Most bikers are aware of the importance of keeping an engine in good condition, many seek to improve performance, modify its operation, optimize the power supply. Most motorcyclists also understand the importance of tires and take care of their hold and unfortunately a lesser part is interested and realizes the importance of suspensions.
The cycle part of a two-wheeler is composed as follows:
- the frame (the frame of the motorcycle)
- the swing arm
- the front suspension (fork)
- the rear suspension (with one or two shock absorbers)
The first two elements are fixed, do not need to be maintained regularly. On the other hand, the suspensions are mobile, work, wear out, deteriorate with time and mileage. They require regular maintenance.
Their primary function is to absorb the shocks linked to irregularities in the road, to ensure the grip of the tires and the stability of the vehicle.
This adjustment is ideal if the motorcycle is going up and down symmetrically between the front and the rear.
Two things make up the suspension on your 50 SUZUKI motorcycle RMX In 50:
- the spring which generates the movements
- the hydraulics which control it.
On a fork, as on a shock absorber one can find 3 following settings:
- pre-loaded
- compression
- relaxation
The preload relates to the spring. The spring will be more or less compressed in order to adjust its hardness; in general the setting is done byar a nut and locknut system. Attention, on many models, there is not automatically the possibility of adjusting a shock absorber, they are sometimes without adjusting nut.
A spring that is too compressed will be very hard, which will not prevent it from properly fulfilling its role as a shock absorber. Conversely, a spring that is insufficiently compressed and therefore too soft, will very quickly come to a stop.
If the spring is old and does not seem to be sufficiently compressed and it is not adjustable, we recommend that you replace it par a new model. Indeed, on small cylinders, they are most of the time "basic" and non-adjustable shock absorbers.
The compression settings are currently those recommended spar fault par the constructor. It's up to you to see if you want to strengthen everything by tightening the compression adjustment screws, or on the contrary soften everything by loosening these same screws. Let's refine everything now by exerting pressure on the tank as indicated above:
- If the front goes down faster than the rear, it means that the rear is too compressed or that the front is not compressed enough. In these cases, release the rear by loosening the compression adjustment screw, or firm the front by tightening its adjustment screw.
- Conversely, if the rear goes down faster than the front, this means that the front is too compressed or that the rear is not compressed enough.
As with the preload adjustment, if you do not have compression adjustment screws, then you will not be able to intervene on it, it will be necessary to consider replacing the rear shock absorber of your 50 SUZUKI motorcycle RMX 50.
A flexible suspension adjustment seems to make the bike more forgiving, less lively, and a little less tricky, especially on bumpy surfaces, at good speed.
The low preload where the motorcycle will crash during long presses (braking and acceleration) and with a rather open hydraulic (relaxation and compression) which will allow better absorption of shocks .
These aspects can be more harmful on roads, at high speed, and especially on circuits.
The rebound is the hydraulic value which makes it possible to regulate the speed of rise of the shock absorber.
The adjustment principle is the same as that for preload or compression. This is a screw that controls a valve. The more the screw is tightened, the more the suspension will settle on repeated small shocks that do not have time to rise. Conversely, the more the screw is loosened, the more the suspension will tend to rise sharply.
If your shocks are too soft and come into a mechanical stop, the motorcycle may sway at high speed. The spring preload should be hardened. (increase the preload). Otherwise it is that the spring is too flexible par in relation to your weight and the stresses imposed on it, and that it must be replaced.
