What seat and how to install it in Birel S15 KZ

[Smokara1 (Hristo Iskiliev)]

Until now I had a tillet t11 ​​but it broke and now I have an original freeline seat.

Both of those seats should work just fine for that kart. But if you’ve never installed a seat before, doing it properly can be a daunting task. Its very critical that your seat is set up properly otherwise the kart will handle poorly.

I just picked up a brand new seat for my son’s kart, his previous seat was used with a million holes in it. I don’t want to mess up a nice new seat, and was hoping someone would have a good guide for seat mounting and positioning. Thanks

This thread should help out with guides and diagrams and such.

Here’s your reference chart.

I haven’t noticed any performance difference between the soft Tillet and soft Freeline. Dimension C is the critical dimension. The other ones tend to fall in place if you get C right. Hovering around 14cm has been a great starting point in my Compkart. Very similar to Birel.
