Default delicate nytro

so im thinking about buying either an xtx or a switchback assault, and i think the xtx is the sled for me. My only holdback is, are they as delicate as they seem. It just seems like everyone who owns one bends it.

Yamaha made improvements to the subframes in 2009 and 2010 but they still have issues and need gusseting to prevent them from bending.

The last update to the subframe was in 2010. The current part number for the 2008-2012 Nytro subframe is 8GL-21940-02-00 so no changes have been made since the last 2010 revision. The frames are still weak and most likely will remain that way until Yamaha makes a major change in the Nytro....like adding power steering. I've seen many bent frames since 2008 but I've never seen or heard of a bent frame after adding gussets.

If you buy a 2010 or newer you will not bend the front end. Unless of course you plan on jumping it 20 feet in the air on a hard landing, good chance you will but that goes for any sled you buy.

I have not seen or heard any reports of people having to change the front end on any 2010 or newer with regular agressive riding.

Well add me as one. I was climbing a hill last year and hit a hump of frozen sand, bent the frame. Over $3000 in damages. Thank god for insurance.

Hey Griz, where do I find those gussets?

As for the Assult vs XTX question, that was the same decision I was faced with. Obviously I went with the XTX and don't regret it, at least not yet. My friend snowchecked a 2011 Assult but I have not had a chance to try it yet. Who knows, maybe back to Polaris next year...

LOL, come on... I guess if I hit a rock with my front end it would do damage. Maybe they're tanks in weight but you can't start smashing into things like a tank and expect it to hold together.

I've seen a couple bent 2010 subframes and I've also heard several reports of others bending also. Yamaha made a poor attempt to improve these frames by first adding gussets in 2009 then claiming they improved the gusset material in 2010. The bottom line is that their gussets are weak and improperly placed in the frame. I've been working on these frames since 2008 and have had many discussions with other Nytro owners to try to understand and correct the problem. The gussets that I designed are made out of 10ga chromoly steel and so far have proven to be effective in preventing subframe damage. If you need more information on subframe gussets you can email me at grizztracks@roadrunner.com.
