What's the latest with Arctic Cat's proposed 650cc purpose built snow bike?

I understand that Artic Cat has been toying with the idea of building a 650cc 2 stroke purpose built snow bike.
This would NOT be a converted motorcycle......... It will be purpose built!

Now I'm not talking about the proposed Artic Cat SVX 450 4 stroke snow bike......... this will be a 650cc 2 stroke purpose built snow bike.


The single cylinder 650cc 2 stroke engine will be FI and will have an AFT exiting exhaust system leading into a nicely tucked away expansion chamber.
It will offer a lower center of gravity compared to that of a Timber Sled.
No conventional motorcycle clutch in lieu of a CVT system. That alone will be excellent!
Larger fuel capacity as well.



If they pull this off, it's going to knock the socks off of the Timber Sled market.


Anyone have any updates on this?

Ok, it looks as though no one has any updates on this.

Question: If Arctic Cat did build this machine (in a 650cc single cylinder 2 stroke version), what would you think about it?

Id jump on one.
The possibility of a dedicated snow bike is the biggest thing keeping me from buying a kit now.

I keep going back and forth... 8 grand will get me a decent used snow bike or a sweet used powder sled.
Id love the boondocking, but so miss the horsepower if i went for the 450.

I am having a hard time understanding a 650 single cylinder 2s. That is a big piston even if it has a longer stroke and lower rpm. Maybe fueling and engine design has advanced enough for this to work? It does have my interest though.

Teth-Air, I agree..... having reverse would be excellent.

Boondocker, one of the advantages, in addition to a lower center of gravity, is lessor weight!

CB Rob, I fully agree. I'd buy one in a heart beat over that of a motorcycle conversion.
My son has a converted 450 KTM. The 450 just doesn't have the umff needed.
A 650 cc 2 stroke would offer the much needed power increase.

Old and Slow, that would be a large displacement for a single cylinder high RPM 2 stroke engine.
However, from what I see, the snow bike guys don't appear to power up as hard as we need to do in order to get into the same areas.

Lastly, think of how nice it would be to have the CVT instead of a spur gear transmission and clutch system.

I keep hearing people talk about how awful our CVT clutches are. That the gyro effect is too much to throw around .
Is there a math equation to put a weight resistance on a clutch spinning 8k rpm?
Ive never really noticed the resistance to movement or lack of.

I would probably try one if the price point was right. 10k or less and I think I’d have to.

Any time I’ve ridden with a snowbike they are constantly tinkering and having issues. They just aren’t built for the snow, and that makes it tough.

Doesn't the company that owns Polaris now own AC?

And that company also owns timbersled...

I bet we'll have to count on Yamaha or skidoo to make a snow bike that competes with the kits

Textron owns Cat. Polaris is its own entity. If I remember right, Polaris has also submitted patents for a dedicated snowbike with a CVT. I'll try to find the thread on that.

I would not be interested in a 4 stroke engine, nor the selective spur gear transmission that requres an In/Out clutch.

For me, the larger 650cc 2 stroke engine w/ the CVT is the answer.
The CVT has been used successfully for years.

If Bombardier is engineering something like that, I would be on-board.

I'll be bold here and will say:
Mark my words...... one company will evntually come out with a dedicated snow bike, a more powerful single cylinder 2 stroke engine, w/ a CVT, lower center of gravity, and it will blow the Timbersled out of the market!

While very fun to ride one, the idea of converting a dirt bike into a Timbersled is less than appealing.
It's like a dual sport...... it's not really a dirt bike, and it's not really a street bike.
