Early dyno reports (850R)

[Doc Harley]

One little statement in that video on the subject of using XPS vs 'other' mixes. "Don't put other fluid in it (paraphrase)", "The algorithm is going to de-rate because the ECU is going to detect it". Its probably just the way he said it. The ECU is only aware of outcomes. It would not know the difference between heat as induced by ambient temperature and heat produced by an inadequate/improper mix. If the temperature isn't coming down, it will de-rate but if the mix is doing the same job as XPS then it will likely happily keep injecting it. Let the XPS replacement snake oil wars begin..

As to longevity. I don't think there will be a lot of issues, or at least a lot more issues than there are in any 2-stroke. Is it likely that buyers of this sled are going to beat it to death.. some will for sure but there are a lot of (for instance) corvettes being driven around by people who have never found the floorboard with their right foot. Those guys that are are already beating their sleds up will treat this sled the same way and for them, rebuilds=bragging rights or at least war stories. For the average guy it will likely last as long as a normal 2-stroke which is somewhere between 0 and 15k miles meaning not a huge amount of difference. They (doos) are getting better based on anecdotal evidence as you are starting to see more recent model high mileage 2-strokes for sale whereas there used to be a practice of trying to kill the motor for warranty replacement before resell. A friend who is an occasional rider and likes 2-strokes is trying to buy a used one right now and all we see in the bargain bin is 10-18k Kms sleds (no thank you).

The comment about the model being a novelty is a cultural/language thing. When the Quebecers reference something as being a novelty it is more of a positive statement than the way a US english speaker would use that term (cheap or gimmicky).

The one thing you can probably say is that the ceiling is likely low as far as power upgrades go. A moderately upgraded (300+) winder is still going to be a very reliable machine. An 850 comp with 50% more horsepower than factory is not.

Spot on as expected, earthling

Really cool tech on this one. I like that it's controlled by IAC's vs boost referenced.

 

[Doc Harley]

Another video, definitely clearance issues. They're installing studs 1.34" hmmm

 

[NYTurbo]

They could of easily gone up another size stud

I'm sure they were being safe. I'm also pretty sure they won't be installing the 1.86s
All in all....it will be a tough competitor in the hands of the right tuner.

They have clearance in front for now. We will see how suspension and ballooning of track effect that

 

[NYTurbo]

No different than any sled. 1.575 on Winder will do damage things aren’t kept tight.

We can run 1.86 on a 1.25 they are down to 1/8” maybe little more with 1.5 studs while on the stand

 

[NYTurbo]

yes because they have 5/8 tunnel protectors. Winder has good clearance but the big issue is always at the drive to tunnel with most sleds . Doo doesn’t have the clearance a wonder has at least the 900Rs don’t.

They went to a 9 tooth driver instead of a 8 tooth driver.

Isn't a lot of that due to hard braking & the track trying to come around on the driver?

 

[NYTurbo]

Should have one in the shop tomorrow or Monday, will have a close look

All stems from improper the track tension

Could this be why brp chose to use the 2ply ripsaw2? Im betting yes. No ballooning.

Um, they all balloon, a 2 ply will handle studs much better though.
