851 Corse Replica

Discussion in 'Builds & Projects' started by iambadgerous, Jan 4, 2013.

  1. Hi All

    I'm new here so I thought I'd share my on-going project with you.

    She started life as a 1989 851 Strada but all that now remains of the original bike is the frame, swingarm and shock linkage and she's pretty much a Corse replica. It took me nearly 3 years just to find all the parts...


    The current spec is:

    Frame: Original 1989 851, powdercoated. 851SP alloy rear subframe

    Engine: 916cc from an ST4, standard apart from lightwight clutch basket and pressure plate, painted to look a bit more 90'S

    Front End: Later 851/888/900SS yokes (original bike had Marzocchi M1Rs), bottom yoke shimmed down and top yoke machined out to 53mm to take late 916 Showa forks, 916 clipons, 916 front wheel (because it looks a bit more like the Marchesini mag that the racebikes had) and carbon mudguard. Brembo Goldline 65mm calipers

    Rear End: Original swingarm and (sexy) adjustable shock linkage, Ohlins shock, 900SSie wheel (to match the front), carbon hugger and under swingarm hugger, carbon chain adjuster plates, underslung rear caliper with Corse carbon tie-rod

    Induction: Corse carbon intake system and airbox, S4 throttle bodies with pod air filters

    Exhaust: 50mm spaghetti headers and carbon cans, carbon hangers

    Bodywork: Nose and sides are repro from QB Carbon, genuine Ducati Corse carbon tank with quick-release fittings, tail is genuine Ducati carbon, carbon upper bodywork mounts, paint by Darren Flynn (DF Bike Paint in Bournemouth)

    Controls: Corse alloy dash with ST4 rev-counter and 851 temp-gauge, custom made (by me) loom with 16M ECU and all relays, fuses etc... mounted in the nose to keep the undertail clean like the Corse bikes were, repro Corse alloy battery tray, Brembo master cylinders from an Aprilia, 'Map Select' button is actually the horn, Corse alloy rearsets


    As far as future plans go, I have a 996cc motor from an ST4S which should slot straight in, a nice pair of Ohlins FG9051 forks (as fitted to the SP bikes) which will need a new top yoke machined out to 51mm and some spacers to make the front wheel fit, and some billet Brembo calipers. I also want to do a 'big axle' conversion by modifying a later (and stronger) Monster swingarm to take a 25mm axle and running an ST4 rear wheel. At the same time I'll install a different Brembo rear caliper, the triangular shaped one used on the later Corse bikes. I also want to change the ECU for a P8 but that will involve another new loom...

    I think that sums it up, I'll post more as work progresses.

    Cheers
    Darren

  2. mike,
    I absolutely L O V E whet you did on the strada.
    depending on what you can do however ( dosh wise) : if you're having a corse carbon tank (waw!), then you would give the project a great 'corsa' boost buy sticking on the front Ohlins forks and Brembo billet calipers and floating disks.
    if i'm not mistaken the lower fairings have a black band running donw to the lower pipe.

    :upyeah:Koen
     
  3. Hi Koen

    The picture you posted is a road-going 851SP model (not a Corse bike), probably an SP3, these had black painted lower fairings as you describe.

    Some (maybe all) of the customer race-bikes (known as the 851 Racing) had black lowers but rather than paint this was bare carbon. They also had a black band around the numberborads. Here's a picture of a 1991 851 Racing, these were widely known as the 'Raymond Roche Replica'.

    Most (again, maybe all) of the factory race-bikes had red painted lowers and the numberboards had a white pin-stripe around them, this is the look I'm going for. Here's a picture of Giancarlo Fallapa's 1991 works Corse.

  4. Now where did Mike come from :rolleyes:

    Waht a bike...
    Waw! i'm with you now! if you want, i'll keep an eye out for some specific parts you may be looking for..
    i think i saw a pair of original brembo monobloc billets go by for 600 gbp... ( 1/3 of the price)..

    i know someone who's been loading up on this stuff for ages and perhaps their is some stuff he no longer needs/wants..


    are you after that sort of stuff or would it kill the misses?. :smile:
     
  5. Hi Koen

    Thanks for the offer but I already have all the parts I need, I just need to find the time to get it all done...!

    Cheers
    Darren
     
  6. hi darren,

    even better! can't wait for the pics! :)
     
  7. what a Class 'A' total cracker of a bike - already had Fallapa's bike as 'my' wallpaper :upyeah:
     
  8. Gorgeous! Another one of those bikes that's on my future project list!
     
  9. Lovely bike, number plate looks too upright for me tho.
     
  10. Ooooo that's pretty nice
     
  11. Jeeez... there's no pleasing some people...
     
  12. have to agree though Darren :smile: - take it as a back hand compliment - bike is so close to perfect that the very slightest of 'things' stick out like a sore thumb
     
  13. He has got a point ;-)

  14. plus don't know how much you weigh/how far rear suspension travels in use but could get a bit close to tyre on occasion - it's happened to me on Monster despite what I thought was a healthy gap.
     
  15. Actually I do agree :wink:, in fact it's something I'm going to change when I do the re-build.

    When I built the bike I became so obsessed with carbon that I even wanted a carbon number-plate holder, but carbon doesn't bend.

    I'll going to make a new one from some sheet ally...

    Cheers
    Darren
     
  16. glue a carbon plateholder on a bent aloy holder... :smile:

  17. Amazing work Darren. I love it :upyeah:
     
  18. Looks amazing.
    Doesn't seem to have a headlight, so does it even need a numberplate?


    I'm confused.
     
  19. Hi, here in the UK we are allowed to have a bike 'for daytime use only', so no lights required...

    Darren

     
  20. Darren,i think you might want to check ebay out,theres a set of magnesium 888 wheels on there at the minute!
