Rear shock

[chadz]

Does the sx and sm 125 share the same rear shock absorber as the rt125?. If not is the rt adjustable
Becuase i have been looking at my shock and seem you can by the huge nut...

If the "huge not" is on the bottom of the spring that you are talking about, that is used to set the pre-load on the spring. This is used to set the "sag". It is the single most understood concept of suspension tuning. This will accomodate, to a varing degree, differnent rider weights. Tightening (compressing the spring) will increase when the spring first starts to move. It will not change the spring rate - in other words it will not affect how the shock "bottoms out". The 125's are to simple (read cheap) to offer compression or rebound dampening.

The RT shock is about 3/4" shorter than the SM & SX.
