Commando fork

Has anyone installed the Rocky Point Cycle 25 dollar fork upgrade kit?

What's in it?

It consists of a couple blanking dowels, internal bushing that slide inside the dampers to keep from topping out and instruction on how to do the mod. They work good and there is another name for it but I cannot think of it. Covington,cosmopoltan, casworth.........something like that. Somebody help me. Coventry?

Coventry it is.

Are you talking about this http://www.nocnsw.org.au/forks.html
and this http://www.members.shaw.ca/randell/covenant.htm

I've been thinking about if for maybe 5 years now, but the riding I do, I really don't notice any objectionable function.

Sliding collars or extended top bushes to the same than, cover the holes at ~4.5", except the long bushes don't just slide and bottom on the lower bushes, to cover the very holes you want clear until hydro stop. I solved my Roadholders using the damper hole plug kit and remade new staggerd holes above the damper lip and then longer slightly bigger OD 10mm Al rods 2" long so no damper cap colliding on top out, then put in a spring spacer of your choice of rate, valve springs are progressive, or a weak on to retain factory say height and all is well but for fork twist w/o a brace if really hot dogging deadly risking. Greg Fault has made a great kit with his own refinements and there are higher cost - complexity kits that abound on this forum and everyone in glee with them too. Most 'heavy' riders complain with the too weak progressive springs that are off the shelf items though custom ones can be ordered up. I lucked out to snag last of a batch of 3 rate springs. But with the spring spacers and cutting factory springs could brew your own. Btw most restriction is the spring rub in tubes so make sure thats smoothed up.

Covenant.



I used the RGM Covenant kit until I replaced the dampers with the Lansdowne

A forum Search using "Covenant" should turn up lots of information.

On a scale 1 to 10 what is the difference between the standard forks, the Covenant bits and the Landsdown dampers?

5, 6, and 8

FWIW Progressive spring offer little to no benifit, IMHO, and should not be used with the Lansdowne units.

Thanks, I bought a pair of progressive springs and agree they don't make a lot of difference.
Pushing through bumpy corners is a very phsyncter puckering experience,,,,, I've had a couple of voilent tank slapping, firing out of the seat, I'm only along for the ride, scary moments.
I know it's the forks, so thanks for your comments.

If you are pushing into hinged - tank slap flings I can flat grantee it ain't just the forks spoiling your fun. You are asking for it if not getting one of the proven upgrades or inventing your own, nothing in past off the shelf normal marketed upgrades but a good fork brace have any use in improving Roadholders. Once forks are good as they get then you will just up the speed and frequency you run into another innate trait of un-tammed isolastics, just about the time you think you can hang with a modern into a powered sweeper. Beware. A damper only ups the speed of onset a tiny bit more but greatly ups the intensity of the upset beyond human speed and power to react - SPLAT even harsher. i remind the list until a rear rod installed you can not isolate where what is coming from, splashing with another force to show up as a 3rd, so attention is mis directed and never transforms the ride, just incrementally improved, nice as that is.

Hey hobot, I don't push the mk3 beyond its and my age, but being put into a violent tank slap due to hitting a camouflaged bump by the forks inability to cope isn't fun. They (forks) seem to lock up and the rest of the bike and me take over the damping and springing. It's ok if I see the bump and take oviodind action, but that's not the purpose of suspension. My old Ducs are far superior in the front and they are the same age. Graeme

GRM I'm currently living the exact thing you describe on my factory Combat Trixie and it both scares me and works me, just to go normal -as it is- an obsolete cycle out in the real world of road fates. I do not have any close calls nor any hazard upset because I know better than ever kick up heels or go though or over a blind in blind trust w/o conscious reserves and backing off. So you are the one I think is being dangerous, even though I'm a teased icon for it.

I've already been through about every incremental innovation there is and they sorta help but still no real solution to un-expected upsets you can barely recover. If you keep your holier than me attitude just stay stuck in going too fast for unexpected upsets. I know better and never get close calls by my own hand and have never crashed going into turns racer like.

ALL of my really wild stuff slicing dicing road ski jumping, On Purpose, is only on Ms Peel and no one has yet fielded a full linked Combat with hobotor/Fuath Roadholders and fork brace. Most similar set up is Doug MacRae's racer winner.
There may be better forks but none cheaper easier upgrades - that your self described caution - could ever upset to test fork as the limiting handling factor. Serious as free life and death advice form me.

Put the forks back to best factory state and it will behave some better - just like I've done with my current Trixie but still scares me to even ride as fast as some the HD cruisers do in turns. If you do then my respect for your riding wisdom lowers a notch. If I can't get away with much on factory new Combat why does anyone else?

So polish up a turd or do something to forks that makes you like me on Peel and others with Fauths kit, hunting pot holes and washboards at more and more lean and power because its like they just ain't there any more. If ya can read between the lines, bottom line is safer biking reserves and less effort to just get some where.

I rode Trixie this am and still glowing but had 2nd call out which I'd done on Ms Peel but just didn't feel up to the extra attention it takes on a factory C'do.
So I hung tall bewix legs and took the cage.
