US V4R restricted?

Here we go again! Refer to the OP. Nothing to do with power, more power and what you can and can't handle.

The post was about is the R restricted, which it seems to be, and how. Not only that but did anyone know if the up map was/was not used, can the R achieve more than shown on the dyno run etc.
 
It's not restricted. The S claims 226 with the full akra. When that's run in it will gain a few and should be in the region the claimed engine power difference. I think the problem is people looking at too many happy high reading dynos

Here's the deal. Check out this link on the US EPA site, row 78, it's the V4R. Says 153kW at 13,250 rpm. The regular V4 is 158kW at 12500.

https://www.epa.gov/sites/production/files/2019-02/on-hwymc-2006-present.xlsx

Ducati's site says the V4R without the Akra should be 162kW at 15,250. So it looks like the US bikes are restricted in stock form to the tune of ~12hp and ~2,000 rpm. Hopefully the up-map removes the restriction.

By the way, for the regular V4/V4S, the EPA data is almost exactly the same as Ducati's published figures (without Akra).

Yeah, that's more the kind of answer I was looking for, cheers :)

so in order to get the acclaimed HP from the stock V4R is to buy the Akra and get 'hope' the up-map included gives you the normal stock HP AND the acclaimed HP you are hoping to get with the exhaust (234HP)... interesting

Exactly. Hoping to talk to my dealer today and get some definitive answers.
 
Im sure 650 will keep us posted via his youtube channel on his upgrades/alterations to his new V4R.

His dyno runs at Ducati Detroits dyno show on his old 1199 178hp/89 ft/lbs,and on his V4 speciale he got 199hp/85 ft/lbs.

It will be interesting to see once he gets his new BMW S1000 what it will do,on Ducati Detroits dyno as well.
 
The V4R in stock version is restricted to 209Hp in US & Canada because of noise restrictions.
However if the Akra system is installed it goes up to the 234hp just like Europe. But that wouldn't be street legal. Mine won't see much public road anyway.

From my dealer.

Seems as though if the revs are limited then its electronically

It also seems like the US version of the V4R page is also very reluctant to quote standard performance figures!! They don't quote the power figure without a side note saying (with Akrapovic Exhaust)

UK:
Panigale V4 R
POWER
221 hp (162 kW)i
TORQUE
112 Nm (83 lb-ft)i
DRY WEIGHT
172 kg (379 lb)

And also shows a graphic switching between the standard and 'race' values.

US:
Panigale V4 R
PRICE
$40,000i
POWER
234 hp (with Akrapovic Exhaust)i
TORQUE
112 Nm (83 lb-ft)i

The US graphic shows 'race' values only.

So do we know where the V4R tops out at in terms of MPH, last Panigale R was 202mph claimed Ducati, I haven't seen gps though.

guy needs to learn to ride first. More HP is not what he needs.
 
So limited answers from my dealer at this point. What does seem to be confirmed is there is an electronic (ECU) restriction. Best guess at this point is it is similar to what happens on some of the Japanese sportbikes where the throttle butterflies don't fully open in the higher rev range.

The reason manufacturers do this is to lower the rpm at which peak power is produced. The reason they lower the RPM at which peak power is produced is to enable it to pass sound level regulations; the EPA measures the sound levels produced at 50% of peak power rpm. With the V4R power normally peaking at 15k rpm's, sounds like it couldn't pass the sound level regulations.

The Akra up-map is supposed unlock all of this. It doesn't seem like you can get the up-map without also purchasing an Akra. At this point, not aware of any other options for the V4R. Bren tuning currently doing some beta testing on the V4/V4S ECU; not sure if they are also working on the V4R.

Thats a real kick in the nuts for those who wanted to buy the V4R mainly for the road and keep it legal. It'll have less power than the V4S according to the EPA data.

If it is mainly for the road, I guess it has enough power:D
You have to be insane to use full power constantly on the road

You're missing the point. Saying the power isnt enough.. Of course it is! But if you're being sold something and you get something substantially different... I'd still be annoyed.

Ducati's flagship R is less powerful than the mid range S in stock form.
