What you should really be the company Puky say other than that the GoKart also has a flawless workmanship. We were initially in a large toy chain and thus have the possible answer noted several brands (including Kettler) side by side and test. And since a lot of choice very quickly on the go-kart F550. The others were partially unstable, wobbled, quitschten like crazy (or not holding). Not exactly inspire confidence. I know now some say "but it is also clear demonstration models". Yes Yes. But that was also a demonstration Puky, wiggling there squealed nothing. Highly stable, alone already by the double, supporting pipes on the steering column. When you consider how often such a vehicle the curb up and down again drives is important a stable, solid base. And the look is awesome in my eyes. The GoKart you're the King. The powder coating also resists many a hard blow. My absolute buy recommendation. Other manufacturers are also not much cheaper. But here, the purchase price is justified
