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.

https://www.epa.gov/sites/production...6-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.

https://www.ducati.com/us/en/bikes/p.../panigale-v4-r

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

Looks like the V4R is more dangerous then bump stock, at least in the US.
Thanks from Danger Close MFG

It will be interesting to see once he gets his new BMW S1000 what it will do,on Ducati Detroits dyno as well.
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
You have to be insane to use full power constantly on the road
