Renazco Custom Made Seat

I had originally planned on heading down to Corbin seats in Hollister, CA about an hour and a half drive from my home. They make custom seats, but primarily focus on street motorcycles. So after researching on the web I came across Renazco Racing Seats located in Santa Rosa, CA. James, the owner has done quite a few off road and dual sport seats. So I sent him an email and didn’t expect to hear back for quite some time. Having read forum information about his seats, lead times were around 6-8 weeks. Plus it was Christmas time….

To my surprise I heard from him in two days and this was during the Holidays! He mentioned that he was intrigued by ebikes and would be more than willing to build me a custom seat. So I sent him my stock seat and in two days he wrote back to me that he had stripped the upholstery and foam from the seat. He mentioned that the seat pan was of a higher quality than most he sees and the foam was rather hard. He had questions like my inseam length, my weight and if I wanted any color of stitching. I had sent the stock seat to him with blue tape where my ass resides when I ride, which is the back quarter of the stock seat. I also had sent him photos of me sitting on the bike so he could get an idea of my posture while riding.

This makes it very apparent how much more padding and shaping the Renazco seat is than stock. In addition to the foam he uses, no hard edges makes a big difference.
Stock X seat. See the slope and hard edges!
Renazco seat, what a difference!

He wanted to cover the entire seat in suede, but I asked if the sides could be ‘carbon fiber’ and he told me he had just the color grey to match my bike. Suede is the favorite cover for his work since it breathes and grips as well. I also asked that the slope of the stock seat be taken out since it causes me to slide forward when I don’t want to do so. Taking out the slope combined with the suede would make the seat a whole new animal.

I had written to ask if he would mind sending me some photos as he progressed. But the very next day he wrote that the seat was done and he was shipping it back to me! Holy crap!!!

So how does it feel? R E M A R K A B L E! The padding he uses which is a special Tempur-Pedic foam over another proprietary foam which is both firm and lush, much like my Manitou Dorado forks! LOL. The shape of the seat now fits my skinny ass and does not hurt my perineum area. I’ve never had anything suede but I can tell you that it’s a fantastic choice. It’s not yet winter here but I can tell it will keep me from having ‘soggy bottom’ during the summer. And its ability to keep me in place and not slide forward is fantastic. Just lifting up a bit to readjust my sitting position is so convenient.

Having never owned anything suede I asked James about caring for the seat. He places a waterproof membrane between the seat upholstery and the foam so the foam does not become a sponge for moisture. He does recommend that you don’t get the seat wet either through rain or washing. So I went on Amazon and found a jumbo shower cap that fits perfectly over the seat when I wash the bike. Bingo!

Perfect for when I wash the bike and I’ve used it when I ride in the rain too! Since it’s mine I no longer get into trouble with my gf for ‘borrowing’ hers! LOL

So is it worth the price? Oh hell yes for me it is! $400.00 is not a small price to pay for anything. But for a handmade, well designed piece of craftsmanship that allows me to ride as long as the battery last rather than how long my ass lasts is a godsend. Each of us gets to choose how/why we spend our hard earned after tax dollars. The Sur Ron brings me more joy and fun than I could have ever imagined before owning one. Now James’ seat makes that joy last longer than ever before. (And all guys want to last longer! LOL!!!!) And since I too am a small business owner I love supporting other small businesses that produce remarkable hand made products.

Adjusting the seat angle

A level seat bed! Man I love how this feels and performs. A great way for my calves to hug the seat on downhills!

I have found that I prefer a level seating position on my bike, just a personal preference. My custom Renazco seat was MUCH less sloped to the front than the OEM torture rack. I used two M6 Male Female Rubber Vibration Isolators Mounts and M6x10mmx10mm Female Thread Straight Hex Rod Coupling Connector Nuts to raise the front of my seat 1”. This gives me a really great seating position for both sitting and standing. I have a 31” inseam and now while straddling the bike I’m on the balls of my feet rather than flat footed. It makes the distance to the pegs or pedals much more comfortable over the OEM setup.

The hardware I used to elevate the front of my seat. (what a shitty photographer! blurry photo!)

A close up view of how it looks with my 1″ seat extension.
I also noticed that because the four seat supports which rest on the subframe rails were now no longer in contact with the subframe the seat would ‘flex’ just a tad whenever I landed off of a jump or hit a hard bump. So I decided to extend the seat bumpers using furniture feet. Now there is no flex in the seat. Having paid for a custom seat I don’t want the seat pan to fail that’s for sure!
Just used different sizes of screw on Plastic Pads to extend the seat bumper to my specific elevation.
I just screwed the extensions into the existing seat bumper supports.
Now there is no flex or rocking because the seat bumper supports use the subframe as they were designed.

  1. Mark,

    great write-up and detail. I did a very steep, very rocky 2.5 hours yesterday, and found that my butt and bike have about a 2 hour no pain window. The stock seat and my behind do not have range anywhere near my battery potential, in the rocky stuff. being that I am in my initial catastrophic failure ownership period, not ready to drop the money on a custom seat, but your mods on adjusting the seat angle may be helpful with the stock seat. Not sure right now what is technique v. hardware, but fighting seat position while doing steep downhill is not helpful towards keeping my bones intact. Craig

    • Hey Craig I may or may not ride the same definition of ‘rocky’ as you are encountering. I will say that descending a boulder field is very different than loose rock especially given the angle. Downhill is more of a bitch for me than uphill that’s for sure. I like to hug the sides of my seat to lock me onto the bike. I could not do that with the OEM seat. I’m also not sure how much my staggered pedals give me over mounted pegs. Who knows….

  2. Mark, my leg muscles were actually sore the next day from seat hugging/frame squeezing. probably a valid point on the pedals allowing more or different leg positions. I noted in another post, that I ‘think” having to position pedals to avoid rock impact might be a bit much for me now. The trails that I was on for this ride were very steep, with rocks ranging in size from marble to basketball size. My butt on the seat sort of gave out at about 2 hours, about the same time my mind was getting fatigued trying to stay 10 to 15 feet ahead on the safest line. This type of trail is not what I would call fun, but it is very enlightening about the bikes capability in the ugly stuff. I’ll probably order up the X seat when they are back in stock at Luna, then decide whether to go custom.
