Seca rear shock replacement

My 650 seca has a pair od koni special D, 7610p-1412, 4 setting adjustable shocks. The rods have rust pitting, seals ok at the moment but I guess that won't last long. So the question is, whate is available as replacement or upgrade at reasonable cost? I would like double adjustable, but it all comes at a cost I guess.
Suggestions?

 

Came across this site :-

 

IKON were (are?) one of the big aftermarket upgrades, so prepare to spend some money to get something equivalent or better.

Progressive brand has been well-liked by several of our more respected members.
KYB is another brand that I happen to like, and they have a wide selection of options at whatever cost you want to pay.
There is also the choice of buying some used stockers, though you'll want to ask about the mileage of the bike they came from.

 

The issue with used stockers - or aftermarket for that matter, is condition is everything, and you have to eyeball them.

 

YSS is another brand that has good reviews, and they have several choices in addition to making reasonably priced custom sets.
I haven't owned a set of their shocks, but the few bikes I've ridden with them on were comfortable and handled well.

 

if you are seriously minted, Fournale are THE best, and lightest option available.....I ran two sets, in the early 90's.........sadly, they cost about 1/2 what our XJ's are worth!!!

 

If we're going all-in, may as well order custom valved and sprung Öhlins.

 

Probably still cheaper than Fournale !!!!

 

That all depends on what you want. Öhlins run anywhere from $500 each for standard street bikes up to around $10K each for custom racing shocks. Stupid money IMO.

 

IKON is KONI (rearranged!)....Ikon bought the motorcycle shocks side of the original Koni company.......

 

Well I just figured out CHACAL is French for Charles or JACKAL ...was watching one of my Favorite movies Day of the jackal from 1973 and that is a line in the movie.

 

Originally the word is Turkish. Languages are fun.

 

Actually, it's CHArles CALthrop.............

 

Had I not watched movie and looking at the Forum at same time would not have paid much attention .. lol

 

Ikon shocks say their kit is rebuildable, but don't offer anything online. I'll send them an email to see if they can do a replacement rod and seals.

 

IKON 7610 type on my xj and 1 other bike. I like the damping adjustment factor.

 

Basic Hagon's available from 150 GBP ish.. see here..

Yeah, they're high on the list of alternatives

 

Got an answer from Ikon shocks - pretty much what I expected:
Thank you.
Unfortunately the rods only come as assemblies with the internals attached so very expensive & you still have a pair of very old units.
Buying a new pair would be the way to go. Cost is from £343.70 plus post & VAT or £230.22 plus for the non-adjustables.

Looks like they don't want to sell bits - makes a mockery of saying these are rebuildable, no need to say I shan't be buying a new set. Shame, but that's how things are these days I guess.

 

After replying that "rebuildable" was not a very apt way to describe the ikon shocks, and asking again for the price of spares, waiting some time, a nudge got this reply

Dear Mr Scourfield, thank you for your enquiry and apologies for any delay.


We are the new UK distributor for Ikon Suspension, having been recently appointed due to the retirement of the old importer.


Whilst we are a long established technical motorcycle parts company, Ikon is still a new brand to us and we are very much still in the process of learning, handling the handover, building stocks and making application and technical information accessible to our customers.

For these reasons, please bear with us, as there may be a slight delay.


We‘ve requested technical data and spare parts lists to enable us to help with enquiries such as yours. I see from the emails below that Norman had been in touch and advised replacement shocks due to cost of spares, etc, this was reinforced by the manufacturer who advises that although rebuildable it’s not always cost effective, once I have the prices I can advise you accordingly,

Thanks for your patience in this transitional period.


Kind Regards,

Steve.

It seems I may yet get a price for these shafts. In the meantime I'm looking at a set off a 750 from Germany, do they fit a 650 maxim anyone?

 

Anyone know the answer to this?
Thanks in advance.

 

So the question is, are 750 (seca or maxim, assuming they are the same length) a straight swap into the maxim, or are seca/maxim all the same length? What about the pin diameters?
Thanks

 

A few years ago when I needed to replace my shocks, I just measured the distance "eye to eye", then went to a wrecker and picked up some very sweet Honda shocks that were almost new and matched the same measurements as my originals. Cost me $100.
If you are a hardcore racer then spend big on shocks, tyres, fork springs, pistons, exhausts if you can pay it, but I ride to work and occasional hard rides so I focus on value not so much performance.

 

Thanks mrblackstock, i just did a search, which I should have first off:

Looks like they're all the same give or take a half inch or so, the 750 maxim could be stiffer sprung. I have a chance on a pair of used ikon adjustables, as usual the seller is not specific on what they were specced for, but the info in the link gave me the what I needed. Thanks for replying, the silence was deafening...

 

I know the 750 Maxim regular shocks are the same as the 650 shocks and only have a heavier spring around them. The other 750 Maxim shocks look like air shock, and may be. The 750 Seca shocks have a different top. I don't know how they'd come apart. I haven't tried.

But if you have compressor, you could swap your springs out for heavier springs......
