The Biposto to Mono Conversion
Ducati 996 Biposto Masquerades as an SPS!

The whole idea is to duplicate enough of the parts required, so that you can swap from bip to mono and back again in just a few minutes.

The thing to avoid is having to unbolt parts from one seat to put on the other - they're cheap enough, so simply have all the appropriate brackets on both.

Here is the bike in the mono configuration. Re attach the foot pegs, swap seats, and in 3 minutes 20 seconds, it's a Biposto again. Marvellous!

One nice thing about going from bip to mono is that you don't need a new sub frame. If you've got an SPS and want to go from mono to bip on the other hand, you'll need to add a new sub frame to cope with the extra weight of a passenger, and you'll need rear foot pegs too!

Also shown in this photo is some 2mm silver foil backed insulation foam which I've stuck on with double sided carpet tape to act as a heat shield. It works amazingly well and now keeps my bum and legs significantly cooler now that summer is here.

With the SPS tail unit, there's a lot more room under the seat for all sorts of goodies.
Just remember to secure anything you put in there because there's no passenger seat to keep it all snug - as I found out; one lost mobile phone later...

Ho hum.

Bits you'll need to do the conversion:

   Part Number       Description

  438.2.019.2NA   Rear fairing (Red)   (438.2.019.2NB for Yellow)
  827.1.086.1A     Seat bracket
  777.5.234.2B     Screws for bracket above (x2)
  595.1.027.1A     Seat Assembly (includes rubber pads x4)
  866.1.023.1A     Right hand pad
  866.1.024.1A     Left hand pad
  827.1.120.1A     Plate
  829.2.004.1A     Holder
  713.1.109.1A     Spacers x2 (which I think is 4mm too long - but check it first)
  779.5.009.1A     Screws for spacer above x2
  525.4.005.3A     Tail lamp assembly (includes bulbs)
  827.1.111.1A     Plate for cable connector
  866.1.018.1A     Rubber spacer
  866.1.020.1A     Rubber Stoppers x2
  764.1.024.1A     Rubber Grommets x2
  832.1.008.1A     Pins x2

Have your local dealer check these part numbers - I'm fairly sure they're correct, but I'm in the UK, your part numbers may differ. You'll also need 4 nuts, (5mm hole, which use an 8mm socket), and four washers. These attach the seat to the fairing. Total cost here in the UK: 528.64 using all new parts.

Oh, and is just me, or do Ducati part numbers look like IP addresses on steroids?

Here's how the brake/tail light assembly all hooks together on the SPS tail unit.
Adjusting the position of the bracket with the two black stoppers on it allows you to adjust the distance between the front of the seat and the fuel tank.

The pins which the blue grommets fit over can either be screwed into place before you've got the black plastic brake light assembly attached, or afterwards. If you do it before, then quite a bit of force is required to compress the little rubber spacer between the tip of the tail unit and the lights (not shown) so that the grommets fit over the locating pins.

I did it by screwing in the pins, then pushing the brake light assembly with grommets attached onto the pins, just be gentle and it'll be fine.

The spacer shown here was supplied with the bracket, but left the tail unit very high, and quite odd looking. I whipped 4mm off each spacer with a hacksaw and refitted to get the result you see in the finished shots below.

The bolt shown (x2) loosens to allow the bracket position to be adjusted, which in turn allows for the seat backwards/forwards position to be set.

Don't forget to get this little bracket which holds the brake light cable connector (in the parts list above).
All done, as viewed from behind...
...and from the side.

Don't forget to remove the passengers foot pegs or the entire effect will be lost!
Also, screw the pax foot peg bolts back into the holes with a little copper grease so that when you want to refit them the screw holes haven't gotten all filled up with gunk.

Job done.
Total time taken: 45mins.

Apart from the Showa forks and rear shock, you'd never know!
