Ski-Doo Engine Technologies

Our engineers have come up with the answer to the age old question: Is a 2-stroke or 4-stroke engine better? With our new Rotax 600 H.O. E-TEC and 1200 4-TEC engines, the answer is YES.

Our founder, Joseph-Armand Bombardier, was always looking for new ways to make life better through technology. Thats what led him to create his first snowmobile at age 17 from a Model T and the first mass-produced snowmobile, the Ski-Doo, 50 years ago. That same spirit of innovation drives us every day to make snowmobiles that make you a better rider.

@vdzrussell Learn how to set up your sled

[vdzrussell]

I'm only 180 lbs and i still yet to find a sled that doesn't bottom out on stupid shit.

scrogy is a retard

@rdyjur "whereas a two stroke there is a slight delay in the power until you hit your max rpm"....the word you are looking for is Powerband and it doesn't occur at the max RPM. And scrogy is correct a 2 stroke will always produce more power and torque (yes I said torque on purpose) than a 4 stroke for the same displacement normally aspirated. It's physics.

[SCROGY]

@rdyjur It's is not awful. It's physics dude. You can't argue against it. And it has NOTHING to do with being a bike or a snowmobile. It's about the laws of nature.  When there's combustion on every turn of the crank you're going to develop more power and a harder hitting power. You need to learn what a logical fallacy is and quite frankly you also need to go back to physics 101.

[SCROGY]

@rdyjur I don't know where you got that from but it's false. Two strokes definitely hit harder and make more power. 4 strokes do not generate better power through the whole RPM range (their RPM range is wider). They don't hit as hard and thus just feel like they have a wider power band. Why do you think 4 strokes with double the cc were allowed to compete against 125's (250 4 strokes) and 250's (450 4 strokes) in AMA motocross? Because a two stroke essentially makes twice as much power.

@SCROGY

I am definitely a 2 stroke guy but i've rode a lot of both in mountains, trails, ditches, praires, etc. you're argument against 4 strokes was awful. stick to your 1980s dirt bikes

[rdyjur]

@SCROGY

a 4 stroke engine generates better power through the whole rpm range whereas a two stroke there is a slight delay in the power until you hit your max rpm. 4 strokes are waay snappier!yes motor has much more to it making it heavy and hard for guys like you to figure out. and once u learn to use compression braking u will rarely have to use your brakes unless you're flying down the mountain at mach 1. suspension is meant to be set up for your style when u buy it, with basic tools

[SCROGY]

Sorry Ski Doo but you can't tailor a sleds suspension to everyone. Riders of different weights and skill levels need different set ups. That's just physics and you can't solve that problem without adjusting. FACT.

[SCROGY]

2 strokes - More power per cc. More SUDDEN response (They hit harder). Simpler design. Easier to work on. Less compression braking. The only advantages 4 strokes have come BECAUSE they make less power per cc. 4 strokes blow. I hate 'em.

And Honda did this Di two stroke thing 20 years ago. It was called the Honda EXP. It had two injectors on the head and shot raw fuel and raw gas into the combustion chamber. They used in on a Baja dirt bike and then it disappeared.
