The owner at my local dealership said they got one shot at ordering for the whole year. After that, it's wait until next year....If it's anything like the release of the new-gen Ninja 250R or CBR250R, dealers will only get a couple of R3s to gauge interest initially.
Once they finally know what we know, that it will be a huge hit like those other two, they'll order a lot more that will be showing up mid to late summer.
These new small bikes are always rare as hen's teeth the first couple of months after release.
