Um... In one word... No...

I think we have a small misunderstanding here... The only things you need or have use for from an RC51 is the swing arm, brake caliper and mount... And possibly the rear wheel if you choose that vs a CBR wheel...

The VTR and RC51 is monumentally different in how the linkages are setup... The VTR has a classic dog-bone ie beefy alu chunk with one bolt at each end (although bolted to the engine, not a subframe... Somewhat unusual) and a lower link of two rather large (in comparison) triangles welded together at one point, bolted to the bottom of the swingarm...

The RC51 has an dog bone that is a bit unusual, in OEM form those two legs are fixed length, the Kyle/soupy version is adjustable, and the triangular link is basically a chunk sitting inside outer mount ears... That triangle is also in comparison to the VTR smaller and has a smaller ratio... combined with the dog bone being longer than the VTR's and a much, much lighter spring rate in the shock, you get a suspension that behaves a lot differently...

So that dog bone will not bolt to the engine end of the VTR unless you completely rebuild that... Also the VTR dog bone is asymmetrical, not the same width at both bolts, and the RC is symmetrical... And even if you do get all that to line up, you still need to come up with a custom link as the RC51 shock comes with a clevis bottom end, not an ear as the VTR's and most other shocks...

That doesn't mean however the idea behind that dog bone isn't useful... There are two ways of getting the swing arm to work with the VTR suspension... Or rather three... One is having the mount on the swing arm at the same relative position as on the OEM swing... Since that is impossible unless you cut the arm to pieces and weld it up again, that's a no go...

The other two is to change the length of either the dog bone or the shock and figuring out a working geometry... Or both, but then you end up with a mess as far as mathematics go... To many variables...

Since I was going to change the shock anyway, I choose to make that adjustable and keep the stock dogbone... Then I worked out the geometrics to be reasonably close to stock travel and loading on the shock (since then I could have Jamie valve it as it was going into a stock VTR... Again, less variables...)

Then since the swing arm has two outer ears as it is, you can either weld on it like I did on my bike and have an easier time making custom triangle plates for the link... Or make a triangle link that is plates at two points and a chunk in one... I considered that to be more work... And I did it the second time based on the fact that I had then already worked out and tested the geometry... And that meant I knew it would work, and I wouldn't have to make several tests...

I'm not saying my way of doing this is the only way... I'm actually quite certain there are several others... And quite possibly there is a better way than mine... But I'm saying there is NO way I know of to bolt existing pieces together... Believe my I tried very hard to find one... The only way to match up the pieces is to make at least one of them from scratch to make up for the fact that you cant bolt two outer ears together, you need one to be an inner piece...

And just about any way you do that starts with breaking out a calculator and a calculus text book and working through a couple of pages of equations... I have already done that... You are all welcome to use the result, but I'm not going to give anyone here ALL the details... That's not because I'm "holding out"... That's more my equivalent to a childproof box for the sharp knifes in the kitchen... If you can figure out the details for your self you can try it out... If you can't you probably shouldn't mess with the stuff... Because it can most definitely kill you...

Sorry if this sounds harsh or condescending in any way... It's not intended that way in the least... It's just that I don't want to be responsible for anyone else getting hurt...
