Shown below are typical off the street, un-blueprinted, tired engines run up on my dyno.

The Yamaha TZR250R 3XV (-00 barrels), and Honda NSR250 MC21  have aftermarket pipes and ignition as in std form they are restricted.

The VJ22 RGV250 should have peaked at 55-56hp, unfortunately it's the best curve I have of an 'off the street bike', and unlike the others, the engine is in  pretty good health and not needing a rebuild like all the others.

As you can see the 3XV actually fares very well, having a strong torque curve with over 24ft/lb for over 2000rpm. Which makes it superb at coming out of corners, potentially good road bike, pity all we got was 38-40hp!  All the bikes have 56x50.6 bore and stroke except the NSR which is 54x54.
