I watched a program on last night where they showcased Polaris running the Iron Dog race in Alaska. I was shocked to see no 800 poos in the race they all rode 600. I wonder why that is????
Iron DOG
- Thread starter beamslayer
- Start date
....maybe the race is for longer than 1000 miles. 
600 only
Iron dog used to be 500 only years past. Means the sponsors buy less fuel

It only covered poos so I do not know what everyone else was riding.
What is the deal with the bright orange 3/4 helmets?

Sheetmetalfab got it right. I decided to look on their website, here is what it said in the 2012 rules.
2.2. Two-Stroke Engines: 600cc maximum displacement.
2.2.1. (or) Approved ISR 4-stroke models:
Yamaha Nytro and Arctic Cat F 1100 (non-turbo versions)

The race is only 600's so everyone is on them. I ride polaris but if you are doo bashing you might wanna take note that doo won this year..... And the open face helmets make it easier to drink and eat when you are haulin ***
Do they pick their own course or is it more or less a trail.

I know the real answer was allowed max displacement is 600cc, but I liked this answer the best, lol!

FYI, the insinuation is that the 800 motors couldn't make it 1,000 miles, so they had to use 600 cc motors. It was a joke I bet. Well, mostly.....
But come on, these ticking time bombs are the funniest sleds to drive, they really are. That's why we put up with the motors -- the chassis are the best.

None of these sleds are anywhere near stock, they are beefed up, extra aluminum fuel tanks on the back/sides of the sleds. Its an accomplishment to even finish this race... Most years over 50% who enter dont finish.
The poo 600's have done great that last few years proving that rush rear end can take a beating!
It is 600's mainly for the safety of the riders if they allowed 800's you would see over 100mph on several parts of the course and when your going 2000 miles fatigue, ect it can put a hurting on people. This year someone was in intensive care from a wreck, and its not uncommon for a few riders every year to windup injured.
600cc better fuel mileage, they still haul ***, and its just safer for the racers..
Each racer has a gps that you can track exactly where there at ect due to it being literally in the middle of nowhere for hours of riding.... But anyone can check there website and see where anyone is. Its a really fun race to follow via there website gps tracking! Your talking around 5 grand to enter the race, you need a practice sled and a race sled. To run the race your looking at around 50,000 $ and some air plane support is key!

Thanks for the answers.They sure look like they take a beating.Those helmets really threw me off I kept thinking a full face or one of those flip up fronts would be warmer never thought about eating and drinking.
I must admit I really thought they used the 600 because it has been such a bullet proof engine.

I was joking....mine only made 947 miles so I wouldn't have made it to the half way point. Pro is easily the best chassis out there. Leaving it at that.
I was under the impression that the 600 limit was due to engine size from the past. Limit the size so the times were more or less consistent from past race times. Just like the limit on 4 strokes is 80 hp (Nytro and F1100 class Non Turbo), not many of these make the run. Weight and trail breaks them apart. There is also a trail class run before the Pro race. Teams from the National guard, husbands and wives and every day guys make this run. You should all look into it.
I Looked at 3 Doo iron dog sleds near my house several times this year. Lots of miles on the trainers, refab, better parts, tough engine parts, building up of weak parts you name it they add stuff. I also think the top Doo riders ditched the r-motion this year, breaking them in training runs, in favor of the older skid.
As far as speed goes, One team riding the sleds I saw set a record,they made a 90 mile run in 56 minutes that takes me close to 2 hours on a a trail sled hauling A$$ and over 3.5 hours on a work sled. They pass you nicking the tops of the pressure ridges 5 ft tall like mad men or orange devils.
The orange hats allow for safety and identification (from the ground & air, easy to see from a helo).
These guys put duct tape on their noses, cheeks and sides of their faces to protect from frost bite. at -30 or -40 70 mph can freeze skin fast. If you are interested here is the official site and rules for 2012. Yellow highlights are rule changes for 2012.

All except the Poo 800 in the Flush chassis

The 600cc engine limitation is an ISR requirement and the Iron Dog aligns with it for insurance reasons. Also, the intake and exhaust systems as well as the engine are required to be OEM - no mods to those componets. Everything else is open to the imagination. The use of the open face helmet allows the helmet to stay on while drivers eat, drink, work on sleds, etc.

the orange is a requirement in most racing circuits, stands out against the white snow.
