Which 2t 125ccm cross should I buy?(2000€)

Hello dear motorcycle community I have to get a 2-stroke motorcross next year in spring (without registration) Now my question is what can you recommend me for a 125 2t (reason would be quite cool) I am about 190cm tall and about 90kg heavy. I like the Yamaha yz 125 quite well. I would have about 2000 Euro, you get for the money something clever ? The whole pack should be good / good chassis / etc… Had to before only 4t but wants to me the whole electronics and valves nich t do more. Change to nh 125 2t
