Many bikes are nowadays
advertised with the fact that it has a monocross suspension. A major
merit of this Monocross suspension is that, compared to the conventional
dual shock absorber type, it can be positioned close to the machine’s
center of gravity to improve the concentration of mass. Also, it enables
greater freedom of positioning of the shock absorber unit and makes it
possible to get greater wheel travel than the actual stroke of the shock
absorber unit. With a p14mm rod and a q 62mm spring and an optimized
design for the valve that created the damping force, the rear suspension
of the FZ16 achieves the necessary maximum load capacity.
The spring is a two-stage type with a
different coil pitch in the upper and lower halves. The tighter coiled
section contributes to a smoother ride, while the section with fewer
coils supports load at the time of the larger stroke to prevent
bottoming. By the way, of all the motorcycle makers, Yamaha has the
longest history of Monocross suspension development. It way back in 1973
that Yamaha mounted a 250cc motocross competition machine, YZM2SO, with
a Monocross suspension and won the world championship. After that, the
Monocross suspension became a standard feature on many production
models. Today, it continues to evolve as the world standard on sports
bikes by all makers.
