Just got new motor for Cbr 1000rr

What oil do I use on new motor. From break in and as mileage progresses

Break-in & Break Mean Effective Pressure (summarized)
B.M.E.P is an important part of the break in process. When the engine is running, B.M.E.P. is present in the cylinder behind the piston rings and its force pushes the piston ring outward against the coarse honed cylinder wall. Piston rings are designed to take advantage of the pressure and us it to push the rings out against the cylinder wall. Therefore, as pressure builds during the compression stroke, the rings are pushed harder against the cylinder wall which aids in seating the rings.

The higher the B.M.E.P, the harder the piston ring is pushed against the wall. The surface temperature at the piston ring face and cylinder wall interface will be greater with high B.M.E.P. than with low B.M.E.P. This is because we are pushing the ring harder against the rough cylinder wall surface causing high amounts of friction and thus heat. The primary deterrent of break in is this heat. Allowing too much heat to build up at the ring to cylinder wall interface will cause the lubricating oil that is present to break down and glaze the cylinder wall surface. This glaze will prevent any further seating of the piston rings. If glazing is allowed to happen, break in will never occur. Also, if too little pressure (throttle) is used during the break-in period glazing will also occur. Norton Owners Association.

I break-in motors as prescribed by the mfgr AND I properly warm all my vehicle engines before placing high loads on them.

As for oil during break-in, conventional for several changes.  Once the engine exhibits the power characteristics you like, feels strong and isn't getting stronger, switch to full synthetic.

 He's not talking about a British twin built in 1972.    

A new Japanese motor is a marvel of modern engineering.  The materials, processes and tolerances used in manufacture make break in less important than it used to be.  Just follow the manufacturers recommended break in procedure for that motor.  If you really wanted to do it right, use a break in specific oil with high zinc, low detergent and no friction modifiers.  But any conventional oil should be fine.
