Project Cb750RR Ep2 Grafting the VFR Swing Arm.

[@Spydr6684]

Probably an afterthought for you at this point but a 20mm od (or whatever your od needs to be) piece of round stock that you drill a 16mm (or whatever the id of the oem sleeve is) hole in and there you go. But that’s just my take. Awesome looking project either way.

@@Spydr6684 definitely would have been easier to do that. But I’m impatient, a bit cheap and had these parts haha.

[@Spydr6684]

@@motonewengland603 Understandable, I honestly would be the same way. It’s much easier as an outsider to make these observations.

Can’t wait to continue to see how this comes along!

[@lancehenderson4019]

Great job! Do you have the dimensions you turned down that tube/ sleeve? I’m getting ready to start my build later this fall.

Hi what happens to the geometry video and when will it be out ? I am doing the change but I’m a little stuck with it and would like to no how you solved the headache ?.

[@Secucoreinc]

Could I know how you fixed you rear suspension is it a bolt on or did you need to weld a mount for it ? Really nice bike

[@motonewengland603]

@@Secucoreinc it will be a mix of bolts and welding. Still a work in progress, but the plan is to weld on bushing to the frame and weld a mounting plate to the frame under the seat so the R1 shock can mount there.

Brother, with respect. The bits are called insert or tool and you're turning not milling! Best of luck. Cool project.

[@motonewengland603]

You are absolutely right. It’s funny I know these things but you get try talking about it on the fly and it goes out the window. I apologize for the mistakes.

[@juanvargas2776]

​@motonewengland603 no apologies needed! But thanks 🤙🏽

[@krasses_k5859]

Hello! I have a question. The Swing Arm fits into the CB Frame without any processing? And how do you solve the problem with the deflection? Thanks for the Video. Greatings from Germany.

Hello I have the same project with my XS650. I want to put an XJR 1300 swingarm and I have all the parts. I have the same problem, my swingarm pivot bolt is 16mm and the new XJR 1300 swingarm pivot bolt is 20mm. I can drill the frame hole or make a new Bushing like you ?

[@motonewengland603]

@@teurpi28 I wouldnt drill the frame as that’s going to carry part of the stress and I’m not sure how much it would weaken it. I would sleeve your original bolt. Measure the length you need and use some chrome moly tube. Either get the correct inside diameter (16mm) or get as close as you can to the 16mm depending what’s offered and use a lathe and drill the tubing out to 16mm. and then turn the outside of the tube down to 20mm.

Nice work mate!Are all VFR made with same rear swing width? And what year was this swing donor bike?

[@motonewengland603]

VFR swing arms vary a bit. This one is from a 1993 model. If I could do it again I’d go with a later 90s model as they change the mounting system for the rear shock and it would have been easier to convert.

[@plan-bmotos]

Thanks mate! I have keep this in my mind! 😊

[@allencummings6285]

So what year swing arm are you using here. Noticed you mentioned it was almost identical width..

[@walterdemo2895]

I read in search he used a 94 swing arm. Apparently 94-97 are the same and seems like they work on 84-85 vf1000f as well which I maybe try for my build

[@WhyHello-kj9jt]

I'd go the older the better. I ended up with an 03 800 and the frame needed some massaging
