Lowering Front Shocks

Lowering front suspension on motorcycles offers ride height improvement and drive ability, but this depends on how we approach to do it. Some uses the slipping method in where the telescopic tube is adjusted from the locking nut of the T-post as shown, I just really dont know how secure this approach, because of the tube may slip from time due to heavy bumps on the road. If you will analyze the tube, there is a groove
for the first bolt to secure the telscopic tube not to slip off in its place. That is what the groove stands for. To lower the fork the right way, we need to understand what makes up the front fork, how they work, what components that makes the whole front suspensions.
By dismantling it although i have troubles removing the damping rod bolt at the end of the fork looks like this part by part. CONTINUE reading........





Anatomy of front fork suspension that uses damping rod fork (orifice damping)

Photo shown is what made up a damping rod fork suspensions that bikes of today uses. cheaper, easier to maintain.The most common fork design is the damping rod. I know, I know: damping rods? Why damping rods? If you understand damping rods and their limitations and solutions, it will be easier to understand cartridges. Once you understand cartridges, it will be easier to understand shocks. This way, once we get to shock design it won’t take much effort to cover the subject.
    Damping rod forks have been around for years and today can be commonly found on most cruisers, standards, trail bikes, dual-sports, minis, and most vintage bikes. Damping rod forks are less expensive to manufacture but don’t offer much sophistication in the way of damping control.















Ok knowing what part and how the fork looks like..its time to how to lower it without changing anything but Adding just one piece of spacer to lower it at your desire height. where to put it?...It will be fitted in between the damping rod and the top out spring as shown. after inserting will look like this
spacer in placed. and we are ready for the assembly to find out how the 3/4th length spacer do the job.
The difference between with spacer and no spacer front fork suspension. Then we can put the back the fork at its normal position on the T-post without sliding the groove out that protects the front fork slipping when heavy bumps occur.

?much better than the sexy bolt....hows the play? mas matigas ba? or should i add more oil so it would be more like the stock height

LEI said...

Drained the oil first to see how much will be poured back...actually its for my scooter posted, the ride height was terrible too high. so i immediately came to my senses to lower it but then dont want to just use the slip method..120cc of oil was drained i just pour 100cc of fork oil, same play as before in a lowered version...the spacer is of your choice my friend...if you need assistance just buzz me thanks

Do you have to drill a hole in the spacer since it goes between the damping rod and the top out spring?

I have a spare fork tube/inner tube that is good as trash I am planning to cut it to an inch. Can that serve as the spacer?

LEI said...

if the spacer do not get on the way of the damper rod holes then there is no need to drill holes...just make sure the spacer is exactly the diameter of the top out spring. make sure also to lessen the oil...mine was from 120cc of fork oil originally down to 100cc but i felt to stiff so i removed another 20cc and now its rebounding as if it was the un treated front fork...

sir may I ask if the spacer is made out of stainless tube that's like the diameter of the top out spring? I want to lower my front fork without using the slip method. can you help me sir? thanks in advance :)

LEI said...

stainless is the best to use in these method, for it will not rust inside...since im out of resources, i used galvanized iron, do not use any metal that are prone to RUST, it might contaminate the fork oil...

im planning to have mine 1.25" lowered. i've already fitted my dummy spacer ( as i still need to find the right spacer ) but my concern is the spring, it seems longer this time. do i have to cut it? or should i just apply much pressure in setting it in (which may be very difficult)
thanks.

Vincent Minoza spring does not matter if it is too long or not..it will compress once the lock CAP is in place, though the tension will be much stiffer, you have to lessen the damping effect by pouring less FORK fluid, to counter balance the effect.

Where can i get the spacers? I want to lower my honda click 125i front at least 3inches since sliding down the fork will contact with the ecu

anung size ng wrench na pantaggal sa (bolt that secure the groove)?

Kenneth Dominic Zapanta said...

Sir yung spacer ba mabibili lng yan o pinamachine shop mo?

Sir ano ung kasukat ng inner spring ng shogun pro.ala n kc mabilhan ng bago.parehas nya kaya ung sa wave 100
