Hi

madmaximum are you talking about a CBR600 shock? - if so which year / model

cheers

Hi Frog.

I'm not 100% certain, but I think it was a 1992 CBR600.

How'd that shock work out for you?

madmaximum · 11-29-2008, 04:01 PM

It worked ok, but getting the R1 shock in there would have been better.

How about the suspension travel? Much improvement? What do you think of the ride?

Did a little checking and came up with this list of possible rear shock candidates for our DS's:

These shocks should be approx. the right length anyway. Which ones would actually work remains to be seen. :?

The cbr shock gave me about an extra inch of travel, and the biggest difference I noticed was over washboard bumps, it was much better.

That's a big plus!

Hoping that this Montesa shock will help, too. Hasn't arrived, yet.

The Marzocchi shock arrived yesterday. Had to crank down the preload almost all the way to get it to drop to 11.5 inches for the stock linkage and it was pretty much a simple bolt on. Mounted up inverted fine putting the clevis on the bottom with a little room to spare.

The air precharge was flat, and with only the spring i had about 3 inches of sag and 3+ inches of travel beyond that so the rear bottomed very easily. After i charged it with about 100-120psi there was barely 2 inches of sag and it wouldn't bottom out. The travel appears to be 6" maybe a little more.

This shock is a little longer and with the clevis it allows the suspension to extend up another 1/2" or so. Which should give about 7" total travel- theoretically anyway.

The difference was truly amazing both on the road and the trail. It just soaks up everything. Plush as can be and yet never bottoming out on light trail riding. Road about 40-50 miles in the rather cool air. It's a different bike!

Wayne's result sounds great

I've ordered a second hand CBR600 shock - fingers crossed it will give similar good results............
I'll post when it's fitted

Anyone tried a fastace shock yet?

elroyjetsn · 12-09-2008, 12:05 AM

Frog,

Sounds like that shock should give you alot more suspension travel. For a much heavier bike, though.

You should be able to adjust the N2 charge to compensate a lot. Some of those have a height adjustment, too.

May turn out to be a fine upgrade. Cheap and abundant on Ebay, that's for sure.

I think the new Shineray 250 uses a Fastace.

Hi

Have fitted a cbr600 shock - the type without the remore reservoir. This is not a direct bolt on to a GY-5 - but I only needed to weld on some thick 10mm washers over the standard 12mm mount holes.
The shock is 12mm longer than standard (292mm) but there is no need to modify the mounts other than as above - seat height is now a little higher.

Result is good for on road use - about 4 inches of travel that is well damped (unlike the standard shock!). The limitation is the stroke on the shock not the linkages.

However 4 inches is not what I had hoped for as I do green lane my bike - still have my eyes open for an alternative shock - Maybe a fastace ......

That's gonna be a problem with the road bike shocks. They can get by with 4" of travel.

But, almost all of the dirt bike shocks are way too long. :(

Fastace makes 11 and 11.5" shocks with lots of travel??? Seems like a possibility.

Frog · 12-28-2008, 11:10 AM

Hi Wayne

how did you mount the clevis on the montessa shock you used? I can not figure out how to use a shock with a clevis type mount and still keep a working bearing on our mounts........ :?

If this is easy to do then the early bandit 600 shock looks to be an option - looks to have a reasonably long stroke 8O

cheers

elroyjetsn · 12-29-2008, 12:59 PM

The Montesa wasn't a problem since the clevis was a little narrower than the original shock's end. The shock was shipped with the correct mounting bolts and nuts, too.

The top mount is also narrower. Eventually, i'll be adding spacers to keep the shock centered in the mounts.
