Honda announced the new 2019 CRF250F in early November, 2018. Details on the Honda CRF250F web page.
Features and Benefits
Let's have a look at this new beauty...
The Brazilian home model has a headlight, and a small instrument panel hidden behind it.
ThumperTalk inmate 'tatau' from Brazil posted a very informative video on ThumperTalk where he showed the 250F completely disassembled. He showed the cylinder head and cam and discussed various features. CRF250F how its made
Some of his comments:
"Rear shock is locked like in the 230. I had to drill it to remove nitro and then disassemble it. But the internal valve and shims stack is much better than 230."
"Head gasket is multiple layered steel."
"Dog bone not aluminum, only the swingarm is."
"250F steel chassis is 5.3 lbs heavier than 230 chassis.
250F engine is 6.6 lbs heavier than 230 engine.
I was surprised to find out 250F steel gas tank (without gas pump) is 1.1 lighter than 230 plastic tank."
