Fork cartridge info wanted

Aside from the this. Just hypothetically, do mean that if Red or Peit or Keith had the ability to assert their own rules and standards to protect their business on the Laverda Forum, you'd put up with that? I doubt it. Do any of us really want to be told how to behave by a motorcycle shop while we discuss our motorbikes. Bit silly really.

Neither Red, Piet, nor Keith have any financial attachment between this forum and their own business. If this forum was attached to their commercial website, where they do their business, and was fully funded and operated by them as part of their business structure then they could apply whatever standards they pleased.

I am forever grateful that this forum is NOT attached to a commercial enterprise and that all information can flow freely, barring of course libelous comments.
 
I think the gold ones are TiN-coated.
Not sure about the black stanchions. I read somewhere about a DLC coating (diamond-like coating)
 
Hi Guys

More info - With thanks to Eldert from the Ducati MSN forum.

"i use Marzocchi top caps , i had to shorten the Yam forks and cut Marzocchi treads in them on the lathe . for the aluminum demperrods i used the Kayaba pistonring . i found a guy that has a shop that specialises in honing , he has a big machine that goes up and down by itself . he made a jig to hold down the bottomsliders and mounted that to the machinebed . al he has to do is give the mandrel a few clicks so it expands and there goes the machine again . the bottom slide bushing you can get from Yahaha . for the top one Kawasaki is the supplyer

for the cartride i think i was from a Honda 600 from around 95/96
( my brother is on vacation , cant ask him )
but there are plenty more cartridges that should fit

we did a lot of 35 mm forks like this . here is a picture of a internal valve of a 35 mm Showa fork from a Yam RD 350 . the other picture is of a damperrod i made to mate a Ceriani bottom slider to a Honda NSR 125 fork tube"

Impatient pair aren't you. Give brother Eldert time, he's busy workin on real bikes.
 
i found some info on the net about this

http://www.rzrd500.com/phpBB2/viewtopic.php?p=51015&sid=c5158012f51409dfba033820c026db74

but its not as easy as he makes us believe

i bought a set of R6 forks and removed the cartridges .  i removed the bottoms from the cartridges
yesterday and thats how far i got .

first the i.d. of the 38 Yamaha forks is 33 mm . the i.d. of Marzocchi and Ceriani 38 mm forks is 32 mm
so there is no room for the top out springs

the outside diameter of the R6 cartridge is 24 mm . there should be smaller o.d. cartridges out there
Triumph Daytona has 22 mm o.d. but i dont know what year precise

anyone working at a bikebreaker or Triumph dealership who could check things out ?

the only positive  thing is the cartridge has M12 X 1.25  threads in the bottom so could be mated to a Marzocchi fork bottom  ( Marzocchi uses a M 12 X 1.5 bolt )

I guess that is why Maxton now do the complete thing themselves, including machining the fork legs  ::)
 
I've just bought a set of VTR 1000 cartridges and rods. The bloke I know who's done all this before reckons they fit with out too much modification apart from the shoe (to mate the sliders and stanchions) and the length. He didn't mention anything about the diameter being  a problem. I'm modifying Cerianis by the way.

This little job won't be done for a while yet because I've got the chassis to sort out first but I'll post up the process as it occurs.
