Alert - CBR300R news October 18, 2013:
Further info here: Research
Over the winter of 2011/2012, word leaked out that Honda was going to release a new 250cc dual sport moto called the CRF250L. This lead to all sorts of speculation about what engine would be used (CRF250X/R) and how great it would be with CRF suspension, etc. Eventually Honda showed the CRF250L at the Tokyo show in December 2011. And then pictures (and videos) began popping up all over the place.
I began collecting pictures, links, and info and have gone through it all and unashamedly put it all on my own web page. I have noted the source of what is presented, when known.
The goal of this web page is to collect a lot of the info into one place and then to document my eventual purchase, modifications, and riding of this moto.
June 29, 2012 ALERT - Skyler Long of Timme Motor Sales in Pueblo West today confirmed that he has ordered CRF250L motos and the first one is on hold for me. Delivery is expected in August/September.
August 1, 2012 ALERT - Skyler advised me that the CRF250L will ship from the warehouse (Long Beach?) on August 17, so I may be riding by Aug 24!
August 15 - Surprise! Look what Santa brought.
"So, Rick, make sure the kickstand is down when you park the bike...."
It's a perfect fit and exactly the color I wanted. Gonna have to buy all new gear to match.
Happy days are here again.
Here are pictures I found on several Honda web sites.
Honda showed this version of the CRFL at the Tokyo show. This model is not expected to be built and sold by Honda; it was a marketing/engineering exercise to show what could be done to the base CRFL.
Here is a Supermoto version shown at the 2012 33rd Bangkok International Motorshow.

The crank journal employs a half-split, press fit metal bearing for the first time in a Honda motorcycle for the single-cylinder off-road category, while the crank bearing uses a cast-iron bush. To reduce weight and improve quietness, the design strengthens the rigidity of the case housing and controls the change in internal diameter oil clearance from thermal expansion. In addition, vibration is reduced by adopting a primary balancer.
To reduce the friction of the piston's reciprocating portion, the CRF250L employs an offset cylinder (offset 4 mm to the exhaust side), and the piston incorporates thick streaks and molybdenum coating, which facilitate lubrication by engine oil.
To reduce blow-by gas and oil consumption, a spiny sleeve was adopted for the cylinder sleeve. Small spines have been added to the outer surface to improve cooling performance and help reduce distortion of the inner cylinder's shape. In addition, centrifugal casting allowed a thin, uniform wall thickness, which aids weight reduction.
To fulfill basic performance requirements as an on/off-road model while setting higher targets for environmental performance, the development team came up with a roller rocker arm design for the valve system.
The extremely compact layout allows a low-fiction valve system to be achieved with a small cylinder head.
Part number 5 is the pickle-fork rocker arm. Part number 6 is the rocker arm pivot shaft. Not shown as a separate part is the internal roller which rides on the cam; see panel above.
Valve stems have been made thinner, although valve diameters are large for both intake and exhaust. This valve design is coupled with a wide opening angle and a high-lift cam to improve intake/exhaust efficiency. The valves are made of stainless steel.
Air induction and O2 sensor locations.
The air induction tube is inside the otherwise empty area of the cylinder head.

CRF Mods and Improvements
* Drill another set of holes in the lower shock mount
* Lower the triple clamps
That's about the easiest I've ever seen it done.
And it's easily reversed.
