Is participating in the sale of motorcycles to customers via the bank in installments, with added interest, considered participation in something unlawful?

If the bank lends the customer the price of the motorcycle with interest, this is an usurious loan. Your submission of the file to the bank is considered cooperation in this usurious loan, which is impermissible, as Allah Almighty says: "And do not cooperate in sin and aggression. And fear Allah; indeed, Allah is severe in penalty." It is advised to present the matter in detail to scholars specialized in the questioner's country.
