Lean Angle

[TwoSmokeDS]

What is the proper lean angle?

I'm trying to do use geometry to figure out how much of the side stand to cut off after I lower the bike 1.5 inches.

Thanks!

You could measure the existing lean angle with the OEM setup on the sidestand, then use that as your reference after making the suspension mods.

My guess is that if you lower the bike 1.5" you will cut the sidestand at a point measured 1.5" up, vertically from the ground. (as opposed to along the length of the side stand)

Problem is that I already lowered the bike. So I don't know what the OEM angle is.

I just keep chopping a bit off, put it on the stand and look at it!! If it looks right I then weld some flat plate to the bottom of the stand, if it doesn't I remove another 1/2 inch and check again.. Lots of work, but I get there in the end..

You could also use a 2x4 (1.75") under the tires to raise it back to stock height then measure.

Adjust your measurement for the extra 0.25" height you get from the wood, if being exact matters.

If being exact matters, also put something 0.25" under the sidestand, then measure a point on the sidestand that is 1.75" vertical from the ground.

Or, find something that can go under both wheels that is 1.5" and make the measurement.

Hope this helps

According to my calculations using the SWAG method, you should cut 1.25550463 inches. Give or take.
As always I reserve the right to be wrong.

Find the tipping point of the bike and adjust the sidestand to hold the bike .025" above that point. Test outdoors; a strong breeze should tip the bike, or loading any cargo above seat level and it should go over.

This is apparently the method utilized by german engineers about 20 years ago.

Now go buy a hockey puck and make that your sidestand foot. Perfect angle.

(currentHeight/previousHeight)*(lengthSidestand)=newlengthSidesta nd

OR

lengthSidestand - ((currentHeight/previousHeight)*(lengthSidestand))=amountToCutOff

OR

Eyeball it. You reduce the hypotenuse (sidestand) an equal ratio to the reduction of the leg (vertical height.) If you lowered it 10%, then chop 10% of the stand.

OR

Bend it.

Personally, I need a longer stand. My bike is +1.5" in the rear and it leans wayyyyyyyyyyyyyyyyyyyy over.
