Honda PCX 150 Custom Rear Shock Spring

[Meteorpx]

Hello all

I have a Honda PCX 150 with a stock rear twin shocks with advertised travel of 9.34cm.

The rear shock is really stiff, the actual max travel I get is around 1.50 cm with me riding the bike solo (I weight around 75kg).

I started wondering why they put such a stiff spring on this bike (I suppose that's the culprit), limiting the travel like that making it impossible to absorb properly even minor road imperfections.

My idea is to custom order 2 soft springs and swap the springs in the stock shock (the shock is serviceable like that), with that some concerns come to mind:

- This would increase the movement of the swing arm on the bike, would that be ok or I would be hitting something on the frame or other part? What I should verify first?

- How I would go about determining the spring rate in a way that I have a plush mounted rear shock?

- Is this idea valid or I'm missing something here?

- What are your general ideas on this?

Thanks!

Can anyone help?

The rear spring is actually pretty soft as carrying a passenger actually makes the rear drop down considerably. I really wouldn't mess with the spring rates as the dampers won't match and it'll just be going down a never ending hole of spring too soft, dampers too hard etc.

If you're looking to change rear shocks, just buy a complete kit with a reservoir and rebound plus compression adjustment. That'll really improve the ride as you can make it so the compression is really and fast with a slower rebound will give you that nice cushy feeling.

Look at YSS or Ohlins(very expensive but best in business)
