Who has the lightest Street Ninjette?

As a general proposition, the best mod you can do to your baby ninja is to reduce its weight. Extra points for reduction of rotating mass.

Just weighed my 08 250r on a calibrated industrial scale. Mine has all of the street stuff on it: lights, wiring harness etc.

320.2 lbs with a FULL tank of gas.

Gas is 6.3 lbs/gallon. The 08 version has a 4.7 gallon tank. Empty my tank and my bike weighs +/- 290 lbs.

Let's hear some of your measured weights.....How low can you get these suckers?

I'm aiming to get it to 310 Fully wet.

To do: replace the Galespeed Forged Aluminum Wheels with BST carbon wheels, replace the 520 chain/sprockets with a 415 setup. That should get me 7 more lbs. Need three more....

Anyone want to buy a set of like new Galespeed type S forged wheels to fit the 250 or 300? They're gold anodized and are 11lbs lighter than the 08 wheels. 3.0 front/4/0 rear.

If you happen to have original wiring, there's a meaningful amount of weight you can lose. Just takes a bit of re-designing. And you can go crazy and replace it all with aluminium wires.

Probably the guy with the Italian rims, he was trying to make it as light as possible… I doubt I’d ever spend that much on two rims

I've contemplated a zero budget wheel mod. Grind/sand clean all the casting marks, texts, rough surfaces. Maybe round off some sharp edges. I might do one and see where it gets me.
When I was putting my E30 back together, I had in stock multiple rear windows. I chose the lightest one, by a significant margin. Same thing with some other parts too. My point, there's many ways to lose weight even without a sack full of cash.

LOL....My 2012 250R is closer to the 400lb mark or a bit over ...and I've added weight to that....a rear rack and a top box and a set of sliders but that is a noble gesture, to get the bike as light as possible !
it's all about the power to weight ratio in the end....
I once had a bike that I stripped everything off of it and just ran with a plastic bottle of gas and rode it up our dirt road... it was noticeably more powerful than it ever was before ! (it made a whopping 12 hp if I remember right) but the thing was not that impressive with everything on it
but stripped to the frame changed that bike noticeably I bet I took off 100lbs of stuff ...I was making a street bike into a dirt bike because i could not get licenses for it.... made a World of difference in it's get up and go ...i eventually put the gas tank back on it and the seat as sitting on the frame was painful on that road ! .... it didn't last too long but it was a blast for a while !
lol....
