What is the easiest way to reduce the weight of your motorcycle?

I think it is the battery. Switch to a lithium ion battery. You immediately gain like 5+ pounds weight reduction.

Note here I said easiest. The cheapest is to go on a diet of course. What are you opinions?

If you have money, it could get easier. Itll become $$$ and you may start to worry about using it as a street bike. Light battery. Full exhaust. CF wheels. Ditch lights, mirrors, emissions/evap stuff, etc. 1/2 tank of fuel. Diet isnt necessarily easiest, but definitely a good way.

Just kinda depends on money youre willing to invest and what youre still trying to accomplish with the bike still. Street. Track. Racing. How much you care about "road legal-ness"

If you want to loose bike weight it all depends on $,
1-lightweight battery
2-ti link pipe and end can
3-ditch your pass hangers and fit a/m end can hanger
3-vortex fuel cap
4-if your bikes ABS replace all brake lines with a/m(you have no idea how much the oem junction points weigh)
5-Mikey moto rear disc
To move into your next bracket of weight loss will cost thousands but I'm talking in the 25kg to 30kg+loss

I'd have to disagree.... a diet IS the easiest... all you have to do is NOT shove food in your pie hole. ;) And it SAVES you money... easy X2. Add in cardio and you can be a double threat.

Aside from all the good answers up there, $$ are the magical mass reducer. You should have a plan & a goal, and review each an every single part that doesn't fit that plan. The old adage that it's easier to lose 1lb in 10 places than 10lbs in one place could take you further if you are on a budget.

Reliability gets to be fun too... you'll appreciate the 5lb weight loss from a cheap battery when you have to push start it on a cold morning. ;)

Lithium Ion batteries aren't cheap a good one is like 400 bucks.

What I'd love to see is something along the lines of a ratio. weight savings to effort required in total minutes. For example,

1) Lithium Ion Battery
a) 5 lbs : 5 minutes = 1.0/minute
2) AM Exhaust Slip On
a) 5 lbs : 60 minutes = .08/minute
3) Vortex Fuel Cap
a) .25 lbs : 10 minutes = .025/minute

I'm just guessing at the amount of time required for 2 and 3, I've never done it... Anyone want to create an actual list?

My goal here is to see let's say the top 5 or even 10 modifications that have the highest weight savings to effort involved in minutes. I think it would be interesting to see. Weight savings per dollar would be cool too.

Around $800aus per kilo at a guess if I averaged it out,To give you a time ratio with weight saved would be something you would have to do at the very start!I did write down what the oem part weighed against the replacement parts

This is too general. What are the top 5 or 10 mods, indicating weight savings per minute of effort for each mod? Certainly battery has to be #1 if you switched to lithium ion.

Estimate man, you've done it, and your estimate is far superior than anything I could guess at.

Ok, Ill bite. Whats the deal with weight reduced per time?

Because I don't know wtf i'm doing, and the ratio of weight savings vs effort involved is highly valued. I.e. weight savings vs complexity...

For me, switching the battery to lith ion is incredibly simple, and has a relatively speaking huge impact on weight for effort involved.

I can appreciate where youre going with that idea, but do keep in mind that everyones wrenching abilities are different. Also, depends on what Gen bike you have too. I can tell you that in my Gen 1, and probably its the same for Gen 3, 4 and 5, a slip on can be changed in about 5 minutes. Usually takes me longer to gather the 3 wrenches I need than to actually change pipes.

Aside from just generally trying to bring the weight down, what is your actually goal for the bike? Are you doing some type of trackdays/racing or do you just want a lighter street bike?

Honestly Gen-Eric that's a big ask mate and would take some time trying to get what your asking!you are correct with Shorai battery being the quickest but as for the rest for me a lot of work!best weight loss for performance gains!Dymag carbon rims!most costly and time consuming with minimal weight loss!changing out over 330 oem hardware to Titanium!2-3 kg weight loss and hours doing it!well over $3000 prolly $4000!dont want to write it down as my wife could see

That's perfectly fine. Estimate your time, and estimate your wrench ability. I'm ok with that and I'm sure a lot people that do not have the wrench experience will be cool with it as well.

I estimated 60 minutes for me to replace stock exhaust with a slip on. You estimated 5 minutes. We can actually build a top 10 list with an overall estimate based on each individual estimated time and wrench ability average. It just takes data... Lets get some data.

I think this would be a value add for the site as a whole. Obviously I'm not going to give an estimate on something I've never done.

As with any data collection effort, the value of the data is only as good as the data that is input, so be honest.

You can msg me with any questions on weight savings and time doing it!I will point you in the right direction as I have shaved some weight on my gen4

Price / minute is a secondary, primary is weight/minute. I.e. determining the complexity involved in the weight savings so people without wrench experience can determine the easiest approach for the most weight savings. I.e. people can prioritize the work they want to do, in the order they feel most comfortable with.

I think the info should be public, and would greatly assist any riders without wrench experience like me.

Check out the thread "trading money for weight"there is some information in there with what areas and weight loss!there is a lot involved in what your asking!its taken me years to get big numbers and to put that on paper is nuts!a list from 1-10 can be done but everyone has different skills and $ figures doing these mods!if it was simple I would do it but it's far from that.

But it's not as difficult as you say. Forget money. Just focus on the amount of weight loss you gained, and the amount of effort involved in minutes.

In my company we track similar statistics, although it is only effort involved because we have no metric to track impact. In the case of this thread and my initial request, impact would be the weight reduction which makes compiling and assessing the data much easier. Thus weight reduction vs time spent in minutes (or lbs / minutes) (or kg / minutes) is completely possible when averaged over a large sample from a community.

I say top 5 mods because the top 5 would be the easiest to estimate your weight to time. Going deeper to lets say top 10 would involve multiple interconnected modifications, but even that is not beyond the scope of this request.

Off the top of my head:

1) Battery
2) Slip On with cat
3) Slip On without cat
4) Full Exhaust
5) Tail eliminator
6) carbon fiber rims
7) stock mirrors
8) rear sets
9) chain adjusters
10) etc...

Ok I will say it another way!how can I remember the time it took to replace oem front calipers to Brembo gp4rx calipers and changing the M8 bolts to ti that holds the 2 piece Brembo together 21/2 years ago!no its not as simple as you say

It is as simple as I say. If you can't provide good data, then don't provide the data. Simple. Be honest. If you are not able to estimate the time then don't estimate the time.

That said, I understand that this site does not have enough people modding their bikes at any given time to provide enough data within any reasonable time frame to provide a valuable result that could enable non-wrenchers like me to prioritize their time in order to reduce weight of their bikes for increased overall nimbleness, acceleration, and braking.
