Hello everybody, I'm Scott and I have a few scoots. Allow myself to introduce themselves.... 
I have a 1965 Vespa VBB
a 1965 Lambretta Series 3
a 1957 Lambretta LD
a 1986 Vespa PX
I will be posting a question about shocks for the PX, I'd appreciate any feedback. I guess I'll post it here, and maybe see if there is a better spot to post it also.
Anyway, it's a PX200 and I put a Polini (kick side) exhaust on it on New Years Day. Later than day, my girlfriend and I were riding very slowly down the sidewalk and then down a very graduated kerb.....when the front tire went down first, the scoot became lower to the ground, then there was about a 2 inch piece of the sidewalk sticking up that caught on the exhaust and brought us to an immediate stop. It was quite unpleasant really, I hit my knee on the legshield toolbox, jammed by right shoulder and my teeth slammed shut. (this was a very slow speed too) It put a massive dent in my exhaust which had to be cut out and replaced.
So, to get to the point, after that incident I put on new Sebac shocks because I felt the old shocks were worn out and also causing the scoot to be too low. The problem is the new Sebac shocks don't seem very strong/stiff either. I've not yet ruined the exhaust again, but I'm worried I might when riding 2 people. I'm a big guy (about 112 kg, and my gf is pretty normal). The front Sebac shock bottoms out very easily with 2 riders, and a little less so with only myself, but still does in quick stops or bumpy roads. (I know it's not really "bottoming out" because there is a rubber stopper that is part of the shock which is what it's hitting, but still, it's hitting that all the time and I can definitely hear it) It hits mostly when I use only the foot break, the front nose dives, compresses the Sebac completely and hits bottom. If I use the hand brake and foot break in tandem it doesn't as easily bottom out. However in emergency stop situations the foot break is ready to go and it takes more time to get the hand around the hand brake. So, in these situations the scoot is usually stopped only by the foot brake the the hand brake coming a moment too late.
Is this common for Sebac shocks considering my weight and 2 riders? Or are my shocks likely defective or no good? I'd like to be able to stop without the massive nose dive that compresses the shocks, ie....I'd like stronger springs.
Any ideas gang?
Thanks
Scott Dean
