I've always wanted to do a big metric twin build...couldn't find one for free, though, so I'm settling for a 750 haha. Still makes 50lbs of torque everywhere so gonna be a fun little build I bet. I'm not 100% certain where I want to go with it but I expect it to be similar to my CX500 build. What I have on hand so far is a 675R front end and a Gen 4 VFR750 swingarm/wheel.

My concerns are how fat the tank is and finding a good shock.

So now I have TWO! One is going to be a build, the other is going to be for miscelaneous parts and the motor itself is going to go into my Roketa buggy.



My initial plan was to set it up with a VFR swingarm. I'm going to using either an R6 front end or a 675R setup and the VFR arm was going to make finding a nice match on the back EASY, but I couldn't sort out making the VFR arm work properly. I'm going with this VT600 braced swingarm instead!



This arm is about an inch shorter than the 750 arm which suits me just fine, I want the wheelbase a bit shorter anyway. Major issue I'm going to have is mounting. I'm going to take a stab at mounting the 600 arm in the 750 frame but I fully expect to have to chop the two apart and weld them together in a somewhat hybrid configuration.







I'll have a video up later today starting the process. I'm going to try and commit to doing at least 30 minutes a week on the bike until it's done.

So the swingarm flairs out on the RIGHT side for some reason. There's no way the sprocket would align with the thing. I flipped it over and now it all meshes together but I got to start from scratch sorting out the shock mount. Will probably end up being along the same lines as my CX build, but I'll be using an R6 or R1 shock with a MUCH heavier spring.

Whole album for the interested

Well the tube swingarm just won't clear anything at all...sucks, I really wanted to use that. Risks of trying new things! I think I'm going to have to make a swingarm to get what I want.

Right now wheelbase is 63 inches and I want it does to around 58~59 inches. Plus the chain contacts the top of the arm so I'm got to modify things at the very least. Gonna have to cut and weld!

Okay so back to the original swingarm. I ended up notching and bending it to get it low enough to clear the chain at the right height I wanted...which may add some complications later but I'll sort that out when I get there. I got the arm braced and true, setting up the shock now. I'm going to use an R6 shock because I know they work sideways...the R6 and R1 shocks are popular with bikes like the 650 ninjas...I'd rather use my CBR954RR shock but I don't know if it'll work properly laying on it's side.

Still trying to figure out a tank and a seat. Odds are I'm going to run the same cheap tank and seat combo I have on my CX500. It's cheap and under $100 for the pair. Trying to find tanks that'll fit this thing neatly has been problematic. Same issue I had finding tanks for my GL project. Not a lot of good options, and the good options are $$$$.

...and this is the final stance:






This bike has also been probably the luckiest fork swap in the world. Stem pressed out of the Honda triples and directly into the Triumph triples haha



Fork swap video (not live probably until about 6:45am CST)



My new tank, seat, bar controls, and a few other small bits should be here over the next week.

Thanks I hope it pans out as neat as I have in my mind! Trying to find a rear wheel before I go too much further...I need to find someone with a 2nd~4th gen R1 to measure the inside of their swingarm...maybe I could get an R1 setup back there! I got 11" of room.

wow I found some guy who's parting out an '05 R1 and measured the swingarm for me...under 10". He needs a set of '05-era forks for a Virago he's building, says he'd do a trade for all the bits I need for a set of serviceable forks. Might have to snoop around for a set of forks :D

You know what pisses off a bunch of classic cafe "racers"? This build lol...one guy has gone so far as to make an angry youtube video describing how my rear suspension has ruined his life.
