THIS picture from a Thai forum (thaispyshot.com) seems to suggest Honda is set to launch a 300cc version of the CBR250R in September this year.
The bike looks identical to the 250, so presumably the changes are to the engine alone – perhaps as a worldwide model in response to Kawasaki’s Ninja 300 or simply a regional variation on the existing machine. In some places, for instance the bike we know as the CBR125R is sold with an extra 25cc as the CBR150R.
The picture seems to come from a Powerpoint presentation, presumably some sort of dealer presentation of new models. We’re not even certain which language the text on the picture is in, but if you can translate it, do let us know…
Update 7/5/2013: Thanks to Visordown member thoppa, we now know the following: Electronic ignition, single cylinder, 4 valve, water cooled, single disc. 143kg, release September 2013.
