Developed in the factory for the course – the fourstroke FS01 sets the standard for lightweight, race-standard full suspension bikes. With a frame weight of 2000 grams ( including shock system ), optimized APS suspension system and perfectly coordinated components, the FS01 offers the ultimate in ride performance.
Maximum propulsion and traction, precise steering characteristics and directional stability combined with a compelling aaesthetic, that’s the fourstroke FS01.

Suspension system that ensures comfort, unsurpassed traction and efficient power transmission in any biking situation.
With a neat combination of different carbon fibers and their alignment, and by applying stepped tube profiles, we achieve increased vertical compliance while maintaining high levels of lateral and torsional stiffness.
Tube junctions perfectly tailored to the distribution of forces. Cleverly selected skeletal reinforcement elements at the nodal points and the spread of the top tube distribute the impacting forces perfectly.
Direct assembly of the brake cylinder at the frame without adapter.
Used for the best possible adjustment of the sag, can be easily checked when getting on and adjusted where necessary.
