Rx-1 VS. Rs Vector front spindle has got me baffled??

[welterracer]

I have been doing some thinking on this!!

Why did they put a shorter spindle on the vector and not on the rx-1 and warrior?

Obviously the spindle hight is going to make the sled handle better (seeing how the sled will sit lower) and the rx being heavier needs it even more than the vector does!!

JUST DOESNT MAKE SENSE TO ME??

I wonder if there is anyway to chop down the stock spindles to help with the handling?

Your thinking would make sense if your sled had only a front suspension. However, you have a rear suspension to think about, and the two work together. RX and RS have different rear skids (along with different motors, weight, etc.), hence the different changes. A lot more going on with shortening the spindle than just lowering cg on the front end.

Does the rage and warrior have the same front suspensions?

 

[Swiss Sledder]

The Yamaha web site indicates the exact same chassis specifications for both the Rage and Warrior.

It doesn't actually lower the CG, the arms end up going from the bulkhead down to the spindles at a steeper angle. Vector/Rage have different arms as well as spindles, the shocks are connected to the arms in further towards the body. What it does it changes the roll center to compensate for the change in weight.

Regardless... If it good for the rs it should work well on the rx.!

Nope. RX motor is too heavy for that geometry, needs longer spindles sticking more straight out. Short spindles will make it crazy in corners.

There is only a 22lb difference between the three cyl. and the rx motor!

THe weight difference in riders can be more than tripple that!

LB is right if the spindles were closer in like on RS the RX would be much tippier in the corners. The wider stance compensates for that extra cylinder. A really light rider could probably get by but a heavier guy would make it so top heavy it would tip that much easier.

 

[welterracer]

O.K.

Now lets say a 275lb rider buys a rx vector! Now because he is so heavy will it handle like crap?

They say the vector handles as good as the viper.. The viper DEFINITLY Handles better than the rx does!

 

[Srxspec]

You can't use the difference in rider weight in reference to two different styles of front ends using two different motors. It's all about how the weight of the motor is placed over the front suspension, thus the difference in the a-arms & spindles & housings. The Vector front suspension geometry will NOT work on the RX-1. If it would've worked Yamaha would have changed it as well!

How about these spindles.

 

[LazyBastard]

If you look at that pic, you can see that the front suspension is very clearly NOT working. The outer arm is WAY compressed and the inner is WAY extended. That is obviously just intended to haul that sled down to the ground. It would feel like CRAP on a trail.

Which sled are you looking at. #85 and #84 have the long travel shocks on there sled, which is the same as stock, for travel. But it does sit low, we have 2" blocks to lift it up for more clearance from the bellypan to the ground. We ran the rx-1's 2 years at the Soo I-500 (MI.) and it does get rough at the end of the race, just like some rough trails out there. 2 to 3 foot monster mogels coming out of the corner's, and bumps all the way down the straitaways, at top speed( 100-115 mph ) and the rx-1's ride and handel just fine. The#85 sled in the picture broke his torision bar thats why it looks like the sled is rolling to the right, but the driver seem to like it that way after it broke. :?

 

[LazyBastard]

Ah, I guess that would explain that....

Of course, having the front end sitting so low does change everything, so as a comparison, its really not applicable.
