Ducati Monster Forum

I'm Ricky from racecitypowersports in Mooresville NC Our latest project is a rigid bobber with a v twin from a Ducati 900. We started this project after we finished our Motocreations Hyper Devil. Old school bobber with Ducati Power and braking.

I like it-but I've always been a sucker for springer front ends.


Looks like a fun project!

I'm liking it. I think the biggest thing for me is that the Duc motor looks like it belongs in the frame and here it does IMHO. Nice work.  [beer]

I'm not much of a chopper guy, but I do apprciate a good bobber and the idea of one with a ducati 900 engine works for me.

nice job!

Damn thing needs a seat! [laugh] Pretty cool scooter. Choppers no, old school bobbers yes! [thumbsup]

I love old school bobbers, but there is too much negative space in that frame for me Right now. It will be interesting to see it at 100%

to each his own...

[roll]

It still needs a battery, seat, oil cooler and a few misc things.  They should take up some of the negitive space.

That's why I said I want to see it at 100%  :) it should be interesting. I'd love to build a custom bike using a Duc heart, so I'm interested to see where this ends up. I think it's a cool idea.

Is that hyper devil the one with the burnt orange paint job? If it is I will say this: you guys build cool bikes, but you need to fire who ever designs your paint schemes. That burnt orange is one of the ugliest colors ever to appear on a bike this side of a Pontiac Aztek. And that grim reaper on this bobber is so "Bad Ass" trite and cliched that it looks like it was designed by a low rent tattoo artists in the wrong end of Hoboken. But other than the paint (and maybe how high the headlight is) its a cool looking bike. How was the engine modified?

I think the pipes and motor mounts kill it for me. the pipes just based on personal taste (to modern for me, but its not mine so make the beast with two backs it) and the motor mounts make it apparent that really any engine could be in that frame (and that a more traditional british or american motor would probably suit it better)

but its also clearly unfinished and im sure the remaining work will make it flow better. [thumbsup]

no, just  [puke]

Very cool for what it is. [thumbsup]

I'd ditch the mural on the tank...but that's me.

[laugh]


I was being...polite.  [cheeky]

Bobbers are just too played out. 

Seen the same pipe configuration on a ton of choppers.

Headlight is too high.

How do you check the oil level?

I really like it, but I would also lose the Grim Reaper and do something that picks up on the unique Italian motor.

Like motor mounts that don't look like an after thought? Its like some one fabbed a cool frame and then they had to decide what kind of motor they could wedge into it. well that Sportster 1200 didn't fit, but I know a guy who just wrecked a 900SS.

The more I look at this bike the more it looks like using a Ducati 900 was not part of the original concept. Is that the case here?

sac

Another vote for losing the Reaper. Way played out...

The rest I dig.  [thumbsup]

The frame is a kraft tech. Originally made for a Harley type v twin. This bike is being built for a customer that wanted a ducati engine in a old school bobber type frame. The customer didn't want to pay for a one off frame. So we needed to make a mounting system that would hold the engine and give some rigidity back to the frame. There are not many options on how to mount this engine. We needed to make the mount removable so if the engine needed to be  removed for any reason it could be easily done. Its easy to say the mounts look like an afterthought but when you explore your options there are not many solutions that  are safe and strong enough. Also the reaper design was at the customers request.(not my choice) You can check the oil level very easy the sight glass is in plain sight when you get at eye level.

Nice work Rick.


Bobber's don't have front brakes. [cheeky]

THIS is what a Ducati 900 bobber should look like... [evil]

Then again, I'm more than a little biased...  ;)

I actually like it better than Stu's bobber. 

Hey guys with much feedback I lowered the headlight. I think the lines look better.
(http://images.psndealer.com/dealersite/images/racecitypowersports/bobber9.jpg)

but how do you check the oil level?

Its an answer to a question nobody asked.

The reason for the underslung frame (on most older bikes) was that the frame needed to hold the engine from below.  On Ducatis, the engine IS part of the frame.  So doing a Harley wannabe bobber with a Duc engine looks like crapola IMHO.

it just....it hurts right *here* you know what i mean?  :-\

this is where the build was doomed.

So, it's an out of the catalog Paughco with a standard Sportster peanut tank, 21" front wheel with Avon Speedmasters on it, repop springer front end and PM-look (Brembo) cantilevered brakes?
 
Yep, recipe for an HD bobber.   [roll]  "I want to be a rebel" the customer says.  "I want to be different and put a Ducati engine in a bobber".  And winds up looking just like everyone else.

Needs tassels and an FTW clutch cover.

Can't be a rebel by building a bobber anyway.  No matter what motor you put in it.  Nothing original about a bobber.  Been done to death.

How does one "leave a bike alone" ??

Does not compute.

;D

I would have made this for him then:

I like it.  Doesn't make me wanna run out and buy one just like, but I like it (though I'm with everyone on the grim reaper thing.  But if that's what the customer wanted . . . ).  

I know the customer didn't want a one-off frame, but I wonder if ya coulda taken the motor mounts continued them with a mini trellis 'til they met near the middle of the engine.  It'd look like a mini-Duc frame.  Actually, now that I think about it, that would prolly look like dogshit.  Forget I said anything.   ;D

FWIW, Duck-Stew geared his bobber really tall.  The multiple times I rode it, the tall gearing worked really well with the Duc 900 motor.  It slowed it down a bit off the line (and was hell on the clutch on start n' stop San Francisco hills), but stock gearing would have had too much sportbike thrust and ruined a little bit of the hybrid bobbber/Duc feel.  It's an easy change, but it's something to think about.  

I build custom things (ginormous homes) myself so I am completely sympathetic to the fact that the guy writing the checks can completely (or partially) ruin what as otherwise a really great build. If you can't talk any sense into them all you can do is point to the great quality of the ugly POS you were forced to build.

^^^^ What he said.

Personally I like most of the bike. The parts I don't aren't that big a deal.

I like it more and more as I look at it.  :)

If it were mine:

1. Strip it down, blast, and repaint the frame, wheels, and bodywork in satin black.

2. Lose the clutch cover entirely, or go with one of the super-minimal ones made out of wire (which, chromed, would echo the wheel spokes to a degree).

3. Lose those timing pulleys in favor of more mechanical-looking, black-anodized machined billet units. Those in the pics are too froo-froo.

here's an olde skoool Ducati Choppa

Fortunately, there's no Ducati Monster groupthink when it comes to mods ... such as Termis, CF everywhere, open clutch bling, Corse decals, etc...  [roll]

AAAHAHAHAHA, one of my most favorite lines... "i'm not"  SHHH SHH SHH!

I love all the controversy. When i did my 'hyper devil i got the same. 
'I love to build things different I love my ducati's I guess you guys wont like my ST4 with a champion sidecar. ;D
I thank you all for your comments good or bad that's what makes these fourms intersting,

DUDE.....I want pics of that!!!

That makes me sad.

 [thumbsup]  kudos on your strong ego..  more people need a thick(er) skin like this..

For the record the ST4 hack sounds pretty cool, maybe some pics?

seconded. haha... because anything with a sidecar is automatically cool.

Keep the thick skin! even some of the harsh comments can be useful. I went through the same on my build heres a shot of it. sorry bad link here's the build http://www.ducatimonsterforum.org/index.php?topic=11758.msg845792#msg845792 (http://www.ducatimonsterforum.org/index.php?topic=11758.msg845792#msg845792)

tease....want more!!!

haha awesome

fek yeah man - that's the plan on on my fixer upper M900.  use some old school 916 doodads

I can appreciate different projects but a few things that from my perspective: 
1. L-Twin (sure, a variation of a V-Twin, but quite distinct in layout).
2. Rigid. I would much rather ride a 'softtail' if the motor put out any power - but see #3
3. Ducati Power.  It certainly won't be overwhelming (though not far from the average 'v-twin' mills claims I read about).  The whole package will look better and perform significantly better if you stick short manifolds and split-single keihin carbs on that thing. I mean GOBS better looks and go-fast.
4. Braking - if you want to really pull off a cool bobber / minimalist look, ditch the conventional rear rotor and rear sprocket, and pick up a combined rear rotor/sprocket setup from ISR:

(https://www.choprods.com/components/com_virtuemart/shop_image/product/resized/ISR___LACC_6_Pis_4da37c64205a6_250x250.jpg)

Hey do you have experience with shortened manifolds(how short) and Keihin carbs I would like to learn more about that. As for performance  this bike moves out  Not much weight and plenty of torque but tricky to tune. tell me more about this  carb and manifold  mod Please!!!

I ordered a set of short manifolds from Jako Motorsports in Germany awhile ago to fit Keihin FCR 41 split-singles awhile back.  But they have been sitting on the shelf for awhile with other projects taking priority here and there.  Many people use Mallossi short manifolds iirc, but I don't remember which number.   I'm sure the likes of Ferracci, DucPond, Nash @ AMS, or the rest will know.  Its quite popular with the track-oriented 900SS crowd.  Downside I have been told is more tedious sync'ing the carbs requirements, lack of airbox also means things mounted to airbox need someplace to go, etc.   The Keihin 'kit' (doesn't include the necessary short manifolds) is 016-747, MSRP of $1000+, and can be had from board sponsor CA-Cycleworks: http://www.ca-cycleworks.com/fcr-split-singles (http://www.ca-cycleworks.com/fcr-split-singles)

At a show I saw a guy with a Monster using that setup (fcrs and short manifolds) who had fabbed an airbox from fibreglass.  He found some intake ducting with curves that connected to it.  It was pretty trick.  The filter was a stock ducati filter. 

I had pics in my phone.. somewhere.

like ziss?


(http://www.jako-motorsport.de/images/Dellorto900SS.jpg) (http://www.jako-motorsport.de/images/Dellorto900SS2.jpg)

or not too different from that, i mean?

yeah, but those are PHMs not FCRs -- the airbox this guy had was hand-laid fibreglass

I wonder how well Dellortos do?  I have a shitload of them in my garage.

Details details

also, the PHf/PHm carbs are side draft with a max angle of 45 deg.. that's way more than 45.

Well I dont know anything about 'em, or the aftermarket flatslide mikuni's... He does make some awesome power and slick looking bikes from what you can see online.  See his rocker shaft relocation kits? ...interesting...

whoa.. waitaminit...

(http://www.jako-motorsport.de/images/foto_vergaser_01.jpg)

crazy bastard designed a float bowl so the PH can be used downdraft style.. wow... talk about nuts.

(http://www.jako-motorsport.de/images/foto_vergaser_02.jpg)

Yeah, he's no joke. Likewise, he came up with his own timing pickup setup using the layshaft & driving pulleys

it's been done before on bevels, and it looks like shit.  i mean, the engineering is handsome, but when you stick that on the outside of a Ducati, it just looks Frankensteinian.

never seen on a full-faired SS, so no big deal there: he's track oriented
