Looking for info on my kart

Hi guys,
I don’t know anything about my kart other than it’s a Tony Extreme with a CR125. I don’t know what year it is but I think it’s late 90s? And I would love any information pertaining to this kart. As well as what brake system do I have? I’ll attach a few pictures. I’m really new to working on karts and don’t know the history or terminology for a lot of it. Any help is welcome.


Nice find on the homologation doc!

Extreme was homologated for 97-99. There were a few different versions with the “big triangles” one being the most popular. The Extreme was the first kart available with a 50mm axle that I recall.

The adjustable middle bar was pretty interesting but ultimately dropped in the Extremes successor, the Mitox.

Brake system is a TonyKart BS-1

I have some docs knocking around, I’ll see if I can find them.
