I haven't seen one in any of the pictures nor mentioned anywhere, conclusion no damper for the Street 500 or 750. But the question, does it need one? Will you be adding one?

I haven't seen anything on this from the pictures and information put out by the media or harley. Maybe we'll find out more about this stuff as we get closer to it's release?

Maybe this is an embarrassing question, but...

What is a steering damper?

New to motorcycles here so I'm just trying to learn about all the parts and lingo and such.

no worries...




they go in all sorts of different locations depending on the bike. the point is to keep the steering true. its designed to combat unwanted movement/oscillation of the steering. Not all bikes need one however.

I personally wouldn't worry about a dampener. I have owned several bikes, and have never seen the need for one.

yea i think the Street 300/750 have enough of a head angle that you don't need one. All sport bikes need one however because of their severe upright head angle...

yep. plus I don't think any of us will be changing directions quickly enough to require a damper.

you can always add one aftermarket if you feel the need. even alot of sports bikes don't use them/come with them

If the bike has enough trail a steering damper is unnecessary. Many sportbikes use very little trail to allow the bike to turn in quickly and use a steering damper to control the bike at higher speeds. Trail decreases as the fork is compressed and as the bike is leaned over in a turn. Trail also decreases as tire diameter decreases. Enough trail to make a sport bike with a 17 inch front tire stable on it's own without a steering damper in a high speed race track corner where it is cranked over 50-something degrees and the suspension is compressed under cornering loads will make the bike tough to chuck around in tight corners. So sport bikes come with precious little trail and use a steering damper to control steering shake.

Between the 19 inch front hoop and raked out steering head Sportsters have adequate trail in their stock configuration. But what did all the 883 racers do to their Sportsters? The put 15 1/2 inch long shocks on them compared to 11 or 12 inch stock shocks to get some cornering clearance for racing. The drawback with this is that raising the rear up like that reduces both rake and trail up front. A Sporty can afford to lose some rake, they really have too much, but the amount of trail lost was enough that at track speeds with the amount of cornering clearance they gained, they did not have enough trail to remain stable in high speed corners. That is why you see steering dampers on 883 Battle of the Twins race bikes, and on the Vance and Hines XR-1200 race bikes in AMA racing.

The better alternative to a steering damper is to change the triple clamps to reduce steering offset. For European XR-1200 racing Harris sells such a triple clamp through Adrenalinemoto of the UK. Reducing steering offset increases trail (go ahead and draw the geometry to see for yourself) and eliminates the need for a steering damper, at the expense of heavier steering on turn in. If you are a big boy like me, that is an acceptable trade off. My K100RS Frankenbike uses reduced offset triple clamps from another motorcycle so I could raise the rear with a longer than stock shock and lower the nose by sliding the fork tubes up 25 mm in the triple clamps. No steering damper and stable in corners up to 140-ish mph with loaded saddlebags. Don't try that on a stock configured K100RS, you will experience the scariest death wobble imaginable as I discovered on an autobahn outside Bonn Germany late one night.

Yup, it's going to be a WHILE.
I'll be surprised if people make the jump that quickly.

Livin On, a Steering Damper? Are you going to put a sidecar on your Street? Or do you plan on track racing it? If not I wouldn't worrie about.

do people really still have sidecars now? dont see them around anymore
Yes. Harley sells them and I think every Ural model is equipped with one now. Urals have a powered wheel on the chair which makes them popular desert sleds. There is a certain faction within the BMW fraternity with which side cars are popular.

Well I can now tell you that you are wrong. The XG750 with the Velorex 563 Side Car has plenty of get up and go from my own Personal experience. I'm here looking to see if someone has already installed a steering damper on an XG750. I would like to do this for the side car rig.

They come in a universal fit. You can mount one on any bike. You need to figure out if you want an adjustable one and how strong you want. I would wonder why you need one on a Street unless it has a sidecar or been triked
