lowering a speed400

The two lowering spring collars, Metisse and Lust, strike me as ridiculously expensive for such a simple part. I note that one 400 owner apparently is a skilled machinist and has made one himself. I suspect that there is a very lucrative market here for a home shop machinist who wants to make a run of a dozen and "test the waters". This is not a part I'd want to have fail in use, so sturdy construction would be mandatory. A bonus is that the home fabricator has used himself as the test beneficiary.

I have installed the Metisse lowering flange on my wife’s Speed 400 and on my Scrambler 400x. I did the work to remove and replace the shock but had a local shop do the spring compression and fit of the flange. I also had them shorten the side stands to fit. I then lowered the front forks per amount noted on the instructions from Metisse. It works well and the handling is good. You can make your own if you know what you’re doing and want to take on the liability of a failure but the quality of the Metisse part and install instructions are worth the piece of mind for me.

How much torque did you put on the shock bolts and the fork bolts?

Good job!!! I am not afraid of the installation but how did you support the bikes. I am afraid to us a jackstand because of damaging the exhaust or something else. any help will be appreciated. i have quite a lot of equipment but nothing seems right.

I used a jack stand with a wood block to support the bike

I have just started to remove the shock when I ran into 2 pesty wire connectors. Is there some secret to unsnapping them. If you are from Europe you might not have them, as I think they are for emissions. If can`t unsnap them I can`t get to the nut. Sorry to be a pest but any help will be appreciated.

I have a '24 400x and had no issues with wire connectors when replacing the shock.

"Hi all I've just replaced spring retainer with one from Lust racing which has reduced ride height by about 30mm"
I don't understand how that "lowers" the bike. The shock is still the same length, it appears just the preload has been reduced. I can see where the bike would ride a bit lower as when the rider sits on it the bike will settle lower more as the weight will compress the suspension more due to the lessened preload.

How did you compress spring? What brand are your clamps

The Speed 400 is way too tall for shorter riders (like me). I have a -30mm shock absorber coming from EMC Suspensions in France. An expensive solution, I hope it achieves the lower height I need in order to be comfortable. I'm on tiptoes now.

How did your shock work out? I went the other way and switched retainer, and it is OK but not what I hoped for. I will say it is better, but for an older rider like me shorter would still be better. I will keep trying because I love the Speed 400 and almost everything about it.

The lowering worked well. I got about 1 1/2 inches. I also shaved the seat foam.
