Questions and Answers about lowering kits, jack up kits and motorcycle geometry
HOW DO YOU MEASURE THE RIDE HEIGHT CHANGE?
Manufacturers report the ride height change in different ways, we at Lust Racing measure the ride height change
vertically above the rear axle. This is the most accurate way the measure the change. On most bikes the seat height will
change approximately the same amount. Based on the feedback we have received from our customers we are confident that our
ride height change information is the most accurate in the industry. We are also able to calculate what link lenght you may need
to achieve a certain lowering / rise. If you are looking for a different ride height than specified in our listing please contact us
we can supply links in alsmost any length with very small increments. At Lust Racing we work continuously to bring out new products
to the market. If we do not have a kit, and there appears to be a clear demand for it we are very likely to bring it to the market.
Drop us a line if there is a certain link length you need. Please use our web-contact form.
ABOUT CHANGING SUSPENSION GEOMETRY
Motorcycle manufacturers designs their bikes for the average rider - in terms of lenght and rider mass - whatever that "average" might be. Some newer sportsbikes have
very high seat and ride height. The factory seat and ride height is a compromise that will not be perfect for every rider - in fact most riders will either
be longer or shorter, heavier or lighter. Motorcycles are also made and used for various purposes, in addition rider
preferences varies depending on riding style and use. Manufacturers try to make a compromise that will be good for most. This means also that
it will not be ideal for everyone. Motorcycles comes in very different styles and designs, the rake and the trail varies largely depending
on the style, make and purpose of the bike. With our adjustable rearsets, lowering and jack up kits you can make your bike fit your measurements, your riding style,
to enhance the bike for your purpose of use. Changing the suspension geometry when made correctly is a safe modification that greatly can improve the riders confidence and riding experience.
WHY STEEL LINKS?
Lust Racing manufactures suspension links mainly out of steel because suspension linkages need to be strong, simultaneously oscillating
mass is good to keep as low as possible. We make suspension links that will outlast your bikes lifetime.
Nobody want to experience a suspension linkage failure - we do not even want to eloborate what could follow from link failures.
Why not alloy links? - Alloys languish under pulling force.
Suspension links are constantly moving during the suspension movement, versatility and tensile strength is therefore extremely important.
Alloy links need to have needle brearings and sufficient material to gain the same strenght as steel links (about twice as much thickness is required for
of an link made in highest quality aluminum). Alloys need to have high quality bearings to withstand the wear. We strongly advice you to think
twice before you fit a alloy links without or with only brass bushings to your bike.
At Lust Racing we do not put our customers at risk our suspension links are made to last a lifetime. When alloys are used we fit our links
with needle bearings to prevent excessive wear that otherwise will occur on alloy links.
SHOULD I GO FOR A 25 OR 40 mm KIT?
In general we recommend to start with a more moderate change, the higher you lift the bike the larger the difference, notice also
that this is not a completely linear change as the higher the bike is lifted the angle of the swing arm changes more for each unit of
change the higher the bike is lifted. Note that when you fit a jack up kit you may like to extend the sidestand. Similarly when fitting
a lowering kit you may like to shorten the sidestand. With moderate changes in ride height alterning the side stand is optional. With larger changes
it should be done. The easiest way to accomplish this is to (cut) the side stand to shorten it. To extend cut and weld extennsion to it.
You can get a used sidestand from a scrapper for abround £ 15-20 should you ever want to change the bike back to normal ride height again,
(usually when selling the bike).
DOES MY BIKE ALREADY HAVE A LOWERING / JACK UP KIT FITTED?
I purchased my bike used an I do not know if the bike has been lowered/jacked up earlier. Can you tell me the lenght of
your lowering/jack up kit? The best thing to do is that you measure the links fitted to your bike, and tell us how much you would like
to rise/lower the suspension from its current level. We can based on your link length confirm if your bike is fitted with standard suspension links or not,
and calculate the link lenght you need to achieve the lowering or rising/jack up you require. Remember to specify you bikes make, year and model, plus the link
lenght measured from hole centre to hole centre along with the infomation of how much you would like to lower or rise the suspension.
I DON'T FIND A KIT FOR MY BIKE LISTED
We may still have a kit that fit's your bike if you provide us with some information: Mention make, year and model, wether the bike
is fitted with straight, bent or cureved suspension links, hole to hole distance and hole diameter. Don't forget to include how
much you would like to alter the ride height rise/lower the bike.
"YOU DID SEND ME THE WRONG KIT"
LOWERING LINKS should be LONGER THAN the STANDARD LINKS. This is because most multi-link suspension systems has a rocker arm that reverses the suspension movement
mechanically. We double-check each and every order we dispatch, it is very unlikely that you got the wrong kit from us, if that would have
happened against all odds, do not worry in such unlikely event we would replace the kit without for FREE, but PLEASE READ ON.
JACK UP LINKS should BE SHORTER THAN the STANDARD LINKS due to the suspension rocker arm that reverses swing arm movement mechanically before the shock.
The rocker-arm is pivoted and more importantly the rocker arm has arms of two different lengths in other words a mechanical ratio.
"THE LINKS YOU SENT ARE OF THE SAME LENGTH AS ON MY BIKE"
Before we answer this question we give you first a technical brief, please read it. Because of the suspension rocker-arms ratio the ride height change will not be equal to the difference in suspension link lenght.
This means that a much smaller difference in link length will translate into sa significantly larger change in ride height. On some bikes
it is even hard to see the difference with the old links still in place. Only a few millimeter difference in link length changes the ride height a lot more.
So if you ordered a -30mm lowering kit, the links should be longer, but NOT 30mm longer than the standard ones (due the suspension rocker arm ratio).
Similarly if you ordered a 25mm jack up kit the links should be shorter than the standard ones - but not 25 mm shorter (due the suspension rocker arm ratio).
CHECK CAREFULLY AND MEASURE THE LINK LENGTH FROM BOLT HOLE CENTER TO BOLT HOLE CENTER. If you got the right kit, as we still are inclined to believe,
you will now notice that the links we provided are actually of different length than the ones on your bike. This is also EXPLAINED in the INSTALLATION INSTRUCTION,
PROVIDED WITH EACH KIT, PLEASE READ IT if you did not do it yet. We would encourage you to measure the link length again to save both your and our time. If it turns out the links really are of the same length
feel free to contact us. If we have supplied wrong links for you we will replace them free of charge, we will even cover your return postage (UK only).
Before you return a kit please contact us first using the web contact form or drop us an email to sales AT lustracing.co.uk - this as we want to make a few checks to aviod sending the same kit back and forth.
Do not worry, you are covered if you really got the wrong kit from us.
We will respond to your message ASAP (As Soon As Possible) - please include make, year of manufacture, model of your bike, description of the problem, measurement
of your standard links and the links we sent to you both measured from hole centre to hole centre. Note: Do NOT measure overall link length as the outer radius
may differ on some links. Measure also the hole size diameter.

WHAT DOES "FOR RACING USE ONLY" MEAN?
"For Racing Use Only" is a statement to comply with international legislation, what it basically means is that if the customer intends to fit a kit
for road use anywhere in the world the buyer is liable to check that the kit is legal to fit in his country of residence. Lust Racing lowering and jack up kits
are probably the stongest on the market.
IS IT LEGAL TO FIT RIDE HEIGHT ADJUSTERS?
We make kits for racing use, however they can be fitted to street/road bikes. They are made to be as strong as or stronger than standard units
they replace and Lust Racing lowering and jack up kits are made to outlast the lifetime of your bike.
If you fit a kit to a road bike you should check the regulations in your country. For UK residents we recommend showing the bike
at a Motorcycle MOT centre. What is checked is that the rear wheel can move freely during the full suspension movement and that there is sufficient
road clearance. We recommend that you inform your insurance company about the modification after having the MOT check made.
We make our kits using hi-tech manufacturing and machining methods to high accuracy using high quality British Standard specification roll forged steel.
We can note that TUV approval is NOT required for the UK market and that TUV is a German private testing organisation.
Regarding quality we do supply kits among others to some Suzuki, Kawasaki and Triumph dealerships in UK and abroad.
