Here's the problem with the Versys-X 300 for me:

It's got great top-end performance that is obviously coming from a big cam. That means poor fuel mileage and poor low RPM performance as dynamic compression suffers for good high RPM horsepower. You're better off getting a 500cc bike with a smaller cam and better low-end torque. It's more efficient. Like the old saying goes, "there's no replacement for displacement". I prefer Honda's single in the CRF Rally that gives better low-end torque with less top-end. The benefits in fuel mileage are about 20% over the Versys 300. Suffice to say however, that the Versys-X is a very practically styled bike for an everyday commuter who wants weekend fun camping off dirt roads way up north. But the fuel mileage trade-off is not for me.
If you wring the rally's neck (redline 10,500) the lack of top end isn't an issue,but fuel mileage suffers.Riding wfo gives me about 75mpg.Riding it like a 65 year old gives me 95mpg easily.When i bought it ,i was really dissapointed with the lack of comfort.But putting the corbin on has made it as tourable as anything i have ever owned...almost.Not worried about riding it all day at 7,000 rpm,it's a Honda.
