I can't believe the extent we argue about things sometimes...
Yet it still keeps going.
When the sidestand is used, the tripod is more like:
``X``
`````
`X```
`````
``X``
Agreed. Of course the 919 seems to lean a fair bit further, but for this purpose, this is acceptable.
which is a lot less stable than the centerstand:
``X``
`````
`````
`X`X`
`````
No matter how much you sweaR at it.
see this is what I don't agree with. Your diagram is a little inaccurate. ( sorry. :) )
It should be more like this:
``X``
`````
`X`X`
`````
`````
The rear half of the bike is typically in the air. The centrestand, to my eye, raises the bike's centre of gravity, changes the height ( therefore potentially making it a larger obstacle) and makes it less stable, because it's balancing on 3 points spanning a little more than half the length of the bike. Whereas the sidestand uses the entire length of the bike, doesn't change its height or centre of gravity. In my mind, and I'm sure someone will be able to point out why my thinking is wrong, that should make the bike more stable...
Now, this is all for parking on flat ground, if you park on a hill, you're likely to find problems, but here's the thing, on the sidestand, you can take advantage of the strength of the transmission to not let the bike roll forward and off the sidestand. The centrestand has the rear in the air, no such stability.
And you can prevent the sidestand from sinking witha crushed popcan, or similar under it...
