| Mounting an old school sprung seat - hardtail/BMW R11 project pix
I'm way too big to use the stock seat, plus it just would NOT look right for my project, so I'm going to mount an old school flat sprung saddle that will be mounted and supported from the FRONT only - just like they used to do! The aluminum plates will have to support 215 lbs. and four times that amount under load when I hit a large bump. They'll be mounted to the 4 stock welded on lugs. They've been tapped for 10mm grade 8 allen head bolts. The seat will actually hang over the rear tail light on a leaf spring mounted underneath. The seat will pivot up and down from the front. The space between the plates will be a great place to hide all the excess wiring from my 12V accessories. |

I've got the sprung seat finished except for replacing the foam with dual density visco elastic foam (memory foam) and then making a cover out of perforated Alcantara. Why not have a comfortable seat? The shock is adjustable for preload and damping, the tail light group came with my Lifan accessories and is attached to the OEM tail light bracket.

Great idea and great work, but isnt it a little out of proportion with the tank ? Will you raise the tank at all ?

I was thinking the same. It looks like the seat will be way too high and too big in comparison to that tank. Anyway, I'm very interested to see this project when it's complete!

Well, since I'm 6' tall with a 50 inch chest and 220 lbs I'm just a bit out of proportion with the bike as WELL! I think once the new fenders (Chaly) are mounted they will help to visually "balance" everything - since they are kind of heavy looking - even though they are plastic. I'll paint them black. I'm probably going to paint the front triangular seat support black to make it appear smaller. |

Nice craftsmanship on the seat by the way. Just a bit high in my opinion though, but hey its your bike and if you like it then thats all that matters. | |

The seat height is now 31" - about 5" higher than before and 6" farther back, but most importantly it will keep me from being so jammed - plus wheelies will be a cinch! | |

I finished the seat today - gettin' there... pretty comfy - I might be able to ride it for an HOUR non stop! The reason I'm building this is to use it at trade shows to encourage potential customers to come up and sit on one of our seats. That seat would retail for $475.00. | |
