"Lightly" rear-ended

ericrobinson · Aug 11, 2017

Hey team,

I got lightly rear ended after I came to a quick stop, to avoid a left turning car coming the opposite direction.

I had come to a full stop, with some ABS engagement before getting hit. I think I was pushed forward a couple feet, back wheel locked up due to contact with the bumper behind me. Front, I'm not sure about.

Aside from whiplash and a trip to the emergency to be checked out, I'm sore but OK.

The bike appears fine, contact was my back wheel to the bumper behind.

Where should I look for possible damage? I had a good look at the swingarm, no obvious crack. Wheel spins true. Appears to be a touch of brake fluid leaked from the front brake reservoir.

Any tips or suggestions for ensuring bike it OK?

Bearing damage comes to mind. Only one way to check that.

Otherwise, not much different than any sort of riding abuse found on crap roads and potholes.

Brake fluid leaking from the reservoir is likely unrelated, but should be addressed. Mine (2015 hypermotard) had the same issue which in my case was just that the top cap wasn't screwed on tight enough. While unlikely, I'd have the frame and forks checked to ensure they are still straight.

There are a lot of things that could be bent, broken or cracked and you would never be able to tell by looking at it. Heck it may even ride just fine but something could be out of whack now and over time could cause you serious issues down the road. Take it to a professional who can check it over properly and make sure nothing is damaged. At the very least you need to make sure your frame/swingarm/forks/triples/rear shock & mounts are all still good and straight/undamaged. I may be overly cautious but that's what I would do.

I'm going to second this comment.

On another bike, many years ago, I had a light rear-end collision, lighter than what you described, and found key damage to a frame joint near the swingarm attachment point only by removing the swingarm and inspecting closely. Failure of that joint would have been troublesome, at best.
