I test-rode a '19 AT last week and loved pretty much everything EXCEPT the front end would dive during braking, certainly more than a GS I rode recently. It's true I weigh 250 and the suspension might not have been set up for me.


Any big guys want to comment?


Thanks,
pete

Hi Pete, I'm not a big guy, about 165lb in BD suit. But always re-spring/revalve a bike for my weight/use.

That said, the AT has a lot of travel, and can't be compared to a GS with paralever front end, which barely move.
With a re-spring for your weight (front and back) it would be fine.

This is what I ended up doing to my 2017 DCT. I'm just a bit heavier than you at 255. At first I redid the forks with springs from Cogent. This was a vast improvement up front, but it only made the deficient spring in the rear more noticeable. I had the preload on the shock cranked up to max, but I still couldn't get the sag proper for my weight. I was going to change out the rear spring also, but I was able to purchase a low mileage Touratech shock. The Touratech shock transformed the bike. I'm able to set the sag to the proper height, the ride is superior and the bike can finally carry a heavy load. While I have no experience with just a spring change on the shock, I've read that many people have been satisfied with it. So, you should be prepared to do at least change the springs front and rear. Call the folks at Cogent Dynamics, they will be able to help you further.

The bikes are not made for larger riders like us.

At a minimum, stiffer springs are needed. Best bet would be to take it to a good suspension shop and have it properly set-up.

First thing I do with any motorcycle I own is pay the price to have the suspension properly set-up.

My 2019 ATAS rides on an Ohlins Shock outback and stiffer springs up front.. World of difference

I seem to be hearing that the paralever doesn't have near the travel of the AT, which might explain why the AT is supposedly better off-road.


But I am not going to buy a new $20k bike and then immediately change the shocks!

I'm similar weight with an '18 ATAS and knew I'd be redoing the suspension before I bought mine.


Definitely needs springs at minimum and really a revalve because the stock valving isn't enough for the higher rate springs.


I installed an Ohlins shock with 105N/mm (10.7Kg/mm) spring and awaiting Ohlins fork cartridges with 7.5N/mm (.76Kg/mm) springs. I'd rather install myslef than have to take in or ship off and revalving the stock stuff can get pricey as well.



However, getting your suspension set up properly is the best money you can spend on your motorcycle.

I ride 50/50 and had a 2017 GSA. My biggest complaint with the GSA is the bike felt "numb" to me. I could never really tell or feel what the front-end was doing let alone the whole bike. With my AT and now my ATAS, I can feel when it's ready to break loose, you can feel what is happening with the front end. I ride my ATAS faster in the dirt than I did my GSA.

Offroad I never really had any problems with travel on the GSA.

Pete, I wouldn't give up yet. If you think the bike is for you talk to your dealer. I would make a low offer with the thought that the discount could be money applied to the suspension. If you've ever owned a bike with a properly sorted suspension you'll know that it is money well spent. I don't know where you live, but in New England where I live these bike sit on the showroom floor, sometimes for years. Discounts are readily available. Used is another option, again around here these bike depreciate a lot initially, then they hold their value pretty well. In my opinion the AT is worth the effort. I've owned a lot of bikes and this one is a keeper.

What would springs cost, assuming a shop does the work?

Well I don't want to.



1) Any info on the cost to have this done would be appreciated.
2) I'm going to rent one for a day. What modes should I put the suspension in, or how should I just the front fork?


Thanks,


pete

On a rental start off by maxing out the preload front and rear. The preload on the front is adjusted with the 19mm nuts on top of the forks, crank them clockwise until they seat. The shock by the preload knob on the left side of the bike. Assuming the compression and rebound are set to the factory settings, I would leave them alone to start with.

The price of the springs from Cogent Dynamics is 156.00 shipped for the front. I believe that the cost for the rear is the same 156.00. I can't tell you the cost to have them installed because I did it myself. As a guess, I wouldn't think the price would be to high as the installation is not that hard, a little more involved for the forks. There are youtube videos on spring installation that are very helpful. Depending on what you plan on using the bike for would depend on whether you would benefit from revalving. If your planning on hard core off road you would benefit from revalving, for the street and dirt roads I think the stock valving would be fine.

While I prefer linear (straight) rate like the Cogent springs, do they have the correct length for ATAS?



Hyperpro has progressive springs for ATAS, last I checked the front springs were $176 with fork oil from EPM Performance. Can also get kit with rear spring. That would be a start but the valving/damping won't be ideal with the spring rates being so much higher.


If not an ATAS, I'd go with the Cogent springs.
