2016/2017 Apollo 250RX Help

[Ivang217]

Hey guys!
I'm pretty new to the whole dirt bike riding, slowly wanting to get into street bikes, so I started with a dirt bike and I choice the Apollo 250rx will post some pictures below. I happen to be riding it in the neighborhood when I hit a very nice slick spot and the bike just went crashing down and it broke a brake lever and it's pissing me off, I couldn't find anything on what works with model bike.
And tips and suggestions on maintaining this bike for a long time, I wanna keep
Her alive as long as possible.
Thank you!!!
