different overstructures, someone explain?

[byeatts]

can someone give an overview of the two different overstructures and how they alter the steering position?

RMK's have a more vertical post.

Non RMK's have a post that is raked back towards the rider more.

The two overstructure top castings are made to provide those angles.

The more vertical post allows for more stability in rider input when standing and riding in steep off camber terrain...the handlebars "turn" more than "Swing" from this position. That lack of "swing" gives more balance in input.

Now... if you are seated, or riding back on the boards..."turn" is there for a more "raked" post because the body position is more rearward.

Many downhill pow carvers seem to prefer that "raked" post as they feel it gives them a more intuitive feel.

NOT having your handlebars centered (in line with the post and not tilted forward or aft) can cause that "swing" to happen as well.

People will adapt to whatever they are riding and I've watched elite level riders do well with both.

Now that being said, I believe that this vertical post on the ProRide evolution from the Dragon was one of the major reasons the ProRide was a leap forward in technical riding.... with less fatigue throughout the day.

Lastly... a raked post has some similarities in concept to "caster" in a spindle on a car or other vehicle.. the more caster, the more stable it is from a rider input standpoint... the less caster ... the more sensitive to input... That analogy translates here as well.

what is the tilt difference in the two overstructures?

 

[B&M Fabrications]

The footwells are about 2" wider as well on the SBA over structure.

The point where the handlebar/raiser mounts are the same on both the designs (Vertical -RMK and Horizontal -SBA).

The difference is as mountainhorse stated!

If you generalize:
The "turn" style gives you a more neutral feel across sidehill angles standing on one side, with the downside that the bars can get in your way when you stand on both runningboards.

The "swing" rendering the bars to turn away from the rider is less in your way when on both runningboards, gives you a bit less leverage at mid range, but more at a high/steep sidehill angle and tricky situations, however when things go south the sled has the same extra leverage to fling you rocketing down the mountain.

As for whats best its all down to rider preference!
