Ssr xf250 Parts questions

[Poopy_mack]

I have an ssr xf250, 2015. I ride it as my commuter sometimes and send it off some 10-20 footers maybe bigger, I ride it pretty hard for a china bike. I throw some lil whips on it, ect. (I learned to race and jump on a 1998 kx250) I race district 36 (enduro) in California on the xf. Inevitably i will probably break wheel bearings and axles and blow out my shock. A few questions specifically,
1.) Is almost everything on the “drive train” and rear end comparable and compatible to the TU? Axles, rear shock, rear sprocket, swing arm?
2.) can anyone point me towards front suspension?
3.) I cant race until i get a good exhaust is there a semi legal performance exhaust somebody can point me towards i dont wanna fab too much i want a midpipe that looks like its meant for this bike.
4.) I cant seem to find another pair of nobby for it can somebody recommend some as well?

Some replys would be great thanks everyone i just joined the forum. Sorry for the poor grammar its been a long week idgaf lol
