So me, being a big lover of the old school triples, got bored in my math class. I love the idea of the big 4 getting into a horsepower shootout like it was back in the day so I decided to punch some numbers and get an estimate of some HP numbers that new two-stroke triples would be putting out. These numbers are based on the performance of both their 600-650 class and 800-850 class and I set a benchmark for each engine at a 1000cc triple as it was the easiest to use. Ski-Doo came in at a 200.7HP, Polaris at 201.8HP, Arctic Cat at 210HP and Yamaha at 212HP. Since I wanted to use the idea that each brand was using their own engine, Yamaha's was a bit more difficult to calculate as they aren't currenting making any big two stroke engines themselves. I had to find the performance increase perentage of all the brands and apply that to the numbers of their last triple, therefore Yamaha's is probably not as accurate as the others. Even a 900cc Ski-Doo E-TEC triple could possibly be making between 174-188 horsepower, and these are numbers from the factory. Obviously, there are a lot of variables involved with this, and I'm not saying that this would be precise at all. However, I thought it was pretty fun to see the possibilities that could be had with today's technology. I truly do believe that there could be a market for these sleds.

I would be the first inline..

I would be second in line, they are great out east not in west, but been 25yrs out west and just moving back and first thing I am doing is looking for a big triple, lol

I've owned 2 triples (Polaris 650 Indy and Cat ZRT 800) in my lifetime, nice smooth running engines. Don't believe you'll ever see them again from the manufacturers. They are heavier, larger and more expensive to produce with no real performance advantage over the current twins. With prices skyrocketing on all new sleds, I don't see a real big market for any new triples. As for HP increases, most sleds are used for trail riding and trail machines are already overpowered for most areas.

Yeah, I agree. One possibility I can see them doing however is making them a special order, similar to the Ski-Doo 600RS. With the heavier, larger, and overpowered thing, they still wouldn’t be as heavy as the Yamaha four strokes, and a lot of people love those. Reliably making 200+HP in a setup lighter than something like a Sidewinder seems pretty fun to me.

I would sell a testicle or both for a new skidoo etec triple. I have two triples right now and you cant beat the sound and the long legs at the big end.

There has been tripples available since at least 2009. The new tripples are infinitely more reliable than the old 2 bangers. :)

In all seriousness why ? Any more tightening of the emission regs 2 strokes are done they barely get by today.

If I was running the ship I'd be looking advancing light weight 4 strokes that can be used across platforms.

New four stroke triples more reliable than old two stroke triples? Obviously. However, they don’t have the same sound, same power delivery, same ease of maintenance. Pretty much nothing else compares. A new triple could have similar reliability to a new 600cc twin engine, a lot of which get 10000+kms. Two strokes will not be done anytime soon regarding emissions. They are always finding ways to make these machines cleaner. Until a four stroke comes close to the weight of a two stroke at a similar displacement, and can produce the same power reliably, there will always be a demand for two strokes.

Start your search for a diamond in the rough that was purchased and never ridden, then go through it, and have an old heavy relic that sounds amazing with a set of pipes on it in your stable to ride when you feel like getting wild. Tis what I did, I ride it maybe once a week for an hour or two when I know the trails will be flat, hard and fast.

A direct injected 1000 triple. I could only imagine how fun that would be out on the lakes.

Everyone keeps saying they are heavy. That was the old chassis triples. Weight wise it would be one more cylinder/piston and the crank and case extended on the existing twin. That extra weight will be low slung in the sled so not much difference felt. Factory make it singe pipe then the aftermarkets can make the rest.

Will be clean burning, great on gas and reliable as most well built triples back in the day had those characteristics compared to twins. Can see them in a little bit lower chassis of todays sleds pulling 185 stock single pipe and 200-210 with triple pipes.

Benefits would be no more hitting a wall about 100mph and creeping. Guessing steady pull to 110-115 then a gradual climb in stock form.

A lot of us are adrenaline junkies and would love the thrill they would produce.

Completely agree with you there.

I say try it in the sport line up tripe EFI to keep cost down.

Perfect use of math class. Well I must admit math is a subject you need a good grasp on no matter what you do. Truth be known, that was my strong suit so I drew out electrical schematics for my home projects during math class.
