adjustable forks - which ones fit M620?
 

as title, can I fit any Ducati ones, eg 998, 916, 900ss

my guess is yes as long as 65mm spacing for brakes and same front wheel spindle but not sure about yokes etc

thanks

Don't think yer allowed to change them. Any Ducati forks that fit into the standard 50mm yokes.

A you are - can have adjustable forks.

so anything except Ohlins?

You can fit any Ducati forks as long as they fit the standard (for your bike) yokes.

There is a little legal fiddle though;).

sorry, I know I'm dim - I just ride em! - I'm looking at a set of 998 and ST2 forks - will they drop straight into my soon-to-be-mine 2002 M620?

Ducati uses two sizes of forks - 50mm diameter and 53mm diameter.

Yours will be 50mm diameter, as used on most Monsters, Supersports and the other "smaller" bikes.
The "large" bikes get the bigger forks - 916 line, 999 line, 848/1098/1198, etc.

So no, they won't fit!

ok thanks

must check the rules then and see if I can change the yokes too...I thought some were running 996 forks....

Its no Yoke Paul, std ones for the bike, or peeps would be fitting T9 ones etc.

wonder what size M1100S are, nice radial calipers on those :)

would ST2 fit?

900ss or st ones will do just check lenth as some are longer than others i have st ones and are about 65mm longer just means they poke throuth the top yoke a bit more could be good if you wanted to put clipons ubove top yoke ideal for a bad back :D

No you can't change the yokes, the rule is quite clear
So you cant use 996 forks or any of the Superbike range for that matter
As you can only use forks with a upper diameter of 50mm and a lower diameter of 54mm

So who do you think is using 996 forks
Forks from a S4, 900/1000SS and Monster, plus the ST range are all adjustable and all suitable

God knows why I bother writing anything in the rule book as nobody reads it except possibly Chaz who reads it inside and out and then knows how to get the best out of the bike, without falling foul of the rules

but you know most of us just ride em Kev :D that's as far as our knowledge goes!!

And there are all sorts of rules which seem to not always be applied - subframe...balancing crankshafts...batteries

And thats before BHP, weight and the bigger issues we occasionally see

oh and I'm lazy too - and boooored beyond belief but still cant bring myself to read the rules - sorry :)

edited to add I'm also the most angry, annoyed and aggressive I've been in years - how people spend their lives lounging about sponging off the state doing feck all amazes me!! It just makes me want to kill the next person who comes thru the door!!!!!

:lol: better be sorted now!! I have an 848 to ride!

think they must also be on Craigs when you see how far his poke thru

That's the fun part Kev apply the rules as you you see them;)

The only championship winning DD bike proved legal :lol::lol::lol:

I need someone to build mine I think rather than wallow around in the dark, always on the back foot and never close to having a 'good' bike

That was our approach to the TT rule book, try and find that loop hole you can drive a truck through

Since I've been able to make changes to the rule Book most of what you mention above has been rewritten
Subframe - Addressed a couple of years ago and Class A updated for this year
Crank Balancing - Also been updated to allow it, but not lightening or knifedging
Batteries - Again upadated a year or two ago so they are now free, just need to be able to start the bike in Parc Ferme if asked to do so

BHP and Weight are measureable without having to take a spanner to a bike so makes sense to have figure that all can work to

Then on top of it all the ACU has a protest procedure for anybody to use should they feel someone else is gaining an advantage by operating outside of the rules.
I have seen the odd breach of the rule recently, but wouldn't say any of them gave a performance advantage, but if another competitor lodged them as an ACU protest they would be an easy ones to have th rider removed from the results.

Tell me about it. Some of those leathers wer awful. :lol:

Mine was weighed and dynoed at Oulton and available for stripping. 100% legal. :D

I used to work for Broadspeed Racing years ago and Ralph Broad was an absolute master of interpreting the rules to his advantage, without actually breaking any of them.

its an aptitude thing Phil - I just dont have it when it comes to mechanics and getting my hands dirty.

One of the best I remember when I was racing my Mini many years ago. Was that the original gearbox must be retained. I saw this special saloon with its original gearbox locked in 4th gear to give 1:1 output, then passing through to a Hewland transaxle in the back. Fkin Brilliant. :D

bradders if you looking to fit radial calipers, Monster S4R Testastretta (2007-2008) Showa forks are 50mm top 54mm bottom

as the S4RT is a heaver bike the stock spring rate might be a better fit for you then those spongey 620 marzochis

you might need to find some 15mm offset 6 hole rotors though

dont know if any of thats legal for DD mind

thx, probably not unless I come across them super cheap...dont intend to brake that much so wont be too worried about them!! :lol: And they must be legal as Hugh ran them last year in B

mainly looking for adjustability - seems from what I have read elsewhere that the non SBK ones arent really worth having, may as well spend a few hundred quid on rebuilding std ones to suit me and my style

I've got a set of radial calipers that are not being used right now...

If you want to run one radial brake dallas is your man hes brought a pair with brackets to fit them to normal forks he had to buy as a pair but is only running single brake so he has a spare one with bracket for sale :D

Probably the crappy two pin ones, in my opinion the only radial worth changing to is the 1098/1198/848 Evo type, otherewise your not really gaining anything over the 65mm Axial mounted calipers.

Hugh's forks were from a 696 Monster so although Radial mount they are not adjustable like the S4R forks

I sent Dallas a couple of links the other day, one to a set of Radial Caliper adapters for fitting 100mm spaced radial calipers to 65mm axial fork mounts, the other to a set of 1098 Radial calipers.

If he's going down this route he should have a set of 4-pads coming up for sale

not sure whether to go 1 or 2 disc next year, think that extra bit of braking power may be useful

first dibs on those 4 pads please!
