Question from a Desmo Due would-be racer...
 
Would anyone be able to help me with this........

What is the significance of a "Legend" logo on the seat unit of a 1996 600ss??

It has black wheels, swing arm and footpegs (hangers)

Was it a special edition or do they have all have that??

Excuse my ignorance but I don't know anything about these bikes:(

Many thanks peeps

An exhaustive two min web search has failed to turn up anything on a 600SS Legend. :D

Sounds like a home made jobbie. Be careful you don't buy anything that'll need major changes later to comply with the rules. Check that the swingarm is still steel, the forks non-adjustable (except preload), and the wheels standard brembo items.

Cheers,

Ali

thanks Ali,

tried the net myself but without much joy

the owner tells me its all original as far as he knows - most odd

I'll check the parts you mention

cheers

uncledunnie 24-Nov-2004 10:48

does this look fairly "normal" to you chaps

uncledunnie 24-Nov-2004 10:48

close up of the front end - twin discs

Iconic944ss 24-Nov-2004 11:16

Hmmmmm....my searching turned up the same as Ali.

Black fork bottoms are a nice touch but dont look at all std to me.

An import of some sort maybe ???

ali 24-Nov-2004 11:33

Hmmm, something not quite right about this one....

The black wheels I could go for (as one year of the SS had 'em), but the black fork bottoms and disc carriers look distinctly home made to me. On the bonus side it's sporting a pair of shiny new goldline calipers that, again, don't look original, but would be within the DD regs.

I'm still not sold on the whole Legend ltd edition but it doesn't look like you'd have many regs probs, it's already got twin discs, and it'll be a bit different from the rest. What's the guy asking? About £1350??

Cheers,

Ali

As far as a Desmo Due racer goes it looks suitable to me, looks like most oyher 600SS's with a bit of black paint added to fork legs and disc centres

Monty 24-Nov-2004 12:44

"As far as a Desmo Due racer goes it looks suitable to me, looks like most oyher 600SS's with a bit of black paint added to fork legs and disc centres"-I reckon that's 'go faster' black paint tha know's Skids-reckon we might have to give him a weight penalty................:lol:
Looks ok to me Uncledunnie, if the price is right go for it.

fork bottoms have Ducati cast into them so legit I am assuming

The chaps asking for a bit more than that, but we're still talking - just want to be sure about what I'm buying before I commit

Iconic944ss 25-Nov-2004 01:55

Hmmmm...the more I look, the less I see (how deep !!!)

The Goodridge hose guide - shows 600SS from 1994-98, listed with only one single front hose, with the 750 and 900 for the same years - also getting two hoses.

http://www.goodridge.net/appguides/UK_sportbike.pdf

The parts fitted all look very original OEM Ducati bits and should satisfy DD rules.

All the stuff I've read so far suggests using a 900ss m/cylinder - one of which I have spare if its not fitted already.

:lol:

KeefyB 25-Nov-2004 06:55

Yep 600SS came with a single disc setup as standard.The fork bottoms and disc carriers have probably been painted black as a result of a missmatch,or they were bored!
As for the Legend thing,I think that will be just a decal that some owner has fitted.(Probably the same person that painted the forks!)
As someone else mentioned,check to see if the master cylinder has been uprated to cope with the extra disc.Look at the numbers stamped near the lever pivot.They should end with 16.(16mm bore)
If the numbers end with 15 or 13,budget for a new master cylinder.

skidlids 25-Nov-2004 10:06

A couple of years ago I purchased a N reg 600SS with a standard twin disc fitment front end (lugs on both forks but only one disc and calliper), but as the forks were very pitted from flood damage I replaced them with a set from P reg bike and these only had brake lugs on one fork.

uncledunnie 26-Nov-2004 08:42

thanks for that chaps,

I fairly happy with the little bike and the price, but......

I do have one remaining concern and this point is really directed at the rule makers.

The regs state no work to the cyclinder heads, but I can go to the big bore conversion - so if I do buy the bike I know I will want to go big bore so does that mean I'm stuck with the 600 heads?

These things have tiny valves and because of their design I understand that fitting larger valves is virtually impossible / expensive. If I'm correct from the info I have gathered the 600's biggest drawback to performance enhancement is inability to suck air - due to the restrictive valve arrangement, so.......

1. In doing your calcs re performance balancing between the big 600's and the 620's can I change the heads during the conversion? If so what are the regs regarding that?

2. If I cannot change the heads on conversion I assume the figures you have been working to mean a larger bore 600 with stock 600 heads will match a 620 with some simple carburation mods.

Perhaps the powers that be could clarify that one for me.

I'm becoming a bit sceptical that an overbored 600 with stock heads and cams and free exhausts will match a 620 with free exhausts and fettled fueling.

600 approx 50bhp stock Vs 620 63bhp stock, I could see a 620 going to low 70's quite easily but a 50% power gain on a 600 is starting to look a bit optimistic in my eyes.

Any one put my mind at rest, I can't see the point of forking what looks like being the best part of £3k on a 600 with overbore and other mods to find its not competitive (rider ability excluded!) against a much cheaper to modify and easier to sell-on 620.

Any one else had thought along these lines?

dickieducati 26-Nov-2004 08:55

very simplistic from me but i will be going for a 620.

uncledunnie 26-Nov-2004 09:17

I wish I had your clarity Dickie!!

the spanners are screaming "sort a 600"

the brain is starting to murmer "just buy a 620"



:puzzled:

dickieducati 26-Nov-2004 09:31

well for me im not a great one for fannying about with bikes, mainly because i havnt got a clue what i'm doing so i want the most easlily available horespower so in my mind that is a 620. it also give you a higher base level to start from if you do want to fettle things a bit. sure it will cost you a bit more initially but there is no such thing as a free lunch.

skidlids 26-Nov-2004 09:37

Good point uncledunnie, if I was fitting a big bore kit I would certainly like to get the Squish sorted to suit and reduce the risc of detination.

Not sure I would want to go through the hassle of bigger valves but better shaped one piece stainless valves would help both gasflow and reliability and then a camshaft reprofile with different lift and/or duration would again help gasflow.

Still that would be a silly amount of money to spend to try and beat some 620s, be better off trying to beat all the other 583cc bikes out there for a lot less cost.

Then if racing is for you move to a SoT class the following year, for about £3500 I could put a 748R on the track (my 748SP + 748R engine package that Nelly had for sale and sell 748SP engine and injection on)

Felix 26-Nov-2004 10:16

Kev, you continue to amaze me. Of all the riders I know, both track and race, you fettle the most with lots of bikes. I envy your activities. :cool:
Sounds like a dream to me. :)

ali 26-Nov-2004 10:39

I'm looking at DD as a two model series. I'll be out to chase the other 583s, and if I pass a 620 or two then all the better.

If things are looking up on the work front later in the season then I might invest in a 675 kit and a cast iron disc (or twin disc set up), as I think a lot of time can be made up into, and coming out of, corners. The big bore should give similar torque to a 620 for the first few yards out of a corner.

Having said all that, if a bashed-about 620 comes my way between now and May then I'll do my best to find the reddies.:)

Cheers,

ali

Interesting points of view peeps.

I'm using the Desmo Due as an intro to racing - if I click then I could see me moving onto bigger classes in a couple of years times. But I know me and I would not be happy running around on a bike never capable of winning a race (again, rider talent excluded) and to me that somewhat defeats the object - otherwise track days would be my thing.

So, I would like to know from the rule makers what is permitted technically when it comes to the 675 conversion - I believe Monty or Chris posted something a while back about striking a deal with someone about this.

Having done all the research I can on the bike options, the answer to this question will now be the deciding factor in my choice of machinery.

Oh, and regarding the 600ss I have been looking at, I finally managed to speak to the original owner who did the work and he told me...

"Legends" - Glasgow bike dealer transfers!!!
Swing arm, pegs, wheels, fork bottoms all powder coated black by him.
Twin disc and caliper from a 750 (?) fork bottom already had the fitting for the second caliper.
Stock m/cyl - brakes are a "bit spongy"!!!!!

Iconic944ss 29-Nov-2004 11:48

Well, at least that's the 'Legends' mystery sorted.

It least the bike has braided hoses fitted so with good pads it should still stop OK - new fluid and a good bleed might be all thats needed.

There seems to be quite a few bikes around at the moment for sale but I guess this depends how much you can/are willing to travel to get a 'good-un'.

Good luck - Frank
