CB450 1971 remove the front brake switch... any brake gain?

[loka]

you can't cut the tubes, there is a channel at the bottom which corresponds to the valve and the top is threaded for your caps.

I think forks by frank may be able to help or maybe cyclex, they offer different lengths. Some 750 forks may work just verify the channel at the bottom is at the same position on your 450 tubes

you can slide the top of the tubes through the triples. you will see that done on lots of bikes around here. it is also possible to shorten the tubes by adding spacers and some other mods. search for fork shortening or something like that. i think Woody shortened his

Ok then if I undersand correctly... I can make a fork work my bike as long as its a 35mm?

Will a gl1000 fork be a good upgrade? Or more a CB750f?

Thanks for your help guys!!!

And are you telling me that the CB900F 07 Honda hornet caliper would fit on my bike after the GL1000 upgrade? I mean... when the same stock style Line, master and front disk??!?!?!?! ;D

No. They are not a direct swap, but can be made to fit with an adapter.

As swagger has suggested, your best bet, and easiest swap, is the GL forks with the dual piston calipers. I'm not too sure what you plan to do regarding the disk, or even if the GL rotor will fit your wheel, so I can't advise there. An easy solution would be to replace your wheel with the spoked GL unit and be done with it, giving you instant access to a twin disk brake front end.

To keep things simple, people are suggesting forks that will fit into your triple trees without the need to bore them larger, or swap them out. Both these things are commonly done to increase options for larger diameter forks.

This can be as simple or as complicated as you feel comfortable with

cheers

Ok thanks!

I was more thinking about the cb750f fork as its more sporty than the gl1000. what's you think? And more chance that it would fit bolt on right?

UP Any advice for the handling. cb750f or gl1000 fork?

Sorry Joe, been gone a few days....

Go look for a good servicable GL1000 front end. Heck, you may well be able to score one complete with the wheel too.
Cool because it'll have a shouldered aluminum rim and all the parts will line up correctly. As for calipers....as noted, ANYTHING can be fitted up with enough machine work, but the 750f/900f (I'm talking about 80 to 84-ish here, not 2007) twin piston calipers will bolt up and should be fine with the GL discs.

As for sportier bits....that's pretty easy to address. Neither will be remarkable as is, and probably pretty mushy in truth.
What you get though is a solid foundation to build from. Once you ahve the front end hung off the bike look for firmer aftermarket springs and a pair of emulators. If you to to racetech.com you can find just what you're looking for.
I'd take a look, but contact them directly and chat a bit with one of their staff members. They all want your bike to be awesome and if you're using their parts they'll go the extra distance to make sure you get what will be best.

Cool thanks!

But why are you going with the GL1000 over the CB750F fork? Is there a reason?

I already have my tires for my cb450 wheel so I think I'll buy just the fork and calipper.

 

[Swagger]

The Gl set is likely to be a little less expensive and will perform the same with similar mods.

No biggie man, sounds like you're on the right path....

Hey joevirus

The fork swap is legit, but if all you're looking for an improvement in braking I suggest just going upgrading to a stainless steel brake line. I ditched the oem switch and replaced it with a banjo bolt switch and braided line and its a HUGE improvement.

Hey thanks for the tips but actualy I might have to change my fork because my fork have rust on the tube... that's why I was king of looking into my options.

Think I'll go with this: Cb750f fork: 75$ Cb750f caliper: 20$ cb500t or cx500 tank, steel line straight: 50$ banjo bolt: 20$ (Already ordered) .
