Welcome to a near neighbour. Only a few from Malaysia have signed up here, from KL and Penang as I recall. Where are you from?
The CBR250R has been around for only about a year and a half, with only a few getting up around the 30,000 km mark. There seem to be no serious issues to date (with Thai made bikes, at least), as we have come to expect of Honda. The odd concern expressed on this forum has come to nought.
