CB350 Dual Disc For Dummys?

15765 Views 49 Replies 13 Participants Last post by  Classic250
I have searched here and many other places for a how to guide to putting a dual disc setup on a cb350, but I have had no luck. I know this is probably a fairly common upgrade for these bikes but I have no idea exactly what the process is or what parts are required. Most of the posts I have read say you can use cb550 triple trees/forks? but since they didn't come with dual discs I still don't understand how they work.

Can anyone lay it out for me? Go ahead and assume I'm a dumbass (I'm sure you will anyway). Or point me to a post where my question has already been answered.

Thanks!

There are a couple of ways of doing it
1. fit a second left fork leg to right side. Looks a bit odd as one caliper is in front and one behind fork leg
2. fit different forks with dual disc capabilities.(Any of larger model CB's, 450, 500,550)
3. fit a completely different front end (Suzuki Katana is eay with minimal welding)
Options 2&3 are best as the stock 33mm forks are a bit flimsy.
Honda 35mm forks work OK but are a bit heavy
Katana forks are 41mm and about same or lighter than stock forks
There are other forks that can be fitted but so far the stock or Katana are all I've done
I've posted pic previously of CB350 drum in Katana 600 forks on CB360
but here it is again

The blue forks are 2002 GSXR750, same length as stock Honda forks

I believe you can't have too much brake.
You can learn to use it if it's got plenty of 'stop' but you just go slower if there isn't enough (which is why I'm fitting drum to modified 360 :D)

Personally, I find CB360 disc brakes barely adequate, could possibly be my riding style though ;)
