the bike looks just like yours.
Thanks, Doug
Hey Doug!
This is pretty common on these bikes. I'm guessing it's one or more things ... all of which are cheap and easy to fix.

1. worn chain and sprockets. riders neglect the front sprocket. really causes a bad feeling through out the bike. Same with badly worn chain. Get the best quality chain and sprockets you can find. OEM Suzuki make really good, long lasting spockets. DID chain is best .... 525 X Ring please!

2. Cush drive rubbers. Pull rear wheel. Replace Cush rubbers or stuff cut pieces on inner tube as a temp fix. REally smooths our DR drive line.

3. Check wheel bearings ... especially rear Hubb bearings (there are three on the dR ... two for the wheel, one for the Hubb. Have a feel.

Come back after you've checked these things, let us know.

(PS: followed many of your rides ... fantastic stuff Doug! )

Doug,

Check and make sure the motor mounts are tight.

EDIT never mind I see you already checked.

I had a weird vibration once - fixed it by replacing chain and sprocket and going back to 525 with bolt on front sprocket vs using retaining clip.

Nope. Totally different engine.

#2 worked for me... it turned out that worn cush drive rubbers were making a vibration exactly like you describe.

If you live in Australia, 18-30,000km, rest of the world, 30-60,000km. All years.

The good news is you've got probably as much chance of it happening as winning the lottery.

1996 through 2013 are all the same, so you've got a wide availability. Can't help with sourcing though, someone will be along in a minute.

Mine has almost 30,000km now. I'm getting into the zone. I don't buy lottery tickets so maybe I'll be okay with the DR too :)

Steph, if you're really concerned, there is a thread concerning the issue. I think it's entitled "DR650 3rd Gear Blow-ups" or something similar.

I checked all the stuff, cush rubbers looked good, bearings feel fine, fr sprocket is tight on the shaft. mounting bolts are all tight, no cracks anywhere
I guess my friend is just gonna get a numb ass this week.

I'm leading a 1k mile trip thru Bulgaria & Romania, most days will be 200 or so miles on small roads, so it shouldnt be that bad.

Thanks for the ideas tho!

Doug

Hi Zdiver1

Here's a 320 EBC on my DR. Make sure the clamp at the arrow is secure, if the brake line slips down, the rotor will cut it. This happened to some guys when adding stainless brake lines.
