Hey!

I've just bought a Buell S1 -98 (love it!!), but i'm afraid it's a little too big for me at the moment. The seat height is well over 800 mm, and reading the specs, it should be about 750 mm from the beginning... Does anyone know how to lower it? Adjust suspension?

Would be REALLY thankful if anyone knew! : )

Hi, you can use a bent front shock mount from the X1.

Hi again!

"you can use a bent front shock mount from the X1"

Yeah, but I mean the bike is originally 749 mm (new)... and now it is 850 mm, so someone made it higher without changing too much. It is the same shock and everything as original...

If you got the owners manual it should have a section on "setting sag" in the suspension setup area. Basically there should be a threaded piece coming out of the rear of your shock with a locknut. You should be able to thread that back in to the shock, shortening the shock and lowering the bike. Be warned - raising the rear is a good way to increase turn-in response in turns. When you lower it back down, you are going to have a less responsive (but still great handling!) turn in from the bike.

Jess:

There used to be a lowering kit made that incorporated a modified shock mount.

I'll ask about and see if I can find any.

Thanks a lot!

Now I've been doing some research. My bike has the tube frame... And with that locknut all the way back (to the right) into the shock, it's much softer but still 850 mm high. I must be too light weight But I think that if I get a "longer" shock (spring?) then maybe it will get normal again...

Like I said, use the bent front shock mount.

It's possible you have the wrong mount with the wrong shock (for example - the later (bent) shock mount with a later (16") shock ... I'd look to make sure you have the correct parts on it before throwing other parts at it ...

What length is your shock from eye to eye ? if it is 14.5" you need the later model shock mount (bent), if your shock is 16.5" you need the early shock mount (straight)... (I may be off by a 1/2" on either of those measurements - but you will know which you have when you measure it ...)

Just make sure you have the right parts on it now ... You never know what the previous owner did to it .. also - like Ratbuell said - check the sag settings after you make sure you have the correct shock/shock mount combo ...

Thanks a LOT everyone! Now I get it. Just have to fix it. It is the long shock (16.5") and the straight mount... So it's kinda strange that it's high like this.

Gonna get that bent mount anyway

THANKS!!

"Like I said, use the bent front shock mount."

Don't do it. Don't use the short shock mount with a long shock.

Using the short front shock mount (the banana shaped 'bent' one) with a long shock is probably a bad idea - it's certainly not how the factory lowered the M2Low models. With the 2:1 (approx) leverage ratio of the swingarm, a 2" difference at the shock mounting equates to a 4" difference at the rear axle. This may let the swingarm go beyond it's range of motion and may also let the exhaust crash into the ground at full compression.

Get the lowering kit suggested by Court or get a shock from an M2L (and appropriate mount) and make the necessary mods to shorten the travel of the fork.

If you can find more than 1 kit please keep me in mind. The S-1 I just picked up is a little too tall for me.

Set the shock preload according to your weight. It is not a ride height adjuster.

Like it's been said, using the "bent" mount WILL give greater suspension travel than the available ground clearance would allow. Not only will the exhaust get beat-up, but the rear of the shock will bottom out hard, too. Definitely a dangerous condition.

I don't know if this link is still good but West Tek makes a 1" lowering shock mount. I have an early aluminum version, but alas, I modified it for stock travel.
