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.

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...

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.
