Suspension
« on: July 24, 2017, 11:37:45 »
Hi,

In other forums there is evidence the front forks are not up to their task, anodizing is too soft.

Also we all know rear is undersprung for "full load" bad roads ride.

Kiwi has changed his rear, anyone done modifications to the front?

I been riding alone with moderate load so I am still fine, lots of pre-load to add and just some small modifications of other adjustments have been needed...

I'm still trying to figure out the front suspension issues outlined in the suspension thread on AdvRider.com. I think the issue comes from extended use of the bike on rough terrain.

Given the AT is designed and marketed as an around the world adventure bike this has to be a bit of a worry.

My view is the suspension seems fine for one up riding with gear on the AT. I knew soon after buying the AT that I would more than likely need to increase the rear spring rate as the load I need to carry with me, my wife and gear is 220 kgs, which as we all know exceeds the OEM recommendations. I could have gone with just a heavier spring rate but I also wanted more control over pre-load, rebound and compression adjustments. The Ohlins I fitted (plus a number of other brands) gives me a wider range of adjustment settings. So my need to replace the rear was not because the OEM rear was a bad shock, it was simply the shock performance criteria was not adequate for what I am asking of the bike.

This is a different issue to front fork wear.

Following my ride back from the shock specialist works hop to home (a 400 km trip) I was not going to change my front suspension. Now I am keeping an eye of the experiences of others.  I'll wait for a bit and see how this pans out.

...


Are you tempted to pull your forks apart to check the internal wear?

@ David, have you considered to give the Africa Twin the full job in one go? In other words, also add progressive front springs with spacers and thicker fork oil as well?
You have experienced first hand on the Transalp what a big difference it makes!

Yes, but not progressives. I do not like progressive springs. I'm going to wait as the front appear to be good still.

No, not yet as mine are smooths as "silk" after 22k  ;D

But I recommend if anyone is setting up front to check the tubes very well...

Yes rear show its limitations on two and luggages, bad roads or off roads tracks trips ... I' m looking first for an economical evolution, perhaps add hyperpro spring on the rear, with perhaps +20mm, perhaps a solution to have some more preload ... Wait and see

Antonia is about the same size as your wife, but I am a lot bigger than you so you can imagine then the limitations I was riding under. The new rear suspension gives me lots of adjustable scope for pre-load, rebound and compression, but I need it. I would think for you starting with a heavier spring is a good option.
