Hi all,
I am going to convert my MC18 R2J with a R5K swingarm and just getting some parts from Jamie (vzzzbuxt ) including the rear caliper, caliper mount and the torque arm.
Question is, neither Jamie or I can work out what the front of the toque arm attaches to as the rear of the bike he is breaking was stripped when he got it. Had a look at the parts manual and can't see it on there either.
Anyone with a R5K got a photo, or point me to the right place on the parts manual??
Cheers Ade

have a look at this mate. looks like attached to subframe mount or rear engine mount or summit???!!!????

ill try to fathom it out later

The torque arm fits to the inside of the frame. You can see the bolt hole in thet pic, its just above the pivot bolt.
If the R2 frame is like the MC16, it has webbing on the inside and would need stripping to gring out the web and make up a spacer.
I ended up selling my R5 arm and fitting a R2 arm to my 16 because of this problem.

Ah ha,
Now I see Jeff
Jesus, looks like its gona be one of them there simple jobs
Don't fancy drilling the frame, maybe I can sort something else, hopefully!!

Cheers anyway

does the torque arm need to be there if im putting rk5 swingarm on mc16?looked at my k4 g###750 today it hasn't got one

Because there is no lug on the R5K swingarm there is no where to put a torque arm so yes it must be mounted to the frame. If you use an R2J arm like Jeff did then there are already mount for the caliper bracket (a bit like on your gsxr)

so all the torque arm does is hold the caliper bracket then?

Yes.

If you use an R2J arm like Jeff did.Too easy!
so i have 2 options either drill frame of weld a lug on me swingarm.
No worries for me to do either

Right!
After stripping out 16 swingarm of 16 frame tonight and fitting RK5 swingarm in it's place a couple of things i discovered,it's far easier in my opinion if your doing RK5 swingarm conversion on either an mc16 or R2J to weld similar rear brake caliper lug on swingarm!To start grinding away at the webbing inside frame is not a good idea
A problem you have if like me your modding a 16 the rear wheel spindle is 17mm compared to 20mm rk5,i'm guessing r2j is 20mm also,so i can either get r2j bracket or machine 16 bracket out to 20mm i reckon theres enough meat there to do this without bracket breaking and then at least i'll be able to use my 16 rear caliper as disc size is the same
cheers Rob.

But i've got 1 NSR !!

Like i said "exellent taste"

Kimmy,I thought the 18 was for your missus mate
Could you let me know rear wheel spindle diameter. in parts manual r2j and 16 caliper and carrier are the same

Your rite it is the missus's but do you think she looks after it !!
May aswell be mine..
actually i set up this profile up for the missus so she could start learning about her bike, but she is not so keen on the maintanence side of things !!! I'll have to set up my own profile !!
Unfortunatly i don't have anything to measure with ..
