Question Lower Back Crunch

Hello all,

First off - the Rebel has been awesome. My Dad rarely rides it but he may get on once in awhile after some persuasion, lol. Actually, I've been riding it and it's been a blast. Have about 500 miles and should be heading into the dealer for its first service.

Anyway, I wanted to ask if anyone else has experienced any kind of lower back "crunch" where you're going over a bump or railroad track and you kind of lift up and come back down? It feels like the lower back sustains some shock and absorbs the impact or pressure as a result. It's slightly painful, and I was just worrying since I don't want to mess up my lower back - it feels harsh when it happens. I've been riding consistently for about a year, and haven't encountered this on my prior CBR300R and current 600RR which I daily ride as well.

I guess I could try to raise up when the bumps on the roads or railroad track come, and I'm thinking this is what would be advised as well.

Still wanted to hear your thoughts...

Thank you in advance.

Welcome to the wonderful world of cruiser style motorcycles. You sit more upright and instead of spreading your weight to your thighs like a sportbike does, your butt takes all the shock.

Keep in mind the Rebel seat isn't all that great to begin with.

I see. I'm normally not a fan of cruiser style bikes, but the Rebel is fantastic since it has a great amount of nimbleness and athleticism to it.

Hopefully I don't end up with back issues, lol. I'll try to brace myself or prepare better when it happens. I like the seats, they don't feel too bad...

Are your shocks settings too high? Maybe lower the preload.

Have you adjusted the shocks on the rebel? If you look at the bottom of the shock you can see a graduated sliding part to adjust the shocks on the older generation 250. On the newer ones the adjuster is covered with a chrome piece with holes to adjust the shock.
You might need to adjust the shocks to make a softer ride.
Good luck

I rise up when I encounter an obstacle in the road.

I have no idea, but good point - will take a look at it to see if it's abnormal or out of spec.

I haven't touched the shocks since purchasing it new about a month ago - about 600 miles on the bike currently.

Will use your pointer and take a look.

I may have to form the same habit and do the same.

I have lower back issues myself. One way I found that helps ease the road noise that the Rebel seat directs to your lower back is installing a back rest and a seat cushion. You could even use gel packs for the seat, those will set ya back a pretty penny though.

When I took the MSF course, they told us to stand on pegs and lift butt up a couple of inches when a bump in the road is obvious. Alterntive is to lean shoulders way forward when going over the bump so as to lift tailbone off seat and lessen the shock.

Thank you for the continued feedback.

Leaning forward seems to be a good idea since I'm used to that on my sport bike.

I learned about lifting up on the pegs in my MSF class as well, although I'm fearful of losing my balance and would have to slow down greatly to be on the safer side.

It's not too big of an issue. A cruiser has a different ride, so I'm just going to have adapt and prepare better to the experiences.
