Important Announcement


CHECK OUT OUR NEW CST BLACK EDITION LAMBRETTA REAR SHOCKERS CST17BE, CST17LBE and CST17S2BE

CST BLACK EDITION ALLOY REAR DAMPER 310MM S1-2-3 Product Code: CST17LBE

The CST fully adjustable alloy rear shock absorber have been developed over the last 10 years both on and off the track. These are able to be adjusted both on the spring preload as well as the damping, with a larger diameter shock absorber piston, these are a brilliant upgrade even on the standard machine, especially due to sensible size external diameter springs meaning they easily fit to your Lambretta. 

These unlike some other adjustable shock absorbers on the market are able to be fully rebuilt and refurbished, meaning this will be the last rear shock absorber you will have to purchase for your scooter. 

They also come with a 2 year warranty.

The damping is adjusted by the rotary knob at the base, clockwise to increase damping, etc. It adjusts both compression and rebound damping at the same time in a fixed ratio. Our standard setting is between 5 and 8 clicks from fully anticlockwise; please set according to your preference. It has approximately 13 positions.

In general the more preload used the more damping is required. Carry out adjustments slowly and get used to the changes. One step at  a time is the best way to arrive at decent settings.

PLEASE NOTE THAT THIS ITEM DOES NOT INCLUDE A SPANNER BUT IT IS AVAILABLE AS AN OPTION OR YOU CAN BUY IT ON ITS OWN 

Fitting Instructions for CST Rear Shock Absorber

To get the best performance out of your new CST rear shocker, there are a couple of things you need to do after fitting.

back off the damper adjustment to Zero(anticlockwise)Set the spring height

To do this you need a friend with a tape measure

Firstly, measure the length between the centers of the mounting studs for the shocker, say 300 or 310 etc.

Secondly take the bike off the stand and sit on the bike with your feet off the floor so your full weight is on it, get your assistant to measure the distance again, you are looking for 15mm or so LESS than your first measurement. If this is correct you can go to the next step, if not then you need to either increase the tension on the spring by screwing the collar towards the top if the measurement is greater than 15mm or decrease the tension by crewing the collar towards the bottom if it is less than 15mm.

Thirdly once you have the spring height correct then you can adjust the damping, start off with it on an average setting 9 clicks is a good place to start, then you need to go for a ride so you can either increase or decrease the damping to suit the way you ride.

If you are going to ride 2 up, then you need to increase the spring load further as obviously the extra weight is going to affect the way the bike handles and will also crucially keep your ground clearance at an acceptable level.

If you don’t bother to do this apart from the handling not being what it should be you run the risk of damaging your exhaust and possibly the cylinder etc. that it is mounted on.

So it’s worth taking the time to check this out

Finally, we hope you enjoy riding with this excellent shocker fitted to your bike
