I picked up a used Corbin for the Uly (thanks Keyser_soze). Got to do my first decent length ride yesterday and I Like it.. The stock seat put pressure on the bones in my Arse and killed me after about 70 miles. Picked up a low seat and added a lambs wool pad and it was better but almost too low for me and was HOT! even after adding Odie's heat shield it was HOT!. The corbin is wider at the back and narrow enough at the front to still get the balls of my feet on the ground. taller than the low seat so it raised me back into clean air. Just wish it had Orange leather on the passenger area... The extra black has noticably slowed the bike  Maybe this winter it will go back to Corbin for a change.. The low seat should be nice in the winter - heated with no electrical mods. MB | ||

Glad the seat is working out for you. The bike just feels slower because you are coddled in pure comfort. We all know that the black bikes like mine put out 10-20 hp more than orange  KS | ||

Mb182, How is the Corbin passenger part? My wife says the stock seat needs more padding and the seams are killing me. Can you comment on the passenger part? Thanks, Joel | ||

MB, Did you arse go numb also? It seems like 70 miles is the magic number. Did the low seat/wool setup cure the problem also or just delay it a little bit longer? Its nice to hear I'm not the only one thats has this problem. | ||

If you guys want to analyze the numb butt issue a little, here is what I learned when I had the same issue with the stock seat on my M2. The numbing/pain results from your buttocks being pressed together and putting pressure on nerves or nerve bundles. It generally results from the foam in a seat being too soft. The normal concentration of your weight depresses the foam the most in the center of the seat, at the same time the foam on the sides of the seat presses inward and upwards. The pressures focus upwards and towards the center of the seating area and the part of you that is in contact there. And that was where the part of me that was in pain. The pain showed up quickly, was bad in 45 minutes to an hour, and dangerously distracting in 90-120 minutes. I tested a possible solution by getting a piece of 1/2" thick high density foam (it has much less give to a finger press). I cut it to fit the main weight bearing area of the seat. I held the foam in place temporarily with a "tube" cut from an old tee shirt around the seat and taped across the bottom. I rode away from home for 45 minutes. The relief was soon obvious. At 45 minutes out I was feeling some pain but it was much less. At the 90 minute mark, when I returned home, I had some pain but not anywhere near what I felt before. I repeated the experiment with a second piece of the high density foam under the first piece. The 2nd piece was about 2/3rd's of the seat width and added some additional firmness in the center. Some increase in seating height came with the experiments but I was okay with that, I even liked it better that way. For the record, I'm about 6'1" and 220 pounds. The test helped me decide I needed a firmer seat and that higher was also okay. I found a used Corbin on eBay that was firmer and also a little wider and it turned out to be wonderful. It did not look quite as sleek when the bike was setting unoccupied but I loved the comfort. I only rode solo but the passenger area on that seat looked to be more comfortable too. I'm not necessarily endorsing Corbin seats as a universal solution but if you look at seats, consider or ask about factors like the density of the foam and firmness compared to your stock seat. And seat width and height can also be a factor for some of us. Jack | ||

ChrisB, Not numb - just pain! The seat put all the pressure right on the end of Arse bones where the hips meet the pelvis.. VERY uncomfortable! I don't know if too soft or not wide enough was the problem.. The low seat with the lambs wool was very comfortable, Hot, but comfortable. It sat me a little lower than I liked, but the heat was my reason for trying the Corbin. I need to get some more Velcro so I can add my Lambswool to it before I ride to far. MB | ||

I have to agree with MB about pain not numbness. If I rode longer it might turn into numbness though. My soreness starts in two places but at about the same time intervals. On my lower/inner leg where the seams run accross start hurting and making me spread my legs like it is too wide at the same time the two Arse bones start hurting. To me it feels too hard at that point like I've been sitting on a plywood seat. Possibly it is because the padding is too soft and has compressed. I have to say though that the stock seat never feels soft at all to me. It always feels very firm to sit on. I think it is great for my short ride back and forth to work, but time wise 20-30 minutes of continuous sitting is when the pain starts. I do know for sure that the width just back of the nose of the seat is too wide for me. That is where it bothers my legs and I notice myself trying to spread my legs to get around it better. For reference, I am 6 ft tall and about 175lbs. |
