Can you use a R6 shock with the RGV swingarm? Also what is the best rear wheel to use with this swinger?

Not sure about the R6 shock since I don't have one, I did the RGV swingarm conversion acouple months a go for a guy in Cal. and we
used the SV650 shock. Best wheel to use is the RGV wheel with brake
and calipher bracket everything fits, save's on allot of machining trying
to fit a bunch of mismatched parts.

T. Rex,

Conversions pretty easy, a couple of adapter plates that mount to the RZ
frame,6 spacers and doing the bearings.The VJ22 swingarm is a couple
mm's shorter then the RZ arm so it fit's inside the frame with no mod's
to the pivot tube. As long as your shock has the same bottom attachment
as the stock RGV shock it should work,oh, you also have to make new
dog bones if you use the adapter plates,if you extend the lower frame
bracket then you should be able to use the stock RGV parts. Using the
RGV rear wheel with the stock brake parts will save allot of extra work.
On the one I did for George he wanted to use the NSR 5 sproke wheel,
it works but required machining the brake calipher bracket to about half
the thickness and making wheel spacers for both sides to center the
wheel in the swingarm. If you use the drawings that were posted on this
site a few months ago the patterns for the whole conversion are shown.
There's 2 different plate designs, 1 fixed,1 ajustable, I made the ajustable
for George's, for what little it moves, it's not worth it. Also the drawings
show 3 different options for doing the pivot bearings, I came up with a
different way that was much simpler. If you use the pattern for the
adapter plates take the meassurement and make your own pattern even
though the drawing shows a 1-1 scale . I did this and the pattern is around
a 1/4" larger then the drawing, but the diamensions are all dead on.

Thank you Steve.I'm just thinking about what,if anything to do to my RZ.I am spoiled by the rock solid stability of my '04 Tuono and it makes the RZ feel nervous.There are so many set ups I just need lots of info.Oh do you know if a FZ750 swinger is a usable item?Thanks again.

I've only seen the FZ arm installed on the bike but can't really think
of any reason it couldn't be used. So far of the conversions I've done
I think fitting the RZ500 arm to the RZ350 has been the most time
consuming with the most modifing required.

R6 shock won't work with the RGV arm, the reservoir hits the arm before you even get to normal ride height.

Does anyone have a link to these drawings? I have been searching but can't find them

Here is the project page (not mine): http://www.rd350ypvs.goddeloos.nl/Projects.htm
There are links to the drawings with the pictures or a link at the bottom with all the drawings together.

i used the rgv shock but i chopped the rz top shock mount out and fabbed a new one so as to use the original oil tank and battery mount minus the air box,i fitted uni filters instead. after i did it i thought a bit about it and said if i altered the next one the ride height could be whatever you wanted....i used stock rgv dogbones :smt001

T, just remember that your RZ will never be like your Tuno. With all of the upgrades I have done on mine, it is still a "flex flier' as SCREAMER says.

With the FZ600 arm on the rear, I still think it flexes too much. The RGV arm will probably be much better. But then you still have the frame...

Steve

You could modify the frame to make it more rigid. This is what I'm doing with my frame. The tubes are in PVC on the picture but wil be in steel once the frame is welded. I have the frame at the welding shop right now and don't have pictures of how it looks when the welding is done.

I hope tho get the frame back this weekend.

Picobello,

What you've just shown, I've often thought is a great idea. How hard will it be to get the engine out?

Most of the bikes that I've seen with a similar frame (Duke's, Triumphs, etc) look to have the engine hang from the top of the frame and there is no cradle at the bottom - that allows the engine to drop out of the frame - much like the big box aluminum ones.[/quote]

The engine can slide in and out the frame if you leave the carb's off:
