| What about for people like me? I don't want ABS on any of my bikes or reverse on my Vision?
I do think the Vision can hold its own maneuvering in a parking lot, and can certainly show most bikes up in the twisties. I know I have rubbed the tip overs though turns before. |

North Orange County CA | OK Birdneckrider, since you've gone "there" and invoked the gods of science. I have no choice but to dust off my diploma and act as if I was not hung over, or sleeping during physics and algebra. Having thusly established my anti-intellectual bona-fides, I am now going to attempt to explain the effect as I see it.
One of the purposes of the adjustable ride height feature on the rear shock is to help maintain the steering geometry when loaded.
Operating on that premise, it follows that the simplest test to determine if you have adversely effected the geometry is if you have to adjust your mirrors when riding two up. If you do, then it is logical that you have not pumped up the shock enough to maintain the original relationship between rake and trail.
The torque of acceleration naturally causes a chain or belt driven bike to squat a little therefore exacerbating the change in geometry already caused by the added weight of passenger and gear. Interestingly this is the opposite reaction from that of the Wing and BMW (from which most of the comparisons are being drawn) which rise in the back under acceleration due to the torque reaction caused of the shaft drive.
When the rear brake is operated at low speed it has the opposite effect of acceleration (since we don't have full floating calipers), causing the back of the bike to rise slightly compensating somewhat for the geometry change that would be caused by the squatting of acceleration and thus we are going to turn in tighter more easily.
Or it could be witchcraft.....I think. |

New Bohemia, VA | ...ha, how about the headlight. Once the wife and left in the early evening for a dinner date. I didn't bother to pump up the shock since it was just a short ride. On the way home after the sun went down, the headlight was shining into the eyes of drivers and the tops of trees.
I find 60psi sets us at the solo height underway, though it does a Hiyo, Silver, away, and rears up on taking off. |

New Bohemia, VA | ...speakin' of pillions, your ride is affected by how the pillion reacts. They need education before getting on the bike on what to do. |

Extreme Southern, AZ United States | (I believe- I got a b in physics but this was not an area I stayed awake for! The gyro effect would keep the bike upright, and cause you to have a wider turning radius) and I think that the inverted forks also play into the problem, as well as the design of the frame itself.
Well, I don't know what bike you are riding, but my front fork is NOT inverted. I also can drag floorboards with the YL on the back (though she starts hitting me across my back after the second scrape) and don't find the VV poor handling. |

Virginia Beach, Virginia | Ok, somebody help me out. While the fork is conventional telescopic, i was under the impression that if the compression side of the fork was on top it was considered inverted, which is how the forks are on the Vision. I believe most newer bikes ate being done this way. Am I off base? |

I believe most newer bikes ate being done this way. Am I off base? Here is a link on the different types of motorcycle forks for you to check out. http://en.wikipedia.org/wiki/Motorcycle_fork In my view there are three types of forks on most bikes today. Telescopic, Upside Down (USD in the article and sometimes called inverted) and Telelever used on BMWs. See the article And yes.... when I was young some of the old "antique" fronts in the article were on bikes being ridden in those days..... >>>>>> I have a suggestion.........some of us from VA, DC, MD, PA ......get together one of the remaining weekends left this year for a some eats and talk.....do the box in a parking lot and go for a ride. A friend of mine has a great pasta place in Thurmont, MD.....and lots of wonderful roads in the mountains nearby. He owns a Ducati 888 and likes the Vision. Mike |

San Antonio, TX | team222,
Yes, this is one of those times when the posts and the topic have diverged by a few arc-seconds. It happens here........a lot. One could blame it on (as I do) the suspicion that most Vision owners have serious attention deficiencies. If not, why do they purchase such a complex electro-mechanical means of transportation that is simple to operate?
Nutz! I Just took this thread even further off topic! I will finish by saying that......I have to go....I will finish this later.

"serious attention deficiency", that's just SAD. The next time the wife ask what is wrong with me, I won't say, AAD (Adult Attention Disorder) but I'm SAD.
...with that said, let's just get to riding our EMO's (electro-mechanical operations) |

| Reminder = Problem 1: Riding two up I am having issues with slow speed turn in.....the Vision always seems to want to go wide on any sharp turn at less than 15 mph. Same from stops and taking a right or left turn. Update 1. Tried rear brake in above situation two up for the first time.......worked great. Little more difficult turning right to get used to... but thanks for this suggestion. 2. Tried half butttt off seat in above situation but this did not work out that well in most cases as I was not able to get my biggie butt half off at slow speed that easy.....just did not feel right for me though it has worked well for others 3. So far so good.......when I get a chance I will do start the box practice and update everyone on this. Not related to issue re-stated above. Got used stock windscreen from member here and plan to cut it down 1.25"-1.5" since on low setting now with stock screen I am looking right through the top windscreen and the line this forms on backroads and in twisites....and yes I find this annoying for me. Personal to me I know due to my height, but a bit lower will allow me see better. Will report back on this when/if I get it done before winter here Thx Mike

New Bohemia, VA | The Vision offers great windprotection up front and I think if you go with the shorter windshield you'll like it. The problem I have is when the wife unit rides she doesn't like the wind hard in her faces. So it is the tall windshield up when she rides. Me, I could to go Blade and think I'll be satisfied as I don't like looking through the shield either. Tall windshield down has me looking at the edge, hate it, the stock windshield suffices as I can see over it, but the shorty would be perfect I think for both visual and protection. The blade would be just for looks, but I believe it could be raised enough in a pinch to push wind and rain over the head on a stormy night.

New Bohemia, VA | T222 - I'm starting to work more on this for my own good. I'm very comfortable in the close quarters, but I couldn't do the cones at the moment, and I may be able to do the box, as I have, but it don't look pretty like most. |

North Orange County CA | Once again I'm going to suggest looking at the Laminar lip. See the photos and review at the link below.
http://www.Vision-riders.com/bb/forums/thread-view.asp?tid=3973&pos...
My wife appreciates the reduction in buffeting, and I don't have to look through the windshield to get her in the comfort zone.
Is it perfect? Not really; I would love to try it on the 2" over shield and see how that effects the envelope. The lower angle of the vision shield in the fully down position is best for aerodynamics and gas milage. The lip increases the dead air zone.
But being not wanting to replace a perfectly good windshield is what lead me to the product in the first place. So for now I am very happy.

| New topic....not related to turn in issue of this thread. Got used stock windscreen from member here and plan to cut it down 1.25"-1.5" since on low setting now with stock screen I am looking right through the top windscreen and the line this forms on backroads and in twisites....and yes, I find this annoying for me. My wife does not have an issue with the stock screen on the lowest height setting on the back roads and in the twisties........speeds less than say up to 50-60 mph. We have tested lowering the stock screen 1.25" or so will on interstates or areas where higher speeds are the norm and this is ok for her.....so the hope is cutting the stock one down to equate to this will work. Her height of 5' 10" enters into how much that I can cut off the screen. Just for converstation for those that only ride solo.... how much of a lower screen can one put on and still have it not buffet the rider at higher to warp speeds.....say for someone 5' 11" to 6"? Anyone know? Mike |

My height is 5"10"....7" shorter than you.........so my q is how much would you think I have to cut off the stock screen to have the Laminar Lip be 1.25" below the stock screen on the low setting? |

North Orange County CA | I have always operated on the theory that the edge of a windshield should be no higher than parallel to my upper lip. This keeps it out of my line of sight no matter what the road is doing.
The addition of the laminar lip makes the choice of height choice more important because you really cannot see through the top of the shield after it is installed.
Make it an inch shorter than your "ideal" height to compensate for the extension of the lip would be my suggestion. You can always raise the shield but you cant add material after you cut , be judicious.
This website describes more interesting method of choosing height.

Middleburg, Fl. | pollolittle said to let the bike lay into the turn a little more and to keep yourself a little more upright than the bike. That is what I do, in addition to the feathered clutch/light throttle and light rear brake combination. I am currently riding Goldwing but will soon be on a Vision. |

Slow Speed Turn In Issue
