Performance Upgrades

I own a talaria XXX and want to slowly start upgrading it to be faster and have more torque. What combos are good? I was thinking a XLB-60 motor with a X-9000 controller and the TALARIA xXx BATTERY BY EBMX. Any recommendations? With this I’d need new brakes as I highly doubt the stock ones will stop me lol, what are good high quality brakes for this bike?
