Vision USS Handlebar dimensions
 
Does anybody have a Vision USS handlebar and reasonable measuring skills?
I'd appreciate it if someone could send me some dimensions:
-angles of the bends
-width of the bottom, through the stem between the first upward bends on each side
-overall width of the bars at the grips
-how long is the bar, measured from tip, through the curves, across the stem to the other tip (in other words, end to end if it was a straight piece of tubing).

Since I can't seem to find a Vision USS bar for sale, and the equivalent cruiser bars are heavy steel, it looks like I can just buy some 22.2 diameter 6061 aluminum tubing and use a tubing bender: a DIY handlebar.

So if someone can help me out with the dimensions on theirs, I'd appreciate it (or if you want to sell me yours, that might be nice too).

Thanks,
Rich

I attached a 3-view drawing of my Vision USS handlebar so you can
have your machinist make another one from a 7/8" diameter steel tube.

No, sorry, I don't want to sell my Vision. There's a Yahoo! Vision riders group. Check there.

This is about how half the handlebar looks from the front. It only shows half the actual handlebar, from the top of the handgrip to the center
of the stem. It appears to have a single bend in it. But it actually
has two bends, a downward-angled horizontal bend at A and a right
angle at B.

From A to A on the opposite side is a straight line. From A to B is a
straight line. From B to C is a straight line. The two bends are curved, but I don't know how to measure the radius of curvature.

I made three-view drawings below where I switched from | and \ and - to asterisks to represent the metal tubing on two of the views.

Took these measurements today. Two bends per side, inboard bend of 27.5deg at A and outboard 90 deg. bend upward at B, end of handgrip at C.

Dunno why bend locations are slightly different left & right, maybe they
are supposed to be the same? maybe not? Maybe my measurements were off?

-------------------------------------------------------------------------------
all measurements in decimal inches +- 1/16 in. and in
degrees +- 0.5 deg

A - location of inboard bend
B - location of outboard bend
C - top of handlebar grip
-------------------------------------------------------------------------------
NOTE 1: For clarity, only half the handlebar is shown, from the handgrip to the center of the stem.

NOTE 2: Distance BC was measured with handgrip in place, so it is from the centerline of the horizontal tube to the top of the handgrip.

NOTE 3: A is 7.75 on RHS; 8 on the LHS; dunno why the difference

NOTE 4: Drawings are NOT to scale! I used leading dots ..... for placing labels on drawings---just because this web page's text preprocessor deletes spaces. So ignore the dots.

Can you try drawing it on paper, taking a picture with your cell phone, and posting that?

Forgot to let you know that the hand grip area of these handle bars were shortened 4"-5". I do not wish to sell them as I'm building another Vision with USS to go with this one that I just finished.http://bikeforums.net/attachment.php...hmentid=307217

I just an OSS conversion on my Vision 40, and I'm thinking perhaps a slightly shorter stem on the mast pointing forward would give you less tiller effect? Curious about that...that would put the grips and inch or two closer to the seat though. I've got about the same configuration set up, but my stem is quite short.

I'm interested in converting my 2000 ( I think ) R50 from USS to OSS. I base this on a Lightning P-38 test ride in Portland years ago. I think the R50 is twitchy in comparison, which I attribute to the USS. Does anyone have an OSS kit collecting dust that they'd want to part with? Or any thoughts on my observation? Or perhaps suggestions as to how to convert the Vision? Right now the Easy Racer and the Greenspeed GTO get all the use while the Vision has become a dust magnet.

You could probably piece a setup together using RANS parts. They still make all the parts required, whether praying hamster or open cockpit.

40spokes,
Check out this guy on eBay as he sells a complete kit for what you need:
