How to Choose Fork Oil Weight | What Weight Fork Oil Should I Use | Partzilla.com

In this video from Partzilla.com, John talks to you about how to choose the right fork oil for your motorcycle. But to understand how different fork oils impact your motorcycle, we’ll start by guiding you through what is going on in your fork.
The right motorcycle fork oil viscosity will vary depending on how and where you ride. The suspension oil viscosity index will give you clues about the weight of the oil and how it will behave across temperature ranges. Two oils, with the same weight but different viscosity indexes, will behave a little differently from each other at the beginning of the ride and then begin to differ substantially as you build heat into the fork.
If you’re moving from the factory recommendation on your fork oil, make small moves. Minor changes can have a big impact, and moving to an oil that’s far off from the manufacturer’s recommendation might not match the application for which the bike was intended.

I bought a new 2003 V-Strom. Impossible to get a test ride, I was relying on magazine reviews. It was initially a love/hate deal. It made me realize that journalists are lying SOBs. One of the many shortcomings was the forks - undersprung and overdamped. Every bump in the road bashed into the frame, but when I hit the brakes hard, it dived so hard that it yanked the bars out of my hands. The cure was Progressive Suspension springs and switching from 15 to 5 weight fork oil. Don't rely on manufacturers to get it right.

[@hcteksnamuh]

Exactly the information i need.

[@Nc0184]

amazing good job tks with this tips

[@EazyMac]

Very informative video! I'm about to do a front fork rebuild for the first time and I've been researching which fork oil to get. This helps a lot!

[@PartzillaParts]

Glad it was helpful!

[@merrillclark5279]

Great video and explanation of fork oils and their inherent inconsistencies and how they relate to a viscosity index. I'll be checking VI online and hopefully I'll have answer as to which is the best fork oil for my 96 Road King. I learned some good stuff today. Thanks.

[@PartzillaParts]

Glad it added some clarity!

[@chargel1347]

thank you very much learn something new again:-)

[@ineedmorecarrots6063]

this is great my 3month old motorcycle bounces like crazy even on small road bumps i can literally push down my fork using one hand with relatively ease i guess a 10w oil will do the trick since im just a skinny dude weighing 55kgs

[@lifeandliving_01]

very good sir.

[@ProgressTanaka]

Thanks

[@toddboden972]

All I've been reading for a Honda grom is to change from stock oil to 20w. Not hearing any issue with handling or any problems. Hondas 5w is definitely too thin.

[@manakara9821]

The W is not weight, it is winter. The measured flow of the oil running down a slope at a certain temperature. It is measured cold not hot at normal operating temps. I think at 40f.

[@kiryllis5823]

40 Celsius, but otherwise all correct

[@snainshah1996]

Sir, kindly tell me iso 32 hydralic oil is suitable for yamaha ybr forks

[@itsprivate5623]

So whats the right viscosity for me. Im a 85 kilos rider and uses my motorcycle on everyday city use

[@Auto_motive06]

how much oil should I pour on my motorbike forks? (yamaha yzf r1)

[@justintaylor6870]

What's best for my 2003 Honda vtx 1800s retro spoke .

[@gaga0084]

When I bought OEM forks form you, those comes with the oil, ready to install?

[@louiegoodwin1775]

Can't get my fork caps to come loose. Any suggestion. I used a cheater pipe , impact gun , I'm afraid roll break or round odd the but??? Thayns foot the help 2002 VTX 1800S

Best fork oil for hero 100 cc bike ..15w or 20w??

[@davidevans2257]

Hi I have a 125 kmx wos the best oil for my bike please

[@nickburkard6500]

How much would I put in for a cr250 1994

[@MagnumMuscle1000]

Dampen=make wet Damp=reduce oscillations A fork dampens oscillations. A dampener makes something wet.

[@kkuhn]

Damps oscillations

[@dylancrow7919]

You messed up in your own correction.

[@chromevanadium5825]

For those, who need such videos the best oil is the one that is suggested by a service manual of a specific bike. That's all they have to know.

[@MoswenMedia]

Kind of gate keeperish isn't that? I'm doing my fork seals and would like to know which viscosity would match my weight the best since I'm a smaller guy.

[@elobiretv]

Yeah don't bother learning so you can pick the right one for you, just go with whatever the manufacturer decided to put in for a skinny 165kg rider...

[@FoodStreetRider]

I am from Pakistan and ride 150cc Suzuki Bike, company writes in their manual that use G-10 OIL for fork. Problem is that company dont sells the oil nor they have, so we in pakistan got SAE 10 is that same as G-10 ?

[@farrukhhasan7751]

Use automatic transmission oil. Rs. 1200 per liter.

[@FoodStreetRider]

@@farrukhhasan7751 no, i got ABRO shock absorber oil and Alhamdulillah it worked very well, i would say excellent

When should fork oil be changed.

[@W.O.C.]

Every 30-40 hours is ideal, but the longer you wait, the worse your oil gets, so more wear. 30-40 hours is like the happy medium though, so your suspension won't really wear.

[@W.O.C.]

@June@97 yeah. 30-40 is good.

[@46Bax]

​@@W.O.C.bro that's absolutely crazy, that's literally insane. pretty sure it's good for 5-10k km's

[@W.O.C.]

@@46Bax you mean like 5 to 10 kilometers? Cause I measure wear time in hours on my bike also I race on a track. Whoops meant 5k to 10k.

Ole or oil?

[@bmxtryhard]

always ole

[@thewrongbike7709]

We need to stop saying "weight". W does not mean "weight". It means "winter" I.e. the viscosity when the weather gets cold.

my manufacturer has no guidance on fork oil weight, this video is of absolutely no help to me. but if the manufacturer did have a guidance, then this video would be of absolutely no help to me. aka: this video is useless

[@user-iz2hk4tc6n]

OIL-WEIGHT What the f... is he talking about. ??? The "W" stands for WINTER, and could be translated to cold oil. So if I were to use a video on fork oil, look for Dave Moss instead.

[@cinnreds18]

What the F….. are you talking about? weight refers to the oil's viscosity, which is a fluid's resistance to flow. Oil weight is determined based on the oil's flow at a standard operating temperature of 100 °C He’s not talking about winter rating lol as in the case of 5w30. These are straight 5 weight fork oils and yes the term weight is used for viscosity measurement. If you’re gonna be a wise ass be good at it.
