Slipper clutch
 

Slipper clutch for 620ss..!......does anyone know what type will/can fit and which is allowed in DD....

thanks

Rear tyre, 160x17 Diablo... ;)

I think Sigma do one Fil, and yes it is legal because the later bikes have a 'servo' clutch which is a form of slipper.

John

Don,t know about the Sigma, one but the standard one is not worth fitting.

Yup Neil was developing one last year when i spoke to him at the trade expo, Im sure he will be marketing it by now.

Don't know what one to use, but it's certainly allowed under the proposed '07 rules...

1.6.32
For Class A only
The original clutch assembly may be modified or replaced with an aftermarket back torque limiting unit (slipper type).

unchanged from 2006 nick:)

If you say so Dr.K!

Dr AK to you sonny boy mr GTH:p :lol:

MR H


You have far too much money :rolleyes:

Buy all means fire it over my way when it drops outta all your pockets young man...



:p

Mike, why do you say that?

Ian Leah had a sigma slipper in his (my) bike last year. get in touch with the old man! :lol:

better than std clutch or std slipper that comes with the newer models.?

I thought the idea was that the slipper clutch stopped the back wheel from locking when down shiffting, I found the one (standard Ducati one) fitted to the Multi did not prevent this. Last year when I fitted the rear sets to the Multi I inadvetantly converted it to a race shift patern but did not realise till I was out on track, twice in the race at Castle Combe exiting corners I knocked it down a gear instead of up and the back wheel locked solid:eek:

okaaay

Paul...

Wot slipper have u got fitted .?..the version that comes with the later models or an after market jobby.?

One from a damaged S2R...........which is the same part # as the 620 one, and the one listed in the DP catalogue....

Likewise the 6-speed box, but I'm saving the heads and barrels until 2008 when I go play with the Sport 1000s... ;-)

I ran Sigma slipper clutch in 2006 and can recommend it - I will be running a Sigma clutck in my Thunderbike next year.

Mine was a 5 speed 620SS. The standard clutch has a tendency to grab when coming off the line and I know others have had problems with clutch slip (mine was OK with an extra steel plate in the pack).

The Sigma slipper clutch cured all those problems; it gave smooth take up coming off the line; never slipped (once we'd got the correct spring combinations sorted) and made the bike much more stable on the brakes into the turns - I was a sceptic but ended a convert!

The clutck is a new Sigma development (was a secret till I just blabbed it now!!).

It is based on the standard Sigma device but incorporates some of the ideas Neil Spalding picked up in the MotoGP padocks - specifically it incorporated a set of sun and planet gears, causing the heavier clutch drum to rotate "backwards" emulating the Yamaha MotoGP engine (with its backward rotating crank) and - in theory at least - reducing engine gyroscopic effect.

Having the engine gyroscopic effects opposite to those of the wheels (both rotating forward - usually) reduces the overall gyroscopic effect fely by the chasis and makes the bike more nimble, improves traction and reduces the tendency to wheelie under power.

A lot of money can be a DANGEROUS THING
 

Slipper clutches eek! My old DLS bike with 58bhp, high bars, and std clutch came 2nd in 2005. Boggy's bike won 2005 without one. Is this not a case of over egging the pudding!!!!

Maybe, but could that bike come second next year???? Progress my boy, progress.....

What, like big bore kits and flatslides = fuel injection?

As long as the pudding has fruit...is served warm...and is called a struedel. I'm in!!!

My 2007 bike has one...std I think?? I'll ask Boggy and Baines...

I just ride it and hang on!

Whitch was the DLS bike you had last year who has it now?

you do LOL LOL.......its the white monnie u bought off tony, who bought off me, who bought off Teetol, who got it off DLS when they *closed * and the one that TP is riding next year

the 05 bike lol...be lucky if it makes top 5 .......

no slipper clutch...no 6 speed box......and these are the " 07 " must haves for any DD'er serious in 07..aint they.?

MLC Racing is Dave Ainscough, aren't you Dave. He owns the ex-Clint DeTarnowsky DLS bike, which finished 2nd in 2005.

Chass & Louigi Moto now own the 'other' ex-DLS bike (Mike Dawson's) which Tetol, Fil2 and Couch owned.

Clear? ;)

Incidently, I don't have a slipper (apart from that servo thingy) and it's fine. Don't need a slipper thanks - unless you can't change gear properly???

What did they do in WSB/GP 10 or 15 years ago? Slipper my arse!!

We're riding 60bhp road bikes ffs :D

i want a slipper..just a plain ole ramp and ball bearing model will do fine thanks...

i need a slipper all the top boys ave got em or getting em.?

What do you need one for?

You getting judder into corners?

Backing it in with your 60bhp and whiff of torque?

Spend the £600 on tracktime and learn how to change gear properly :frog: :lol: :devil:

£600..LOL.........u r joking right..i was thinking of the std slipper that comes in the later 620's.....that aint anywhere near £600

We aint all as good as you clearly are.!.....YOU are the man to beat..and if you got a slipper then we all NEED one

Phillip, Phillip, Phillip...

A Sigma slipper (or a Feracci one) are approx £600.

The standard 'slipper' that the later bikes come with, is not a slipper.

I do not have a slipper. I don't need one. Nobody in DD needs one. You don't need one. It's a waste of money. Slippers are unneccessary. This aint motoGP.

You could have the one in my bike... if it was my bike!

I'm not the only man to beat either :frog:

Cheap as chips slippers

:D:D

You should all put slipper clutches in so dom can disappear!!:D:D:D

Don't take this the wrong way Phil, but onc you jump on the band wagon of "I really need this tio compete" you have already lost. You competed with far less a couple of seasons ago and faired quite well. use your ability. Stay smooth and stay upright.

Well said!!never needed one on a 128 bhp 600 Gixxer...
there is no way i would waste my money to get one on a 620 with 62 bhp!!
would rather spend my money on tracktime!!
