Have you consider just having your stock seat redone?? Here what spencer motors sent me in an email on what he does to a stock seat. I thought about it.
For your stock Vulcan 2012 900 Classic LT seat the usual modifications to the rider area are the creation of an actual seating pocket so that you sit more in the seat rather than on it, softening of the frontal midline to take pressure off of the crotch, along with correcting the too quick of a "turn up" at the rear of the seat to take pressure off of the tailbone and allow the back of the seat to actually give some support. If you add the Supracor suspension included in the LD upgrade it will allow a more form fitting and weight distributing shape, reduced vibration in the seat, and dampening of road shock. These changes help to distribute your weight across the seat rather than concentrating it in the center which allows more contact to help stop the pressure points. The Supracor works for the rider because it is a dynamic material with an instant rebound. It moves with you, working with your weight shifts for proper bike control. If you use a material in the riders section that "takes a set" it locks you in one position and fights against you. This is the main problem with foams as the rider is constantly moving, even while cruising the highway you are making small corrections in your weight distribution. You can find more information about the material HERE.
If needed the passenger area modification is similar but on a smaller scale. It concentrates on them needing a position that keeps their weight stable, and because of them having less contact points with the bike, a position that gives them more confidence and control over their position during braking and in turns.
Pricing would be the standard minimum of $50 for the actual work to the riders section, a $25 material charge for the Supracor, and $15 for the passenger section when done together but again only if needed, it doesn't effect the rider either way. Your original seat cover will be re-installed after my work is complete.
All of my work is done within the stock foam form, creating a new internal shape and supporting structure. The exterior appearance and dimensions of the seat are unchanged at rest so the stock seat cover stitching and studs will all still line up correctly. You will absolutely know that major changes have taken place when you ride.
A photo of you on the bike is helpful and appreciated, but not an absolute necessity. Each seat is set up specifically for the rider so any additional information you think I may need regarding your position, type of riding, any medical concerns you may have should be listed in the special instructions area on the order form. When you think you have given me too much information, just a little more should be about right.
Please feel free to ship at your convenience, all that I ask is that you drop me note when you do so that I can properly set my schedule. My current turnaround is no more than 48 hours so your only real downtime will be in shipping. If you visit my web site you can find the Order Form as well as my FAQ page which contains more information regarding shipping, payment, and a bunch (probably too much) general information. Contact me any time if you have questions.
Thanks again and ride safe, Spencer
