Handed down 1984 CB700SC
« on: February 11, 2017, 03:45:23 PM »
About 15 years ago (I was 15 at the time), I traveled with the family to visit my grandparents. While there, my grandfather taught me how to ride a motorcycle for the first time. That occasion plus 1 or 2 more were the only times seeing him until the most recent visit. He isn't doing well and I prepared for what was probably the last time I'd get to see him. He was a little out of it, but he wanted to make one thing clear: that I took the Nighthawk home with me. So, the very bike that I learned to ride on was given to me, and I had no idea he still had the thing. Anyways, he's the second owner and it has a mere 12,000 miles on it. Enjoy!

Thanks for sharing your story.
It is inspiring, so glad your grandfather got to give it to a person that will cherish it.
A Corbin seat, too.  But I'd ditch those red had grips.

Ride safely,

Looks to be in fantastic condition -- congratulations.
Make sure you check the age on those tyres.  The front looks like a Metzler; don't recognise the rear.  Anything older than 4-5 years should be replaced, regardless of the amount of tread.

Yes I thought about the tires. They don't feel like rubbery rubber, but dry plastic-y rubber. Question is, can I put wider tires on the stock wheels? How wide can I go front and back?

I've gone with 150s on the rear and have been happy with it. Don't recall if the 700S takes the same stock sizes as my 03 750.

You can check the date of manufacture using the DOT code stamped on one side.  There are decoders online.
You're pretty limited as far as tyre choice goes with the 700S.  You don't get to do things like pick something fatter -- you get what's available.  I had Shinkos on mine but didn't like them; the Pirelli Sport Demons on it now are far better.  I think there's still a Metzler option as well.

   wlcm1  Great  Grandpa and out come for the NH. OEM grips are great, what state are U in ?  I can't find anyone here with a NH to ride with. I'm sure you will take great care of her.

Other than lubing the drive line assembly there pretty much gas and go for maintenance.  How many miles does it have ?

I'm running the GT - 501's. There getting old so this year I need to burn em up but there great sticky tires.

I went with Pro Grip 701s, great improvement on feel/vibration. I'm in southwest Ohio (Dayton) and haven't seen any NHs in town. I have a couple friends with Harleys and/or crotch rockets that I occasionally ride with. For tires I went with a 120/150 combo Pirelli Sports. great tire!

As far a "lubing the driveline" I've replaced wheel bearings and checked the rear ring/pinion oil. what else would you recommend doing?

it's got 13k miles on it.

Get a book, someone on the old site had the PDF ?   I'd say the drive line, uses that special grease.

The PDF is available from various sources online.


Along with the hypoid gear oil in the case on the rear wheel, there is a damping cup on the tail end of the driveshaft that needs to be filled with oil.  Only way to do this is to take the driveshaft out, but that's not a big deal once you have the rear wheel off.  You should also grease the splines at the front end of the shaft while you're doing that.

I bought a red/black/orange 1986 a couple of years ago and considered a Corbin seat.  However from the pictures of Corbin seats on several 700s bikes I had seen it appeared the area where the rider sat was heavily dished out so that the rider sat much lower.  This seat looks much more to my liking.  Does anyone know if this is the standard configuration Corbin or if Corbin made it flatter than normal?
