Greetings to all. I hope this helps to clear up confusion over engine power of CRF250L. Honda has tuned the CRF engine differently to that of the CBR so nothing wrong with dyno or tester. Apologies if previously posted - This from Honda Worldwide:

The CRF250L' s engine is based on a well-reputed liquid-cooled 250 cc single-cylinder DOHC engine, developed as a global engine transcending regions and known for being sporty yet eco-friendly while pointing the way to the next generation. The CRF250L version of this global engine aims for output characteristics that can be handled with ease both on and off road and deliver a fun ride. This new engine is designed to be lightweight and compact with smooth turnover, not just in the low- to mid-rpm ranges but also the high rpm range.

[/h]To give the rider easy control of the machine.even off road.while improving full traction performance, the development team pursued powerful torque with no "dip" in the low rpm range.
Furthermore, given the agile feel of a liquid-cooled DOHC engine, the model realizes the ideal response for an on/off-road model while maintaining a short stroke (bore-stroke ratio: .76 mm x 55 mm) in the base engine.
To realize output characteristics that are stress-free and smooth from low rpm to high, the CRF250L developers conducted a thorough analysis of the air intake/exhaust system, which allowed them to select the ideal dimensions for the intake/exhaust pipe diameter, pipe length, and throttle bore. Moreover, the quest for reduced air flow resistance led to an optimal shape and placement of the air cleaner element and its routes to the straight intake/exhaust ports and exhaust pipe.
To achieve a fun, easy-to-handle ride, an exclusively designed clutch transmits the machine' s powerful torque characteristics thoroughly and smoothly.
Exclusive designs are also added in other sections, including transmission with improved strength of gears to meet the demands of rough off-road riding.
The relief valve is set to control the pressure inside the oil passage, and an internal relief structure has been adopted inside the oil pump to prevent the aeration of relieved oil.
