Can the rear shock jam on a new Hawk?
New 2017 bike. I'm 240lbs, when I sit on the bike the rear shock compresses about 3 inches and then thud! Feels like it hits something. I look under and the spring isn't compressed all the way it just stops. I can't find any posts discussing this. Can I take the shock apart? Should I try?

I don't think this shock is serviceable. If it sounds like it is collapsing, better off see if you can find one of the same length on e-bay with the same dimensions on the bolts.

The rear shock isn't serviceable as far as I am aware, but it definitely shouldn't stop like that. I weigh a bit more than you do and have ridden my bike pretty hard over some whoops and the worst I have done was hit the bump stop lightly. I can also hop up and down on the bike and not bottom out the shock.
I can only think of 3 things that might cause this. 1. Something in one of the coil gaps - but you should notice that. 2. A larger than normal bump stop on the shock shaft or some other manufacturing defect. 3. The shock body is hitting somewhere on the frame due to being installed incorrectly. The spring should be on the bottom, closest to the swing arm. It's a good idea to put a bit of marine grease on the shanks of the shock mounting bolts as well since the shock does pivot around them. If you can't figure out what is wrong and you haven't had the bike very long, consider contacting the store you purchased it through about a warranty claim on the rear shock.

Dadbeck, I would try to take the shock out and put it in a press, if you have access to one. Maybe a nearby auto shop will be friendly enough for you to have a look. My thought is that the shock you have installed on your more recently manufactured bike has internal parts that are preventing the shock from making what we would consider a full stroke. So while the shock looks similar from the outside, the internals are designed to not have the same range of movement. This is usually done as a result of the pointy-headed bean counters discovering that if they shorten the travel of the internals, it takes less material to make to the shock, and that means more shocks from the same amount of raw materials. If I remember correctly, one of the big 3 auto makers here in the states had a pretty rough patch (no pun intended) after they did that and people got so frustrated with the poor ride quality of the cars they were putting out. What's worse, is that after people got wise to what was going on and replaced the rinky-dink shocks, the suspension geometry didn't work anymore and the ride actually GOT WORSE! In any event, I would say the best bet would be to take the shock off and see if it travels the full range out of the bike, and that will narrow down where to start looking. Also, when the shock is off, it will be much easier to pivot the swingarm and see if something is jamming up on that end of things.

Thanks for the feedback.
I'll inspect it more closely and remove it if I don't see anything. I got to ride it last night and really enjoyed it. Watching others ride on youtube doesn't prepare you for how light the font is. The hawk can turn on a dime!

Well I took it off, no grease on it. I bought the bike assembled. I greased top and bottom bolts, I also used marvel mystery oil on the shaft. While I had the bike up I trued the rim. It really helped. I don't notice a hard stop anymore. I'll have to take it off road to test it out.

Maybe, I still think the rear travel isn't as long as it should be. Did some logging roads tonight and it seemed just "ok". I need to find someone local who has one, they could tell me what's normal. I'm really impressed with it so far for the 1100.00 I got it for. Not counting plates and tags.

Most of the people on this forum have said something almost identical to that once the bike was uncrated and assembled, or after they had their first ride on a bike they bought used. Really glad it's working out for you, and that you're overall happier with it now than you were a few days ago. Happy riding!

You have to keep in mind that these aren't exactly motocross bikes. Their suspension travel is greater than that of most road going bikes, but shorter than that of most true off-road style bikes.
