Would you all prefer that they release a bug-ridden, destined-to-be-recalled, beta version of the bike?
Again, the G310R is just now beginning to trickle out to dealers, after BMW had more trouble working out the manufacturing kinks than they apparently expected. There have been zero reports of any buyers anywhere getting their hands on one before just a couple of months ago. And it's being built in a single factory in Hosur, with BMW quality control guys inspecting each one that comes off the assembly line. Any bike that doesn't meet their specs gets crushed. And being a new design, from a new factory, you can be sure that more than a few of them have ended up on the scrap heap. Personally, I'd much prefer that other people beta-test the design before I get the chance to hand over my hard-earned cash.
This isn't a Foxconn operation, with millions of units rolling off the factory floor. So BMW is going to do the smart thing and target those few available units to places where they can expect them to have the most positive sales impact. And that means places other than the U.S. Because most of us here are besotted with size and horsepower, and the G310 is most likely to sell here in very, very small numbers. Frankly, I'm astounded (and pleased) that they even have plans to sell them here.
There have been rumors that BMW plans to release the R and GS versions simultaneously here in the U.S. So there may not be a delay for the GS this fall (which is when it was always intended to be released).
In any case, I live in Oregon, and if I don't ride in crappy weather, I don't ride at all. So even if it finally comes out in mid-winter, I'll still get out there and break in the engine and get the bike ready for spring and summer touring. We have a saying here: There is no bad weather, only bad clothes.
