11 inch shocks, 400F
« on: December 14, 2007, 04:40:23 PM »
What can I expect if I put 11 inch shocks on a CB400F?  I am looking for a lower profile vs. going longer over stock and having my backside up in the air.  I like the look of a low profile ride.

Thanks

I LOVE the short shocks I put on my CB500 - the difference is like night and day! The biggest thing is I can now touch the ground flat footed (lol. .  .I'm kinda a small thang) and that does wonders all around - confidence, maneuverability, etc. Appearance wise, they look rad, too. . .similar to stock but dropped it all lower so the tire/rear fender aren't so far apart (looking like a dirt bike or something. .  . lol). Also, they are really firm and tight - like the stock shocks tightened up with the load adjuster thingy two or three notches.


Here is the brand I bought - Forsa, off of eBay, for like $79?



Comparison of old to new (a good two inches shorter or so) (note residual black spray bomb paint job from APO - I'm STILL finding and scrubbing remnants of this madness off, after two years!  >:(



Here was the only "complication". On my bike, the top shock mounting lug has a built in larger 'boss' after the threads that is NOT removable. The new shocks came with a bushing that wouldn't fit it and they wouldn't come out easily.



Here is my jenky assed press custom fabricated, high strength shock tool. (two sockets, long bolt, washers.  . lol). Tightening the bolt pushed the bushing right out, no prob. Then, the new shocks fit like a champ - very tightly.


Also, I didn't lower the front at all, though most would probably tell you to, to retain stock ride dynamics? I liked the look though - barely noticeable and the ride didn't seem to change much. Hope that all helps?   ;D   I sure love mine - one of my all time fave mods I have done to my scoot, yet!!!

Hey Bunny -

Do you know the name of that ebay seller? Any pics of the shocks on the bike (before/after)? 

Thanks.

Sure thing - I guess it was less than 60 days ago because it was still in the 'my eBay' thingy of past won items (jeez louise, I guess I buy a LOT of cycle parts off of the Bay from the looks of it. . .lol. . . .cycle parts and clothes    ;D

Anyways the seller is:
tasclassicmotorsports

(click on name for eBay 'My World' page where on left side are links to current items, eBay store, etc.) They don't seem to have any of them at this time - I found mine when they sold just a few sets of them.

Cycle-Re-Cycle looks to have the same or similar (visually at least) style shorty shocks for $89 - i.e. that chrome 'cap' on top like the OEM instead of being like the 'all spring' shorty shocks I also saw (Redwing brand, I think?)

I will say that these shocks sure seem pretty high quality for the price - good chrome, especially. they might be vintage? (from the looks of the box? - dunno)

I don't have any super recent pictures but when I take some more, I will post a better photo set showing the whole process w/ before and after shots. I have been making too many mods on my bike lately to keep up with pictures - it keeps changing too fast!  lol

lowering the rear of the bike does look good but is a potentially bad thing to do in terms of handling, and steering responsiveness- if you think about it, when the rear is dropped the angle of the forks is made more horizontal, a mild 'chop' if you will-  race bikes have lengthened rear shocks to make the forks more vertical, to increase steering feel.  but if it makes the bike more comfortable and safe to ride maybe shorter shocks are worth it.  I'm not an expert on this but this is how its been explained to me, and I think it makes sense.  experts please chime in on this!  hope that provided something useful, Pat

That's what I was saying that some would tell you to lower the front, to match, so as to not alter the ride 'geometry' or whatever.

Like, you could push the fork tubes up two inches, above the triple tree to compensate for the drop in back (and use that space to mount clip-ons, if you wanted)

I have to say that for me, lowering the back end, or the ride height in general, was seriously a whole another world as far as confidence and even safety went - just because I could touch the ground, and firmly (not on tippie-toes. . .lol).I would REALLY recommend them to other women especially or to anyone a tad short on the inseam.  ;D

I left the front end ride height the same and now it looks a tad chopperish or whatever, but I don't do the twisties much - just ride and like I said, I didn't notice a whole lot of difference in handling and I like the look.

Also, I forgot to mention that I have never bottomed out the new shocks yet, either - like on the fender - railroad tracks and all that and even with a pretty good load on back (running manuals to the Post office for shipping). Then again, I am only like 115# or something so I'm not going to stress ANY shocks too much. . . .lol.
