Agreed. I checked my engine mounts and found some were WAY over torqued from the factory...and some had gotten loose.
I've started taking every Motorcycle I buy and loosening all the mounts (while supporting the motor) and tightening to spec in proper order.
I'm on my 4th Motorcycle doing this and it has helped with vibration every time.

Re: 1250 Suspension Mods for Touring?

Ive banged and bounced around on backroads long enough on my 08 1250,Ive gold valved and re-sprung the forks,nice but the shock really hurts my back over sharp bumps. There's a sale going on full boat Ohlins with remote preload and remote reservoir. 1100.00
I may do that. Theres also the YSS on ebay for 360.00 delivered from UK. I hate to spend even 360.00 if it isnt a lot better then stock. Sumpins gonna happen pretty quick here though. Most aftermarket shocks it looks like reaching the pre-load rings is just about un-doable. Any other ideas?

See #136 above. Strongly recommend the Cogent rear suspension unit. Those folks are very easy to deal with; if it helps your decision any, they use Ohlins springs. Preload is very easy to adjust with the bike on the centerstand.

Thanks for the response! How would you rate the "plush" factor on the Cogent? I like to zing around on backroads some but also do some long rides on the 1250. My lower back wont take the kicking of the oem shock.

Re: 1250 Suspension Mods for Touring?

It's probably best to keep suspension settings close to recommended. Here is a good how-to on that:
[instructions from Metrick Metal]
The rear suspension travel for the Bandit is 5.4 inches and most suspension manufacturers recommend using between 25 and 30 percent of the total suspension travel for rider sag on a street bike.

So to get an idea of where your at you need to first measure from the center of the axle to a referrance point directly above the axle with the bike on the center stand, so the shock is fully extended, then sit on the bike and have some measure from the center of the axle to the same referance point, and the differance between the two is your rider sag.

Use the dimensions below as a guide to see where your at, and remember increasing the preload does not increase the rate of the spring, it only increases the amount of force required to get the suspension moving.

25% of 5.4" = 1.35"
30% of 5.4" = 1.62"

What I made up for the Bandit so that I can check the amount of rider sag by myself is this plug that slips into the left end of the axle, and the slot allows me to hook the end of my tape measure into it which place the end of the tape measure directly in the center of the rear axle.

I then tape a piece of masking tape to the corner edge of the tailpiece directly above the rear axle and I put a felt pen line on it, then i have a small square mirror that I hang from the he back of my stool that I place next to the bike, than its easy for me to read the dimension of the tape measure against the felt pen line to see the amount of sag I have.
[end of instructions]
I haven't strayed too far from the settings Cogent provided for my calculated touring weight. If you're riding around lightly loaded, you can easily back off the preload at both ends: up front you just turn the screws on top of the forks out; in back the included spanner from Cogent works very well. It works even better if you remove the three socket head bolts for the left footpeg.
With my setup I just leave shock valving in one place, going with Dale's and Cogent's advice. It rides better loaded, in any event - could be called "plush" compared to stock. Or even better "controlled, unruffled".

Re: 1250 Suspension Mods for Touring?

Wow. I finally got the Cogent shock installed on my 08 1250,and the forks done with gold Valves and 1.1 springs. I cannot believe the abuse my lower back and shoulders took for 13,000 miles with the stock "suspension" I tend to ride rougher backroads and enjoy spinning it up around corners. The bike takes sharp bumps Much Better,and turns in to corners like a whole different bike. I had Joe the suspension guru set the gold valves in the forks to the softer end of the settings. Seems good kinda feels like 1 step stiffer springs might be good. I will add 20cc of oil per leg and see what that does.
I weigh 190 usually ride solo. Still need to finalize sag settings,but man o man that stock suspension is by far the weakest point on this bike. So much better and less painful. I think the 1250 is a keeper. With 23,000 miles on it its barely broken in.

Since you like to corner, raise the rear 1 to 1-1/4". Makes the bike feel like its 100#'s lighter. No stability issues at all - the Bandit has very conservative steering geometry.

Re: 1250 Suspension Mods for Touring?

Does anyone know the reason why Cogent springs from holeshot are 1.1 kg/mm irrespective of different rider weights?

Just having the Cogent on the bike raises the rear some,just like the people at Cogent said it would.
If I raised it 1" or 1 and 1/4 I would be looking at re-doing the centerstand and kickstand.

They have 2 springs,I think if your over 220 or so you get the heavier spring. With easily adjustable pre load it seems to work fine on mine.

I have the Cogent shock and Holeshot links that I run in the lowered position. With them in the high position it's crazy tall. I'd like some stock links to bring the back end up a bit.

And the issue is..........? My side stand has ~1" block of black delrin screwed to it. Doesn't look too cool, but that's not why I ride. Just put a 1/2" thick piece of wood under the centerstand, problem solved. Don't overthink things.

It steers and works great as is. The only problem now Is I need a Cogent shock on my DR650. Ive got the DR oem shock gold valved and resprung but I can tell by riding the Bandit that the Cogent is a way better shock.

Re: 1250 Suspension Mods for Touring?

Last night I started to put my forks back together with the new RaceTech springs. After reading the instructions several times, and even the Racetech suspension bible book a few times, I couldn't figure out the length of the spacers. I ended up going to the hardware store and buying a $.30 piece of PVC approximately the same size as the aluminum tube for the spacers. That way I could cut it what I thought was too long, and not ruin anything. To achieve 20mm of preload I ended up with a 4 3/4" spacer.

When I get home this weekend I'll check the Bandit log and see what length I used.

Re: 1250 Suspension Mods for Touring?

Went back and did some reading, Metrick Metal ended up with a 5" spacer on his install. After final assembly yesterday I re-measured my preload and its as expected at 20mm with the 4 3/4" spacer.

Checked the maint. log. I too started at 5.00" and shortened them to 4.300"
