Faster to use hobby cutting disc. Cut perpendicular to race.

STEERING Bearing Replacement: How to remove the Outer-Race Bearing from the STEERING HOSE? What is the tighten moment for reinforced bearings(roller)?
It turns out that in our model Honda did not leave shoulders to extract the STEERING bearings by hitting them from behind (The bearing diameter is the same as the tube diameter).

Forgive me all the special tool manufacturers, I do not intend to own special tool for $ 300 to one-time job.
The leading idea at the moment is to cut the RACE rings by grinding stone.

Please! I would love to get more suggestions...<<< ? ? ?
Regarding the tightening torque for reinforced bearings (roller): In my experiments, a low value of 5Nm was obtained. The original ball bearings (OEM) need to be tightened to a final torque of 29Nm, a very significant gap. what do you think about it?
Un updating: I found a reference. John Tally tighten a roller bearings for the CRF450R steering. These bearings are a little more powerful and larger than what fits to the CBR250R. John ReTighten (The final tighten) to 5.2 foot-pound [ft*lbf] = 7.05Nm
[By the same ratio of 5 to 7 the First Tightening will be at CBR250R: 21Nm]

These are discs of dentists. These discs with "Dalmel" it is an excellent tool combination, cuts any metal no matter what the hardness.Faster to use hobby cutting disc. Cut perpendicular to race.

The problem is:
How to make the cut without harming the chassis?
Black color - The chassis.
Red color - The RACE bearing.
Green color - The dentists disk.
X-Brown color - An area we do not want to damage!!!
The diameters are the same, the inner step exists (See the revised diagram). A special tool does enter to this inner step but costs over 300USD. My experience with the grinding stone went on an idea similar to what you suggested, but I was unable to reach a complete detachment of the RACE (I stopped to not damage the chassis). At the end anyway I pushed from the bottom with a rod that I shapede so that it would grip the inner step, and then the bearing did break, and the bearing came out more easily. In the second bearing I used only the special tool I made.Or you can cut parallel to bearing race and make little channel. Then heat up outer head-tube with torch and pry off race with screwdriver.
