Suspension - Rear Suspension Removal and Upgrade

[Rogue]

It says to remove the pump & motor with the shock.

How many miles on the suspension? I think ES owners are all looking for data points. TIA.

Great comment!!!

Talked to EPM, I do need to remove the preload hardware from the rear and ship to them.

Hyper Pro progressive springs to replace the factory have the following spring rates

Front: 9.5-14 N/mm, 54-80 lb/in
Rear: 106-160 N/mm, 605-914 lb/in

Good info!

Why are your replacing the front fork springs? I haven't heard too much bitching about those spring rates. How much do you weigh? How aggressively do you ride?

Does EPM give you a couple different options on the rear progressive spring rates?

Mostly because rider, pillion and top bag add up to 400 lb plus 40 lb tongue weight of trailer.

On rear there seem to be 2 options, both Hyper Pro progressive. 1 std and heavy duty.

Again, thanks for the info! I am assuming you went with the heavy duty rear spring?

 

[gbrmksmith]

Yes, I'm getting the heavy duty rear spring

I put AK-20's in the front of my bike with 1.10kg springs.
Dan at Traxxion says that's a good spring for the weight of the bike and for most riders.

Can't imagine that other places would vary too much from that

 

[gbrmksmith]

1.10 kg/mm would be 10.8 N/mm, so within the range for the HyperPro (9.5 - 14 N/mm)

Rear suspension, now with the preload adjustment assembly is out of the bike. You can get the entire unit out without removing the rear wheel and fender liner.

Interesting. That is against what has been conventional wisdom. Were you able to get them both out without removing the fender because you previously separated them?
