Thor GS Easy on the V20

Ever since I got my Vendetta in August I've been fighting with the stock seat. Different padding, several custom headrests, and building up the back with a foam wedge. The stock configuration was completely unworkable, especially the neck rest, and my various mods only made it tolerable.
I finally had the opportunity to get a Thor seat this week. I'm not in a financial position to just apply money to problems, otherwise I would have done this from the start. I was offered a very good deal on a 'glass GS Easy by Jonathan and @Robert Holler at Rose City. It was one That the shop had used for testing purposes.
It arrived on Wednesday and was installed by lunchtime on Thursday. Custom work consisted of building a chock to go between the frame and the back of the seat and trimming down the sides at the very top so that my Bacchetta Brainbox would fit. I also built a neck rest from flat aluminium stock and a backing plate that I had from a previous project and a seat pad made from a camping mat.
The result is a revelation! The seat is about one thousand percent more comfortable and supportive than stock. On sprint efforts I can dig in with the hips as well as pulling on the bars. It makes me and the bike feel like one unit.
The Easy has more of a lip at the front, which I like. The angle is in the mid to high twenties, so probably not as absolutely aero as laying on the CF ironing board, but I'm willing to trade those couple watts for all the benefits. I put a rubber washer under the front bolts and the rear mount has vibration damping qualities, so the ride on bad pavement (most of it around here) is greatly improved.

That's great. I think you are the first one who has the Easy model on V20. Happy to hear it works well!

Hey M.J., what type of material did you use to make the chock between the frame and the seat and what dimensions?

I used a piece of high density foam shaped to fit, soaked in epoxy, and wrapped in duct tape
Duct tape + epoxy = carbon fiber, right?
This high tech part has Velcro on both sides so it is stuck to the frame and the seat is stuck to it.
The whole works is secured with a couple zip ties through the seat and around the frame.
I'm a bit of a hillbilly...
It's holding up great so far! The chock is triangular, so if I move it forward the seat angle increases, back and the angle lowers.

Without doubt mj comfort is speed. Well done on finding your solution. And a good deal too. Love a bargain :)

The stock neckrest is part of the extremely stiff efficient frameset. Unfortunately that transfers a lot of road chatter through to the noggin. Seemingly we all have variable tolerance and body shape with most achieving comfort in stock equipment.
For me it was a simple inflated inner tube shaped that gave me nirvana. My vendetta is very comfy with 25 mm tyres at 90 psi with inflated neckrest.

ive ridden cf railgun seats bachetta and others. It really is very personal individual comfort.

Congratulations on finding your solution. Now go show and carve those roads up.

To "fill in the gaps" between the frame and seat, I used (and others here too I believe), malleable (moldable) plastic that I got off of Amazon.
Costs about $10 and works great.

Totally late to the party....

I have my new thor seat and have the same problem - I have the brainbox, but it won't fit over the seat. What did you use to cut yours down?

Same as you, the stock seat simply hasn't worked, and so I applied money to the problem. Even unmounted, the new seat is WAY more comfortable (I also have an Ice VTX trike which has a very similar seat, and I can sit in that thing all day).

Thanks!
