Title: Will a CB500 BUMPER, REAR fit a CB550F2?
Post by: deltarider on November 14, 2023, 03:57:16 PM
I forward a question asked in the German forum: Will a CB500 BUMPER, REAR (PN: 84101-323-671) also fit a CB550F2?

It will fit but the light bracket holes may be different, especially in different coutries.
Have said that 500 rear mudguards are worth a fortune

The 550K3 will also fit except the 550K3 rear guard has the top bolts embedded into the guard unlike the 500/550F ones which had the bolts passing through the frame crossmember. The 550K3 had studs on that did the same thing except you just used 2 nuts instead of 2 bolts. There are 3 hole and 4 hole versions of both, as Bryan says it depends on what he has already, if he has the other type he'd need to change the rear light bracket at the same time.

If what you are talking about is the grab rail and not the mudguard the UK 500 never had one and the US ones have different sized blinker mounts,rubbers and sleeves. Also seat lengths are different so that may foul as well

I've made it a habit to use 'Hondaspeak' whenever I talk OEM parts to avoid any misunderstanding. (I wish more would have that habit). That's why I said BUMPER, REAR which is how that part is exactly described in the CB500 Parts Lists. Yes, it's a grabrail. The grabrail UK CB500s never had. You overthere had the poorman's edition  ;). But now that all models surface anywhere, I thought it safe to also ask here.

A bumper over here is a mudguard not a grab rail. Why Honda would call that a bumper is beyond me, it's not protecting anything really.

The grab rail off a 500 may fit but the 550F has a slightly longer seat so even if it did fit, the passenger may not be able to get their fingers around it. The 550F grabrail fits the 500 quite nicely.

As Bryan says though, it's really difficult to find the indicator mounts to fit the 550F grabrail.

Not quite true as the genuine UK versions of most Honda models particular the CB500K0, CB750K0 and CB250K0 now command a much higher price than those imported from any other country. (OK they all came from Japan anyway  :) ) So we may have had in your opinion the 'poor man's version' when they were new but not now. Anyway, a lot of the UK differences were for practicality in our climate rather than cost cutting. Like the deeply valanced mudguards (sorry fenders ) on some models like the CB250/350K series.

Interestingly, Honda did use the word 'mudguard' on some models but for the 'fender' but the little rubber flap attached to the rear mudguard.

@ Oddjob Ofcourse I realise the terms in the Parts List are sometimes odd, but - once again - to avoid any misunderstanding, I always represent the original term, often accompanied by the PN and to make it even clearer it's Hondaspeak, I always write them in CAPITALS font size 8pt.
@ Ash Don't you agree everything in the UK becomes more and more valuable just by the pound sinking and sinking deeper? Can't blame that on me; blame it on Cambridge Analytica. ;)

Nothing to do with that whatsoever...in fact pre all of the #@%$ and energy crisis, Covid, wars etc troubles. the UK bikes were at more of a premium than they are now. Trigger and Woodside on here both sold CB500K0 UK bikes for £10k  .. never seen a 500/4 from other markets achieve anything near that.

You - must - be - jo - king... with that... that... thing?! A grip you can buy in just any hardware store. And there aren't even two of them, to offer at least some symmetry. Compare that to the endless, elegant, grab rail on the international deluxe version of the CB500. Look how nicely it follows and accentuates the line of the seat. It's... royal... sexy too; your hand can glide over it, fiddle it all over. Female passengers with inquisitive fingers like that, you know.
Practical too. I've seen this wonderful rail accomodate not to big leather bags... on both sides, mind you, where as that... that thing... words fail me... the horror, the horror!!

Each to his own Delta, personaly i think the grab bar is an abomination purely for pillion passengers to hold onto and i dont do those

It's not as nice as the 550F one, far too low as well, passengers would have their fingers up against the mudguard. The 550F one fits the 500 great, perfect in fact, plus it holds the indicators as well making them easier to see.

No, no, on the contrary, both seat and grabrail are in my - as always - humble opinion the most elegant of the CB500/550 series. The CB550F one is far to 'hooked upwards'. The 84101-323-671 grabrail is more or less a continuation of that swift striping only the K2 tanks have, where as the paint scheme of previous models... but maybe I'd better be silent... All I can say, is that the old paint scheme is as blunt as that hardware shop grip. ;)

Bryan, in all honesty, all my passengers have used it and were able to vary the position of their hands to their liking.
But - wait a minute - now I understand why there is so much talk in this forum about that silly strip (hoop?) halfway the seat. Most of us here in Europe took it of rightaway - as a useless and abundant extra that spoils the looks of the seat, but ofcourse UK passengers depend on it, as... there's nothing else! 
BTW using that strip, good luck finding room for your hands between the two of you.
Not good for handling the bike either. Whenever I had a passenger, my instruction always has been: hold your body as close to my back as possible and move with me, as if we are deeply in love, in a socalled 'uniform movement'. It's exactly there, where the grabrail serves so perfectly as the passenger can more or less press her - often lovely - body to my manly back, assuring our 'unisync movement'. I will not go in further detail, as there may be women and children present, but a good listener only needs half a word...
Where our passengers can react to acceleration and deceleration adequately, your passengers, clinging on that silly strip, will react like a harmonica and possibly slide all over place, with the risk to come dangling to the side of the bike. I hope we can all agree that that does not particularly favour the handling of your bike. Worst scenario is when passenger will come to dangle on the righthand side of your bike where there is - oh horror - not even that minimal grip.
In contrast the position two-up we are used to overhere, is also best for aerodynamics. No turbulence in between the rider's back and the passenger's front like you have, due to the gap caused by the passenger's fists at that strip. Alas, no lovely body warming your back, but only her cold knuckles painfully poking in your loins.
But there's hope for you guys. At CMSNL you can order the 84101-323-671, the beautiful Italian made repro, which is an exact copy, but in much better quality than the OEM. You can then remove that horrible grip you have now, and may use it on the door of your garden shed, garagedoor, barn, whatever. But I cannot blame you, if you don't want to see it anymore and will throw it away as far as possible. Success!

Delta, you missed my main point I DONT DO PASSENGERS therefore dont need one with its floppy rubber mounted indicators.

I think your imagination is going into overdrive there DR.

None of my passengers, male or female has EVER used the seat strap, I often wondered why Honda fitted it in the first place TBH, I think it's more aesthetic than functional, like the rear fins on American cars of the 50s. We used to just ask the female passengers to put their arms around our waist or if you were a fatty grab a hold of some flab  :D

As for the Italian made grab rail, must admit to asking the manufacturers of that part many years ago now to consider making one for the 500, they were making others and I thought it would be within their skill set to make one for the 500/550. They sell them direct on their website for oddly enough more than people like Andy Cepok sell them for. I found their site by accident after searching for the gear selector forks for the 500, which they also make and which I bought a full set of last year. https://www.gbmotosport.it/en/honda.html

The 500K1 rear indicators are also rubber mounted Bryan, just not as bad as the 550 ones, although the 550 ones stick out more so are easier to see.

True Ken but the ones on the grab rails always seem to droop more to me, building for me will be uk spec building to sell will be what i have!

Honda for sure overdid this dampening rubber blocks thing at the rear indicators. Vibrations there - if any - are so minor that I can't imagine it will affect the bulbs life expectancy. I refused to use them and improvised to cut my own of a thin sheet of rubber. Works great and looks better than the original.
