。
My father bought me a motorcycle.
Literal
Father [topic-は] me [to-に] motorcycle [object-を] bought [for me-てくれた].
買ってくれた — 買う (to buy) + the benefactive てくれる, framing the purchase as a favor received. バイク (motorcycle) is a katakana loanword from English 'bike' — note that in Japanese it specifically means motorcycle, not bicycle (which is 自転車).
