Better still, our engineers built in real compliance, real durability, and the handling and features that really win races.

                                                                                                                                      F-Si attacks the steepest climbs and nastiest descents of modern World Cup XC courses. The Ai offset drivetrain and OutFront steering geometry deliver an uncanny mix of stability, agility and traction.

Its one-of-a-kind design lets it float through the chop and steer through the chunder like nothing else.
