CB450 shock height
« on: January 25, 2017, 09:06:08 AM »
So I'm wanting to replace the tired and old shocks on my 450 and go with something a little bit higher since I'm tall(6'4") but I don't want to mess with the handling of the frame geometry too much. I've been looking at these Emgo's which people seem to like(other than being a little stiff) and are 335mm height vs the stock 320mm. The website just mentions other bikes than Honda as being compatible but I assume thats because of the odd height but it should install on the bike alright as long as I have the correct diameter bushings yes?
Thanks!

If the bushing size is correct and will fit your existing shock mounts then all you are talking about is 1/2 " difference in shock height. It may change the geometry very slightly, yet I can't see it being enough to make the bike handle in an unsafe manner.
I also don't see it changing the height enough to make any real difference to the ride comfort or height. It is a mid size motorcycle at 450cc's and if you are tall or a big inseam, only a larger bike will probably help you there.
If you are a new rider and want to get some seat time on a smaller lighter bike that is a good strategy, yet in the long term you may end up eventually gravitating to a larger bike with a taller seat height to begin with.
Common sense.....isn't so common!

I had a 750 years ago and I agree with you completely. I'm too tall for the 450. However, I love riding it and wanted it to not feel like my knees are up into my chest. I think increasing the rear ride height would help with that a little bit.

The shocks in your link won't work at all - your 450 has a clevis on the bottom, not an eye.
Similar products are available with a clevis, but there have been reports of interference with the chain guard in some cases.
As for the minimally longer shocks, you won't notice much difference in that context.
However, a pair of twisted rubber bands work as well as stock Honda shocks of that era, so ANY replacements will feel and work better.
I used a pair from an '82 750 DOHC, slightly longer, bolt-up, feel ok (not great, ok).

You can bite the bullet and order some Progressive shocks, which will fit perfectly and work GREAT.
Maybe partially because your wallet will be substantially lighter...........

You were correct, I didn't look carefully at those shocks and its a good thing I didn't order yet! What about these? Here is what I'm looking at: http://4into1.com/emgo-performance-black-chrome-shocks-eye-clevis-330mm-13-cb350f-cb400f-cb450-cb550-cb750/

Or I could go with adjustable but I'm not sure how well it would ride at 330mm: http://4into1.com/black-chrome-adjustable-remote-reservoir-shocks-eye-to-clevis-320-330mm/

Or....spend twice the amount and go with Hagon's from Dave Quinn.
