It looked hard to do but turned out to be easy, as there is an indentation cast on the bottom seat mount that is dead center to the the spring mount castings. Dykem and a compass made the lay out easy, then I just leveled each casting flat to my drill press.

Great quality seat pan, exactly what I was expecting !

Seat is solid as you can imagine from a cast aluminium construct, provides blank slate to customize.

First impression of the seat upon receiving it. It's exactly as advertised. Haven't installed it yet. I believe it will work on my project very nicely.

This seat is killer especially at such an affordable price. Arrived today and I'm still sporting a hard on. The tech tip on mounting it is very helpful too.

The seat is awesome and price was affordable too!

Saw this on a bike this past summer, knew right away I had to have one. Managed to ride the bike, I was surprised how comfortable it was. Just got mine today and am impressed.

This is my second cast seat. I cut this one narrower and ground off the back mounts so it sits on some rubber bump stops. Polished the underside and Line-X the top in shinny black sparkle. Being solid aluminum, its indestructible, very easy to cut, grind, sand and polish. Also it is comfortable even without padding do to the nice shape.

well polished it and put it on the bike it changed the hole look of the bobber. just look good polished but sky is the limit with a seat like this,happy rideing from australia get one

In my case the rough cast finish matches my framework perfectly. The seat is very well built, no need to worry about it being made of aluminum.

Nicer than I expected. Wondered about threads in aluminum so I think I ll just drill the fasteners thru.

I love how it looks on the bike! my rear is numb after the first ten miles. I planned on drilling holes...only got as far as polishing.

Got this for"Lester" the Hondamatic. (Google it). Sanded polished and engraved, no seat looks better. You will NEVER wear out this seat. And after several thousand miles, it still looks great and is deceptively comfortable.

No affiliation with LA Nik but he did a pretty cool mod of this seat on his bobber project. see the video here: http://www.youtube.com/watch?v=wYL8X1qEPUI I have to say, It would have been much sweeter if it was polished first.

I thought an hour or two I think I'm unlucky, while sanding to remove some minor pitting and tool marks, I exposed a small air bubble that was just under the surface. I thought I could have it polished and mounted in a night, not going to happen, I've got a lot of material to remove, or maybe drill a bunch of holes through it, or engraved it. Either way, I don't regret the purchase, when I'm done it's going to be sweet.
