APEX XTX OR APEX

[SRX Boy]

Any sense as to which one is faster. Would suspect the 128" just given the additional track on an XTX but recall seeing something last year at launch time that the XTX was quicker - more traction?? Perhaps the Nytro guys can share what they have seen.

Wow did I open a can of worms

XTX is faster by 1-2mph on top end and that came from the engineers in Japan, when I asked the same question on Sled-talk, the Yamaha Canadian Blog.

I am a groomed trail / lake rider. I have no use for anything longer than a 121 or 128 as the case may be. The 144 with the tipped up rails is a good idea for people who do both powder and trail riding but if you do 90% or more tail riding then I wouldn't waste my money.

You can say the 144 is faster all day long if you want but there is no way it will have a faster top end unless it has more power or taller gears. It takes more HP to turn the larger 144 than it does to turn a 121 or 128. Rotating mass is HP's worst enemy. The 144 might get a bite and come off the line first due to its extra traction but when both sleds are topped out the shorter track sled will be faster.

The hp stolen from pulling the track around the rear wheels is what makes the XTX faster, even with a longer/heavier track. The efficiency of having the tipped up rail is what makes the XTX faster, it has the same effect as running larger rear wheels.

No way the Apex XTX 144 will be faster thru the extreme Twistys than the 128. 144 plush on straights but light & livley goes to Apex SE same as Nytro 121 & Nytro 144. Know your riding style & go from there.

Here's a quote from Chris on Yamaha Blog back in Feb. 2010......

Just a brief update today. I received some info regarding Danes questions over on TY. Surprising as it may seem, the Apex XTX is faster than the SE or standard Apex. It blows it away up on top by a blistering 1.4 kph… that’s .87 mph for the metrically challenged.


Wow, .87 mph? I'd say they're pretty even.

What Chris is saying is it is faster, and it will take off better the SE will handle the corners better but not from behind the takeoff.

We need some snow to figure this out.

This got me thinking that the Apex 144 probably will cost more at the gas pump too compared to 128 unless 144 is geared differently. How does Nytro 121 & 144 compare mpg? Gearing the same?

I can't recall hearing of any fuel economy advantage versus the other, however apparently the reason the Nytro XTX was deemed faster was due to the shape of the slide rails on the XTX. They were less aggressive than the shorties whichs created less friction in the driveline, thus quicker.

Look the nytro XTX are WAY faster on top end than the shorty 121 nytro. I expect the apex XTX to also be faster

Sorry man but the more efficient approach angle of the skid gives it a huge advantedge to all around performance. the older rmk polaris,s had insane top end with longer tracks due to skid efficiency. I owned a shorty & long tracked nytro & have the experience to prove this.
If your doing top speed runs tighten your limiter strap & shallow out approach angle & see top speed rise. Works on any sled.

You are wrong.... Why would they lie? The XTX skid has less approach angle, which would show an increase in Top end, but I guess you know it all....

 

[Super Sled]

Id say the ultimate sled would be the SE extended to 144".......



We're talking about 1-2 mph on the top end fellas, and mpg's won't be much different either with gasoline usage.


But split hairs away if you just have to.......
