Final Version of Sprung Seat

I’ve completed the final version of my seat upgrade. I ended up using 5” springs mounted to some right angle brackets. The seat is from La Rosa, one of their off the shelf seats as opposed to the specific bobber ones.

The seat can move up and down so it’s very comfortable, particularly on rough roads, and I think it adds a classic bobber look.

Stunning! I'm going to look into this, due to the how jarring the roads are around NoVA. There is so much new construction around here, even the mainline roads are a mess.


How did the front of the seat attach? Did you have to modify a bracket for it, or did you use what was available on the bike and La Rosa? Good job!

I've spent my fortune on wine, women, and motorcycles. The rest I wasted on everything else.

What's it like at speed over bumps? I may be wrong but I'm imagining the seat crashing onto the frame followed by the rider getting catapulted off the bike with the combined rebound of the seat springs and suspension!

Like this, good job mate, you've won me over. The black springs as opposed to chrome compliment the retro brief..........seriously contemplating going up the same path but was a little concerned about the seat pan rear bolt displacement and spring alignment to frame . Almost? 'plug-n-play'. Definitely going the same way. Did you use the La Rosa hinge or some other proprietary item.

I prefer the distressed leather look myself, was waiting for the missus to ask me what I wanted for Christmas, but that never happened! still sitting in my 'add to cart' wish list.

With you on this dude, the distressed leather looks awesome. I'm after the same style seat with that exact patina to the leather.

I used the La Rosa supplied mounting bar and bolted it through through the space where the existing seat attaches. (Attached photo shows this better). The only modification I did to the front of the seat mount was to drill the holes in the La Rosa mounting bar out to 10mm. This meant when I used a 10mm bolt the front didn’t move around from side to side.

Haha, well that hasn’t happened yet! I inadvertently hit some pot holes at speed the first time I took it out and the jolts I felt were less than with the stock seat.

The shock absorber still does the majority of the work, the seat springs just add a small bounce and the force of the rebound is nowhere near enough to catapult rider off bike.

Could you put a link to the parts you bought?? Iím in the UK so itíd be expensive to get the wrong stuff shipped out..
