Yea just get a ninja 250 or something like that to learn on for a year wont loose much money, rego is like 400 bucks for a 250 and insurance just get third party which is probably like $150.
Gear wise you'll need helmet $300-500 (mine was like 480, could spend upto 1k if you want, depends what fits and feels good), kevlar jeans like $200, jacket is $4-500, gloves $50-130 and I'd recommend getting some boots when you can afford them say $200-250 for normal ones. TBH gear really depends on what you want to spend, but personally i'd set aside 1-1.5k for gear.
