Glad to hear you're ok, and congrats on your choice of riding apparel.
Reading over your previous thread you said that the problem was fixed. How many miles have you covered since the 'fix' and did it gradually return or did this just happen at the time of your accident? Was it the same symptom, wobble under deceleration, or was this something different?
As I posted in your earlier thread the only similar issue I've had on my R3T is a slight weave at speeds over 120 and never on deceleration. From everything else I've heard this is not a common problem and your initial problem sounded like a setup error, either by the dealer or the factory.
Good luck on your recovery.
