealers who can offer the best service. You find the dealer near you via the "Find a dealer" button. The Kart24 shop is the fallback and the reference for spare parts.
