What the heck I thought 2-smokes are evil and bad for the environment! Woohoo

Sumptin ain't right! 👺

And yeah I'm too old to really care if they bring two strokes back but I think the Big Four really dropped the ball when they eliminated making them.

Flame away! Laughing

By the way I was channel surfing the other night and they had a snocross event on and these guys were really going at it and by the sound of the skis they sounded like two strokes but I don't know anything about that sport and was not sure. 😬

That was until the next race came up and the sound was definitely different as they were four strokes.

The next Moto that lined up was bikes snow ski kit mounted on they were all on 450's.

Interesting knowing they can pull 65hp out of a 400cc single 2t efi , get that tech in a bike!

Yamaha shot themselves in the foot when they went to the big fourstrokes in the snowmobiles, they may work on groomed trails but were so heavy they were worthless in the deep powder in the mountains.

Yamaha insisted doing it their own way in snocross. First they only made 600 cc stock class sleds when all the others made 440s. Then the quit making twin cylinder sleds and had to race Polaris based cranks with Yamaha cylinders. Then they went to 4 stroke open sleds. Their snocross teams just never worked really .

It’s an arctic cat, but blue
I’ve been out of the snowmobile loop for awhile but, haven’t Arctic Cats been using Yamaha engines for a few years now? They were/still are sharing components as I understood.

Polaris based cranks with Yamaha cylinders? I don’t remember which engine that was...Let’s hear...

Yamaha stopped making “race” sleds after the Vmax 4 debacle....ISR changed the engine rules the next year after Yamaha spent big bucks developing that sled to dominate oval racing for years to come...

Their 800cc open sleds around 01 or 02, rumor at the races was other brands bottom end with Yamaha cylinder and electric exhaust valves.

Oh ok...no...those were SRX engines with 800cc cylinders...main problem with the triples were lack of low end torque when compared to the twins.

The team had requested to Japan to allow them to secretly run a Cat (or maybe Polaris) twin, but the decision was made not to do that...

They had fitted up a Snocross sled with a modified Yamaha watercraft twin, but never did race it.

Arctic Cat used to use Suzuki motors.

Thank you to the OP for posting about the snowmobiles. As someone who has never seen one, I find them quite interesting. Upon reading the title, I thought "generator".

I saw the snowbike and snowmobile racing on CBS Sports Network after the MXGP was over. Cool stuff!

Johnny Depp, how many Beta motorcycles / off-road threads have you started that were NOT in the off-road section?? Did you even know that VitalMX HAS an off-road section. :-)

They get some monetary value from not cleaning up beyond wheelie boys / sensitive threads. You are one of the many to take advantage of it by posting non-MX stuff in the MX subforum. Yes, I am thankful for your news and info on the off-road bikes, but you are NOT the one to yell "non-moto". :-)

A 300 TPI has like what? 48 hp? 55~ with a VHM head... So the tech is already here.

Take a look at views vs. responses, total click bait.

Let's not forget my violation of the E-bikes in Moto. And Beta IS Moto.

As Motocross Action stated once before, Light weight 2-Stroke Performance Engine Technology with EFI or TPI is the future. This is a Milestone event for some one like Yamaha. With enough of us not being Stupid to buy into the 4-Stroke Hype, the OEM's will be Forced to come out with a similar Motorcycle Engine.

Since Europe is going to 300 cc Bikes for a large part of Off-Road Riding, it's only a matter of time when we see 2-Stroke 350's, 400's or larger.

Guys, they put blue bodywork on a Cat Alpha One. The Ctec2 engine is a Cat engine, Yamaha just slapped their logo on it.

Its literally nothing.

100% correct.

Its a weird relationship between Cat and Yamaha.

What would happen if you would use this engine in a sidecar?

It would get passed by the Rotax 850 Ski-Doo uses.

It would also burn more fuel and oil by a wide margin. Ctec is a copycat of BRP`s E-tec direct injection system.

Negative on your last. BRP has E-TEC patented. The Textron DI engines are more of a hybrid, semi-direct injection.

If they weren't attempting to copycat, or at least market it as a very similar technology, they wouldn't have called it Ctech.

SKi-Doo has a 600 EFI twin making 20 more hp for less money. In the snowmobile world that engine is going to flop hard.

Well, it is also kinda just a broad lazy marketing practice in the motor industry as a whole to brand some technology TECH, TEC, or Tek. Similar to putting "ECO" in front of anything that runs cleaner, or "i" in front of anything digital:

Acura: iTech
Damler: Bluetec
Suzuki: S-Tec, M-Tec
Ford: Duratec, ZTEC
GM: Vortec, Ecotec, S-tec, Etec2
Nissan: N-TEC
Honda: VTEC, SH-Tech
Kawasaki: KTech
Toro: r-tek
John Deere: Powertech

Probably be more interested in how much this Engine Weighs vs a 450? I did find the Weight of a KTM 250......which is 7 lbs Heavier, ..........not so good.

250 SX-F ENGINE
The 250 SX-F engine is known to be the strongest engine in its engine class. And with updates on valve timing, exhaust, airbox and EMS the entire power pack produces even more torque and power across the entire rpm range up to 14,000 rpm. Its compact architecture contributes to an excellent mass centralization. This supports the easy rideability of the bike together with a --------------------- (low weight of only 57 lb) -------------------------, including the incredibly beneficial electric starter.
