Rear Travel on the Apex/Attak is plenty

Some idiot on a maximum sled forum is trying to tell me that for the money I paid for the Attak it should have alot more rear travel and a better suspension. He pointed out that the Poo...py Switchback has 16.5" of travel versus 11.7" on the Attak. My reply was, "what difference does it make?". I personally think if the ride quality is there give me the lower travel for better top end speed. Not to mention the fact when you sit on a Switchback you lose about 5-6" anyway which brings it right in line with the Attak. Any more comments on this topic from the sane people at TY?
 

as far as i know, Yamaha measures true travel which is 11.5", where as pol and Cat measure it different and actually inflating the number.

I don't know if its true or not, but I've heard the same.
 
I think Cat started this "inflated" travel number when they were boasting 13.5" of travel when the max for the other manufacturers was 10". I cannot remember where they measure but this is not true travel of the rear suspension but travel of the kicked up tunnel I believe.

Yammie, I believe, is measuring true travel of the rear axel.
 
Dont forget guys when the #*$&@ end of a sled is so much higher than the front end it makes it tippy,and also the poo is running the 144 and dont go saying its tiped up in the back for better turn out,cause its bull #*$&@,i just came off poos and a bud has the switch back and it still handles like #*$&@,so does the fusion..
 
A lot of manufacturers measure rear suspension travel by the distance of the rear axle arc as it travels. Typically you'll see higher numbers the longer the track, such as Apex-11.6, Attak-11.7, and Apex MTN-14.0 in. FAST measures vertical rail travel to the bump stops, if they did the arc method it would be like 16". Too many manufacturers claiming big suspension numbers that are a bunch of crap. IMO.
 
Measure the way BlueBlood pointed out between the rear axle and the bump stopper on your Yamaha (not SRX and SX :)), it's close to 11.5, remember the bump stopper do compress a bit when you bottom out the suspension. Find a cat, poo or doo and do the same - what did you find?
 
I believe as well that the suspension on the mountain segment machines are meant to float up on the snow not trench. Therefore the more travel the better the floatation meaning you go higher! That being said they are ment to compress at a much faster rate so that they climb up on the snow.
 
THis kills me.. LOL

Ive ridin two Polarises with M-10s and they dont ride any better or as good as the 05 RX-1 i rode.

The best riding sleds iv ridin were the 02 ZL 500 and a ZR 800 but it was the shocks that made it ride so good..

Well calibrated shocks make more of a difference than how much travel you have..

As said before.. the taller a sled is the worse it handles..
 
I don't like Polaris but the 166 RMK has 18.5" of travel and I don't care what anyone says, when the bottom drops out beneath you like ruts, super deep and loose powder those extra few inches could mean the difference between getting stuck on the face of the mountian or even rolling all the way to the bottom or hooking up and summiting. Polaris has been known to make a good mountian sled, I would be more confident taking one of those ugly beasts up an extreme incline rather than something with less travel. I think with a few changes Yamaha could have the best mountain sled. I know power and momentum makes up for a lot but a 166 and 18.5' is hard to contend with. Our snow goes from rock hard to sugary in a matter of inches so I've seen the bottom drop out far too many times to assume I have enough travel, you can't have enough travel on a mountian sled, I hate seeing sleds roll down hills, people too.
 
it's be said before.....it's all in how you measure.
166 rmk has 18.5 but a 151 rmk has 16.5? same suspension, longer rails, you only gain by measuring from the rear bumper.

while travel is somewhat relevent for performance, you can have long travel, stiff shocks and it will ride like poop. It's all in the valving and maxumizing the stroke that available.
 
I love Yamaha but check these numbers, for fast sleds it doesn't make a big difference but when fighting gravity it's obvious who the winner would be. I will be hatted now and forever here but Yamaha needs to realize the extra 118lbs must be dealt with.

SUMMIT 800 w/ 159" - 478 lbs

APEX MOUNTAIN w/ 162" - 596 lbs

KingCat 900 w/ 162" - 500 lbs

M7 w/ 162" - 473 lbs! and only 7 hosepower less than an Apex
 
and how many of them can you bolt a power adder on, make 200HP and ride for 10,000 miles? To each his own.. You buy what you like Ill buy what I like.
