Rebound setting on new bike 2018 model

I’m a heavy guy...5’9 275+ lbs. I asked the dealer to put the spring on 5 and stiffen the rebound for my weight. They didn’t do the rebound. My buddy took a picture of me on the bike and I think I squat the bike too much. I think the bike dropped 3 inches or so with me on it which is probably normal. Now with the rebound turned up all the way the bike drops like 3/4 inch! So I can dial back now out on a road test and get it where it needs to be.

OK a couple things;

- the spring preload is the only thing that affects sag; while conventional thoughts are sag should be around 33%, I think that due to the limited travel of the heavy KLR I'd aim for the low side. On a Gen2 with 7.3" of rear travel, 30% = 2.25" and 33% is 2.4. 3" is 41% and is too much IMO.

- The KLR has only one damping adjustment that does both compression and rebound damping. I don't have much experience with the settings for the 2014.5+ bikes but start mid way and play with it from there. Lots of good reading on determining optimal damping settings and since the KLR's adjustment is so rudementary it isn't rocket science.

good luck,
Dave

Agreed!

I was looking around at cost for Cogent upgrade. Cogent seems to be recommended most often here.
$650-700 for rear shock and spring. Is that cost about right?
Other less expensive options?

Hi Dan,

Cogent offers several shocks and option combinations for a variety of prices. There shocks are the Adventure - $ 489, the Moab - $ 639 and the Ultimate Pro-series which (with all the goodies) tips the scale at $1,375.00

The Adventure is 10x the shock the stocker is and is all that 95% of KLR Owners need. As I've said, I've had all three. Other options are Progressives 465 which runs around $661 currently...... periodically I've seen them around $500 on sale in the past. They have the damping adjuster (like the Moab) but I believe the Adventure is a better shock and Cogent's customer service is second to none, hence my recommendation. There are other shocks out there too; Elka, Ricor, Touratech......there are lots of articles on each though it's much harder to find any real comparisons - I have some


Cheers,
Dave

My bike doesn’t seem to sag at all or much with rebound turned all the way up. It rides like a brick! I need to go down to 1/2 and play around. I did call cogent for some suspension info. Super nice people. They will be getting my business someday

Iím sorry to say this but rebound adjustment has nothing to do with how much the bike sags when you set on it. Rebound is how quickly or slowly it comes back up after the suspension has been compressed. The spring preload controls how much sag you get when you set on it.

I understand what your saying but that “ dampening” adjustment office is allowing or denying the flow of fluid internally inside the shock. When it’s set on soft I can flat foot 1 foot. When it’s on full hard I’m on balls of my feet on both feet. Eventually it will sink more but the sag is less when the setting is on hard

My terminology was incorrect in previous posts here. Dampening was the correct word

actually, you're wrong that you were wrong; Damping is the correct term!
