WTB 750 Sport Swingarm

[Finnpaso]

I also like that Gerhard's foto of that "MHR" replica with new fairings, fuel tank, wheels, brakes, etc. etc... but i prefer allways MORE to ORIGINAL... . For me, its not so important, how Paso should look, as its never such collectable bike, as REAL MHR, TT1, Santa Monica, Montjuich, etc are...

There are in big world huge amount of "replicas"(especially from these Ducati modells) but ONLY few original what coast alot of money....

For someone only "looking" means, but for someone it have to be original.. With new fairing painting You can change alot that "looking", but....

Hi Everyone

I just thought you guys may be interested in my tale of woe with regards to my long search for a 750 Sport/F1 swingarm.

Have been constantly searching eBay in the vain hope of stumbling across a Verlicchi swingarm for the TT1 bike I am am building.

Anyway, imagine my surprise when one pops up on Aussie eBay........and total amazement when I find that the seller lives in the same city (Melbourne) as me!.

I checked every day for the status of the expected bidding war......no bidding war ensued and I win the auction for the min bid of $400 AUD.......I can't tell you how pleased I was

I emailed the guy to arrange payment and pickup but no reply.......call him the next day only for him to tell me he sold it to someone for $500 AUD an hour before the auction ended........not happy!

This is a long term project so I live in hope another one will pop up.......and in the meantime I do have a Verlicchi swingarm for the later series engine I can adapt to fit if I have to.

Hi mate,

This may be a "red herring" but here goes.

I have an aluminium swingarm from one of the first 1200 or so 1991 750SS bikes. I was keeping it for a worthy cause but your project bike sounds like one.

These first few 750SS bike had a narrower case at the pivot than the 900 and all later 600/750 SS bikes (no needle bearings), and was the only version of the 750 that came with a dry clutch like the Paso (with the clutch slave cylinder in the RHS clutch cover). The arm is the same outer width at the rear wheel as the later SS ones but has a narrower inner width. It has aluminium spacer tubes integral at the pivot end to line it all up with the narrower cases. Maybe it was taken from leftoever 750Sport parts?

I wonder if it with fit? The good news is it will take a 17 inch wheel.

Maybe if you send the width measurement you need at the cases I can check? I'll dig it out and send a photo.

Cheers,

Mick

micklm......thanks so much for the kind offer......the width at the case end is 155mm.......and would love a pic if you have one.

persempre907.......my sentiments exactly but it is the first bad experience with using ebay that I have had in 10yrs.......just so annoying it had to happen with such a hard to find part.

Thanks guys

Mate,

I'll have a look tomorrow at the swingarm and get a photo off to you.

The width of the cases at the pivot on the engine it came off is 150mm so we may be on to a winner here.

cheers,

Mick

Mate,

The swingarm I have is about 155mm between the pivot ends and takes a 28mm OD pivot (which I do have with the arm, and is much larger than later SS bikes which had the needls bearings in the case). See photos:

No cracks in any welds than I can see, but I've not cleaned it and looked hard yet.

Let me know if it would be of use and we can sort out arrangements offline.

Wow, that looks exactly like the later model SS swingarm on the 900, except that it takes a bigger pivot pin, and the space between them is much narrower. Not as beautiful as the Verlichi part, but it should work just fine. I would think that if you really needed to, you could use an SS swingarm, bore out the pivot pin holes to hold the larger pin, and add some spacers to fill the gap. Machining of course is the trick. How to get those two holes aligned so that the look right at eachother? A good machinist is needed.

I have a 750 Sport that a previous owner had adapted the steel SS swingarm to it. They cut off the two forward sections, bored them, then welded them back on. I assume they used the pivot pin to align the two pieces while welding to ensure alignment.

Cheers,
