YSS Shocks, anyone used them?

[Mike711]

So my issue is I have a GS711, 1978 750 frame with 1980 1100 Kat engine/swingarm/forks/wheels.

The swingarm is longer than the 750 one & with the std length shocks results in less ground clearance, the forks are dropped through the yokes by about 4cm to allow clips ons to mount above the yoke. Moving the clip ons under the yoke isn't an option, there's no clearance to the fairing and I don't want to alter the riding position.

So I am looking at longer shocks and have seen YSS units that look okish & won't break the bank, has anyone used them & can comment good or bad about performance, quaility etc?

My second idea is to fit fork extenders to allow the forks to go back where they should be, does anyone  in OSS know where I might be able to get such things made or is there a longer stanchion from another model such as an L that would fit the Kat fork sliders?

Thanks in advance.

Don't you need to raise the front and back? Raising just the back will quicken the steering/reduce high speed stability and vice versa. I have not tried YSS shocks but have heard good things about them from people who have. They also seem good value for money. What about some of those raised clip ons for the front? They may enable the forks to be dropped through the yokes whilst retaining the current riding position.

[Mike711]

Yes I think the front will also need to be raised hence the question about fork extenders although I wil try it with just the shocks first, if it quickens up the steering without compromising stability the front might be ok as it is.

The clip ons are Tomasselli  swan necks fitted upside down to lift the riding position, they won't fit below the yoke.

Thanks.

I had a Teapot YSS on my EFE, because I was (and now again am) running a shock from that.

It was brandnew but the rebound adjuster already had play in it, it felt like a bicyclepump and the bike sat about an inch lower with the preload wound right up.

Took it off within a week and sold it on.

We, and lots of other teams in our race series, run a YSS shock and we've not had or heard of any problems. If you got through a distributor who is also a suspension specialist they can build it to your spec re length, spring etc. Regarding fork extensions, depending on what adjusters you have in the fork tops, they're not too hard to get made. I'm not actually a great fan of them but I do have a pair in the 916 legs in my B12 and, at 40mm , you can probably do the same as I have and have the joint covered by the clamping area of the top yoke. 

I believe YSS are owned by Ohlins which can't be a bad thing.

I'd probably talk to Hagon.

YSS do an insane looking aftermarket USD and RWU radial braked fork though

One of the fellas I raced with is a fan. They are "almost" bespoke pieces and he bought a couple of sets for bikes he doesn't even own yet... yet?

My teapot YSS is not that bad but I like the hyperpro on my 1100f better except the way to adjust the spring.

I've got YSS on my 7/11 and also on my 425. Love them. They do err on the comfort side, but with the roads up here that's welcome.

A mate bought some for his SR500 on my rec and they're great too.

All of the above are their budget cheapos, so nothing fancy.

Hagon on the other hand have been patchy in my experience...sometimes great, other times terrible. I went through months of sending shocks an springs back and forward to them trying to find a good set. very helpful, but ultimately, everything they had was too harsh.

Does your 711 have a std swingarm or an 1100 unit? If 1100 did you go with longer than std & did it make any difference to stability?

I've got a Metmachex from a GSX750 which is about 25mm longer.

The bike is much more stable than the standard bike, but how much of that is the swinger, and how much is the slabby wheels and forks, I don't know as I changed them at the same time.

Got YSS on mine,had them on my ET before as well,had no issues with them

Thanks, yes the forks/wheels may have an impact on yours, mine is 1100 Katana forks/wheels/ SA etc & is rock steady but sits too low. I am thinking of CB900F shocks which are approx 30mm longer and have the fork lower fitting, I'll see if they make it twitchy & possibly add the fork extensions later.

[Peterrr]

I've got YSS adjustable shocks on my katana and I am very happy with how the bike handles.

[Mike711]

I went with Nitron in the end, lifted the rear by about an inch with a bit more available via the adjuster. The bike steers a bit quicker but nothing that's going to be unstable.

Yes, I have a set on my Katana. They are a good shock. I got a a longer clevis machined up to extend them by 35-40mm.
