Chain guide, top (upper, slipper) chain adjuster kit, MB

MRB0006K

This MRB design is probably Mark's most copied invention, invented way back in 1987 and is probably the most copied part ever made for a Lambretta.

Always insist on genuine MRB parts and not copies.

This item is essential in any tuned scooter and we recommend it even in a standard scooter.

This chain slipper evolved because we found that the standard Lambretta top chain slipper wasn't strong enough to do its job in a Lambretta engine and can be quite dangerous when it snaps.

We recommend leaving about 6mm play (total up and down) in your chain.

People sometimes ask for a new piece of nylon for their chain slipper when it has worn down a bit but you do not need it - the rollers of the chain will run on the nylon.

We have never seen a chain wear all the way through the nylon on one of our slippers.

These are also known as chain adjuster or chain tensioner.

Tips

This question is often asked.

'If Im using an after market top chain guide/slipper do I fit a bottom chain guide'

From our point of view as the ORIGINAL DESIGNERS there are two ways to look at it.
  1. If you have a reliable high mileage bike, built correctly with perfectly aligned quality sprockets and dont want to constantly strip your motor then FIT ONE!
  2. If youve always got your chaincase side off for a badly put together motor and adjusting the top guide or having constant clutch problems then dont fit one, its the same as a racer, you get to see if the top chain is loose and you can adjust it.
Baring in mind we see lots of poor chains fitted, mainly Indian, which can wear out and be so sloppy in a 1000 miles that the chain can wear into the casing on the TOP and BOTTOM (if no guide is fitted)

It is very important to DTI and shim up front and rear sprockets, never guess, we have see chains wear out in 200 miles, fitting a bottom guide would prevent casing wear on the bottom causing more damage  if you don't know what you are doing!
