Cry Sore tailbone on street rides

In the last year or so my tailbone has become very sore after 30+ minute street rides. Ditto if I ride to work several days in a row (10min rides each way). I had a new seat put on a few years ago and it's medium density (Guts Racing foam & cover). It helps a little to sit so my tailbone isn't directly on the seat, but that gets uncomfortable after a while. I'm on a KTM 640 LC4.

I've never had problems with tailbone bruising before, and didn't have any accidents on or off the bike that could have affected my tailbone.

So I have a couple questions..

1) Anyone else have this problem?

2) Will soft foam break down quicker than medium density foam?

Coccydynia?

Is it sore / tender after you've been off the bike for a couple days?
Your age / weight? Maybe you need an x-ray, or at least an exam (depending on your age)?
Sometimes anti-inflammatory's or steroids will help, or a steroid injection. I would think a softer seat would help by taking pressure off the coccyx, but I know for myself softer seats get uncomfortable on long trips. I prefer a firm saddle, both for moto's and equines, but I don't have any pain in that area. A quality saddle should hold up whether it's softer or firmer.

I had this problem on a cruiser I owned once, I took the seat cover off, cut a hole/depression in the foam where my tailbone rested, re-covered the seat, problem solved by removing the pressure from the tailbone and all my weight was on my butt cheeks.

Try pooper Kegels. Clench everything down there tight and hold it as long as you can tolerate. Then rest and repeat. Just like if you were in prison. This would work on very very long rides for me. I would pass through a painful phase about 4 hours in and these helped.....the clenching part, not the prison part.

Stock BMW seat did this for me. Hurt to sit or stand up for days after a 1000 mile ride.
Corbin fixed me right up.

Try changing your angle of seating, not just the surface.

Although not the most elegant solution, an Airhawk will fix ya right up.

Yeah, usually feel it a day or so after. Mid 40s, F, tall for my weight (185).

How about if you didn't ride for a couple weeks, would it still be tender / sore then? Have you ridden a different bike? At age 45-ish, I would just try a different seat or pad for now, or modify the seat you have. Most likely you've just got some inflammation there and the current bike / seat / position just aggravates it (even if you're only riding once a week).

And you might wanna drop your 640 off for me to do a "full evaluation" LOL

slide your butt back and lean forward on the bars to take pressure off.

I've owned KTM duke II and 690smc. so I know what you mean.

the 690SMC is much worse.

you should be able to find KTM 'comfort' seat used.


even my stock ZRX seat wil do this but sliding back and leaning forward will work.

The Renazco seat seems like just the ticket.. plus it's taller than stock which is a nice bonus. Price?

This should fix you up....Corbins work for me - stiffer... too soft puts pressure on the tail bone...

Is that secret Butt Compartment I see on the back third of the seat? Looks trick but seems like it would be brutal on the budget.

I don't know the KTM's, does Seat Concepts make a kit for your bike?


http://seatconcepts.com/products#!/~...=0&sort=normal

If so, order a kit (I like the firm foam) and fashion your own butt compartment with a belt sander. Easy on the pocket book, too.

+1 on the Seat Cocepts foam, I have one on my DRZ and KLR. It must be some top secret NASA kit, very comfortable.
