You enjoy that cake TNC and have a slice for me.

Waiting for Deej to "weigh" in on this thread.

 

Look at a lighter battery and pipe. Two big areas for weight lose. That is suspended weight that is high on the rear of the bike. Aluminium rear sprocket with a non o-ring chain and a lighter rear tire sure brings the bike to life. there is not a lot of horse power with this bike so if you have a heavy rear tire and sprocket with an o-ring chain it really sucks the hp out of it.

that my 0.02 cents.

 

With a full FMF exhaust, super lightweight battery, no signals, mirrors, rack, or any of that rhubarb on the rear fender, my KLX weighed in at 275 lbs. I probably could have pulled a few more pounds off it, but not without looking pretty hard. There's a LOT of wiring on a KLX, and wiring is heavy.

 

What about the coolant overflow tank and all the emissions crap? Radiator fan? A guy could fab up an aluminum airbox, the plastic one is a pretty good chunk. Depends how far you want to go and what you are willing to compromise for weight loss.

 

Holy crap..2 pages..I gotta read..

 

Ok, well now that I've read everything..Let's get down to business.

What I've done so far

Flatside carb + podish filter (So airbox removed! less weight!)
Flush mounted rear blinkers
Aftermarket removable front blinkers
Cyclops headlights (detactable with 2 bolts)
Aluminium rear sprocket (not sure about the no O ring chain)


What I"m looking to do

I was looking at the Twin Brothers
Two Brothers V A L E M 7 Aluminum Slip on Exhaust 06 12 Kawasaki KLX250S SF | eBay

That should drop some weight, but is the FMF lighter?

Also which battery do you suggest? Also, can the coolent overflow be removed, or is that highly suggested to stay mounted?

Lastly, I was gonna ditch the normal instrument panel anyways for a light weight model I can mount on the bar and call it golden.

Trail days I'd strip her naked as much as possible anyways. So that should clear it up right?

 

All i know is the fmf is quite a bit lighter than the stock exhaust but the twobros m7 carbon fibre is way lighter than my fmf (half the weight) not sure if their is much difference with the aluminum m7 & the fmf.

I was recommended 2 batteries that both weigh about one pound & have more cranking power:

Shorai Lithium Ion Standard Motorcycle Battery - LFX09L2

KLX-250S Ballistic EVO2 4 Cell (100-010)

 

Cheers I'll check those batteries out.

I was looking at the Twobrothers because of the weight + the overal size. They are a couple inch shorter than the FMF which allows the rear plastic to provide better protection from dings and dents. That was my main reason..lol I don't mind falling, but I'd rather get things that will last a bit longer

 

I can not believe no one here mentioned the brick of a gas tank

you can drop almost 7 pounds getting rid of the stock tank and add 1 extra gallon of gas i purchased the IMS tank it fits like a glove

when full the weight is a wash but you can go farther

 

This thread piqued my interest so I just went out to the garage and weighed my 2004 KLX300R. It's dualsported with mirrors, etc plus protection like skidplate and handguards. That's with the stock 300R muffler - I took the FMF Powercore 4 off due to it's loud nature.

125 front/135 rear for a total of 260 wet. That's utterly full of gas because I just filled (actually overfilled) it up this AM and drove 3 miles back to the house. And that's with the 300's larger (2.6g) tank.

I had thought it would be about 260 because my 07 250S was 290 in the same trim.

So, if you like thew KLX platform but want it lighter, the 300R is cheaper ($1200 for a great condition 2004) 30 pounds lighter and 5 horsies more. Downside - it needs a good kick. Upside - 2004 and later are stinking easy to kick. Throw a $160 Tusk dualsport kit on it and rip.
