Suspension Set Up

[dandywarhol]

I'm in the same boat.

Around 120 kg or 18 stones ish with my gear on.

This means around 40 procent dynamic sag on my 09 TDM 900 with one ring left I the front and as hard as possible in the rear.

I've been around asking and have found two solutions so far.


Hyperpro progressive springs made for my weight


Ohlins linear springs.

Fork springs are only made in 80 NMR and he could not tell me the rate on the original springs.

Rear spring in 180 Nm ( original should be 120 Nm ) but the dealer could not tell me if it would fit on the original shock. If length on spring is diff the rate will not be correct.


Both sets are around 500 US, and if I could be sure to get it right, I've would go for the linear springs, but there is a lot of question marks.


Anybody knows what the rate on original fork springs are, and how to convert between Nm and Kg?



Have anybody tried Hyperpro progressive springs front and rear ? I'm not sure what to expect because some people are happy with Hyperpro, and others say that it is shite.

Would think that linear springs would give almost same ride as now, just a bit harder ?

Nm is torque and kg is a force so there's no conversion.

 

Sounds like you're talking about 0.8 kg/mm (0.8kg moves the spring 1mm) - spring rates vary on different model year 900s, I think it tells you somewhere in here http://www.jbx9.t15.org/index.php?page=SUSP
