How should a leather suit fit properly?

Small details make a big difference: The design of all 4SR moto suits is based on years of experience from racing circuits, numerous falls, and feedback we receive from professional racers. These valuable insights are applied to the final products for our customers. And since we aim to produce only top-functional suits, all our moto suits are identical. 4SR FACTORY RIDER = 4SR CUSTOMER.
