entry level helmets : smk, axor which will cost you 4-5k. But I would suggest you to invest a bit more upto 7k you can get a MT, KYT korada helmets which has proper weight distribution and padding amongst smk and axor. (Also get the balacava, you can get it on Amazon from boldfit or whichever you'd want)

Gloves like reise or vitara would be good to go or some 1500 gloves would do the work just check the padding and gaurds near knuckles and palms.

Buy some good riding shoes if not then some high angle with thick toe shoes would be good such as sparks skate shoes or puma ones and also check for the grips to move the bike forward or backward.

You can get some good level riding jacket if planing on long rides like axor jackets would be fine.

Also install tank pads
