Common parts on 06daytona 955&06st1050

I have both a 06 D955 motor and a 06 Speedtriple 1050 motor,I am pondering using a 1050 crankshaft and upper case half with D955 rods,pistons,cams and camchain along with D955 exhaust header and ecm,I plan on installing this in a 06D955 frame,I've heard the case's are compatable but am unsure if rod jounals are the same diameter,does anyone out there know for sure?I do plan on matching the cam chains up for comparision and claying the piston to valve to make sure the Daytona cams aren't making to much lift.This seems like a quick way to increase displacement and power as both motors make maxim h.p. and trq. at 10700rpm,if the afore mentioned rpm isn't exceeded the 1050 crank should hold up ..right?Any thought's welcomed.Alloymotor.

The respective big-end & crankshaft journals are same nominal sizes
However max power on the 1050 is at 9100 rpm NOT 10,700 as is the Daytona 955
Asking a lot for that longer stroke crank to run to 10,700 - the piston speed on the 1050 crank is going to be about 10% higher than the Daytona crank at any given rpm.
The Daytona crank is also much stronger and the cylinders are nikasil vs cast in the 1050.
The parts will fit but don't think there is any way you can run it past the 1050 redline and without that, not a lot of point.

Thank you very much for your quick reply Decosse,guesse the info I found on max rpm for the 1050 was erroneous,just out of curiousity what do your sources say?I was planing on lightning the the crank and increasing the oil oriface diameter somewhat to compensate to the afore mentioned short comings along with magnafluxing and polishing for possible stress fractures,seldom do I exceed 11000 rpm with my 03 D 955 and would hold to 10500 rpm on this project motor.Allloymotor.

Allloymotor, As an exercise it's certainly doable. Lighten the crankshaft, chamfer the oil holes in the crankshaft, shot peen and resize the rods and porting the head will deliver performance. AFIK there are no aftermarket camshafts available to take full advantage of the additional displacement. The unanswered reliability question will be "For how long?". Let us know how it goes!

Piston speed on 1050 stroke at 10,500 would be equivalent to that of the 955 at ~ 11,600 rpm
