Really enjoyed the day on the G450X, some things to work on but off the floor a good ride. Will be considering it when it is time for me to change bikes again.
If you want any info on it have a look at
http://www.motorcycles.bmw.com.au/indexframe.asp?PageID=30785Some servicing by BMW to keep warranty is required, but oil changes etc you can still do yourself. From all accounts though the servicing cost is reasonable and owning the bike is on par with the main runners in the 450 class.
They also have a growing aftermarket supply, including long range fuel tanks and bashplate/rad guard.
Will be interesting to see how I ride when I jump back on my own wr450.
