OUR ENGINEERS PUSHED THE BOUNDARIES
Optimized tube shapes, a more compact frame design, exotic hi-mod materials, and a dual upright, reinforced swingarm push strength and stiffness on this gravity defying cross country rocket ship.
The Mach 4 SL balances the diverse needs of the modern cross-country racer; it can be competitively raced on a short-track course one weekend or at an epic endurance race the next. It’s the right combination of comfort, control and speed that makes the Mach 4 SL such a pleasure to ride.
