I am trying to decide whether to buy a 2007 136 Attack or a 2007 121 Apex. Both are nice sleds. Did Yamaha quit making the attack? I couldn't find it on there website. Also what are advantages and disadvantages between a 121 and 136 track? I typically put over a 1000 miles a year on mostly groomed trails but occasionally go off trail. The 121 I had last year seemed to get stuck in deep snow constantly. Will the 136 make that much of a difference? What should I do?
Thanks for the information, look forward to reading the replies.

The Attack is now called the Apex LTX ...My brother has one (Attack) and loves it...

Attak or LTX. Much easier to get it to hook up. Have you thought about an XT-X? I was in the same boat as you. I was SURE I was going to getting an LTX or RTX. Then settled on the XT-X and I am extremely confident in my decision.

A lot of 'flotation' depends on the track. The ripsaws have great traction on hardpack but if your going to go in anything deep they just trench through it. I have a 121" predator 6 pitch track and wow my 121" pig floats on the little powder I get to ride in. I'm not talking moutain riding but i never have gotten stuck since I put it on. I got stuck almost every off trail ride on the ripsaw and I did far less of then now.
Also there is only like 4" more track on the 136 then the 121 but the 136 will push a bit more through a turn. If your a off trail guy go 144 and a better track, if your a on trail guy stay stock, if you may get off the trail once in awhile say less then 5% of the a better track like the carve/predator would probably get you by.
If your still confused then evaluate the trails you ride, lots of twisties? Stay 121, lots of straight, 136 might ride a titch better.
My summary:
121 - stock hardpack trail only
121 - Predator/carve track off trail sometimes ok
136 - trails that are long and have a lot of traffic and chop
144 - off trail say more then 20-30% of the time, not a lot of twisties.

The Attak is also more comfortable over the bumps then the short track. The Nytro XTX is awesome on the trail, corners nicely, and floats well in moderate powder. The only downside is the lack of wind protection.

Been around here long enough to notice more guys say they like the 136". I wouldn't have one, but am very likely a more aggressive rider than many, and have a long history with big, heavy, short track performance sleds. I tried a long track and didn't care for it. A lot of your decision is likely to be based on what you've been riding, and what kind of riding you plan on doing?
Kinger brought up track performance. While many like the Attak, most will admit the stock Ripsaw, on either the 121 or the 136, suck in any type of loose conditions. I'd add the Cobra track to his list of recommendations for a good loose snow performance track.

Excellent point, a smaller rider sometimes struggles with the longer tracks. Since I am over 6'2", 260, the 136 is just the ticket. Never had a problem with the Ripsaw in the Northeast, durability hasn't been an issue.

I;m 5'8 200 so maybe I should stick to a short track then. I just didn't know if I was missing something with the 136?
What have you ridden in the past, x country, muscle, trail luxury? How about ridding style? It's a personal preference, at this time I would not go back.

I've been riding sleds since 1980 and always looked down at a LONG track, I've always told myself they don't handle, hard to steer in corners bla bla bla...but once I tried 1 out WOW!!! this is much stabler at high speeds, rides much smoother, hooks up real good out of the hole so I "snow checked" traded my '05 RX1-ER 121" spring of `07 for a APEX L-TX 136" and I can't beleive what I missed out on, I never looked back and I don't think I'll ever go back to a so called shorty 121" you get her set-up properly to your riding style and it handles as good or better than a 121" hands down! I'm 6'2" 230 w/gear and I'm a semi aggressive rider, meaning I slow down when the riding get rough and let her go on nice railbeds and lakes, I love HIGH speeds, I had my rear shock calibrated, re-sprung and re-valved and added GYTR on the front shimmed and re-valved also and she rails, the other thing is LTX'S (136") seem to run faster top end than shorties (121") now I'm talking STOCK. Now this is my opinion and riding experience

I stretched my sxr 700 to 136 and loved it. The '05 "candy" mono sucked me in, traded it in a year latter on the Attak, much happier.

This topic has been discussed many times before with the same results. By my un-scientific calculation, 75-80% of the responses were for the longer track Attak.cmharcou said:I typically put over a 1000 miles a year on mostly groomed trails but occasionally go off trail.
