Brand new 450 L max problems

Hello people,
finally purchased a 450 l dps max.

Today i received the bike with 2-3 mins and 1 km on the clock.

Upon riding the bike for the first time i noticed that it had very limited power, even my last bike which was a 250 had more power.

It will not go past 50kms/hr - 32miles/hr and to get there it needs some time.

It revs up to 6-7k (not sure because i don't want to rev it up like this being brand new) in neutral with some hesitation and idles good but not perfect to around 1250 rpm but sometimes momentarily drops to about 1100 rpm.

Battery good, air filter good.


I'm from Europe if there is anything significant about that.

Is there any chance that the ecu is limiting things for the break in period?(which the manual does not mention at all).

Because if its not, somethings not right.

Monday morning i will call the dealer but until then id like to hear from you guys, thanks.

are you using the learner key?

I think both keys are the same on the new 450 L or am i mistaken?
That doesn't sound right. Even if it has a learner key it should have more power than that.

If it is not something related to the ecu (which i don't think so) i will ask for a replacement bike.

I just don't want a 8$ mechanic tinkering with a brand new bike, when it should have been a-ok from the get go.
Do you have a black key and a grey key?

#1 wrong key or #2 throttle limiter screw is in too far.

Thank you all for your replies.

Couple of things i noticed:

The two keys are the same just two standard cut keys, no dess system on this bike, however i tried them both with no luck.

Throttle limiter screw was in but removing it made no difference, the throttle lever will not go any further.
With the screw missing or unscrewed there is space, but the lever will not go any further (it seems to me that the lever has limited travel but maybe that's the way can-ams are, i don't know).

In neutral it will rev up to 8000 rpm albeit somewhat slowly.

On the road max speed is about 33 miles/hr at 5300 rpm, and it needs about 15 seconds to go from 15 to 33 miles/hr .
Today i called the dealer, and apparently the bike is limited by the ecu to 18% of its power for the break in period.

After i take it in for the first 10hr / 300kms service it will have full power.

Now i don't know if this is brp standard practice but i think the dealer should have mention it to me.
Plus there is nothing relevant in the manual.
Another question:

The gears are very hard to shift, especially moving between neutral and park and neutral to high. Its the same with the bike running or not.

I know can-ams are difficult to shift and i guess it will loosen up with time but if i do not rock the bike the lever will not move.

Could it be that it needs some sort of adjustment?
Sounds very weird to cut the power like that. My 450l was an animal right from the dealer. It got even more crazy after about 45 hours. Sounds like the can-am shake, most need to be rocked a little when shifting.

Shifter gets better w time and gear box oil change. Never heard of power being limited until after break in..

I also found it peculiar because i've never heard that before plus the manual does not mention it at all, which should be expected if it was brp standard practice.

Anyways ill do the break in and then we will see.

Thanks.
How about throttle cable way out of adjustment ? Somethin' isn't right...

Ok after riding the bike for a few miles i have some questions for you guys.(i havent done the 10hr service yet)

It will still go like a dog as mentioned before but only if its not warmed up.

After a few minutes of riding it will go better but still not as expected.

It will hit 40ish mph if there is enough road but even in downhill roads it will not go beyond 6150-6200 rpm, i guess that's the limiter the dealer was talking about (even though in low rpms the bike feels severely underpowered , i cant get it to spin the wheels on gravel).

So my first question is if there is supposed to be a difference in power output till the bike warms up, should i mention that to the dealer?.

Next question is about idle, it doesn't idle very good sounds like its missing.
It drops from 1250-1300 to 1100-1150 (sometimes even less) and then back up.
Is it supposed to stay at 1250 rpm, or is this idling pattern ok?

Thanks

My 500 was never limited from the dealer until after break in. I mean what if someone does their own servicing maybe the dealer did it just so you have to go back to them for servicing and you cant do it yourself.

Maybe, for now i trust the dealer that the bike is limited but in any case we will see next week.

Should i mention to the dealer the cold start power issue(is this normal?) and rough idle though?
Get a direct phone number to BRP customer service when you take it in to drop it off. Then mabee they will take your concerns seriously. Dont leave the dealer after the 10 hour service is done unless you have rode it around the dealers lot. Even if you have to go on the road to test ride after the work is done. Make sure the thing has full power or don't accept the bike!
One more thing, did you fill the gas tank or the dealer.......

Thanks i will do just that.

I filled the tank with shell 100 octane just to be sure.

Here is a video of it idling.
What do you guys think?
